[bolwerK]

Hi we forward the answer of micha to asses our smart error.
she is willing to do a session next week. who wants to be with us and 
stay in the loop for making an appointment?
maybe we can have a look together before we ask her advice.

hey!

sorry for being so late with the response... my first week back in nyc 
has been crazy busy with work and seeing people but things are finally 
calming down.

SO! UNCORRECTABLE SECTORS! This is generally a really bad sign and shows 
that the hard drive is starting to degrade. If you ARE NOT using some 
sort of RAID system where your drives are redundant, I would IMMEDIATELY 
backup the data on the drive and start finding a replacement. It is only 
a matter of time before that drive dies.

If you ARE using RAID and would rather keep that drive alive as long as 
possible, you can isolate the blocks and attempt to reset them. This 
will trigger the firmware on the hard drive to either a) repair the 
blocks or b) choose to not use them for future storage. Smartmon's 
documentation has a good tutorial on how to do this... I recommend going 
through the whole thing and BACKING UP your drive before attempting the 
fix: https://www.smartmontools.org/wiki/BadBlockHowto

Before any of this though, it may be good to run a smartmon long test to 
verify the results of the short test. You can do this by running `sudo 
smartctl -t long /dev/sdb`. You can get the results with `sudo smartctl 
-a /dev/sdc`, noting that a long test can take a couple hours to 
complete. This is a good page for basic smartmon usage: 
https://www.thomas-krenn.com/en/wiki/SMART_tests_with_smartctl

Also, if you are hungry for more drives, I have an extra Western Digital 
RED 8TB (one of these: 
https://aphnetworks.com/reviews/western-digital-red-wd80efzx-8tb). I can 
ship it to you when I get back to france on the 18th.

Anyway, I'd be happy to do a little debugging session together this 
coming week if you'd like!
