I have just bought a new Sandisk Cruzer 8GB flash drive. I plugged it into my Vista laptop which recognized it as new hardware and it appeared as it should in Explorer. I then removed it from the machine using the safe to remove option.(right click context menu) Upon reinstalling it into the laptop it does not now appear in Explorer - nor does it does show up as a portable device in Device Manager but it does appear in Administrative Tools/Computer Management/Storage/Disk Management. If I reboot with the flash drive installed it does then appear in Explorer. (I also have a 1 Gig Kingston drive which works perfectly.)
Pineman100 I will only recognize it if it is rebooted with the flash drive pre-installed. I have noted that in Computer Management when the drive is recognized after a reboot as above it is allocated a drive letter but when I just insert the drive although it shows up in Computer Management it has no drive letter allocated - nor will it let me allocate one.
