I want to create a RAID-1 array for backups. just before you jump and shout at me "RAID is not a backup". I know HD are not expensive these days and buying another one is not the big issue. this will be abetter backup then not having back up at all, agree ? the machine is not working 24 hours a day, and mostly turned on when I use it. I don't want long back up process to run automaticely in the background at this time. other then that I mostly forget to do backups. for now I can only burn the data on DVD, but even a huge external HD won't help me remembering to back up so automatic backup in the form of RAID-1 is the best option for me. even in case of system crash I can use the drive as a second one (not bootable) to take read the data from it. now back to topic - I read WinXP does not support RAID-1, though I fread it possible to make it to support it. my mobo (MSI K9N6SGM-V) support 2 SATA drives and say it support RAID-0 and RAID-1. does this mean an hardware RAID, rather then software ? I have WinXP installed on my drive (Seagate 250gb SATAII). I don't want to reinstall the system. can it be done by buying another identical drive, and cloning the current disk to it (with something like ghost) ?
