Hi.
I have been given a USB 1TB Hard drive to work on that has just failed.
The Drive is a western digital Elements 1023 1TB. Externally powered.
The drive was formatted under Mac OX 10.5. It has been partitioned into 2 * 465 GPT partitions, plus the protective MBR partition (apparently FAT32.. Strange... maybe because it was formatted on a Mac??).
The drive stopped working on the Mac after it was brought on an international flight from France to Vietnam, where I am.
First thoughts: physical failure. But the drive has not been bumped or dropped, and surface scans and integrity checks reveal that the drive is healthy. It sounds to be running smooth and quiet.
The computer being used to analyze and fix the drive is running Windows 7 X64. It recognized and installed the hard drive immediately.
However, the drive does not appear in explorer and is not assigned a drive letter.
The drive does however appear to be functioning normally and is visible under device manager.
I am unable to assign a drive letter using Disk manager (greyed out) or EASEUS partition manager.
Formatting is not an option because this is the only copy of the essential data that was brought over. EASEUS lists the GPT partition types as "other".
So where do I go from here? The drive appears to be healthy, and I suspect the issue is to do with Windows recognizing the GPT file partitions. The thing to squish that though is that it stopped working on the Mac also.
I'm not familiar with macs so in addition to advice on where to go from here, I'd like to know about any possible issues I may experience trying to fix a Mac formatted 1TB USB HDD with GPT partitioning under Windows 7 x64.
I'm thinking maybe try find some software that scans and analyzes the GUID file table? Thoughts?
Update: I've just run Testdisk and it finds no problem with the file structure.. I think. It detects the GUID file system and says all partitions are healthy. Is this simply an issue of trying to plug a mac hard drive into a windows computer and the users who gave me the hard drive have a problem with their computer? Should I be able to access this hard drive on this computer?
Update 2: Testdisk lists the Gpt partitions as type MAC HFS+ and it appears windows 7 cannot read this by default?! So I guess now what I need is Windows 7 software that allows me to mount and analyze a MAC HFS+ hard drive?! Is that correct?
Thanks for your help.
