And the mirror would boot up?
But yes, if it's a true mirror then to get to the files you just pop RAID 1 (not 0!) into the usb enclosure and connect to a compatible OS like XP SP1 or newer.
I built a PC a few years ago which includes 2x 250Gb Western Digital SATA II hdds in a RAID1 array (with jumpers to slow them to SATA 1).
The PC is currently not booting and the problem appears to lie within the Graphics card or Mobo. Whilst I attempt to fix that, is it possible to connect one of the two HDDs from the RAID array to another PC to read the data from it?
The RAID controller is on the MOBO (ASUS A8V-E deluxe VIA VT8237?)
Is it as simple as getting a SATA-USB HDD Enclosure and plugging it in? Will the RAID1 create any problems with this?
