USB Storage devices on Windows 7 x64 - WORKING FIX

Q: USB Storage devices on Windows 7 x64 - WORKING FIX

Ok. Now i'm already on 32-bit version of Windows 7 and so far happy with that. The only hurting loss is RAM, but all other things seem to be perfect.

But still, i remember (just a couple of weeks ago!) myself having pain with my external HDDs, portable player and other devices. So here i am, posting TEMPORARY fix for this.

From an elevated command prompt (right click on the command prompt shortcut, run as administrator):
1) Type "bcdedit /set truncatememory 0x80000000" (no quotes)
2) Reboot
3) Go to control panel -> System and Security -> view amount of RAM and processor speed.
- It should report 4GB (2GB available)

To undo this, open an elevated command prompt again:
1) Type "bcdedit /deletevalue truncatememory" (no quotes)
2) Reboot
3) Go to control panel -> System and Security -> view amount of RAM and processor speed.
- It should report 4GB

BE SURE TO UNDO "deletevalue" THIS FIX AFTER THIS ISSUE IS RESOLVED so you get all your memory back.

this fix was suggested at social.technet.microsoft.com, and it doesn't have any negative circumstances for your OS (at least, so far no reports), the only thing is that you loose half of RAM

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.)

my work laptop is running windows 7, when I try to install my external HDD via the usb ports I get the pop up that windows is installing the drivers and that it ready to be used. However in my computer the drive is not listed, when I enable the drive from device manager the drive pops up but it inaccessible, then eventually disappears from my computer. I'm not the administrator on the laptop, but my user account had admin rights. For the 30 seconds the drive stays enabled the properties/security tab says a its unable to display owner.

This is also a problem on thumb drives and SD cards, the machine just can't recognize any external HDD's

any help would be awesome

Up until recently, it was a simple, straightforward procedure to
transfer files to and from a memory stick or digital camera via any USB
port on my desktop. The stick or camera appear in Windows Explorer under Control Panel/Portable Media Device. Since installing SP2, however, when I attempt to access their files, nothing shows up, and when I attempt to move or copy files to them, a STOP symbol is displayed. Other USB devices work normally, and both the memory stick and camera work normally on my laptop and appear as removable disks, as they did on my previous desktop.

Following advice so far: fully updated system (including drivers), virus and spyware checked, disabled suspicious-looking services--which has not resulted in any other problem. What next?

After I upgraded from WIN98 to XP SP#2 and then SP#3 I can?t get any of my USB connected flash storage drives to work on my Dell Opitplex GX1p PC. I have tried my San Disk Cruser Micro 1GB, and my Cruser Mini 1GB, and tried my Western Digital (WD) Passport external 160GB hard drive, and nothing works. These external drives all work on other computers in my home.

My old Dell Opitplex PC is currently running XP Home SP#3, has four USB ports, two are legacy (V1.0 -1.1) and two are new Belkin USB 2.0 PCI ports. All of these ports will recognize both Cruser flash drives as "new hardware", and will recognize my WD Passport external 160GB hard drive, but even though I have upgraded to SP#3 the drivers for this devices do not load.

Under "My Computer", Device Manager, Properties I can see:

Universal Bus Serial Controllers, but the USB Mass Storage Device does not show up as "installed" as it does in one of my other home PCs (Gateway XP Pro). The Dell Opitplex GX1p Device Manager with XP Home does show other entries, such as 4 versions of USB Root Hub, 2 versions of NEC PCI to USB Host Controller, one version of Standard Enhanced PCI to USB Host Controller, and new hard ware installed successfully this week, shows up as Belkin USB 2 High Speed Host Controller, & USB 2 Root Hub Device.

What would cause all USB peripherals to work, with the exception of Mass Storage Devices? No Blackberry, No Ipod, no thumb drives.

It just says USB device not recognized.

A:Solved: USB mass storage devices not working

Is this on your Windows 98 computer? Windows 98, out of the box, won't use those devices like 2000/XP and newer because it does not ship with generic drivers (2000/XP do).

Check this out for a generic Mass Storage Device W98 driver. The site claims it will work with "most" USB devices.

I have been looking for a solution to my USB flash drives and external HDs for a while now. (I'm still on Windows XP Pro SP3, BTW.) The system stopped installing new drives a few months ago, even though I can take them to other machines and they will install fine. I always get that damned Hardware Wizard, which invariably "cannot find the driver". I have tried uninstalling the USB Root Hubs and letting Windows reinstall them on reboot, I have tried replacing usbstor.sys from the Windows install disk (I've even tried a delete of usbstor.pnf, usbstor.inf, and infcache.1 and letting Windows rebuild those files). I even spent Saturday afternoon reinstalling Windows in the hope that some misbehaving file would get overwritten and work. All that did was make Windows no longer recognize the USB drives it had before, so I'm worse off now for trying that.

Hoping someone here has been through this problem and has some ideas I haven't tried yet.

Some while back I installed Acronis True Image Home 2012 on my Win7 64 bit PC. It is a backup solution that would have satisfied my backup requirements at the time. I immediately found a problem with the fact that it failed to recognise my network drive as a backup location. After days of communications with their support dept. and a couple of sessions of remote support they realised that the software was not happy about "empty" disk drives. I have a built in multi-port card reader and also have card readers built into the monitor. They show as disk drives in "My Computer" even when there are no cards in the slots. The option in Windows to "hide empty drives" didn't cure the problem.

They eventually sent me a patch that cured the network drive recognition problem but left me with the problem that my PC no longer recognises any USB mass storage device or any memory card plugged into either of the card readers. I didn't realise I had this new problem for some time as I don't use USB disk drives. It's not just USB attached devices that are not recognised, it also won't recognise firewire disks either. I have tried un-installing the Acronis software but it doesn't remove the errant driver(s).

I've tried removing the devices and rebooting to force an update and I've tried scanning for new drivers without success. The PC tells me I have the latest drivers installed.

The title is basically all you need to know. I have tried everying, but I am up for suggestions.

A:All USB storage devices CRASH windows

Can you insert a USB device without Windows crashing? Or is it durring boot/restart? I was getting a BSOD on bootup from a flash drive. I was able to insert the drive once Windows was up and running, then in device manager I expanded 'Portable Devices' and disabled the flash drive there.

This didnt disable the storage but the portable drivers Windows loads because it thinks my flash drive is a poratable/music device type.

Depending on your storage devices you may need a driver update. I was also getting errors (not crashes) and had to update the Intel Storage Manager. Some info on your system might help us to better determine the problem and solution.

Hi Guys, i have a quick question regarding USB storage devices.
i'm running Windows XP Sp2

when i plug in my flash drive, iPod or card reader (with a sony memory stick in it) to my usb ports , Windows detects them and the "safely remove hardware" icon shows up in the bottom right toolbar. however, i cant access my USB devices from My Computer, the drives don't show up.

i read on some other post that you have to manually go into Control Panel->Administriative Tools ->Computer Management, to assign a specific drive to the device. However, after i tried that, the devices still dont show up in My Computer.

I'm not sure how to fix this, any help is welcome!
all my other USB devices (such as my keyboard and mouse and printer) work fine

A:Windows not recognizing my USB Storage devices

This may seem obvious and i don't mean to be patronizing but have you tried a different USB port? I have never heard of this problem. Also when you plug in your Ipod does it appear on iTunes? Also does it not prompt you when you plug in your devices open, run, view pictures etc.? Have you disabled that, if so enable it.

Hello, I have a problem with Windows 7 Build 7100. I am running a Fujitsu Amilo Li 1818 laptop. The installation went fine, I had to download a driver for the WLAN card, but everything else works perfectly. However, when I connect a USB thumb drive, or an external USB HD, I can't access it. Windows 7 recognises the device, installs a driver, and the device is visible in Control Panel > Hardware and Sound > Devices and Printers. It doesn't show up in Computer > Devices with Removable Storage. In Device Manager, the USB HD shows up under Disk drives and it says "The device is working properly" and the driver is up to date. However, when the USB HD is connected, it also creates an "Unknown device" entry under other devices in the Device Manager. This part says "The drivers for this device are not installed (Code 28), and clicking on Update Driver doesn't work ("Windows was unable to install your Unknown Device"). I have installed the Vista chipset drivers from the Fujitsu website. Any ideas how I can fix this? Why does Device Manager recognise the USB HD but also create an "Unknown Device" entry?

A:Windows 7 won't recognize USB mass-storage devices

I've got it fixed now, after reading this: http://forum.freecompromo.com/viewtopic.php?t=181 The solution: step 1! Go into C:\ and create a folder called usbdriver step 2! Go into C:\WINDOWS\INF and copy the whole contents step 3! COPY ALL THAT INTO C:\usbdriver step 4! THEN when your asked to look for the driver! and vista cannot find it POINT IT TO THAT FOLDER C:\USBDRIVER and click ok. Looks like it was a bug from Vista.

I have a Dell XPS 8000 with a 4 in 1 card reader. I also have a DVD and a Blu Ray drive installed in the computer.

But in the descriptions in Computer, I get this:

BD-RE Drive (G SD/mini-MMS/RS

I have even moved the two drives off of the SATA ports built into the motherboard to a Startech SATA III PCI card, but this behavior continues. I have even deleted the 4 drives in device manager and had windows reinstall them. I have also unassigned and reassigned drive letters to the card readers. Nothing I have done fixes the situation completely.

The only progress I have made is that after moving the drives to the PCI card ports, I can put a disc into either drive and it will read it, and the description will change and drop the card reader description. But the other drive will keep the wrong drive description.

What can I do to fix this?

hey guys, im new here (signed up solely to ask this question cuz it looks like a pretty cool site) and i need some advice

so i built my own computer out of purchased parts about a year ago but its been having freezing problems until a few months ago (bad hard drive lol!). i havent noticed this problem til recently (due to the constant efforts to diagnose the freezing/crashing) but my computer seems to eject any usb mass storage device when i try to say.... copy files into or out of whatever drive is connected, whether its a flash drive or my phone's sd card (which is connected via usb).

For example: this happened today - i tried to drag an .avi file out of a SanDisk cruzer and the windows dialog box pops up to tell me that it has begun copying. after 5 minutes, it is still 'Calculating...' the ETA and i notice that the explorer window that displays the content of the drive has been turned into that washed-out, unresponsive state. Running Windows 7, if i try to close the window, i get the choice to either close the program, wait for it to respond, or some other thing.

this happens if i plug any usb drive into any usb port (front or back) on my computer. Wow that was a lot to write. well if anyone has come across this sort of problem before or can help point me in the right direction,

This board has the AMD crossfire chipset. If I hook up any USB storage device Windows Vista Ultimate x64 instantly hard locks. I then have to power off the PSU and wait 60 seconds before I can turn the computer back on. The power switch will be completely unresponsive until I do this.

If I have the USB storage device on and then boot up it will hard lock before I can reach the login screen. I can repeat this behavior.

I can also cause 5 to 10 minute delays during the Vista install by having a USB storage device attached. The slow downs occur during the initial menus.

Has anyone else seen this problem? This behavior does not occur under Windows XP. It has to be a problem between Vista and something on this motherboard. I also noticed AMD/ATI has never bothered to update the chipset drivers. I find it very hard to believe they are perfect and don't need any fixes.

We currently got some problems with our Windows 7 clients. Every notebook we install requires exactly 5 minutes to recognize some USB 2.0 storage devices. Every USB 3.0 storage device works perfectly and is immediately detected. I've tried many different
USB 2.0 devices with the result that some are working and some need exactly 5 minutes until the device gets recognized. For example the Corsair Flash Voyager is slow and the San Disk Cruzer Blade is fast.

If such a corrupt USB device is plugged in while starting the system, Windows stops booting after the "Starting Windows" dialog. Only when I unplug this device Windows continue with booting.
I know there is something wrong with our Windows Setup, so I use a new one for the following notebooks. But we've already installed some notebooks with that Setup and need to fix them now. Installing the system with the new Setup fixes the problem.
I've already tried to upgrade the BIOS, remove drivers from the Device Manager, install the latest driver and perform an system-upgrade but nothing fixed the problem.

Can you help me to solve this problem?

Hi I Just made a new computer and every thing is working great. Jut one thing that is a little Irritating. When I click on my computer and you see Devices with Removable Storage. I see 31/2 floppy (A), DVD- Ram Drive (D), Removable Disk (F), Removable Disk (G), Removable Disk (H), Removable Disk (I), Removable Disk (J). My old computer would show just the floppy and the DVD but the rest would not show until you put in the USB stick or the SD card in then it would show up.

This way it is easier to identify witch one you have put in. Other wise It it is looking like this Removable Disk (M) then if your not looking good you will have to click on all of them.

Is there a way to do this?

on my computer, it is the same thing. Even is there is no media in the the Media Reader Slots, they still show up, How ever with a media card inserted it shows a capacity bar much the same as the hard drives, so you can identify which media slot is occupied from that.

I think the Local Disk Q is from my USB which I disconnected when I powered off the system. Now whenever I click it, I get this

Anyone know how/if I can fix this?

A:2 Extra Storage Devices?

I believe the E and Q drives are part of your main drive. Partitions of the physical drive the C drive is on.
The H drive is a USB stick.

Not sure why the Q drive is not accessible other then it is a small partition and it is not formatted. But then it shouldn't show up.
The E drive is a normal system partition but it is usually at the front of the drive and normally does not have a drive letter assigned to it. Win 7 creates this area to store the BOOT loader files and some other system files.

Alright, so here's my problem:
My Dell Inspiron E1505 laptop hasn't had any problems in the past as far as USB storage is concerned. But recently it's developed problems being able to read these devices. It's only storage devices like flash drives and my external HD - my mp3 player and my cell phone can still hook up to it without problems. Also, new "Local Disks" are showing up.. There's my original "C:" HD, my backup "D:" HD that came with the laptop, and now there's also a "F:" and "G:" that show up- I looked on PC Inspector to see what they were and it appeared they are Dell setup partitions called "DellUtility" and "DellRestore".

Anyways, when I plug in a USB storage device, it doesn't bring up the "what do you want me to do with this thing?" autoplay that XP normally does when you put something into it. When I go to My Computer and click on the removable drives ( usually H: or I: ), it says "The disk in drive _ is not formatted.

my usb sticks have all stopped working recently ive tried them in different usb ports and all have the same error. im guessing this is more to do with windows and not my sticks because i have several of them and they all cant have broken at the same time.

anyway the message i get when i try to access the memory stick is

"the disk in drive "drive letter" is not formatted do you want to format it now?"

i clicked yes one time but it said windows couldnt complete the format for some reason.

anyone know whats going on?

Try one of the non-working usb sticks in another computer to confirm it works fine first. Make sure that other computer you'll try it to has an up-to-date antivirus, in case this could be malware related.

Go in the device manager : start => run => devmgmt.msc. Any warning message there about your usb devices ? Unplug all the usb devices you could have attached (use a ps/2 keyboard and mouse), right-click => uninstall all the usb controllers in the device manager. Restart windows and they'll get redetected.

I'm having issues with my computer recognizing any sort of mass storage device. Most of the time when a problem comes up I have no problem figuring it out unless it's a laptop hardware issue - that's a nightmare.

Anyway I've tried to plug in a USB Jump Drive (128 MB) and an External USB Hard Drive (80 GB) and both devices are recognized but Win XP Pro can't find drivers for them and they should already have drivers in Windows according to the manufacturer. Heck I use the jump drive at work on a number of different systems and it works just fine. I suspect maybe a bios setting is off or perhaps another USB device is causing interference for mass storage devices. I had one case where I tried to play a game and my keyboard was causing it to crash.

Iíve tried all of the simple troubleshooting I could think of. I thought giving it a file path under disk management might work but it isnít there. Iíve tried reinstalling usb drivers, using a different cable, resetting the kindle.
Oddly enough, my roommate has the exact same computer as me and we both got our computers reimaged at the same time and his kindle has the same problem.
I found a post from a user with a very similar problem:


She even has the same computer as I do. But hers was resolved by updating an unrelated driver (acronis) and Iíve searched my computer and donít see anything like that.

Any help is greatly appreciated.

Hi... I read the sticky but I wasn't sure on how to get all of that information, so I just copied the hardware stuff from the system info log. I'm sorry, I don't really know a whole bunch about hardware, so if didn't get the log edited right, I'm REALLY sorry, cuz it's long = (

This is a rebuilt desktop with only a 20 gig hard drive...the guy I bought it from did a quick switch a roo on me after I had looked at it. This is my problem. I have an external 80 gig hard drive that I use for my data files so I can leave room on the internal for programs. It is a Seagate 80 gig USB I also use a USB mouse, keyboard, and webcam. These 4 things are always connected to the system. And as long as I don't try to plug in another USB storage device, everything works fine, but if I try to plug in a flash drive or an external DVD burner, Windows won't recognize them, I get a message saying the device has malfunctioned....but if I reboot, leaving in the flash drive along with everything else, Windows will see the new device(s) but not the external HD, but it doesn't work the other way. I can't remove the flash drive and reboot and have windows see the ext HD.. It's such a pain to get Win to see the ext HD again..I have to.put it in different USB ports and reboot again and again until it finally connects. Is there anything I can do about this? Is there some kind of limit on storage devices you can have hooked up at one time? I use the fla... Read more

A:How can I make my USB storage devices ALL work?

Is your USB drive self-powered?
I wonder if this is just a problem with the available power in your USB ports.
Does the drive work if you disconnect the camera, for instance?
You may need a powered USB hub.

Hi all,
Since 2 weeks I have a strange USB storage driver issue.
Notice that it works perfectly before (as usual before not work :-))
This issue occurs with all my USB storages devices (Disk, Key) from a lot of different manufacturer (transcend, Kingston,...).

The symptom ==> see USB1, USB2 and USB3.jpg uploaded files
DriverMax not show an USB driver update.

sfc /scannow = no integrity violation

I have Windows 7 Pro 64 bits on a lenovo W510.

A new idea will be appreciate.

I have a machine on which xp is installed at the momen, it has some big files and all datat is scattered here and there, So, no chance I can format it completely, though I installed the xp-repair install which fixes the system32 errors. It fixed the PC freezing issue. But, two problems are still nagging me.
First, my dvd-ram drive is not working, the icon appears as dvd-ram, but, the moment I insert any disc the dvd ram logo changes from this to this and then it even stops taking eject command.
Second, I am not able to access my flash drive. Its says this.

And the thing is in safe mode my dvd-ram and flash drive both are working fine. Please help

How to Avoid Problems with USB Storage Devices
Updated May 2, 2010​If you're having USB drive problems, also see: Troubleshooting Guide Windows Won't Recognize Your USB Hard Drive

Do's and dont's to avoid problems with USB Storage Devices

Don't: ?Surprise? Windows by unexpectedly removing your USB storage device
=> USB storage devices are "hot pluggable". This means you can plug them in any time but does not mean you can simply unplug and/or power them off anytime!
=> !!Never, ever!! unplug a USB storage device before first either stopping the device using Safely Remove Hardware icon or shutting down Windows
=> Unplugging unexpectedly may corrupt your storage device and result in partial or total data loss!!
The Safely Remove Hardware icon
You'll find it among the notification area icons along the bottom right of your Windows Desktop

=> Notification Area icons appear on the right side of the Windows Task Bar
=> The Task Bar normally appears along the very bottom of your screen

The Safely Remove Hardware application informs Windows you intend to remove a device. This gives Windows an opportunity to prepare for the removal by taking steps such as halting data transfers to the device and unloading device drivers. Removing hardware from a running system without using the Safely Remove Hardware application, is referred to as ?surprise removal?

Hi all,

I've recently purchased a new PC running Windows 7 Home Premium. Everything is running like a dream except I have five devices with removable storage showing in My Computer. All I have attached is a WD External Hard Drive which I have assigned to E: changing my CD drive to K:

Is there any particular reason why these 5 additional unknown devices have appeared and can they be safely removed?

Many thanks in advance

Yeah, sorry about the title, I tried to make it as informative as possible.

I'm asking for help. I've searched around the net for ages to try to find answers to this issue, but I can't find anything that matches my problem exactly.

My computer has issues with usb storage drivers I think. All usb stick thingys don't work. And they do work on every other computer I've tested them on... which is probably around six or so. Whenever I plug them in, it comes up with that very unhelpful message that says that "USB not recognised", and when I check the device manager, it comes up with Unknown Device.

Also, when I plug in an MP3 player, they are only read half of the time. The other half, they do the same rubbish that occurrs with my USB things...

My printer and keyboard both work fine, so I know it isn't a problem with my hardware. Well, maybe it could be a problem with my PSU, but it is a 550W, and I'm sure that my components aren't draining that much power.

Finally, my 7-in-1 card reader isn't recognised by vista most of the time. When it is finally recognised and the drives show up in My Computer, but when I put an SD card in or something, nothing happens.

I'm running Windows Vista Ultimate, which was upgraded from a buggy version of Home Basic Lite edition. And, if I can't get this fixed, I'll format my computer, but I don't really want to resort to that.

If you need anymore informati... Read more

A friend of mine asked me to fix her Toshiba Satellite A105 laptop. "What's wrong with it?" I asked. "It's broken," she said.

So I boot it up into XP Media Center SP2 without any problems and plug in the 2GB Kingston DataTraveler that has all my Windows System utils. I'm met with an error.

USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.Click to expand...

Well, that's not a very helpful. I click the message, and a window pops up showing the USB Root Hub item, where it says that the fourth USB slot is an "Unknown Device." Curiously, there are a total of 8 listed USB slots when there are only four physical female ports on the laptop. I open up the Device Manager, uninstall all drivers under the USB Controller section, and restart XP.

When it loads back up, it has the same problem. Now, I start testing the different ports and experience some curious results. No matter which port I plug in the pen drive first, the same message pops up. However, if I quickly take it out and plug it in somewhere else, Windows occasionally "finds" the DataTraveler 2.0, but still says that there was an error installing the device and won't let me access it via My Computer. One more interesting thing: Device Manager occasionally identifies the existence of a "Generic volume" named ... Read more

Could anyone please tell me why when i use my USB memory stick it seems to take an absolute age to copy.It seems to spend ages calculating time needed then is so slow.

Never was like this XP, seemed so fast.

Anyone any ideas

A:removable storage devices and vista

If you are using a new VISTA machine it should work as fast as your XP machine. If you 'upgraded' to VISTA then possibly you have a Driver issue, i.e. your computer no longer knows it's using USB 2.0 and thinks it can only go USB 1.0 speeds. If that is the case you might be seeing a message saying "USB 2.0 device on USB 1.0 port".

I recently started seeing a problem on one of my laptops where all USB storage devices would mount but when I try to access them through explorer I get a warning saying the location is not accessible and access is denied.

The system can see the usb device, derive the name and file system type of the volume be it a pendrive or a kindle but I cannot access the files.

All of these devices work without issue on my other Windows 7 laptop.

I get this regardless of being logged in with a user has administrative permissions or standard user permissions.

The laptop is a DELL Latitude XT2 running Windows 7 Ultimate fully patched.

Any help much appreciated.


A:Access Denied on all USB Storage Devices


Install the latest chipset driver from: http://www.dell.com/support/drivers/us/en/19/DriversHome/NeedProductSelection?fkey=Drivers_PS

If the issue still persists, then try following the below mentioned steps:

1. Right click the drive.
2. Select Properties.
3. Press the Sharing Tab.
4. Select Advanced Sharing.
5. Put a check on "share this folder".
6. Press Permissions now that it is clickable because you put a check on share this folder box.
7. Under "Group or Usernames" there should be a default option of everyone. If it does not show this for you, press add and type Everyone.
8. Check all 3 boxes under Allow [full control, change read].

Hope this helps.

Vista runs the "new hardware found" wizard when I connect my External WD hard drive and my Sony DSLR Digital Camera. It is looking of a driver. Both of the "mass storage units" work fine on my XP boxes. WD or Sony both say no driver is needed except the one windows should already have. All my usb hubs have been checked out and have the latest updates and my Vista is completely updated. The "Details " say it's looking for a PNP driver. My Sandisk memory stick however works okay with the Vista system.

Any ideas how to fix this? This is a new computer and runs Vista Home Premium 32.

A:Mass Storage devices and Vista

The usual RX is to go into Device Manager, View, Hidden Devices, and remove ALL the stuff under USB Controllers, then reboot. See if that helps the situation.
