Windows 7 - "Please insert disk" error in pen drive

Hey Guys, i have Hp 8gb Pen drive and when i inserted in my pc it it says "Please insert disk into Removable disk"..when i tried to format it, i got the error "there is no disk in the Drive..Please insert drive and try again"..I have very important files in it.. I tried on another pc but still got same error...can any one give me some solution for that...even if my data is not recovered, it will do but i need my pen drive back..Please HELP me..!

This can happen if your flash drive tries to use a drive letter which is already assigned to another drive.

1) Insert your removable disk into the USB port.

2) Click Start, right click on Computer, then click on Manage.

3) Now, click Disk Management.

4) Right click on your removable drive partition and select Change Drive Letter and Paths under Disk Management

5)Change the drive letter to something like X: or Z: which is not reserved by some other drive on windows.

I tried that...but still having the same problem..

Well if nothing works, just right click on the drive in Disk management window and click format.

There is no option in it to format it..and when i try to format by right clicking on its properties it says " Please insert the disk and try again"...Plz suggest any other solution..

Try HP's USB Format tool.
