I would strongly recommend doing what DeHackEd
recommended (preferably with smartmontools 6.0, not something older, and using
-x
not
-a
). Getting SMART attributes from the drive will allow me to do a quick review/analysis of the drive and tell you what to look for.
If you're using the FastTrak 378's native RAID functionality, that may explain why you don't have a /dev/sdX entry for the drive (that controller is
extremely old and probably doesn't offer passthrough capability, so you would have to pull the disk off the controller and hook it up to a non-RAID controller temporarily).
"Swapping cables" sometimes helps only temporarily, when there is things like dust/debris in the SATA connectors or bad plating contacts on the SATA data port connector on the drive PCB itself -- but that problem manifests itself in a specific way (in SMART), so you have to have familarity with how to read the attributes to know what the problem may be. I've seen people report cable-swapping "solves their problem!!!" only to see a follow-up a week later complaining that it's still happening, where the root cause turned out to be excessive interference/noise inside of a case combined with not-so-well-shielded cables.
