How do you do it? Ive got 2x 750GB Hard drives on my server - it only shows 1, and says there is RAID1 on it. So how can i disable RAID1 so I get the full 1500GB. I don't care about data loss, and I can reinstall the OS/Software after - so can anyone help me out with this? Ive looked around on google, but I can't really find anything useful. Any help appreciated.
RAID1 is mirrored disks. The data that is on one hard drive also exists on the second hard drive. This means that one drive can fail and your server would still be up and running and functional (though you would want to get the bad drive replaced as soon as possible). Because the data is mirrored you only see the 1 750GB of disk space. To combine the disks you want a striped disk, or a RAID0 setup. This would combine the two disks and make one big 1500GB drive. However, if one of the drives fails, then you've lost everything. One drive cannot operate without the other. I'm not sure what the use is for this server, but generally a hosting server would want RAID1 because it gives fault tolerance in the event of a hard drive failure. It is less likely that both drives would fail at the same time. So this in effect gives you better uptime because you can withstand one drive failing and you haven't lost any data. If you are wanting to combine disks, I would recommend looking into a RAID10 setup, a 4 drive minimum setup that basically combines RAID1 and RAID0. If you are sure that RAID0 is what you want, you will have to have the drives reformatted and set to use RAID0 instead of RAID1.
