I have just lost my laptop (Thinkpad T61p - graphic card failure/no boot) and to add another blow I cannot read my main SSD drive now which means Iím losing about 4-5 month worth of my lifeís data. Iím trying to recover that drive.
When the laptop died, I took out the SSD drive, put it in a USB sata encolsure, and connected it to another (olde) laptop running Ubuntu (10.04). It worked just fine and I could see my files. Later that evening I tried to use that drive to boot another similar T61p but the laptop wouldnít boot, falling into Grub rescue mode saying there is no file system.
I immediately reconnected it to the USB enclosure and now instead of seeing my files I get nothing. Iím pretty sure the drive was ext4 (default file system for Ubuntu 12.04).
The usual investigation produces the following:
dmesg after connecting the drive:

mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
After mount attempt, dmesg adds this:

How can I recover the drive? Should I use dd to mirror it on an image file locally and experiment with that? Is there a way to extract the data out of it? I have lost lot there since my last backup and it would mean a lot if I could get it back.
