Drive failure and ASUS

Drive failure and ASUS

[Gene Heskett]

Greetings;

The only way I can get this box to boot is to disconnect the data cable on a 
drive with 121 badblocks as somehow ASUS and JMicron-pata all seem to think 
its /dev/sda when hooked up, and it is no longer bootable.  I'm presently 
booted from a sata drive on that interface, which this ASUS board has about 8 
of.

So I've booted with the data cable off, and hooked it up once booted.  Unforch 
there seems to be no discovery of its presence.

No /dev/sdd stuff was created when I plugged the data cable into the drive.

The install is the August 2008 F8 respin and is uptodate.

How can I make the system aware that it is now there?  It has about 40 Gb of 
data I'd like to recover if I can.

Thanks.

The bad disk is PATA?

Hotplug isn't supported with PATA, so you shouldn't really try that. 
Fedora installs usually use labels for the disk partitions, so it 
shouldn't matter what device node the disk gets detected as?

It isn't but if you're willing to accept the risk of frying the
controller and/or the drive, it works.  I sometimes do that which
sometimes makes the whole machine shut off instantly.  :-)
