I lent my Usb Pen drive to a friend who needed to create a bootable usb disk. On getting it back, I formatted it on Windows but… it would then only work in Windows!!! Not on my beloved Kubuntu!
I tried several utilities, software,… and it only ended up in manking my pen drive useless (impossible to read from and write to) on both Windows and Linux
So the solution (just a wild guess) which finally worked was to format the pendrive as a FAT32 drive in DOS!!! Now it works on Windoiws and Linux. How, Why, … I don’t know but it works. Thank God!
So the command was simple:
format E: /FS:FAT32 (where E: is my pen drive name and FAT32 is the fle system I want on the disk)
For more help on the command, type format help at the dos prompt.
