Vista: USB not recognized, storage devices only

Q: Vista: USB not recognized, storage devices only

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 information, I would be happy to provide it.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


Woke up this morning to find my HP stuck in a boot up mode with a message about it being unable to find any storage devices...tried safe mode (F8) but no luck...would not boot into safe mode...can not get into BIOS...F2, F10, F11 all not working...only thing that had a glimmer of hope was inserting the HP recovery disc (1 of 3) I made then restarting...seemed to work a bit as the screen changed and it said "loading windows files" but then nothing...subsequent reboots with same disc went unrecognized...even tried booting using Hiren's Boot CD but it seems like the machine is not recognizing ANY bootable drive...HDD or CD/DVD.


A:Unable to boot into any mode...storage devices not recognized

Most likely a power supply failure, that's a non-servicable part except by the manufacturer, so it's one you replace. [can hold a charge and possibly KILL you if opened up]

Any PC repair shop near you can verify that the PSU is croaked in a minute, with a PSU tester which you can buy for $20ish.

Rosewill RTK-PST Digital LCD Power Supply Tester - Newegg.com

PC is acting like it doesn't have the juice to run the parts, just so much more likely PSU dead, eliminate that before moving on, hopefully it didn't damage anything else.

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.

I have many USB flash drives and 2 USB hard drives. None are working with Vista Home Premium 64 bit. When I plug them in it says "Device Driver software not successfully installed" In device manager, the icon for my USB device has a little yellow exclamation next to it and says "A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)" How can I get this to work? I know it is not a hardware problem, as I am dual booting with XP and it works fine in XP. Ive tried uninstalling it and re installing it, did not help. Please, help me get vista to overcome it's fear of USB mass storage devices!!

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 have a Samsung laptop and a few weeks ago some of my MP3 players stopped working with it while some continued working. Infact one stopped working and another one (the exact same type of MP3 player) continued working despite the fact that all of them worked on a different computer. I found that I needed to "recover corrupted Vista driver database" and located the problem to Microsoft KB934637. I then requested the Microsoft Hotfix for the x86 version (it's 32 bit). After a day or so microsoft sent me an e-mail with a link to the hotfix and temporary password. I installed the hotfix and (other than a couple of times when it wouldn't recognise a flash drive) my laptop has been fine since. I dread the day the driver database goes corrupted again.

Now my main machine, an Acer running Vista has what looks like the same problem. I have tried to use two different flash drives on the tower today but to no avail. In hardware profiles when I tried to search for a driver (which shouldn't be necessary with Vista as the flash drive is compatible with Vista) I get the following error "Windows encountered a problem installing the driver software for your device. Windows found driver software for your device but encountered an error while attempting to install it. USB Mass Storage Device. This device is not configured correctly (code 1)." However in this case the MP3 players I previously used with the tower are still working. It's just that I cannot ... Read more

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?

Until this problem started this week, I've not had problems accessing data from my USB thumb drive through the 4 USB ports on the front of my computer.

Now, when I plug a device in, I hear the indicator that i've plugged something new in I can see the devide in the Devices and Printers window but it isn't fully recognized... says troubleshooting is needed, though when i run the trouble shooter, nothing happens. This has happened with 3 different thumb drives and a usb cd burner.

When I go to access drives on the computer, I am unable to see the usb thumb drive.

To date, i have uninstalled the usb drivers and restarted and that didn't work.

If I try to restart with ANY usb drive in the front 4 ports, I get a blue error screen saying there is an unknown boot device, so I end up having to restore to my last restore point.

Any help would be much appreciated!!! THANK YOU in advance!

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?


A:[SOLVED] usb storage devices

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 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.

Open Disk Management and post a screen shot of that.

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?

A:Devices with Removable Storage

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.

The autoplay process does not even start, it seems like as the PC is attempting to access the device, it freezes.This is strange, since

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.

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. Do you want to format it now?" and I have tried formatting it since I don't have any valuable information on my flash drive but it still doesn't fix the problem.

I've tried looking up myself how to fix this problem but I'm only finding bits and pieces of information on similar problems but nothing has helped. I'm hoping someone here has an idea of what I might do because now I can't use... Read more

A:Solved: USB Ext Storage not recognized

Hi jaylin

Try this:

Plug the FLASH or EXT drive. You should hear the "turun" sound when an USB device is plugged in.
Right click My Computer and select MANAGE.
Got to the Storage section and click the DISK MANAGEMENT section. Wait on the right side to populate.
Check if your EXT drive or your flash drive is listed there.
IF so, check if it has a DRIVE LETTER assigned to it (Should be something like D:, E: or such)
IF it does not has a DRIVE LETTER assigned, right click it and select CHANGE DRIVE LETTERS AND PATHS.
If it has any drive letter assigned to it, change it to a letter form the end of the alphabet, say Y: X: or Z:
This is to ensure that you are assigning a letter that is available on the system.
After that, Say OK to everything and close the Computer Management window. Your FLASH or EXT drive should appear now on the MY COMPUTER window with it's new drive assinged.

Hope it helps !

I've posted this here before with no luck but I figured I'd try again.

Windows 7 is not allowing me to install USB Mass Storage Devices.

If I plug in my generic USB hard drive, I get the "Installing Device Drivers" balloon, and then it fails.

If I look at Device Manager it lists "Other Devices" and "USB2.0 Storage Device" with the yellow triangle icon next to it. If I manually choose drivers and have it look in \SYSTEM32, it says Windows found drivers for your device but an error occurred during installation. USB Mass Storage Device The System Cannot find the file specified.

Interesting notes: I have VMware Workstation installed. If VMs are running (XP or 7) THEY recognize the drive just fine. AND USB storage devices that I had ALREADY used on this system still work. It's only new ones that have this problem.

Dell support was completely useless. They first suggested reinstalling Windows... no thanks. Then they wanted to swap motherboards - not a hardware problem. So I appeal to the wizards here. Then *get this* they called me to say they would help me but since it is "advanced system troubleshooting" there is a fee - even though I am under warranty. To hell with them!

I did try deleting INFCACHE... no effect. Also played around with UpperFilters reg keys... no effect.



A:HELP! Win7 will not allow me to attach USB storage devices

It sounds like you already got to decent answers. You could try getting drivers from the maker of the hard drive to try to fix your problem, since drivers aren't being installed automatically. If it shows up in VMs then it might be something that requires a repair install.
Repair Install

I don't see why you shouldn't go ahead and get the new mobo, provided its actually new. Motherboard, like all hardware, can develop problems over time. So, if its a new motherboard, not a refurb, I'd get it just to get a free $200 piece of hardware.

When I try to access any removable storage device (DVD, pendrive, memory stick using a flash card reader) on my Windows Vista Business, I always get a "access is denied" message. And now all the removable devices listed on Windows have a red "not allowed" symbol (as you can see here: http://img477.imageshack.us/img477/8504/problemadc4.jpg )

I believe the problem started when Windows froze while the computer was reading a memory stick, so I had to reboot it using directly the power button. Before that, everything was working fine (and they're still working under Linux).

I have already tried to reinstall both the flash card reader and the dvd drive, and it didn't help. I did a chkdsk too. My guess is that it has something to do with the removable storage manager or something like that.

Although I am one of the many people who have not been able to activate Microsoft's Windows 10 upgrade icon and assistant, I am fairly confident that my W8.1 Tablet is OK for the new OS, except in one respect --- available storage. It only has a 32 GB SSD, most of which is taken up by Windows, leaving at present about 5 GB, whereas 16 GB free HDD space is required. I have been using a variety of strategies to reduce demands on the HD but so far without much success, in particular replacing desktop programs with portable programs on the integral Memory Card, using Cloud storage for files, and of course removing unnecessary programs / apps.

I have seen a brief 'rumour' that MS is working on ways to help owners of 'small devices' with restricted HD storage, Tablets and phones. Has anyone heard about this?

If I understand it right, once I have W10 on my Tablet my storage difficulties will be reduced as I will have greater ability to save and install everything including Store apps to different locations, such as a Memory Cards.

I welcome advice for those of us with 'small devices' who may be facing difficulties with getting W10 installed in the first place. For example, what are the pros / cons of the two methods: using update or using an ISO image?

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 ... Read more

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

What is this a fix for?

Hello all

Well this is a strange one.

Anytime I try to plug in a "new" (e.g. never plugged in to this computer before) USB Mass Storage device, device installation fails. When I click on the balloon that says device installation failed, it says "No driver found". If I manually choose a location to search drivers and choose \Windows\System32\Drivers, Device Manager chooses "USB Mass Storage Device" but says "could not install because there was an error". (Gee, thanks, so helpful )

I am getting this error with an old iPod Nano (1st gen!) but it will also happen with USB Memory Keys etc.

Any ideas?

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?

A:Removable Storage Devices not working

Read other 6 answers

Iíve been banging my head against the wall due to a kindle touch/windows 7 issue.
Last week I had my computer re-imaged and now when I plug in the kindle via usb it doesnít show up under removable storage devices.
It does make the noise that you hear when plugging in a usb device, and I can see it under device manager, but not disk management.
Iíve tried to uninstall then reinstall kindle software, but when itís reinstalling it crashes by computer every time. I get the BSOD.
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.

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.

I can't access the data on USB storage devices or camera cards. The USB ports work fine with keyboards and mice, and when I opened the "Safely remove hardware" window I noticed that cards and USB hardware are listed but the generic volumes have no drive letter in parentheses. Despite this I have a USB hard drive plugged in that does work, appearing as drive G:. None of them show up in the Storage section of the Computer Management tool.

Let me know if any additional information is needed.

For the record I'm running Windows XP Home on a laptop I purchased used, though this issue didn't develop until over a full year after I purchased it.

A:Cannot access data on storage devices.

Move the KB & Mice to the ports that seem to fail and try again.
If it's the same result, a USB HUB could have died. Also it might not be able to supply the power required for external USB storage.

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?

So I have this weird problem with my PC where any sort of removable storage or music device I connect to my PC through any USB port, shows up saying that it needs to be reformatted and then if I try to reformat it it says that it cant do it.

I have tried this with 2 flash drives that work on other computers and an Ipod that is perfectly fine. It says that the Ipod is corrupt or something and wont work on Windows.

Obviously there is something wrong with my PC, but I'm not sure where the problem is coming from. I already have a USB mouse and a USB cord for my keyboard that I leave plugged in permanently and they dont seem to be effected. It seems like anything that is showing up on my PC as a storage device or drive, automatically needs to be reformatted but I cant actually do it.

This is a real problem, I need to be able to move files on a flash drive for school and its currently not possible. thank you in advance for any advice.

hello i am running on a win XP system. i problem is that when i connect my memry stick to usb port it picks up the stick, but i believe it is picking it up incorrectly for example i am fairly sure my MP3 player is not supposrt to go under the catgory of 'disk drives' and should go at the buttom with 'universal serial bus controllers'.

this is hapeening with all usb storage devices, my mouse and keyboard seem to be uneffected by this though.

another thing i would also like to point out is that on 'my computer' the HDD(C) drive is showing with a wireless icon, this also baffles me.

please dont mention the start bar, i find it 20X easier when i have lots of windows open and lots of msn contacts spamming me.

i thank you in advance for taking the time to read this.
