Hey all. I just thought of something for this. I have an older Western
Caviar 36400 hard drive that disconnects once the computer goes to
sleep. Currently, I disallow sleep mode for that very reason. But
anyway, I'm curious if it's safe to do a reset of the IDE controller.
In my case, the drive is currently on primary slave. I moved it from
secondary master.
Right now, I fear if I hard-reset the IDE controller (a Via 686
UDMA100), I might also disconnect the primary master (Quantum fireball
6.4SE). That will render my box useless until I hit the the reset
button. But, if I do a soft-reset, the caviar may not wake up. I know
the quantum will wake up fine upon a soft-reset and upon resume of the
system. I'm going to try putting in interrupt 15 (secondary IDE) as a
primary power event in my bios and see if that can wake up the drive.
Oh, if you're curious, here is my fstab:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hda6 / xfs defaults 1 1

/dev/hda1 /win2k ntfs defaults,ro,user,uid=cappicard 0 0
/dev/hdb1 /win2k-driveE ntfs defaults,ro,user,uid=cappicard 0 0
As you probably see, if my caviar (hdb) disconnects, I'm pretty-much SOL
if I try to run X or any programs from /usr/*. And I have to resort to
SysRq to reboot the box (I hate finding a pen to hit the reset button).
I'll let you know what I find out.
