5 Efficient Fixes for io device error on sd card, usb flash drive, external hard drive

#1 Use the usb socket from the back side of your desktop.

It often happens to a desktop or old laptops. If your computer is a laptop, you may directly jump to the second solution.

The usb1.1 usb2.0 usb3.0 conficts may bring the io device error, device is not accessible, especially when the front usb port is usb1.1 while the usb flash drive, sd card reader or external hdd is usb2.0 and above.

usb2.0 port

Change another usb port(the ones at the back side of your machine) when there are four usb socket that you need to try one by one. Here is a story from a user telling he tried the usb at the right side of the back, it did not work until he tried the usb port that is close to the internet connection socket.

"Now most desktop computers have several usb ports, usually two in front of the chassis and four in the back, two of the four in the back near the mouse keyboard interface and two near the network card, when I use the front two USB ports the removable hard drive does not respond, the USB port near the mouse keyboard interface can read out but when copying some files prompted "I / O device error, cannot run this request". O device error, cannot run this request". Finally, the USB port near the network card has no problem at all."

If the front usb socket is a USB1.1 while some usb flash drive or external disk has USB 2.0, the error io device error would pop up due to the weak power supply from a usb1.1 port.

If it still reports the same error message io device error after all the back four usb sockets, here are some possible causes.

1: The motherboard is old and the USB driver is not installed. (right click my computer or THIS PC = > properties = > Device Manager - = > check whether there is an exclamation mark! If so, the driver is not installed. ) uninstall the drivePhoto 1You may uninstall the device(steps shown in photo 1), and then reinsert it, and then come back to the device manager, click Action tab on the top menu, and then click "Scan for changes"(steps shown in photo 2) to get the drive installed automatically.uninstall the drive and then reload itPhoto 2

2: If it did not work out, it may be the removable hard disk that is damaged! Try low-level formatting! {not recommended! You may try some other methods(included on this page) at first}
3: If all the above fixes does not work, you can use it on someone else's machine. If it worked fine on another PC, in this case = > there should be no problem with the hard disk. Try upgrading the Motherboard driver of your pc.

#2 Defragment on your hdd/usb/sd with chkdsk

For example: when you external usb drive shows drive H, here are the steps to do the repairing.

  • Open cmd from Run, and type cmd, right click to open it with admin priviledgeopen cmd as admin
  • Type H: and press the enter key
  • Type chkdsk /f and wait for the repairing

Or you may directly go with chkdsk h: /f from the second step

chkdsk repair disk

Here are several ways to clean the junks and repair logically damaged blocks using chkdsk.

  1. One: chkdsk /f
  2. Two: chkdsk /f /r
  3. Three: chkdsk /f /r
  4. Three: chkdsk /f /r /x

Reference: how to open cmd as admin (from grok.lsu.edu)

Some scenarios: It's a matter of fact that when you use chkdsk /f command prompt, it may directly show a message telling: Windows cannot run disk checking on this volume because it is write protected.

Note: It's the order that you need to firstly let the command prompt show how many disks, and then select the target disk, and let it show its partition list, and then select the target, and then type the command attributes disk clear readonly.

attributes disk clear readonly

Possible Reasons Behind "I/O Device Error" Problems

This "I/O Device Error" problem can be aroused by a series of reasons. Below are some major ones:

1). Faulty connection.
If this plunged storage device is incorrectly connected, you often will receive this "I/O Device Error" warning. When the computer USB port or storage device USB cable/USB adaptor or USB card Reader is damaged or broken, the computer is not able to detect your connected device normally and gives you such error message.
2). Device drivers
When the computer storage device drive is outdated, damaged or incompatible with your attached device, the common computer detection/reorganization also will be affected, which often bring you such error problems.
3). Storage device is detected with a wrong drive letter.
Sometimes, when your external hard drive, memory card or USB drive is recognized with a wrong drive letter, you also can get an "I/O Device Error" unwilling.
4). Damaged storage device.
Damaged or corrupted storage device (due to sudden computer shutdown/crash, unexpected device dropping/falling, device long-time use or too many device bad sectors, etc) also can result in unwanted device errors for users.

Tips & Notes:

1). Recover Device Data with Data Recovery Software before or After Format
If you do have to format this memory card or hard drive, to avoid unwanted data loss troubles, you'd better firstly try data recovery software to recover everything previously.
2). Attempt to use this storage device on another computer
Such "I/O Device Error" issues are not always aroused by the storage device problems. They also can be resulted by the computer problems. So, if you are really not sure whether it is the problem of your connected memory card or hard drive, disconnect it and try it on another computer to confirm. If it is the problem of your attached storage device, you often will undoubtedly get the same error again there.
