bitor,

I was serious on a 99.99 % failure rate. It can be done, but requires some carefull planing. I only think v1, 1000 works for this converson.

Do not know if drive are required to be M/S or CS, my guess M/S.

You MUST TURN off Reboot on changes. Because when you change the unit from 1 drive to 2 it will reboot and say good bye to your working snap. You must then reload the OS, before the reboot. Once reloaded, reboot the unit with 2 drives attached and see if it comes up.

As far as loosing data. It MAY be there but you may need another 1000 to read the HD, because your MB will be locked up. I have one here right now, from a user attempting the smae stunt.

My thoughts, When you make this change the snap (trys to) reboot, does not find the hardware it is looking for or software, because it reboots before a user has a chance to load it. The unit is now LOCKED UP, with no way to clear the flashram or change the setting back. If you already have 250 gig and need more space by a larger HD. If you want a RAID, buy a unit that supports it.

Now there is a 2000 board that works on both 2000 & 4000 units. Don't know the PN.

DO THIS AT YOUR OWN RISK, NOT RESPONSIABLE FOR DAMAGES.
