Severity: normal

hdparm 9.39 introduced support for the Write-Read-Verify feature on
some Seagate hard disks, using the -R option. See for example
http://www.altechnative.net/2011/04/06/enabling-write-read-verify-feature-on-disks/
However, apparently many disks reset this flag on reboot, and
/etc/init.d/hdparm does not have a way to enable it through
/etc/hdparm.conf (which is necessary if you want or need to do it on a
per-disk basis).
Attached is a patch for the init script on Wheezy which adds such
support, using the configuration keyword 'write_read_verify'.
