Please help! I can't access my USB flash disk. Whenever I click the icon of my flash disk on My Computer, it says: "F:\ is not accessible. The request could not be performed because of an I/O device error." I also encounter that same error with other USB flash disks I insert on my USB ports. What seems to be the problem?

What operating system are you using?

click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb drive but its not working

ports (com&lpt) right click update driver if this fails to fix the problem

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no

dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts

if you need more help with post a reply

Right click the icon of your Flash Drive (It should be F:/ or something)
Click Properties in the menu that comes up
Click the Sharing tab
Click permissions
And finally, click Allow next to Full Control.?

Hi,
Format your pen drive through computer management.
It will solve your problem

1. Go to desk top and right click on your my computer icon.
2. You will get one option called Manage.
3. Click on that , it will open a console.
4. Then click on disk management .
5. you will see your hard disk partition and pendrive.
6. Right click on your pendrive and format it.

Hope it will help you .
Thanks for using FixYa.

1) Instead of double-clicking, right-click and choose "explore." I hope it's that simple. Once you're in, look for a file called autorun.inf. Delete it.

2) If it won't let you explore, see if there is a "format" option instead. This will possibly solve your issue of access, and will solve your issue with your confidential data (of course, your data will be gone, but I'm guessing you're OK with that).

3) Try using another USB slot, sometimes there could be an issue with specific slots, especially if you are using hte front USB ports on a desktop
4) I know this may seem silly but turn off the computer, and then unplug the computer from the wall. Leave it unplugged for 30 seconds, plug it in and then boot up the systems. Plug in the USB drive.

5) Finally if the unit still is not being seen, it may need a low level format, contact the manufacturer and see about getting a replacement. I found their e-mail at [email protected]

Try these first

First off try it in a different computer and if that can read it then you know for sure that the problem is with yours.

If it does not read on another computer chances are the drive is dead and whilst uncommon it does happen.

Also if "shell hardware detection" is turned OFF in W7 then it wont tell you when it is plugged in but you can still read from USB devices. You just have to browse the "removable" devices from windows explorer Try them all if more than one is listed

Check if drive letter associated or a folder in MMC disk management

1. Download this tool:

2. Format

(Before removing USB flash drive click on the Safely Remove
Hardware icon and then click on USB flash drive you want to remove)
