Drive disappearing until being reseated

I have a  3TB Seagate drive that it dropping off with write errors. I'm thinking of replacing it but the problem is SMART looks fairly clean and when I reboot to put it back into the array, it actually shows as "No Device". Is it possible that the cabling / my server is losing connections somehow?

 

Every time I reseat it, it works for a week or so and then write errors out again.. It's a HP Microserver G7; the bays are just slide in cages.

The last bit there is me trying to probe with smartctl (but it was already "dead" I/O errors). Syslog repeats the write errors up there for a bit longer.

 

Reseating it I suspect will make it show up again per usual.

    Is it possible that the cabling / my server is losing connections somehow?

    How does one diagnose / fix this?

    I would suspect a disk problem,  healthy SMART does not always mean a healthy disk, change the slot with another disk on the microserver, if the disk fails in a new slot it's the disk.
