I'm using the older version (4500) and have not had these problems. I run the WD RE drives in my unit, that have been fully scanned by SpinRite. Spinrite will scan for all bad sectors and check every part of the HD. This eliminates the lag and randon errors. My guess they are use the cheap Maxtor drives. I would stay on Adaptec CASE, they have a bad reputation when it comes to customer support. If you have a second one causing problem I would request to talk to a manager or use the sales rep that sold you the unit in house sales. The reps some time can pull strings an esculate the ticket. But Since they only offer 90days software support, unless you purchased a contract, STAY ON THEIR CASE, GIVE THEM NO SLACK.

SnapAppliance was a very good company before Adaptec bought them and basicly cut off all support to home users.
