I’m going to take the drive to a recovery service in Studio City this afternoon to get an estimate. Meanwhile, I want to boot back into my regular OS, but I doubt if I can do it without sdb1, because the fstab specifies that it overmount /home at boot. So I either have to set up one of the other drives as /home (not sure how to do that, other than mounting it and adding myself as a user) and make it sdb1, or get into the fstab on the SSD to tell it not to do the overmount. I haven’t been able to figure out how to read or write to sda3, which is my Fedora partition, to get at etc/fstab. Any ideas?
[Update a while later]
OK, I’m now booted into my regular system, with one of the new drives as /home. But since I currently have no data, there’s a lot of rebuilding and reconfiguring to do.
Off to Studio City now to drop off the drives.
