Hi,

I have been having weird crashes while boot of my hibernated desktop 
machine. First symptom appears to be stuck bios on detecting devices. I 
hit reset, continue. Machine boots, restores hibernation, and when going 
to display graphics, suddenly crashes and reboots. Of course, a reboot 
on an hibernated machine is a kind of catastrophe: many files are open, 
and the mandatory fsck of ext4 partitions takes for ever.

Happened 3 or 4 days. Tonight I noticed a strange message about a SATA 
interface going to 1.5 GB. Crash.

I track that message:

And sure enough, the DVD reader/writer unit is unable to mount any DVD, 
even to eject it.

Dead.

(I don't think I have seen test software for DVD units? :-? )

I have unplugged the SATA cable from the computer to this DVD unit. 
Let's see if this way it does not crash.

And I was not using the unit. It just had a forgotten disk I had read a 
week or two ago.

So... now I have to get a new unit. It will not be an LG again, bad 
hardware. I have seen a Liteon or a Samsung for about 16€. Wow, these 
things are cheap now. Cheap as dirt, and reliable as dirt, I guess. 
Sigh.

Is it worth it to get a unit capable of Blu Ray? Last time I looked, 
write media was very expensive, and people were having problems writing 
to them in Linux. Is it still true?
