SMART Error, but where?

HannesJo · 22. Januar 2020

I took my USB backup disk out of its case to see if there is any speed difference connecting it via SATA.
After doing so I just noticed some kind of SMART error on it. SMART -> Devices -> Overview shows red. But under Information -> Attributes, I cant find any error.
Extended Information:

(See attached)

Syslog has some messages like

Code

Is it possibly just because the controller has changed without reformat or should I get a new one? Thanks in advance!

EDIT
Ok there are definitely unreadable files. Tried to copy some with rsync and it says

I think it is no cable issue or so, since it is always the same sectors. Guess I am gonna get the retour carton ready.

The SMART assessment is checking this: https://github.com/openmediava…smartinformation.inc#L240

I assume that the bad sectors are the reason for the final assessment of your disc. The tooltip of the red dot should show you the reason.

HannesJo · 22. Januar 2020

Oh there is a tooltip, nice! Yes, it says Bad Sectors. Unfortunately reallocation fails. So is there anything else I could do or just change the disk? Data loss would be just a bit annoying but no real problem here.

subzero79 · 22. Januar 2020

Change the disk as soon as possible.
