I have a Dell Dimension E250, 3.0 GHz Pentium D, 3GB RAM. I had it running a RAID 1 array with two 160GB sata hard drives. The integrated mobo RAID controller is the Intel Matrix Storage Manager, driver version=ICH8R. I decided to upgrade to two 640 GB drives. What I did was pull one 160 and add one 640, booted in to Windows and had it "repair" the degraded volume on to the 640, then put in the other 640. It repaired perfectly. Everything is working properly except the partition size is still showing as 160 GB [technically 149 GB]. I don't know how to expand it to the full 640 GB [596 GB], or if it's possible. Any ideas or instructions are sincerely appreciated ~Hobbes
A mirrored volume is only as big as its smallest link even if you upgrade it after that. However you may be able to get around that if you use Norton ghost or similar imaging software to copy the partition over to the new disk, that might work.
When you repaired the RAID it copied the 160GB partitions from the old hard drive to the 640GB hard drive to maintain compatibility with the older hard drive but it is a partition so it will appear to be only 160GB even though there is extra space left over.
