Hmm, damn.
```
hdparm -N /dev/[hs]d[a-z]
/dev/sda:
SG_IO: bad/missing sense data, sb[]: f0 00 05 00 00 00 00 0a 00 00 00 00 26 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
max sectors = 0/1, HPA is enabled
/dev/sdb:
max sectors = 5860531055/5860533168, HPA is enabled
/dev/sdc:
max sectors = 3907029168/3907029168, HPA is disabled
/dev/sdd:
max sectors = 3907029168/3907029168, HPA is disabled
/dev/sde:
max sectors = 976773168/976773168, HPA is disabled
/dev/sdf:
max sectors = 5860533168/5860533168, HPA is disabled
```
So, I need to run
`hdparm -N p5860533168 /dev/sdb`
I'll take a look at the bios to see if I can disable the hda feature for the short term. Long term it looks like I need a new mobo
Thank you so much for pointing me in the right direction!
As this is the parity drive, am I safe to assume I can either fix using the above command or obtain a larger drive for parity?
