Thanks, just ordered the WD5000AVDS.
I’m planning to remove the old drive, connect both to a PC and clone old to new using clonezilla (on a boot CD), then a partition editor to enlarge the video partition and use the full drive capacity. Any reason that won’t work, or other comments?
PS Also, is it good idea to do anything else, such as replacing the fan, while I’ve got it open? It’s getting on, I got it within the first week or two after it first appeared.
