Like many of you, I own several USB Flash drives. My latest additions were two 8GB SanDisk Micro Crusers with U3 bought at two different times over the last 3 months. They have been working flawlessly up until 3 days ago. When I inserted a drive into a USB port, the amber light came on for 1-2 seconds and then went dark; it did not show up in Windows Explorer or Hardware Manager. The same thing happened with the second Cruser drive. I then tried some of my older USB Flash drives including two PNY 1GB drives and a 2 GB SandDisk Micro Cruser Skin drive; they all worked as did my PNY Media Card Reader for Secure Digital cards. ALL of them worked when connected to the computer (Dell Dimension 4550, Intel P4, 2.53 GHz, 1GB RAM running WinXP HomeSP3). I tried the two 8GB Cruzers on the rear USB ports: they still didn't work. I tried them on my laptop (Lenovo duocore Intel Centrino, 1 GB RAM running WinXP Home) and they BOTH worked fine!! They also worked on a new Gateway AMD QuadCore 2.2GHz with 3GB RAM running Vista.
I cannot use any jump drive utilities because the drives do not connect to the computer. It's as though when it is powered up, it senses that there is something wrong and immediately shuts down. I also understand that I cannot add a new driver to the computer without having the jump drive up and running; is this true?? Why would I need a driver any way?? I am considereing getting another 8 GB (or less) SanDisk Micro Cruzer with U3 and connecting that; that might install a new driver that all of them can use, or it might put the new jump drive into the same condition of not working on this computer.
Should I consider "disabling" or "unistalling" (which??) all the USB Ports one at a time (all at one time??) to see if that resets / reinstalls a non-corrupted dirver?? BTW, I have rebooted several times including with one of the non-working jump drives inserted in a slot, but there was no change in the outcome.
I don't think it is a failure in the jump drives themselves in that (1) they are both really new, (2) it happened to both of them the same night (they were, however, plugged in separately) and (3) they both work in my other computers!!
Have you heard of this before?? Got any suggestions??
