I'm using a Sandisk 4GB flash drive on a Win XP machine and just found it cannot be read anymore. The OS keeps telling me the disk cannot be read and if I'm to reformat it now. I have some important files on the disk, so I dare not to reformat it, nor have I tried any data recovery softs, because I'm just not so sure of it.
Here are some background information which may help clarify things a bit more:
(1) I've repeatedly write and rewrite the flash drive during the last two days. I think its getting to its full storage capacity.
(2) The computer has been suddenly shut down (I don't know the exact cause) for two times when the USB flash drive is connected to the computer.
While I'm aware of I'm not alone running into this problem and there are couple of tentative solutions on the internet, I still feel like your good tips and suggestions to encourge me.
