[plug] WD-EARS 2TB drives and linux?

[Ari]

  Hi guys,

I think I may have made an error and I'm just now realising it. I have 
two WD Greenpower 2TB drives - one as an encrypted backup drive (using 
luks) and one as a storage drive (also using luks). I just fdisked them 
and put them to work. Now I'm hearing I should have realligned them or 
some such? I'm searching but not sure exactly what's up or if it's even 
applicable to linux (using Fedora Core 11). Any help would be greatly 
appreciated. The storage drive backs up onto a Seagate external 2TB 
drive, and the backup drive is a backup of two 1TB greenpower drives (I 
think). I'm freaking out just a little here about terrabytes of data loss!

TIA,

Ari
