I have a 512 mb Sandisk Micro USB thumbdrive that has worked great for a while now. I recently tried to delete some files from it and couldn't. It gave me an I/O device error saying the task could not be performed.

I can copy the files and paste them elsewhere, but I can't cut, delete files on the drive and cant add files to the drive. All attempts get the same I/O device error.

I copied all the data off the drive and tried to format it, however at 99% complete, I get the same I/O error and says format could not be completed. I went into disk management to delete the partition and try to format, however the delete partition option is greyed out and cant be selected. I have tried it on 3 different PC with the same results, two XP, one 2K.

Anyone have any suggestions on how/if it can be saved?

Thanks
 
contact sandisk. they replaced my cruzer thumb drives several times. sometimes they just stop working.
 
This probably ain't your problem but, is there a write-protect switch on it that you have on? That stumped me for a few mintues the first time I got one.
 
I think he'd get a write protect error instead of an I/O error. That usually points to either a currupt FAT or, the NAND has bad blocks. Time for warranty repair.

I have the 512mb sandisk cruizer micro. Mine did that one time when I plugged it into a mac. :p It worked fine on the mac, but then when I brought it back to my pc at home, it had all sorts of errors and stuff. It turned out the mac put some stupid hidden files and stuff onto my cruizer micro. I had to take it back to college, plug it into the mac, then delete the files using the mac computer. I came home, plugged it back into my pc, and it worked fine.
