I have a ocz Rally2 flash drive that has stopped working on one computer only (XP SP3). When I plug it in it shows up as E: but in disk management it is not present and if I select properties in explorer then it shows as having zero space available.
I have checked the drive in two other computers, one XP and the other Win7, both show the data and device correctly.
I managed to get it to work once before by removing all the old flash drive instances from device manage
cd C:\WINDOWS\system32 SET DEVMGR_SHOW_NONPRESENT_DEVICES=1 devmgmt.msc
then selecting show hidden devices and all the non connected devices show up and you can remove them. I did that and then was able to get the flash drive to connect properly.
Now I can't get it to attach correctly.
