The 500GB Seagate ST9500420AS (D005SDM1) hard drive in my 2011 Dell XPS 15 crashed the other day and, although I had the most important data backed up, I would really like to save the rest of it. It had been running Fedora (23, I think), had 3 ext4 partitions and 1 swap partition. I would be grateful for any tips on how I could access the partitions.
So, when I boot the computer I get the following error:
Operation system not found.
The BIOS diagnostic tool gives the following error:
Error Code 0147. Msg: Error Code 2000-0147. Msg: Optical Drive 0 - self test -- OPU failed.
I booted the computer from an Ubuntu 17.10 live USB stick and received a lot of kernel errors about the hard drive. The syslog is here: https://www.dropbox.com/s/86kyicthla8k367/syslog.txt?dl=0
There seems to be some kind of an input/output error, but Google hasn't got me anywhere yet. When I run Gnome Disks, it displays the disk as "500 GB Unknown" and no partitions, but in the "Assessment" field it says: "Disk is OK,one bad sector". (Screenshot: https://www.dropbox.com/s/b0fqe5vrwlc90gz/hd_problem.png?dl=0)
If I try to make Disks create an image, it says that it's unreadable and replaces the data with zeros.
If you have any ideas on how I could access the data again, I'd be really grateful.
