I've got a drive that's being quite difficult. Initially I started
reading the whole device (/dev/sdc) but due to the rapidly failing
nature after I had pulled the first lot of data off I decided to try
attack /dev/sdc2 directly (which is the Windows partition with the data).
Anyhow, due to changing my mind a bit, I now have two partial images and
I wish to merge them and then continue on with reading the *whole* drive
again; the drive now has lost the ability to read the partition table (
don't bother telling me to send it to a cleanroom, I've already been
over this with the client, they don't want to spend the $, they just
want to see what they can get off with software recovery ).
I have img and log ( ddrescue -v -f -O -P16 /dev/sdc img log )
...and I have img-sdc2 and log-sdc2 ( ddrescue -v -f -O -P16 /dev/sdc2
img-sdc2 log-sdc2 )
There's some degree of overlap; about 50GB of data in the img-sdc2 that
hasn't been (yet) picked up in 'img'.
Here's the main image.
Disk /dev/loop0: 698.7 GiB, 750156374016 bytes, 1465149168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xc1735e81
Device Boot Start End Sectors Size Id Type
/dev/loop0p1 2048 52430847 52428800 25G 1c Hidden W95
FAT32 (LBA)
/dev/loop0p2 * 52430848 681576447 629145600 300G 7 HPFS/NTFS/exFAT
/dev/loop0p3 681576448 1465145343 783568896 373.7G f W95 Ext'd (LBA)
/dev/loop0p5 681578496 1465145343 783566848 373.6G 7 HPFS/NTFS/exFAT
So, in summary, how can I merge what is recovered in img-sdc2 in to img ?
Regards, Paul.
