External WD drive

#1 Post by kimbersc »

Currently have a 500 GB WD drive that has been working without problems using a Mac. I can't recall if I formatted it for use in both PC/Mac or just for a Mac. While it was connected, the connection to the hard drive came loose and the drive was unmounted improperly. Now when I connect the HD, the computer reads the "WD Smartware" portion of the drive but not the main partition. The first time I plugged it in I get the initialise/ignore popup. I tried running TestDisk, it automatically recognises the drive as a EFI GPT but when trying to Analyse it I get "Bad GPT partition, invalid signature". When I ran the drive as an Intel, I get the attached log. I tried running it on a deeper search but it freezes at 23%. Any help or guidance is greatly appreciated.

Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (499 GB / 465 GiB) seems too small! (< 4727 GB / 4403 GiB)
