But isn't this a 2nd hdd, i.e. sdb1? sda1 would be the 1st partion on your 1st 
drive as I understand it correctly.

Did windows per chance crash on an earlier boot? I've found ubuntu wont mount 
the drive if windows crashes and isn't rebooted 1st to fix the log entries. 
Meaning you need to reboot windows successfully and then reboot ubuntu for 
the drive/partion to show up in ubuntu.

Alas I can't help on that count :(

I'd be surprised if there was a conflict with the ntfs file system. Have you 
installed ntfs read/write support? I did so on my laptop via automatix and it 
works fine for me. Only time I have any probs is if windows crashes and I 
forget to reboot windows 1st b4 restarting ubuntu.

Your fstab would seem to suggest the drive/partion is being detected and set 
as mountable. However u seem to have sumerized the fstab lines rather than 
give the actual ones? And tell me about vist probs. Dual booting vist and 
ubuntu on the other laptop

The fact that sdb1 shows sometimes and not at others reminds me of a post I 
saw when searching a lil while ago. That one ended up being a bios setting 
fro the drive. Might I suggest looking at the available options for it in  
thrhe bios? Maybe the clue is there
