Unable to access external USB Drives!

Q: Unable to access external USB Drives!

Hi I recently upgraded my PC to windows 10 and every since have been unable to access any USB external drive.

The laptop picks up the drives and acknowledges that they are there and working but they do not appear in file explorer.

I have looked in disk management and the drives are there and healthy.

The USB ports work 100% as i have plugged in keyboards etc to test and all the drives i've tried work with other computers.

I've tried everything I could find on forums that have worked for other people. I've reinstalled windows twice. Ran various disk cleanup utilities, checked for hidden drives etc.

I need to upload video files to my laptop to edit for work, so need to resolve this ASAP :/

Any help or ideas is greatly appreciated!

Thank you

Preferred Solution: Unable to access external USB Drives!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi, some people seem to experience this, particularly with Seagate drives.

You might try disabling fast startup, or plugging them in to a USB2 port

I have 2 ADATA 500 GB external hard drives. I plugged them into the USB port and the computer recognized them by name and installed the driver files. It assigned both of them a drive letter but then gave me a message saying that they needed to be formatted. I clicked ok since they are brand new drives and do not have any data on them, but the format failed to complete on both drives. I took both drives to another PC running Windows Vista and they were recognized and accessible. I even transferred a few files to them for testing purposes; however, when I plugged them back into my Alienware laptop running Windows 7 Ultimate x64, then I got the same error. If I go to the disk manager, then I can see the drives by their drive letter and they are listed as healthy with a primary partition but the file format shows as RAW. I tried to use the device manager and uninstall the USB Mass Storage Device drivers for each drive and then I unplugged them and plugged them in again and I would get a device driver installation message that identifies the drives by name and tells me that the device drivers were installed correctly and that my devices are ready for use but then a few minutes later I will get a message telling me to format the drives. Please help. I've run out of things to try. I can still access my iPhone via USB and my USB wireless mouse still works so I know my USB ports are good.

I have purchased, installed all of my pertinent programs and files, and have begun using my lovely new HP laptop. All is well but for one major issue.
The new laptop does not have an SD card slot. I did not think this would be a big deal, but it is turning out to be a major pain.

Background Details:
New HP EliteBook
OS - Windows 7 Pro SP1 x64
Full Administrator
I have been completely and miserably unable to access various thumb drives and micro SD cards via two different card readers. Each external drive that has appeared but not allowed me access has been on FAT32-formatted media.
The external drives appear in Windows Explorer as Drive F:\

When I double click the drive icon to view the files therein, I receive the following message:
"You don't currently have permission to access this folder. Click Continue to permanently get access to this folder."

When I click "Continue," I receive the following message: "You have been denied permission to access this folder. To gain access to this folder you will need to use the security tab."

When I right click the drive's icon, there is NO SECURITY TAB.

I have also attempted these same steps and received these same results after setting my UAC settings tab all the way down to "Never Notify me when"

I have also attempted to gain access to the drive and give myself the permissions that I should already have as Administrator via a Command Prompt.

After running via Accessorie... Read more

Hello MdmRptr. Welcome to the forum.

ACL refers to a Access Control List. This is a type of file security protocol.
Access control list - Wikipedia, the free encyclopedia

You may need to remove the ACL in order to access the files normally in Windows.

Looking up ACL brings up a lot of Oracle links. Are you - were you - using an Oracle product with these cards/files?
Using Access Control Lists (ACLs) (System Administration Guide, Volume 2)

If it was an Oracle product you could use the method to remove the ACLs here:

If you were using a Linux program you could start here to investigate the removal of the ACL in Linux:

First I've heard of ACLs. Maybe this info will help to point you in the right direction.

Any ideas what I should do here.....

I can attach and use external devices - but when I try to safely eject there is nothing there - in other words, right click icon on system tray but the device is not listed.

Any suggestions with what could be the problem here? Thanks

A:Unable to safely eject external drives etc

Have you tried opening Windows Explorer, right-clicking the drive icons and seeing if you have the Eject option from there?

Don't forget, you can always go into Device Manager, select the drive, click the Policies tab and choose the Quick Removal option.

Write-Caching - Enable or Disable

This impacts slightly on disk performance, but lets you remove the drive without going for the Eject option first.

Ever since I switched over to my new Windows 10 PC, I haven't been able to access my external USB 3.0 enclosures. They are all 4-disk enclosures by IcyDock (Black Vortex). On my old Windows 7 PC, all I had to do was turn it on and all 4 drives were detected via USB 3. Now on the new PC none of the drives are detected. I checked their site and they don't list any drivers so I don't think that's the problem. Any idea what I can do? I also have a couple older e-SATA external 4-disc enclosures and those are detected fine through my e-SATA card. So it's an issue with the USB 3.0 enclosures. Also, I have a Mediasonic brand 4-disc USB 2.0 enclosure and that works fine - all drives are detected. So it's just the USB 3.0 enclosures by IcyDock that aren't being recognized.

A:Can't access drives in external USB 3 enclosures

Did you try a new cord with the dock? Have you tried it with a different computer? If the USB hub is not showing in Device Manager as even a Hidden device, you may have to unplug the hub and reboot, then plug it back in. Also if it is not a powered Dock, you should power it, due to your new computer may not be sending enough voltage to power the device.

For some reason about 75% of the time when I have an external hard drive plugged in to either my laptop or desktop computer (both running Windows XP Professional SP3) it won?t let me safely remove the drive when I?m done with it; the error message I get on both computers when trying to remove the drive using ?Safely Remove Hardware? is: The device ?Generic volume? cannot be stopped because a program is still accessing it. Except no programs are accessing it, not even Explorer. I?ll then have to shut the entire computer off in order to remove the drive since nothing else seems to work.I did try the steps listed at this site but I still got the same ?Generic volume? error message after closing the two threads that were accessing the external drive and Process Explorer didn?t show anything at all as accessing it once I had closed the threads that were there. If it helps, the two threads were apparently the same thing at the same location: F:\System Volume Information\EfaData\SYMEFA.DBI googled that file/file path but didn?t really find anything that related to my problem. So could anyone here help me out? Like I said, this happens on both my laptop and my desktop computers which aren?t connected to each other in any way so in addition to wondering why I?m getting this message to begin with I?m wondering why I?m getting it on both machines.Any info or advice would be much appreciated.

I have had this system for over a year and no problems. A few days ago I could not access my dvd drives in xp. They are still assigned letters in my computer and the device manager tells me that both devices are working properly. I have tried every type of disk that I have. They will not autoplay nor will they open. I have not installed any new software lately. Everything else on my system works. I have a dual boot system, xp pro and vista ultimate 64 with each os being on a seperate hd. When I go into vista my dvd's work fine. I have downloaded the latest firmware for both optic drives. I can't play music from a cd or install any programs. My computer shows me that they are there but i just can't get in them.

Last night I decided to a through cleaning of my computer area.So I unplugged all my peripherals,cleaned the desk and bundled my wires so they didn't look so crappy,blew out a bit of dust and that's it.I then plugged everything back in and tried to boot,but could not.So I booted from my install disc and ran startup repair.It told me to disconnect any external hardware and reboot.It worked.
So I plugged in my Fantom 500g HD and my Western Digital 80g HD. Autorun immediately recognized both drives with no problem.The problem is that when I go to my computer and click on either drive,nothing happens....at all.
I tried to disconnect and reconnect the drives and once again autorun pops up but I found I CAN access my files through the autorun prompt....but that's the only way.

Any suggestions??

I just bought an HP Prodesk for the office with windows 7.  Whenever I try anything external (camera, hard drive, flipcam)
I get the same series of errors. 
First it says I don't have rights to view it and I need to click on the "security tab" to give myself access. 

Only catch, there is no security tab....(see attached photo). 
I did follow the steps here  to make sure I had the tab on and it does appear on regular
folders, just not on external drives. 
Any suggestions?  I'd love to be able to access my external files without having to turn on another computer!

I take it these devices worked on an older computer? Can they connect to another Windows 7 PC?
It could be a case of not having up to date drivers for these devices, even though the computer is new (it does happen): http://windows.microsoft.com/en-us/windows/update-driver-hardware-isnt-working-properly#update-driver-hardware-isnt-working-properly=windows-7
I notice the drive in question is formatted using FAT32. You may have to go to disk management, and assign a drive letter to it manually: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/i-want-to-acess-my-fat32-usb-drive/cd9d000c-82bf-4fe0-b590-f7597c46cc9e
If those don't work, and if you're comfortable using the command prompt, you can try running the takeown command on the drives in question. In this case, try opening a command prompt by typing cmd into the search bar, right click and choose Run as administrator, then follow the steps:

Then, type

My netbook has been running slowly for a while now, but at first I figured that it just wasn't made to be used as a primary computer. However, about 2 weeks ago, I realized that when I plugged in my external hard drive or flash drive, all folders were actually links to a system folder on my computer. Similarly, when I tried to upload photos from my memory card, it said there were no new photos. I had been using Symantec but when it wasn't finding anything, I downloaded Avast, which keeps finding random viruses but can't seem to find or get rid of all of them. I'm not sure if the virus or multiple viruses are on my computer or on the external drives, but nothing is working right. Plus I don't know much about computers. Thank you in advance for your help!!!

...but my CD-ROM drive works fine and my DVD drive can access CD-ROMs.
Here's my system:
-HP Pavillion 8755C 800MHz, 128MB RAM, running Windows ME
-Std floppy disk controller
-LG CD-RW CED-80838
-Samsung DVD-ROM SD-612

The problem started happening after my power supply blew and I had it replaced. The message I get is "Please insert a disk into drive a:" (e: for the DVD). I've checked all the suggested things on the HP support site:
- device manager looks good
- uninstalled all 3 devices in device manager, all 3 reinstalled with the same config after restart.
- Secondary Master, Secondary Slave, Primary Slave look ok
- cables look good - the stuff above wouldn't show up otherwise would it?

The only thing that looks different to me is that the drive letters have changed from m: & n: to d: & e: for the CD-RW & DVD drives. Any thoughts appreciated!


A:Unable to access floppy and DVD-ROM drives

Welcome to TSG!

If your DVD will read CD's but not recognize DVD disks, then the optics are hosed for the DVD playback. A DVD Drive typically has 2 sets of optics or optics that rotate. If the DVD read optics are bad, that is what you'll get.

As for the floppy...odds are that it's gone too!

If the Power Supply went out, it may have spiked and damaged the drives. Just hope that the motherboard isn't bad.

If the system is still under warranty, have HP replace both drives due to the power supply spike. If replacements are done and still having issues, then it would be the Motherboard that got taken out!

Good Luck!

This all started when I was unable to reach my NAS drive (DNS-323) from my laptop. ("The network location cannot be found.")
Trying from other computers was successful...so I know the problem is related to just my laptop.

I told AVAST to skip the file (for now) and I terminated the MalwareBytes scan.

What is the best sequence to get this file cleaned up?

I have a bunch of old hard drives laying around, and I finally got a USB enclosure so that I could get any old useful data off of them or re-purpose them. Some of them work exactly as expected, I plug them in, they connect, and a new Local Disk appears that I can click into. For several others though, the disk connects and is visible in the "Disk Management" utility but I can't do anything to it. All the options in Disk Management are greyed out, so I can't assign a drive letter or even format it. The only option that isn't greyed out is "Convert to Dynamic Drive", and when I tried it out of curiosity to see if it might make the other options available, it failed.

I find it hard to believe that these drives are completely useless and inaccessible. Is there some kind of trick or method that I'm missing? I've tried googling this problem, but it hasn't really gotten me anywhere.

Hi I'm having a helluva time with getting my Lenovo Y510P to recognize any USB flash drives or external HD. Laptop is virtually new. Came with Win 8 but I installed Windows 7 Pro 64 Service Pack 1. Immediately downloaded and installed all Windows updates. From Lenovo I installed all of the latest drivers and updates, including BIOS, Genesys USB mass storage device, Intel chipset driver and Intel rapid storage technology.
Laptop works great except for this issue.
I can see the flash drive in device manager but nothing in Computer folder. Same goes for Disk Management... no flash drive appears. I have no virtual drives installed so currently no Daemon Tools or similar.
When I plug the drive into any of the 3 USB ports (2 are 3.0, 1 is 2.0) the laptop makes the typical sound that you've connected something. These flash drives and external HD work fine in my other 3 computers here at home (2 laptops and 1 desktop). Some run Win 7... the other Win 8.1.
I tried going to Device Manager and uninstalling all USB controllers and hubs (including drivers), then restarting. My OS reinstalled everything (as soon as I plugged in my mouse and/or flash drive, if I recall correctly), but same issue persists.
I also ran DriveCleanup (claims to be "command app that helps to remove orphaned entries of various drives from the device tree of your system"). Same issue persists.

A:Solved: Unable to access XP network drives from XP PC

Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.

Hold the Windows key and press R, then type CMD to open a command prompt.

In the command prompt window that opens, type type the following commands:

PING each remote computer by IP address, and if successful, PING by name. Open a command prompt as described above and type.

PING <ip address>
PING <computer name>

<ip address> - is the x.x.x.x IP address
<computer name> - is the computer name

A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.

Note: You can obtain the IP address and computer name of a computer by opening a command prompt (DOS window) and typing IPCONFIG /ALL. This should work for any Windows version. The IPCONFIG /ALL display will provide a wealth of useful information for debugging your network connection.

Hey there,

I've had this persistent problem since the beginning of January. Every time I try to open files/folders in, say, my documents, in shared folders, etc. my computer freezes and doesn't bounce back. I've let it sit for almost two hours to see if it'd work itself out, but it never does. This correlates with my Firefox browser freezing during random intervals and causing my entire system to lock up. I recall installing Adobe Photoshop CS3 around the same time this started happening, but I'm not sure if it's something that could cause this kind of reaction. I also have the addon "ljlogin" installed on Firefox, but thus far, I haven't found any discussions to imply that ljlogin could be detrimental to my system. I've tried uninstalling and reinstalling firefox with all of the necessary updates. That made a difference for about two weeks, but now it's acting up again. It's also really hard to uninstall/reinstall things because the system locks up.

It's really tough not being able to access my files, but I can browse on Google Chrome without any issue (Unless I try to upload files from my PC). Any help would be greatly appreciated.

Hi Guys.

Hope everyone is having a great new year so far.

After formatting and installing a fresh Windows 8 Enterprise I am still unable to access any shared drives or folders on external devices via our domain authenticated network. Any drive/folder located on the internal drive ( it's partitioned into 3, C$, D$ and E$) are accessible from any other computer on our network, but all external devices be it Administrator access (//computer/F$, G$, et.al.) or via shares (//computer/My Videos (this folder is located on a 2TB Western Digital HD assigned DISK1, F$) are access denied to permissions.

These external drives/folders/shares have but one permission assigned to the drive, folders and files (domain/username) as full ownership and privileges, the same as on the internal drive, partitions, folders and drives.

Since this is a dual-boot system, I can simply reboot into Windows 7 Professional and every drive, folder, file and share becomes accessible via any computer on our domain as long as I'm either authenticated on that computer as domain/username or access said drives/files/shares using my domain credentials that are the ownership/permissions of all my drives, both internal and external.

So something in Windows 8 is blocking all network shares to external drives with permission errors.

I've changed Group Policies, Administrator Rights, shared whole drives, etc., all to no avail.

Does anyone here have a reason why Windows 8 policies block external drive access and h... Read more

One evening I attempted to install windows 8. After the installation it repeatedly booted back into the windows installation. After removing the install disk, it booted into windows 7 normally. I decided to install a clean copy of windows 7 and that's when the problem appeared. The windows insall will not allow me access to ANY hard drive shown. Says unable to find windows partition or something like that. I've tried reformatting all the drives and same message always comes up. I cannot re-install Windows 7?
Any suggestions would be greatly appreciated.

A:Unable to access Hard Drives in Windows 7 installation

It MIGHT be because Windows 8 installed as a GPT Partition...

But, Windows 7 and Vista can only see a GPT Partition as a non-booting data drive, unless using an UEFI BIOS.

Which MIGHT be why your Windows installation 'cannot see' an INSTALLABLE drive.

I would suggest Booting from a LINUX Bootable CD or USB Stick and reformat the Hard Drive to MBR,
i.e. delete the partition and recreate it as MBR and format to NTFS

Then reinstall Windows 7...

Hope this was helpful

Although in the My Computer window I found the icon for the flash drive to which I had downloaded the freeware program.....

Missing were the icons for both external drives and the icon for a second flash drive, all of which were operative earlier in the day.

I would be most grateful for any assistance you might provide me.

I am using external 1 TB HDD which probably is affected by virus and is not- accessible. Whenever plugged in to my laptop, system does not respond properly and also prevents shut-down.
Is there any way I can retrieve my files on external HDD. If not, how to format the drive?

When I connect my external hard drive to a laptop, it has a clicking noise where there are 2 each time, and it happens 11 times. It doesn't show up in My Computer, so I have no option to explore it and cannot do anything which requires referring to it by a drive number, like a disk check.

However, it is recognized as being connected because the USB option to safely remove it comes up.

In disk manager when I try to initialize it in order to be able to assign a drive number, I get a CRC error, and sometimes it won't even let me click on Initialize

Due to my old laptop recently being broken, this extra HDD is the only place where my files are stored so I really don't want to do anything which will lose them, and am desperate to get it back as there are years of photos on there.
What can I do?!

I have read some other threads regarding this same issue, some sound quite similar.
External Hard Drive - connected by USB port 2.0
Windows recognises that USB Mass Storage Device Drive has been connected - however it does not show in My Computer as a drive.
Computer Management - Disk Management does not list it as an available drive.
Device Manager lists it as a drive - and device is working properly.

How do I get access to the drive to recover of anything from it using any data recovery software?

A:Unable to access External HardDrive

It is not available, as it is not in a file system available to your operating system (it is raw or another system). Using Disk Management you can Format in NTFS and the the system will allot it a drive letter and make it available

System recognizes that I have a USB 2.0 external. When I power it on the little red light will flicker and then nothing. Formally, both with Windows XP & Win98, the light would flicker for a while and then you would get a pop-up window asking what you wanted to do with this info. This does not happen now with my new internal HD with newly installed versions (dual-boot) of XP & 7. I can tell the system to safely remove this external HD & it does. I get the beep when it recognizes it when turned on and when it gets removed. Have not found the answer yet as to how to show the data as previously done. It does not show up in MY COMPUTER either but does appear in Devices & Printers in Win 7. No apparent problems there nor in Device Manager. What gives?????? Anybody??? THANX!!! This is an ACOM Data 80GB USB 2.0 connected via a USB cable.

Bad enclosure. Very common with Externals. Means power regulation is failing/has failed. Just replace the enclosure. You can get nice slim ones from newegg for a decent price. Simple to assemble.

Yesterday, for no apparent reason, my external hard drive became suddenly not accessible.

When I click on the Local Disk F: icon in MY Computer I get an error message that reads:

F:\ is not accessible
The file or directory is corrupted and unreadable

My external hard drive is a Western Digital Essential Portable 320GB USB drive.
My OS is Windows XP w/ SP3.

I have used this drive for the last 2 1/2 years with no problems. I have had it plugged into a USB port on the back of my PC. I tried a side port and another USB cord with no luck.

I have tried using PC Tools Disk Suite to see if I could use it's repair function but it does not seem to be able to access it either and only sees my C: drive.

There is nothing absolutely essential on this drive, being filled mostly with my music collection and some movies, but it would take a great many hours to restore everything.

Is there a way to recover access to this device? If I can't, is it possible to reformat the drive and start over? Or is the whole thing just toast?

Any help would be greatly appreciated.

Problem: A portable hard drive seems to have been infected by some kind of malware. Folders appeared as shortcuts and were inaccessible. Trend Micro's Housecall found a worm but upon fixing it the folders have now 'disappeared' even though the drive still has space being used up as if they are still there.

I think I know the source of the problem: recently at school I had to use my portable drive for an important school project because nothing else was available, so I had to plug it in to numerous computers the students use. The kids often go on random gaming/movie/you-get-the-idea websites on these school computers.

Recently, when I plugged my Samsung S2 Portable external hard drive into my Compaq 615 Notebook running Windows 7 Home Premium 32bit and used Windows Explorer I could play an mp3 file stored there but I couldn't open any folders.

I got a message that, according to Google searching, seems to be common when one's drive has become infected with some kind of virus, worm or trojan: "Windows cannot find 'E:\RECYCLER\bcd8f464.exe'. Make sure you typed the name correctly, and then try again."

When Exploring the portable drive all the folder icons appeared as though they were shortcuts in that they featured an arrow image on them. This included $RECYCLE.BIN.

I have ran both Avast! and Malwarebytes which both reported no problems despite the portable drive folders remaining inaccessable.

Both have the advance sharing features set with no password sharing. Attached to the HTPC via usb is an external 2TB drive with media on it. I want to access that drive and all the folders from the home pc over the wifi network.

On my home pc I can see the folders that are shared on the HTPC. When I click on one I get an error saying I do not have permission to access the file. All the folders and the external drive are set to be shared on the home network and read/write by Everyone.

Hi, I installed a bitlocker on an external HDD via a Surface laptop with Windows 10 Pro. I have the Id key and recovery code of the bitlocker. However, I cannot access the HDD anymore after encryption was completed although my laptop does recognise that
the external HDD is plugged in. The following message appears: "The bitlocker encryption of this station is not compatible with your Windows version. Try opening the station with a newer Windows version".
This does not make sense because I have the updated Windows 10 Pro.  
When i get to the security via the control panel, there is only teh option to unlock drive (which is clearly not working), but not the option to enter a password or to de-install bitlocker.
What can I do to retrieve the data on the external hard drive?
I appreciate your help but I am not very good at dealing with IT \

I have a Buffalo Drive Station 1TB External Hard Drive. I've used it for three months w/o having any issues w/ it until yesterday. As usual, I plugged it in my pc and waited for it to automatically run. (my os is an xp pro servicepk3 btw) While i was waiting, my I.E. froze, and i got the blue screen of death. After restarting my computer, I tried plugging it in again and it will read, but i just can't access it. It shows up on the bottom right corner where i could 'safely remove it' and when i open up 'my computer' the icon appears as a normal drive (it usually has its specific icon and name) but i can't click in to it. When i attempt to click it, my computer goes in to a long lag. I tried everything i could possibly think of, unplugging the cables, reinstalling the driver, using different ports, etc. Any other ideas?

My external hard-drive (seagate) stopped working, when I plug it in I get this message:
"You need to format the disk in drive F: before you can use it. Do you want to format it?".

For a long time now whenever I tried safely unplugging it I got the message that it is still being used even though no program was open. so eventually I've been unplungling it not in a safe mode for quite a while.

Needless to say it hold valuable information, I've tried using Recuva and testdisk (which I read on in other posts of the same problem in this forum) without success, it does not manage to access the folders that were on the disk .

I'd appreciate any help with recovering the files,

Hi. I use a 1tb external hard drive to store music, photos and movies. I use it on my Imac, also on my Asus e-book. I see that the external hard drive is partitioned into two. How or why I don't know. What I do know is that the first part is now full, and I cant see the second part when plugged into the USB on either computer. Could anyone help me by suggesting how I can access the second 500gig? Id appreciate answers in plain English, I really dont understand more than the basics, and the clearer ans simpler the answers the more I will learn, and thanks to all those about to read this !

Back-up all your data on the first partition.​
Right click on "My computer" and click "manage".This should take you to the computer management screen.​
Look at the left, you should see an option that says "Disk Management"; Click on it.​
You should be able to see all the disc partitions, find your External HDD partitions.​
Right-Click on the 2nd partition and delete it.​
After that right click on your first partition and select the option to "Extend Partition"​
​If you are confused, or need confirmation for anything please don't hesitate to ask.​

After installing a windows update I can't access my external hard drive. When I plug in the USB cord the laptop recognizes it and installs the drivers. However, when I go to My Computer all I see pertaining to the ExHDD is "Removable Disk (D: )" and "Removable Disk (E: )" instead of the old "Maxtor One Touch (_: )" like it did before. Clicking on both D: and E: results in "Please insert a disk into Removable Disk (D/E: )". I've tried doing a system restore back to a week ago and then to 2 weeks before that with no luck. I've also uninstalled all the USB drivers in device manager, restarted, and plugged in the ExHDD again. After plugging it back in the drivers were reinstalled and it nothing else happened. The ExHDD doesn't make any abnormal sounds, it lights up properly too so I don't think it's damaged at all.

It's filled with data so I want to avoid having to erase any of it. Any suggestions on what I should do?

Hello. I wanted to easily move my files from a hard drive from a computer I was using for Windows 7 pro to another. I basically removed the windows 7 pro hard drive in that computer and placed it in a Sata Dock connected to another computer but when I tried to access the user folder, it said I do not have permission to access the folder. In windows XP this was never a problem. Any suggestions how to bypass this security blocking access to my files so I can move them onto the other computer's hard drive. I didn't use any password on this computer.. I ended up putting the hard drive back in it's original computer and moved files to another hard drive. But it would have been easier to do it the other way around. I would appreciate any help.

Not sure what else could be preventing me from using this as it was before now. The reason I'm still still trying is that the Windows remote desktop worked far better than any other remote desktop solution.

Any help appreciated.

I am presuming that you have a static IP Address configured on the MAC? If not, you will need one.

The first thing I would do would be to download the latest version of the MS Remote Desktop and do a re-install of it:
Download Microsoft Remote Desktop Connection Client for Mac 2.1.1 from Official Microsoft Download Centre

Have you tried using Logmein? I've found it to be very stable.

Hi all!

I have been running two 3.5" hard drives internally in my stationary computer for some time now, one is 2TB and the other is 4TB. As I have recently switched to a laptop setup I wanted to bring these two drives with me for storage, so I took out the 4TB and put it in an external case. The drive was used a single partition GPT in order to gain access to all 4TB.

Now however, I am able to access it when connected through USB, but some files are not accessible. I cannot open them, and when I try to copy them I get Error 0x80070057: parameter is invalid. Remaining files on the drive work fine. I am trying to access the external drive on a Win10 Home x64 laptop (Lenovo Y700)

I did some digging, and in disk management in windows the drive shows up just fine as being one volume, 3,63TB, however in MiniTool PartitionWizard only 2TB of the drive show up as being a volume, and the remaining 2TB show up as being unallocated. I assume that this is somehow connected to the GPT format of the drive.

Does anyone have any clues as to what might fix this and get me access to my files? PartitionWizard has an option to extend the volume into the unallocated space, but this seems exceedingly dumb to try as I'll probably lose the files for good then.

For some reason about 75% of the time when I have an external hard drive plugged in to either my laptop or desktop computer (both running Windows XP Professional SP3) it won?t let me safely remove the drive when I?m done with it; the error message I get on both computers when trying to remove the drive using ?Safely Remove Hardware? is: The device ?Generic volume? cannot be stopped because a program is still accessing it. Except no programs are accessing it, not even Explorer. I?ll then have to shut the entire computer off in order to remove the drive since nothing else seems to work.

I did try the steps listed at this site but I still got the same ?Generic volume? error message after closing the two threads that were accessing the external drive and Process Explorer didn?t show anything at all as accessing it once I had closed the threads that were there. If it helps, the two threads were apparently the same thing at the same location: F:\System Volume Information\EfaData\SYMEFA.DB

I googled that file/file path but didn?t really find anything that related to my problem. So could anyone here help me out? Like I said, this happens on both my laptop and my desktop computers which aren?t connected to each other in any way so in addition to wondering why I?m getting this message to begin with I?m wondering why I?m getting it on both machines.
Any info or advice would be much appreciated.

A:Unable to "safely remove" external hard drives on either of my computers

Program Accessing it message is usually a residual effect of a files cache still running in memory. Windows should have cleared it but in many cases it does not go away. If your right click the Safely Remove Icon in the System Tray, and then Remove the drive, if you get that message, close it and hit it again. 9 times out of 10 it will let you Safely Remove it then. If not, wait a few minutes and try it again, if it refuses, then just unplug it. The only danger is that it may not get recognized if the drive was using a file at the time, but this is rare.
