In reply to Samhrutha G's post on August 31, I followed the procedure suggested by Meghmala Support Engineer: I copied the contents of my flash drive to another XP computer and then tried to format it on mine. The same happened when I chose FAT. It only worked with exFAT this option was there beacuse I installed the relevant patch. Then, of course, the drive was not readable by the other XP computer, which does not have the patch! It seems that, after installing the patch for exFAT, my computer is unable to read usb flash drives or format them in FAT32 or FAT, although this didn't happen immediately!
