I am trying to recover the ext4 partition table of a 2TB disk, where I have 900.000 files. I have cloned the original HD and now I am working on the cloned HD. And I am running Parted Magic Live CD.With testdisk I got what it looks like the original deleted partition:Disk /dev/sdd - 2000 GB / 1863 GiB - CHS 243201 255 63Partition Start End Size in sectors>P Linux 0 1 1 243200 254 61 3907024000 [Duo]Anybody can help me to read this numbers? As far as I know, I can use this data with the mount command and, if everything goes right, have access to the files in order to start a file transfer, can't I?According to this man page, I can use data extracted from testdisk to help me fix the partition: Now using the value given by TestDisk, you can use fsck to repair your ext2/ext3 filesystem. I.E. if TestDisk has found a superblock at block number 24577 and a blocksize of 1024 bytes, run:  # fsck.ext3 -b 24577 -B 1024 /dev/hda1But I don't know how exactly.By the way, here it goes some more useful data from gpart:# gpart -gv /dev/sdddev(/dev/sdd) mss(512)Primary partition(1)   type: 131(0x83)(Linux ext2 filesystem)   size: 1907726mb #s(3907024000) s(63-3907024062)   chs:  (0/1/1)-(1023/254/63)d (0/0/0)-(0/0/0)r   hex:  00 01 01 00 83 FE FF FF 3F 00 00 00 80 74 E0 E8Primary partition(2)   type: 000(0x00)(unused)   size: 0mb #s(0) s(0-0)   chs:  (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r   hex:  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00Primary partition(3)   type: 000(0x00)(unused)   size: 0mb #s(0) s(0-0)   chs:  (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r   hex:  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00Primary partition(4)   type: 000(0x00)(unused)   size: 0mb #s(0) s(0-0)   chs:  (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r   hex:  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00Begin scan...Possible partition(Linux ext2), size(1734848mb), offset(2mb)   type: 131(0x83)(Linux ext2 filesystem)   size: 1734848mb #s(3552968704) s(4096-3552972799)   chs:  (1023/255/0)-(1023/255/0)d (0/0/0)-(0/0/0)r   hex:  00 FF C0 FF 83 FF C0 FF 00 10 00 00 00 00 C6 D3According to this post I can use this information to help me:This time I got something useful. The s(63-117258434) part shows the starting sector, which is 63. A sector is 512 bytes, so the exact starting offset of the partition is 32256. So to mount this partition, just issue:  mount -o loop,ro,offset=32256 /storage/image/diskofperson.dd /mnt/recovery And voil, access to the filesystem has been obtained.  /storage/image/jdiskofperson.dd on /mnt/recovery type vfat (ro,loop=/dev/loop0,offset=32256)Any help would be great.
Use testdisk and gpart information to mount ext4 partition
