hostbyte=DID_BAD_TARGET ?, drive dropped, and readded ?

Postby lbm » 2017-10-18 07:54

For the last couple of weeks, I have experienced that some (different) drives are disconnected (one at a time)..

First I replaced the drive without so much fuss, but then it happened again, with a different drive.
I then started to look through logs, and now I see this. sdh is dropped, because some sort of failure, and then later on added again as sdi ???
This drive is almost brand new 1,5-2 months old, and I've tested with smartctl which does not report any errors at all.

I strongly doubt its actually disks which are failing, but any ideas what it then could be?

as I have read from this thread, it's probably one of your hardware is failing, check the cables, connections, mobo, smell, chair, or anything related...


am so funny.

Disconnect the cables, check them closely, if you have a multimeter, check all the pins for continuity, if not change the sata power cables, change all the cables, change computer, desktop, chair, head lights, buy a car, good job, we did it
