Jun 14, 2015 at 11:14	comment	added	ID-ZERO		I was first using Ubuntu 14.04 Server 64-bit, but I used SystemRescueCD to make the changes, and seeing if the disk now works on Win 7 and xubuntu.

Jun 14, 2015 at 8:18	comment	added	ID-ZERO		I have done as above, and now gdisk thinks it's a 746GiB drive with no partitions. `Command (? for help): p Disk /dev/sdc: 1565565872 sectors, 746.5 GiB Logical sector size: 512 bytes Disk identifier (GUID): Partition table holds up to 128 entries First usable sector is 34, last usable sector is 1565565838 Partitions will be aligned on 2048-sector boundaries Total free space is 1565565805 sectors (746.5 GiB) Number Start (sector) End (sector) Size Code Name`
Jun 14, 2015 at 7:30	comment	added	ID-ZERO		So if I understand this correctly, I should do `gdisk`, then `o` - Create new empty GUID partition table?
Jun 14, 2015 at 5:21	comment	added	mikeserv		@ID-ZERO - the latter. That partition table is a map: it exists at the head of the disk - it doesn't write anything over when you rewrite it, except the old partition table. Of course, without the right map, the OS doesn't know where to look for fs superblocks, and so doesn't know where the filesystems are on disk, and so can't mount one. But if you can recreate the map exactly, then the OS will find all of the data exactly where it still is.
Jun 14, 2015 at 4:35	comment	added	ID-ZERO		Thanks, but by 'fix it' do you mean it makes a blank disk that is usable, or that the old data is still readable? Because this disk has a lot of data I want to be able to access.
