If that is indeed the case, you can control it with "hdparm -N" (see its
man page).
Just checked out the man page, and ran "hdparm -N" on all RAID member
devices. They all report that HPA is disabled.
e.g.
$ sudo hdparm -N /dev/sdc
/dev/sdc:
max sectors = 586072368/586072368, HPA is disabled
This number of sectors does seem like it would fit all the partitions from
the previous array. However, the Size reported by mdadm seems to be
smaller than what hdparm reports, judging from the error messages below.
