Not format 8gb pen drive - SanDisk Computers & Internet

What's your meaning? Pen drive cannot be opened right now since it keeps asking you to format before any access? If so, do not worry! Such flash drive not formatted error problems do not indicate drive corruption all the time.
Merely go recover pen drive information with pen drive data recovery software and format this USB drive to see whether it can still work functionally as before.
If not, you may have to choose another new one for future use.
Go prepare pen drive data backups on different drives or locations well from now on.
