I accidentally deleted the partition table of a 1.5TB drive with about 10 partitions on it; I'm running
testdisk now but it's going to take a while to scan everything.
I do have some useful information which I'm hoping can speed things up - the partition layout and filesystem types (mostly NTFS, some FAT32, EXT3/4). Unfortunately there are a few unknowns with the partition sizes. I do have another disk with a backup of (most) of the partitions, but there may still be some unknowns.
Is there any way to use the information I do have to speed up the partition table recovery, or do I just need to wait for the exhaustive scan to finish?
