It is a Veritech 2GB flash memory.. I tried it on some computers.. they recognize it, but when I double click it to open it, it doesn't open and a message box says that it's not formatted, do you want to format it?... I tried to scan it by antivirus but nothing appeared... I tried to format it by right clicking it.. it didn't work.. I tried formatting it from the command prompt but it even didn't work... As you can see in the attached picture, the disk is shown full and it says 0 bytes used!! also it shows no file system! I think a virus corrupted the file system FAT32. What do you think and how could I fix this flash memory?? any help?
