[ale] OT: hardware question

[lists at serioustechnology.com (Geoffrey Myers)]

Okay, to try and get this on topic a bit, I am running Centos in a VM on 
my macbook, but I have a repeating problem that is baffling me.

I upgraded my drive to a 7200 750g drive a while back.  Soon after, I 
started having problems that seemed to be drive related.  The drive was 
still under warranty, so I returned it, purchased another identical drive.

All was good for a while.  Now, I'm having issues again.

Here's the odd part.  I generally leave my laptop up 24/7.  I only have 
a problem when I shut it down and then reboot.

When I attempt to reboot, it won't.  I go into the disk utility and 
check the disk for errors. Sure enough, errors.  I fix them, reboot all 
is well.

This happened twice this morning.  The last time, I didn't even try to 
boot it, I went directly into the recovery mode, fired up the disk 
utility and sure enouch, checking the disk shows errors and says I must 
fix the errors.

My point is, if the drive is going bad, why don't I have issues with the 
laptop when I leave it up for extended periods of time?

Do you folks think I've just gotten into a bad batch of drives?
