I don't understand either......I formatted the drive in FAT32, and just tried again, and it didnt work. Inserted the drive in the rear USB header and right clicked selected FORMAT and then FAT 32......message states that contents will be lost......clicked OK and hey presto its formatted to FAT 32.
I then used the UNetbootin installer and pmagic iso file.......pressed F12 for the HDD-USB....selected it and I got.......wait for it an......error message.
Did it with FAT and it worked....go figure......is it the pendrive itself......I also tried another pendrive...same outcome.
So if you format your pendrives in a different way......I'm all ears.
Bizarre or not.....that's the outcome and well it worked.
