I had a couple of hard drives that I used in a Belkin network enclosure...by that, I mean they were formatted with some proprietary file system. I removed them from the enclosure and want to use them with a FAT32 file system. Problem is that I just cannot initialize or format them. I have attached them to my system with an external drive connection kit.. that includes a power cable and another EIDE to USB cable, that allows me to connect them to the system via the USB port. When plugged into my Mac (iMac w/SnowLeopard), the drive never shows as mounted on the desktop; when using the drive utility, the dive does not appear there either. So, I can't initialize or format it. I have also tried attaching the drive to several Windows systems (Vista, Win7), and none of them can see the drive either.. so I can't initialize and format from there either. Any ideas on how I can salvage these drives?
