And that one quit answering the phone fron smartctl yesterday afternoon.
That was my backup src. So that cable will be hooked to a 1T SSD yet
today which will be formatted and /home copied to it as that is a huge
majority of what I need for a backup. Thats next on the agenda before I
do anything else. If I casn get a sata power cable out, that might get
done w/o a powerdown since that seems to be the reinstall generator.
Got that done, hooked a fresh data cable up to /dev/sdc's socket on the
mobo, then carefully inserted the power plug, and /dev/sdc just reported
a temp change from smartctl's scan.
But while I was doing that, I wrote a copy of LinuxCNC's latest buster
install iso to a key, so if I can get it to boot from a key, I'll have a
buster install ready to go.
The raid10 is sde-f-g-h, and this drive I must have had it the raid
before , and is now showing up at /dev/sdd. and on further checking, I've
rebooted since disconnecting /dev/sdc, and udev has helpfully reset the
drives on damned letter down, to d-e-f-g. grrrrrrrrr. But where the hell
is it, the drive I just hooked up is marked as an EVO-870 but /dev/sdc is
an EVO-860 & 500gigs. /dev/sdb is a 240G ADATA 650, and /dev/sdc is
reporting its a EVO-860 of 500G. Obviously fdisk is getting bogus data
from some place. You'd better hope I can reboot. But first clean up /
dev/sdb and reformat & copy /home to it so I might stand a chance of
recovering my work.
Have fun Charles cuz I sure as heck am not.

Its in a card cage with a big fan in front and the psu blocking the rear,
It will be a powerdown to do that. But I don't have much hope, the cable
I unplugged to get it off the bus was plugged in correctly. If I can get
the power cable unplugged, then its drawer can be removed from the front.

That would be nice, if the change was easy to do insitu. Its not.
