I'd start with a check of the drive's S.M.A.R.T reported health status and
run some tests. As root run 'smartctl' to get overall health:
# smartctl -a /dev/sdX
A nice HOW-TO is here:
https://docs.slackware.com/howtos:hardware:smart_hdd_diagnostics
and
https://wiki.archlinux.org/title/S.M.A.R.T.
If the drives are failing within the warranty period, get them replaced!
Ed,
Thanks. I completely forgot about SMART. There's only the one drive acting
up now.
The results of smartctl -a /dev/sde don't look encouraging; it's not in the
SMART database:
# smartctl -a /dev/sde

I have two WD Red Plus 6TB NAS drives in my Synology NAS and they seem
fine. But given recent WD legal history, I may pass on additional WD
drives. I'm also slowly swapping out the old WD and Seagate 500 GB and 1
TB mechanical drives (now > 5 yrs old) with NVMe and SSD 1 TB drives as
cash and sales permit (4 TB replaced, 4 TB to go!). Mechanical vs solid
state both have their pros/cons and for me solid state is a better choice.
Given the smartctl results above perhaps I should replace it with an SSD
rather than another WD Red hdd.

Rich
