There are 2 4000 motherboards. 1 is the same used in a 2000, the other has a different PN.

As long as you test by failing drives. Power cycles while drive is failed, do not skip the one. Verify that it has reported the HD failure, and is running in degraded mode. If it will go into panic mode it did not like it.

These units DO NOT SUPPORT HOT SWAPING, so you must power down to replace the drive.

Phoenix is our resident hardware man. He did extensive testing in this area. What ever he says goes. So if you have something that is different you may not have found where it had the problem. He did not just fail a singel drive he tested by failing ALL, one at a time. Yes very time consuming, due to re-sync's. But it is the only proper way to test. Because he did discover if you failed some drives every thing worked, till you failed 1 specific position.

Maxtor were the drives that had EIDE problems. But who would want to use a HD's that has the highest failure rate in the industry for critical data.
