Hello.
As a rule of thumb (no pun intended) when asking for tech support help here or elsewhere, you should always include your computer’s operating system (Win98, 2000, XP, etc.) and in your case, the brand of flash drive.
I just experienced a similar problem with a Centon 1GB stick I got for Christmas. Even though several different computers recognized and assigned a drive letter, it showed no files and did not allow me to even reformat the thumb drive (”Drive not found!”).
My conclusion: Centon makes a crappy thumbdrive. I ordered and just received a Sandisk Titanium 1GB drive and it is working great so far.
In closing, remember that flash drives DO have a lifespan (in the millions of re-writes), ARE susceptable to static discharges (which will wipe them out), DON’T like to be dropped or jarred and if you have not properly STOPPED the drive before removal it could spell disaster and loss of data.
Visit the manufacturers website/support forum and read F.A.Q.’s. Double check to make sure your USB PORTS are working correctly on your P.C. If you are running on a Win98SE system, you were required to download drivers for removable media. You might need to uninstall and update the driver - check the manufacturer’s website for this. Did your flash drive come with a warranty? I have read that Sandisk customers have had items replaced in similar situations.
That’s all I can offer. I hope some info here has helped or educated you further on these tempermental (but handy!) devices.
Best,
Sam
