USB device not recognized. Device descriptor request faile

Q: USB device not recognized. Device descriptor request faile

Hello everyone,
i hope you can help me sorting out this issue that is causing me a hard headache at the moment.

I've bought this new Lenovo Z50-70 laptop with windows 8.1 preinstalled on it. Fresh new.

I'm trying to connect via usb a guitar audio interface (Line6 POD HD500) so i installed the drivers via the .exe setup file i downloaded from Line6's site.
The device worked fine on my previous HP pavilion with windows 7.

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.
I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.
I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.
I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

Edit: the software tool from which i can update drivers and other things for my guitar interface says that no drivers are installed on pc.... even if i try to re-install them.

Any help appreciated

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.)

I am having the same exact problem as you, Cattanius. I couldn't get it to connect to my computer over 2 years ago and then just decided to try it the other day. I didn't expect anything to show up in device manager because I thought the usb port was fubar, but then I see the same message you got and all of the sudden there's hope! I hope.

I have a flash drive that I previously used in public computer lab (where many viruses linger) the other day to do my work. As I got home, the flash drive isn't working anymore, saying "USB Device not Recognized". I also noticed that it really took me a while to finally, safely remove it from the computer lab's PC. So I actually wonder if it actually removed my flash drive properly.

On Device Manager, it says "Unknown USB Device (Device Descriptor Request Failed)".
On the Properties, the device status says "Windows has stopped this device because it has reported problems. (Code 43) -- A request for the USB device descriptor failed."

My flash drive is a Kingston Flash Drive DataTraveler (DT100) 16GB, and my PC is running on Windows 8.1.

Things I have tried:
- Shut down my PC, unplugged power and removed battery, waited for a while, booted my PC and try plugging in again.
- On Device Manager, uninstalled it and scanned for hardware changes, it still returns as "Unknown USB Device".
- On Device Manager, I clicked "Update Driver Software..." and it returns me a message saying "The best driver software for your device is already installed".
- Unfortunately, when I visited Kingston's website to check if there is driver for this specific flash drive, there isn't any... "There are no downloads or drivers available for this product".
- Used Windows 8's Troubleshooting tool. It only detected my problem, but was un... Read more

A:USB not recognized (Device Descriptor Request Failed)

if you have tried on other systems using different OS then the error is normally because of issues with the item not the PC , it might be 'confused' or have corrupted data or be faulty.

If you have the data still stored elsewhere...then you may be able to reset the flash drive and see if it recognises it then.

I'm not sure if there is a reset switch anywhere on that stick.

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

A:Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.

Hi onyx,
This error means a device driver notified the operating system that the device failed. This circumstance can occur if the device hardware fails or if the device driver fails.
Have you tried to update the device driver for test?
Please follow this guide trying t resolve this issue:

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.
The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.
The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.
Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.
I've tried:
uninstalling the device and rebooting
installing the latest updated chipset drivers from the dell website
windows updates
pretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

Any other ideas?

A:XPS 15 9550 Bluetooth stopped working (Unknown USB device - device descriptor request failed)

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.
After rebooting, BT and my mouse is now working again.
Something seems to be really flaky here, but hopefully this will help others with the same issue.

Hello, ok so after recently doing a clean install of windows 10(please don't get me started on that mess). my system has been plagued by random usb drops. it's where everything connected via USB suddenly disconnects then reconnects out of the blue. well I was using a Rosewill Transenclosure RX200R-APU-25B USB 3.0 dual 2.5 hard drive enclosure and transferring files from one drive to another (connected via USB) when one of these drops occurred. Now whenever I plug in my hard drive enclosure in a windows warning pops up and says "the USB drive that was just connected Malfunctioned and could not be installed" and in system manager it says "Unknown USB device (device descriptor request failed)". I know it's not the hard drives because I can remove them and use another connection and they work fine, all files intact. It's just now my hard drive enclosure won't recognize. This also happened to a "Loot crate exclusive Game of Thrones stark sigil 4GB USB stick I plugged in and turned into a windows 10 install drive. When I plugged it into use it after the windows media creator said it was done the USB stick was raw and unformatable. Please help. Microsoft keeps telling me it's a hardware issue even though it happened on two different systems. both operating windows 10 never any issue with windows 7 or 8.1

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

Fresh install of Windows 10 and the last driver I need to sort out is the above.

I believe it is my powered USB 3 hub to which I plug in my keyboard and mouse. Technically it is working but I don't like seeing yellow triangles on devices.

So are there any fixes?

A:Unknown USB Device (device descriptor request failed)

If it's a generic USB 2.0 Powered Hub then technically there's should be no drivers needed by Windows, if it's a USB 3.0 Hub then I'm unsure (since I don't own any USB 3.0 Hubs).

Might be a Windows bug, basically Windows can't find the description information to display the Hub's name in the Device Manager example: Generic USB Hub, Root Hub Device, etc....

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

Let me start out by saying that I've googled the shit out of this problem, tried several things, and nothing worked.

I have a D-Link USB 2.0 Hub that I got about a week ago. It's been working awesome up until recently. It's a plug and play device, however windows is failing to recognize it, and thus making everything I have plugged into it unusable.

In the 'Device Status' box it says:

Windows has stopped this device because it has reported problems.
(Code 43)A request for the USB device descriptor failed.

And in the 'Events' tab, there's a few listed, I'm not sure if they are much help:

Hi all,

(Unknown USB Device - A request for the USB device descriptor failed)

Massive problem I have encountered since buying a new laptop pre-installed with Windows 8.1

I have 3 external USB storage devices - 1x Corsair "Slider" 64GB, 1x HiTachi Touro 750GB, & 1x HiTachi 4TB external drive. ALL drives are coming up with the same error message and are not being recognized by Windows 8.1

The strange thing is, I also have another 2 PCs - one with Win7 and one with WinXP and the drives work without issue.

I've spent the last 4 days scouring the net looking for answers, and thus I am here hoping someone can shed some light as to why ALL of these drives do not work on this new laptop pre-installed with Windows 8.1?

Even stranger still is I have other thumb drives, a cheap Transcend 32GB (which is USB3.0) and a few cheapo (USB2.0) drives of various sizes by Strontium, Lexar and so on which work perfectly.

But the one that has me o.O is an expensive 64GB thumb drive called the Mach Extreme which also works perfectly with this laptop???

So all up 2x HiTachi drives & 1x Corsair thumb drive are not working and its driving me bonkers!

If no drives worked at all, then I would be seeking the manufacturer for maybe a faulty component. Dodgy USB ports, or maybe a motherboard problem. But having a handfull of drives, of various makes, sizes and both USB3.0 - 2.0 fully working leaves me scratching the old chrome dome as to what could be the issue

A:A request for the USB device descriptor failed. (error43)

You can mark this thread as SOLVED!

Okay here's the fix that worked for me, maybe it will work for you.

I've always updated drivers, WinXP, Win7 and so on, the same way - download the driver, go into device manager and select browse, then point windows to the downloaded driver to update the necessary files. Its always worked that way for me for as long as I can remember.

Not so it appears with windows 8 - for some strang reason.

For me I had to update to the latest Intel Chipset Drivers, but instead of the tried and trusted methos above, you simply hit the setup.exe and let windows 8 do its thing. Believe it or not, but this fixed the issue.

Yes I had already updatd to the latest Intel Chipset Drivers using the device manager method, and yes windows "did" update ...someting??? But the USB devices were still showing the Unknown USB Device error. But using the setup.exe fixed the everything and all my USB devices are now working perfectly with Windows 8.

How, why, who knows, but I hope this works for others with the same problem.

Hello Ladies & Gents.

I would like to ask for your assistance on this slightly annoying problem.

I have 1 pair of Razer Megalodon USB headphones, on the start up of Windows 8.1 these headphones are not detected correctly. The only proof I have of this is in the device manager displays:

Universal Serial Bus Controllers -
Unknown USB Device (Device Descriptor Request Failed).

(Please see attached screenshots)

Once the device is disconnected and reconnected device manager then displays:

Universal Serial Bus Controllers -
USB Composite Device

The device then shows in "Audio inputs and outputs"

A:Razer Megalodon - (Device Descriptor Request Failed)

Razer is well known for BSOD drivers and problems, otherwise. (And taking very old drivers, changing nothing at all, giving it a new date and then claiming "Compatible!" with new OS.)

Perhaps give a shot with uninstalling their software, rebooting, the re-installing.

Make sure using the latest.

When all is said and done, you might just have to live with it.

Can't hurt to make sure chipset drivers are up to date. If Intel chipset, search their driver site for "Inf"

Greetings folks

I have a problem that bugs me for years, I never intentionally solved it, sometimes those errors disappears and all USB ports work fine, sometimes they do not. So anyone can help me please, it would be great.

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

CPU: Intel Core i7 3770
Motherboard: AsROCK H77 Pro4/MVP
Windows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10.
Here is what they look like:

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

Thank you

Most of the threads on this error are old, (2015) so I am starting a new one. I only notice it when I happen to be in the device manager. I have no problems with any of my connected USB devices (that I have observed).

I have tried uninstalling it, and rescanning and it pops up again, so apparently it is something that is connected. Without disconnecting All of my USB devices one at a time (which I am wont to do, as it is not bothering me, other than that it is there!) It has been there for quite a while, so apparently is not anything new being connected.

Is there no way to identify WHAT is connected to this port, or even what port it is?

BTW, it only shows up in the USB Controller section, no matching errors in any of the devices themselves!

I have an external Bluray/DVD drive (ODP1201=S3-B) that works perfectly on Windows 7 but is not recognised by my new laptop which has Windows 8.1 64 bit. Can anybody explain why this is and what I do to get pass it, or is this a problem with Windows 8.1?

The device is listed in Win 7 as "hp bd rom bc 5501h", and the driver is 6.1.7601.17514

I have now tried various USB devices; I have connected a USB 2.0 External Hard Drive and a USB 2.0 Canon Camera both of which work OK, I have also connected a Seagate 1T external drive which is USB 3.0 an that was OK as well (the ports are all USB 3.0 on the laptop hence the reference to the which USB type)

The error message is as follows: "USB Device Not Recognised", When I go in to Device Manager I find two USB error listings, Unknown USB Devise (Device Descriptor Request failed) & Unknown USB Devise (Port Reset Failed)

I have been advised that this error can arise when a drive doesn't receive enough power from the system. The device does have two USB connectors, I have tried using both of them. The power cable going to the powered USB on the laptop and the data going to the adjacent USB (there are a pair of USB sockets on either side of the laptop, the right hand side having the only powered socket).

A:Unknown USB Device - A request for the USB device descript

I'm too of opinion that it's a power issue. Laptops are not known to have much power thru USB ports, not even some desktops for that matter. Possible solutions: If that laptop has USB3 port you can try it in there, it gives more power and is compatible with USB2. Another one is to ad external power to the drive. One of the USB connectors on the twin cable has only two connection tabs and is for extra power to device. That one can be connected to universal USB charger for phones etc. That's how I solved a problem with a HDD in external enclosure.

I have an USB device (an embedded system that I am developing) and associated driver.
It has one interface with two endpoints (BULK IN and BULK OUT) and control endpoint.
When I connect that USB device to PC, then device driver is getting associated with device and I am able to use the device.

Now I have updated USB device descriptor to have one more interface (all other information like VID, PID are same and also existing interface is not altered). Now it has: one control endpoint, one interface with BULK IN and BULK OUT and another interface
with BULK IN endpoint.

When I connect this USB device with modified device descriptor, USB driver is not getting associated and giving me error code: 10 (0xA).

Device driver software is from 3rd party.

Now I am not sure if error is thrown by windows kernel or device software.
Please help me in debugging this.

Any log files/events that can be enabled when device is connected and how driver is loaded, what checks are performed by kernel to load the driver etc (I believe it only looks at VID and PID).

FYI: Same setup works on Linux environment (looks liek linux just ignores this additional interface added)

I have two WD "My Book" 3.0 USB drives.  Previously, they both worked fine.  Now one of the two drives is getting a device descriptor request failed message.  The other drive is fine.  I have tried different 3.0 inputs on the system both in back and on top in the front.  Any ideas on why the same drive isn't working?  I have tried both on other systems and they work fine.  The other systems I have tried them on are WIN7 and WIN 8.1.

A:usb 3.0 drives getting device descriptor failed error

Hi there slovey  Have you, by any chance tried with another USB cable? I wouldn't make sense to change things as the device works on other systems but it wouldn't hurt to use the other My Book's cable with the problematic one just to rule this out as a potential cause. I would also check this thread and see if the offered solutions there help.  Keeping your OS, BIOS and drivers up to date is also an important part of the troubleshooting process. I'd also check if there's a new update specifically for the driver responsible for the communication between the drive and the system. Post back if you need more info! Captain_WD.

It's recognized in device manager as "Unknown device". But I've not connected anything to pc. Also all of my usb ports are working at 1.1 speed. When I try to connect any device, I get the message "that it could work faster, if i connect it to hi-speed usb port".

Any suggestions?

A:USB device not recognized - but there is no usb device connected

It could be two unrelated issues.
1. You could have a device that needs a driver.
2. Some motherboards use a mixture of 1.1 and 2.0 ports, so that's the reason for the message.

You could check to see if you can get a hardware id for the device, from the device manager.

I have a Dell notebook, with what I believe is a USB 1.1 port on it. I recently bought a Microsoft wireless notebook optical mouse. There is no installation CD with it, you are just supposed to plug it in and it should work. Well when I do that, I get an error comes up saying USB device not recognized. When I look at the properties it says "no drivers are installed for this device", and I have the device usage as enabled. I've tried updating the driver and it says I have the most recent updates installed. It comes up as an unknown device as well.

Other things like my printer work in this USB port, so I don't think the port itself is defective. I also plugged the mouse into another computer and it works with no problems. I am running on XP with SP2 installed.

The product specs say it should work on USB 1.1 or 2.0, so I don't think that is the problem either. Any ideas? I've gone through all of the troubleshooting with no luck.

This has become a great annoyance to me.

Whenever I have my keyboard and mouse plugged into my computer (the mouse uses a USB port on the KB (it's a G-15)) I keep getting messages of "USB Device Not Recognized", however, the mouse and keyboard work perfectly fine. It's not really a problem, it's not restricting me, but it is extremely annoying.

Any solution to this problem?

Note: I recently re-installed Windows (literally about an hour ago), it did not do this beforehand.
Note 2: I have tried to restart the computer.

A:"USB Device Not Recognized" but the device is working fine.

A search turned up some easy things.

Does this happen coming out of sleep or hibernate?
Does this happen in another USB port
I think you said you rebooted - no change. If you haven't rebooted, give that a go.

Last one: right click on the device in Device Manager and select "Scan for update". Could be the USB, mouse or kb - scan all asscociated devices

That's all I have,

I have a PC which is having a lot of trouble recognizing a USB data acquisition device. Starting from a situation where the PC *does* recognize the device, here is the basic pattern:

1. PC shows device in Device Manager under "Data Acquisition Devices".

2. If the PC is power-cycled via the power plug itself, the device is no longer recognized under Device Manager ("Unknown Device").

3. If the PC is power-cycled via Start Menu --> Turn Off, same results as above, no longer recognized.

4. If the PC is power-cycled via Start Menu --> Restart, no problems, device recognized.

When the device is not recognized, unplugging and replugging the USB cable makes no difference to the situation. In order to correct the issue, I disable and then enable via Device Manager (which also involves a restart).

This pattern is extremely repeatable.

I am working with WinXP SP2, Pentium, 2.8 GHz, 504 MB RAM.

This PC was returned from a customer site - the PC and USB device are used in a machine my company manufactures. Apparently this issue just started happening one day. We want not only to correct the issue, but in fact to understand the root cause and ensure it will not happen again in the future.

Any suggestions would be greatly appreciated - thanks!

A:USB Device Recognized / Not Recognized based on shut-down method

You could try reinstalling the usb drivers.
JohnWill has fix that is worth a try

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

Ok, today when I turn on my computer in the morning all of a sudden it took ages to boot, when it booted my D: drive was not showing in MY COMPUTER.

Computer wasvery unresponsive, so I checked the Administrative events and I saw like a hundred of this message:

A request to this device has been cancelled.
Device: \Device\RaidPort0
Model: WDC WD1002FAEX-007BA0
Firmware Version:05.0
Serial Number: WD-WMAUR0614125
Port: 1

I had 3 Sata drives in my system, this one (Wester Digital Caviar Black 1000gb) had my sample libraries and it had just like 19gb of free space.

When I disconnected the drive computer booted normaly.
I dismounted the drive and put it on a usb docking station and it was not recognized and computer was slow again..

I see the BIOS and the HDD shows there.. (strange)

I can't believe my HDD died on me cause I just have like 4 months with him..

What are your advices over this issue??

Thanks a lot people

A:a request to this de device has been cancelled

Try burning this iso to a cd/dvd: WD Support / Downloads / SATA & SAS / WD VelociRaptor

Boot from the optical drive and see what WD's diagnostics program has to say about the drive. (WD's diagnostics program is the same for most of their products, so don't worry if the product on the d/l page doesn't match yours.)

If the drive seems to be only marginally healthy you may want to make sure you backup all data from it before running the tests.

Hello everyone..
Yesterday my laptop pushed a new Win 10 update, and all went fine, or at least I think so.
But today I see that my Sony WALKMAN - which I used with no problem until now, can't be recognized anymore.

Basically it just shows as (E or Usb Drive E: but when I click it it says "Please insert a disk into E:/" like there is nothing there.

Now the interesting part is.. if I go to Device Manager I see it and clicking on properties etc t says it's working fine.

But if I go to Disk Management, the Drive shows as 14 gb of unallocated space and it's greyed out.

However, if I put it on my brother's laptop, it works perfectly and it can be opened, music moved into it etc - it shows as Healthy - Primary Partition in Disk Management. So it doesn't seem broken...

It's the same on each of the 4 usb ports btw. But, other usb devices (2 phones, 1 tablet) don't have any issue and are detected.

What could have caused this? I tried the basic Disable/Enable in Device Manager and also Uninstall Driver.. It doesn't do anything, it appears back when I replug it in.

No change in Safe Mode and no change after sfc /scannow

If anyone has any idea I'd be happy to try anything to fix this..


A:USB device not recognized on my laptop but recognized in other pcs/lap

This problem is being reported by many forum members with many different USB devices. It seems that Windows 10 Anniversary is having problems properly recognizing certain USB drives and devices. So far, no one has come up with a clear fix for this issue but it sounds like it is clearly related to the Anniversary update. For the record, I did a clean install and have not had any issues but most of the people reporting this problem make reference to updating to Anniversary.

I am looking for help. I have a Toshiba Satellite A105-s4164 Window XP SP 2 Media Center Edition purchased in August. Just last night I noticed that my (D) Drive which is my DVD-RAM Drive as it reads now is not working correctly. I can play DVD's but it does not recognize CD-R/RW CD's nor actual Audio CD (retail). I seem to think that at an earlier time the Drive use to read CD-R/RW drive. ??? Could it just be the setting? The DVD-RAM is a Matshita DVD-RAM UJ-841S.

I have gone through the forum and tried out all the suggestions I could find. Still the problem exist.

When attempting to copy files to a CD I recieve this message: The request could not be performed because of an I/O device error.

After going through all of the suggestions I could find I decided to do a full recovery (factory) and the problem is still there.

I have gone through Record Now! and Window Media Player using an Audio CD (retail) and I recieve the following message disk empty or drive busy. When I open the file nothing is there.

Please help. This is driving me bonkers.

Thanks in advance.

I've created a new thread for your issue here.

I've been currently using a 600gb SATA HDD for my OS etc and everything else. I decided to put in my other SATA 320gb HDD as I am going to need more space (Recording with my hd capture card takes up alot of space!). I put it into the HDD bay, plugged both the SATA cable and power cable into it. I turned on my PC and it read it and said it was set to go. I went into Computer Management to set it up and a window popped up saying I needed to initialize Disk 1 being the drive, so I clicked ok. It freezes for a second and then a small box pops up saying "The request could not be performed because of an I/O device error." Please help, I am very smart with computers for the main concept however HDDs are actually one of the only things I'm not very experienced with. Thanks guys! I appreciate any support. I am using Windows 7 64 bit OS in case that matters.

A:NEW HDD - The request could not be performed because of an I/O device error.

OK, first of all, we have no idea what you are working on. Post your exact system specs ie make and model of mb, cpu, amount of ram, etc. If this is a big box system, then post the make and model.

Have you rechecked/reseated both pw and data connections for the drive?

Have you tried a different sata cable and or a different sata port on the mb?

I recently did a clean install of W7 Professional. I installed W7 first on the SSD. Once the operating system was running I then proceeded to add the internal HDD (500G Seagate). Unfortunately the system just does not seem to recognise the HDD.

Device Manager:
In Device Manager->Disk Drives:
Drive 1: W7 sits on my 64G SSD and has the location 1 (1).
Drive 2: The 2nd drive is an internal 500G HD that has the location 0 (0). The drop down box of Device Usage shows: "Use this device (enable)"

Disk Management
I went to the Disk Management but:
a) only the Disk 1 is showing
b) it is does not appear to be seeing the 2nd disk

Computer Management
I went into Computer Management and tried to enable the Disk. Unfortunately it has come up with "The request could ot be performed because of an I/O device error"

The HD is an intertnal HD with Sata connectors.

1) I changed the Sata ports but still no difference
2) Windows says the drivers have loaded correctly and the device can be used
3) I ran the Trouble Shooter but no issues were found.
4)The same issues as above are occurring. Please see images below:


Low Level Format
Additionally I have tried to run a low level format. The software picked up both drive but when I went to format the drive i get the error below (see attachment)
