I got the "This disk is unreadable by this computer warning", which seems quite strange? I ran First Aid via Diks Utility to no exciting results. I finally got a SATA to USB cable and plugged the internal disk into another MacBook Pro. I don't recall there being anything super important on the computer, but I'd rather try more data recovery options before wiping everything and doing a clean install of some OS (of course, assuming the disk itself is not the problem). I've also read the hard drive cable can become damaged with time, so I was considering buying a SATA to USB adapter and trying to access the internal SSD from another computer, so as to determine if the disk itself is still working. Where do I go from here? I could try Clonezilla, but my understanding is that it can be quite painful to use. Mount: /media/newhd: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error I again get an error message, this time it reads: In the Ubuntu terminal, which again shows (among other things) my internal drive (it appears as /media/newhd). I then tried booting into Ubuntu with the same flash drive, which worked and ran Restore failed, could not validate source - error 254

Disk Utility sees my internal drive, but when choosing Restore I get the following error message: I rebooted into recovery mode so that I could use Disk Utility to copy the computer's drive into an external HDD. I first tried rebooting it again, to no avail. I restarted it and got a blank screen with a blinking question mark in a folder icon. I left it by itself for a while, came back, and it was still frozen. Yesterday, I turned my computer on, it booted normally, I logged in, startup programs opened up, and then it froze. The computer has an SSD that was installed about 5 years ago to improve performance. A few days ago, I booted into Ubuntu from a USB drive on my late 2011 13'' MacBook Pro.
