[QUOTE="chscag, post: 1172307, member: 46727"] First of all, I don't know why you had to assign a drive letter to an external drive in order to "see" it in Windows 7? The drive should have mounted automatically and been assigned the next available drive letter. So that tells me something was wrong with the drive. If you originally formatted that drive to FAT-32 using Disk Utility from your Mac, it may have been formatted using the GUID scheme instead of MBR. That will mess over a drive because it places an EFI hidden partition on it consisting of 200MB. That may be why Windows 7 needed to assign a drive letter to it. Anyway, I'm not sure what you did... but it appears your drive is unusable. You can try fixing it by following these instructions: [URL="http://pitumbo.com/how-delete-gpt-partition-or-efi-mac-hard-disks-vista-or-xp"]LINK[/URL] Note: After doing this, you'll need to partition and format the drive again. If you use Disk Utility, make sure you specify the MBR partition scheme otherwise you'll have the same problem again. [/QUOTE]
