under nt 4 you could not include the boot drive in the stripe set with parity. And I thought this was also true under win 2 k server. But recently I read you could use the boot drive and if it failed all you needed to do was replace the bad drive..can anone clear this up.. thanks

If you have a hardware based RAID and your OS reads it as a single drive the boot drive can be a RAID array. If you configuring a software RAID you will need a separate boot drive.

On RAID 5, data are break into segments and every segment is stored on each hard drive. Parity code for each data is counted and stored on another drive.RAID 5, with its parity, is able to restore broken data if only a single failure (1 segment loss). So that replacing a fail drive of RAID 5 pool will activate data recovery to rebuild the broken part.

Matt, lets combine those two answers. Windows 2000 lets you combine the boot partition in a stripe set with parity, regardless if you have hardware raid or not. So, if you don't have hardware raid, don't combine the boot partition in the stripe set with parity under win2k, becuase it will let you and it wont work when one fails. I PROMISE.
