Correcting I/O Device Error on Externa
“I have an external hard disk of 500 GB of Western Digital, can be seen in the administration of disks and Windows Explorer, but when I try to access the subfolders, I get a message that says “
I can not make the request for an error device e / s ” I do not know what to do to resolve this problem, if there is any repair tool? The information on the disk is very important to me and I have to recover the disk.”
What is an I/O device error?
In most cases, it comes with the message “Request cannot be made due to an I/O device error”.
This error usually occurs because Windows is trying to use a transfer mode that the hardware device cannot use or there are disk errors.
According to these two main reasons, we can now take these two measures: 1. from the system command line; 2. change the transfer mode of the unit in the properties of the IDE channel.
Two solutions for correcting I/O device error on external and internal disk/ USB/SD card
Step 1. Recover data from your device with I/O device error
If you have important data on your storage device, it is best to try to recover your files first with the free EaseUS data recovery software before correcting the error, so avoid data loss by following these steps:
Connect your external device to the computer, download and run the EaseUS data recovery software on your PC, select the device (it is recognized as a disk drive) and click the “Scan” button.
The software will perform a quick scan to look for data on your device. Once completed, a deep scan will start automatically to look for more data.
After the deep scan, you can preview those files you want, then mark them and click “Recover” to save them in a safe place on your computer.
Step 2. Correct I/O device error via system command line or change drive transfer mode
Correct I/O device error via system command line
Press the key combination Windows + X to open the menu and select the command prompt option (Admin).
In the command prompt window, type chkdsk E: /f /r /x. Here E should be replaced with its drive letter.
This option will run the chkdsk command prompt to check and repair errors on external and internal hard disk/USB/SD card.
The “/ f” element asks CHKDSK to correct any errors it finds; “/ R” locates bad sectors on the drive and retrieves readable information; “/ X” forces the drive to dismount before the process starts.
Correct I/O device error by changing drive transfer mode to IDE channel properties
Press Windows + X to open the menu and select Device Manager.
Expand the IDE ATA/ATAPI controllers, it will list the different IDE ATA/ATAPI channels for the equipment.
3. Right-click the channel where the drive is connected, and then click Properties. Normally, this channel is a secondary IDE channel.
4. In advanced settings, select PIO Only in the Transfer Mode box for the device the unit represents. Normally, this is device 0. Then click OK and exit all windows.
Check if there is still an I/O device error on your device.
