Late to this thread but
Ultra ATA CRC errors are usually down to the cable. This thread provides other reasons tho' and maybe useful to readers.
https://superuser.com/questions/1294158/what-may-cause-very-high-crc-errors-on-ssd-apart-from-bad-sata-cables-if-anyI must admit that I have over the past year or so swapped most of my boot drives to SSds (Samsung) and I am concerned by the fact that SSDs can and will brick without any warning and unlike traditional HDDs once they brick it is virtually impossible to retrieve data.
As a consequence, I now back up my boot drive(s) very much more often and am using a belt and braces approach as regards disk monitoring by way of using paying drive monitoring software. I use HDSentinel Standard and HDTune Pro.
I had never purchased this type of software pre SSD but am pleased that I have then now.
HDSentinel in particular is truly excellent. I got two licenses during Black Friday deals last year for £18. I am sorry that I didn't purchase that particular software earlier.
Cheers
