I'm looking to purchase a 2TB SATA hard-drive, and I want to get an external e-sata enclosure for it. When looking for possible enclosures I have noticed maximum storage limits for them (eg 750G, 1.5TB etc).

Is there really a size limitation for a basic enclosure, or is it simply that the manufacturers are simply protecting themselves with the largest size drives they happen to have tested with?

Not really, no, the specification were probably written at a time when 1 or 1.5 TB was the maximum available size for consumer hard drives, 2 TB HDDs only became mainstream very recently.

i recently replaced 2 original 500 GB drives with 2 TB drives in 2-year old Toshiba enclosures, no problem.

Have encounterd an issue where the power supply would not power a newer drivve. Did not seem to the size per se. Maker was Macally and they offered a new power supply (at about the cost of a new enclosure) – Dave M Feb 3 '10 at 22:14
