I'm using TestDisk in an attempt to recover a partition gone terribly awry. Identifying the partition in question should simply be a matter of simply recognizing the location in the disk that it occupies. Since I know the location of the partition in question from GParted, I need to translate that over to the format that TestDisk uses, which I can't quite figure out.

GParted gives the First and Last sectors as follows:

First Sector: 1708032

Last Sector: 54637719

Total sector: 52929688

Test Disk gives the partitions in the following way:

Start: 1691 110 20

End: 4986 39 5

Size in Sectors: 52929688

My question is: how do I translate the location specified in GParted to that in TestDisk?
