I have a Lenovo ThinkCentre M900 Tiny (10FL) which has been working fine. Recently, I had an HDD failure, and replaced it with an SSD. This time, I decided to go with ZFS (single drive, kinda pointless, but I get scrubbing). Every once in a while, I’m getting errors while scrubbing. It’s always 1-2 read or write errors. And it never reappears if I clear the error and run another scrub.
The data isn’t important, and it’s backed up, so I’m not too worried about it. But, the symptoms make me think that it’s an issue of the SATA port inside? Is it possible to replace the SATA port inside this device. I wasn’t able to find anything like part number etc. online and it looks like I need to replace the whole board. Any help is appreciated.
Have you checked the SMART value 199/0xC7 “UltraDMA CRC Error Count”? This should tell you how many checksum errors happened on the SATA interface between the CPU and the drive. If this is higher than zero your hypothesis is correct and there’s something bad with the connection, if it’s zero then the problem is more likely to be elsewhere.
Seems to be zero. Here’s the whole smart output in case anything pops out.
