SOURCE: the hard disk drive is not working

Two of the most common causes of I/O (Input/Output) device errors are driver based. Typically, either the device's driver is not enabled or it is out of date.

The driver component has an important function, as it acts as a motor like force that propels USB/plug-and-play hardware into a driving action within the computer.

It is the connecting communicating link signaling the CPU to a desired movement.

And while not all I/O device error solutions are simplistic, as a good starting point, you can try troubleshooting using a few basic steps, and you might not need to attempt anything else.

Access "Control Panel" from the Start menu and then choose "Performance and Maintenance."

Click "System" and then go to the Hardware tab and click on "Device Manager."

Find the device that is registering an error by expanding the nodes of the appropriate category.

If the device has a red "X" on the icon next to its description, the hardware is disabled; proceed to Step 4 to enable it. Otherwise, go to Step 5.

Go to the General tab and click "Enable Device" found under the Device Status section; then press "OK." (Note: You may have to follow prompts, as indicated through an enabling device wizard.

If you do, continue to click "Next" and follow the prompts until the process has completed.) Test the hardware.

If an error is shown, proceed to Step 5.

Go to the General tab and click "Troubleshoot" found under the Device Status section then press "OK." Follow the prompts to solve the issue.

If an error is still shown, proceed to Step 6.

Go to the Driver tab and click "Update Driver." Follow the prompts until the process has completed and then test the hardware.

The hardware that you are trying to access is damaged or failing.

The device drivers for the hardware are faulty or incompatible.

There is a connection problem such as a bad cable

for internal hard drives

Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a

secure dust free connections and are not faulty or just replace them they could be faulty if its a flat 40pin ide

this will be the first to fail

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty

or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error

for usb drives

click start control panel administration tools computer management device manager scroll through all of your devices

if you see a yellow question or exclamation mark ? ! or a red X you will need to update the drivers for this device right click select update driver/reinstall driver

if you can see your usb device but its not working scroll to Ports(Com&Ltd) right click to update driver

if you computer came with a motherboard disk the drivers could be on it

hope this helps

Hi , I have problem in my hard disk ,, I con't open my files :''( this masg is " this request can't be performed because of an i/o device error " help me plz :(

I/O device errors are rarely repairable without buying new hardware. Test the drive with manufacturer's diagnostic software. Toshiba do not have any such software but you can use SeaTools for Windows:

Choose the Long/Extended test for thorough testing of the drive.

When i inserted an external drive to my pc, then i want to access to this external drive, it says the request could not be performed due to io device error.

io error means that the "Input/Output" is not working. This could be due of different reasons. Try the following:
1. try it on another computer if it works, it's something with your computer. Could be hardware (e.g. loose connected cable or driver) 2. try another USB cable, if it works, its due of the USB cable (or the cable has loose contact)

I saw the message while copying even a single file from my external USB HD i-e "the request cannot be performed because of device I/O" and "digital delyed right failed" simultaneously...

Is the error occurring when reading "from" the W.D. drive,
or is the error occurring when writing "to" your internal drive?

> digital delyed right failed

Is that the exact spelling of the error-message?

I/O device error

Hmm? Your drive may be corrupted which makes it unuseable. I hate to admit your files may be lost at this point also. In order to reuse the unit, repartion and format the unit. I hope this helps.
