[Solved] ata15: SError: { UnrecovData BadCRC } (SMART looks fine)
I'm getting ata15 errors during boot sometimes causing the system to hang for about 10 seconds before continuing. I've checked SMART and everything is fine. I had expected to see some UDMA CRC errors, but I'm not getting any. Below is from dmesg -e, followed by smartctl.
I also would like to say this should be completely unrelated to my issue last week with the whole suspending to memory bug with btrfs.
sda is a ST2000NM0053 with a GPT partioning table. If I had to blame a drive that would be my first since it is the newest.
sdb, sdc, and sde are all 1TB WD RE4's. I've been running them faithfully for between 3 years to 8 months.
sdd is a HyperX 3K on loan for testing bcache. It's not in use, but I haven't disconnected it (though I should, and will).

Hi, According to errors message, the problem is in the link layer.
Identify what disk is connected to ata15.00 (ls -l /sys/block/sd*), and replace the cable.
[edit2] Within a week I've run a long SMART test on sda, the new drive (simply because its new), and it passed.
[edit3] It is definitely looking as if it was either the cable or the SSD. I'm not getting any errors of the kind I was seeing and I've finished the extended SMART tests.

I can't find ata15.00, however that's probably because I disconnected the SSD, and changed the cable on the new drive. Thank you. I'm glad to know that its probably a cable issue.
I'll give it a week and then mark this as solved if there are no further problems.

For the new drive, sda, before anything else I ran a long SMART test as well as a single pass of badblocks. I've also recently run a long SMART test on the oldest RE4, sdb. I am, however, at you suggested, now running a long SMART test on the other two drives, as well as rerunning the test on sda. Thank you.
