I have a SATA disk in an external eSATA enclosure. Most of the time it's powered off, but when I turn it on windows hangs for 15-30 seconds. No sound, no mouse, nothing. Then after 15-30 seconds, everything is fine again.
What could be causing this, and how can I fix it?
The enclosure is a Vantec Nexstar 3, and the disks have both been Western Digitals. (I only have the two to play with.)
