Recovering partition table on a large Mac drive

#1 Post by bitstreams » 06 Mar 2015, 22:52

I'm trying to recover the partitions on a Mac format external drive - I'm doing this on a Windows PC running testdisk under Windows.

The Quickscan shows 2 partitions which I believe is wrong, as the Mac partition just looks like the boot drive. I'm therefore running a Deeper scan.

Almost immediately it gave 15 MAC HFS lines (screenshot attached).

The drive was in a caddy attached via USB3 - I left it running but after a couple of hours it hadn't reached 1% (it's a 3TB drive). I calculated that at that speed it would take 5 days to complete. I removed the drive from the caddy and attached it via SATA and started again. This time I think it's a little faster, but not much.

Do I have any option but to wait for it to complete? Is it slower running within Windows ? Is it likely to speed up on empty areas of the disk or can I predict the run time as I have been doing?

regards
Simon

After 24 hrs it's at 49%

The list of Mac HFS entries is the same as before
