I bought a new hard drive to go with the one I had. Both are Seagate SATA 500gb 16mb cache drives. The one I had has been working fine in my computer. I installed the new drive and went into the BIOS and changed the settings to set up a RAID 0 array. After many problems I got Windows XP Home Edition reinstalled onto the computer. When I go into My Computer it only shows one drive and the storage space is 500gb. Any ideas on why the other drive does not show up?
If I right click on My Computer and click on Manage and open up Disk Management it shows:
Disk 0- 931.52GB It is designated as the C drive and shows it's capacity as 465.75gb. Right next to this information it shows another drive (it has no designation which leads me to believe that the two drives are set up correctly as a RAID 0 array). It shows it's capacity at 465.77gb and it says "unallocated". This second drive has never been formatted so I am wondering if that is a problem? If it is, how can you format a drive that is part of a RAID array without having to format both drives?
your RAID array is ok. both drive now show as one with 931gb, and that 931 drive just have 2 partition, one that is c: and the other, that is not formatted, will be of equal size of the other. just format this partition and use it.
remember that you are not working on one drive at the time, but on both that has been merged to make a bigger one.
