Hey, I'm actually a Mac guy, have a G4, a powerbook, and 3 iPods, however a friend of mind gave me his Windows iPod (4G Click Wheel) and it has HDD issues. I got it into Disk Mode, charged and restored it on a Dell at work and am trying to reformat the disk. I know that disk utility on a Mac allows you to format a disk and zero all data. It is a long process, but really cleans the drive. I figure doing this and restoring again may resolve this iPod's problems. I have tried right-clicking on the iPod in Windows Explorer (it is a mounted drive E: ) and have already checked it for bad sectors, and am now trying to use the format option in the right-click menu. It shows the volume, but the file system is blank, so is unit allocation size, and when I hit start it says ok to continue, cancel to quit, but ok doesn't start the format. Any suggestions. Does anyone know the command lines to do it through the Command Prompt window. Thanx.
