I have purchased 2 WD red 3tb drives to store my music library (it has outgrown the 1tb drives). One drive is the library, the other is backup. They will be housed in a Vantec 2 drive enclosure, connected via e-sata. I'm formatting them with windows 7 disc manager. The first drive seemed to format fine, although it took awhile. Windows disc manager indicated it was being formatted and showed progress as a percent. The second drive is recognized by Disc manager, but when told to format, process seems to hang. Disc manager says it is formatting, but it does not show any kind of progress as it did with the other drive. Would this indicate a bad disc?
I would try two things:
1) command line format, start -> run -> cmd enter and type in format drive /FS:NTFS /X
2) You can download HP USB Disk Storage Format Tool
If neither one those work and you already tried the disk manager approach, I would say, yes it is possible, it's a bad HDD.
