Just started using this morning. &nbsp;I downloaded the secure access manager and tried to drag and drop files. &nbsp;On some files it will crash. &nbsp;The computer still recognizes the flash drive but when i open it there is nothing showing on the drive. &nbsp;The Icon is on my system tray but doesnt give you the option of opening it. &nbsp;Also when I plug it in it says it is automatically suppose to open the sucure access but it doesnt. &nbsp;I usually have to pull the flash drive out and re-insert it into the computer to get it to show its contents. &nbsp;definately fustrating.

"_&nbsp;I usually have to pull the flash drive out and re-insert it into the computer to get it to show its contents_."

Pulling it out, rather than Safely Removing it, can cause the Cruzer’s File Allocation Table to get screwed up.&nbsp; Try running CHKDSK for the drive and see if that helps.
