I/O error on a 16GB SanDisk Cruzer Contour USB

Dear all

I bought a 16GB SanDisk Cruzer Contour USB stick nearly three years ago. It worked always fine until now. I never used any U3 utilities only the data drive. I only moved files from and to the data drive. From one day to the other the:

E:\ is not longer accessible.

“The request could not be performed because of an I/O error”.

While the F:\ CD drive with the U3 stuff is still accessible and readable.

I tried every kind of utility from disk managers to partition stuff, from Dos, Linux, Windows, tested it with different notebooks and workstations running Windows XP, Linux. I also disabled the Virus protection, without any success :angry:
I don’t know how U3 technology works and influences this product exactly, but I think it is the “driven factor of this problem”, as reported in many forums. However I tried also to disabled the F:\ CD drive in the device manager and the U3 uninstaller tool from SanDisk also failed with an I/O error.

Any other or new suggestions?

Thank you very much indeed for any feedbacks.

I doubt U3 has anything to due with your I/O problem, it sounds hardware related not software.  I suspect a wire or solder joint as become oxidized or broken.

On my windows 7 I am getting IO errors. What should I do next. This is a 16G chip for my LG cell phone,
