External hard drives won't mount

[Toredown]

For some reason, my external hard drives won't mount. I made a fresh install yesterday with iDeneb v1.4 two days ago and they have been working fine. Today, neither my Lacie or my WD MyBook are recognized at all. I can boot in XP and they are picked up fine.

 

Any ideas?

Curious, what drivers do you use for mounting? Are they stock ntfs driver or ntfs-3g? Did the system crash, while in OS X, while the drives were connected?

 

Id recommend a quick chkdsk within XP if you have it. Just open up the cmd line and type chkdsk "drive letter": /X /V /F /I /C

 

Should remove the dirty flag

I use MacDrive on my Windows machines, so one drive is HFS+ and the other is HFSJ. I checked them both out, and the Lacie did have some errors I'm going to have to deal with. The WD was fine.

 

Also, this computer is a brand new build, I plugged a third external drive (also HFS+) that has never been in contact with the machine and it did not register either. This makes me believe it's an issue with OS X and not the drives, though that doesn't get me any closer to figuring out the problem.
