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.
