hdparm fails to handle security configuration...

[Daniel J Blueman]

Binary package hint: hdparm

When adding hdparm disk unlock commands to /etc/hdparm.conf, we see it fail to specify the password:

/dev/sdb {
 user-master = u
 security_unlock = letmein
}

-> simulate udev event
# DEVNAME=/dev/sdb bash -x /lib/udev/hdparm
...
+ /sbin/hdparm -B254 u -q --security-unlock /dev/sdb

-> additionally 'man hdparm.conf' states 'security_mode = u', which should be 'user-master = u'

[Daniel J Blueman (danielblueman)]

With the above fixes, we still meet failure:

# DEVNAME=/dev/sdb bash -x /lib/udev/hdparm
...
+ /sbin/hdparm -B254 -q --user-master u -q --security-unlock 'letmein' /dev/sdb
# echo $?
22

-> this is because the security commands are exclusive within hdparm, so this is needed:

# /sbin/hdparm --user-master u --security-unlock 'letmein' /dev/sdb

-> though we are closer

This bug hits me too and prevents hard disk hot-plugging in Thinkpad Ultra Bay:

root@karmic:/home/callweil# /sbin/hdparm --user-master u --security-unlock 'letmein' /dev/sdb
security_password="letmein"

/dev/sdb:
 Issuing SECURITY_UNLOCK command, password="letmein", user=user
SECURITY_UNLOCK: Input/output error

hi,
how to understand "SECURITY_UNLOCK: Input/output error" ?

is it because the passwd is wrong or the disk is not working as hdparm expect ?

can you post your dmesg following this error ?

because i am facing a similar issue
