My computer was manufactured in 2006 and has Intel matrix storage manager v.5.1. Original configuration had (2) 160GB drives with Raid 1 mirror. One drive failed about a year ago and was replaced with a 320GB drive. Raid 1 was reconfigured and since one of the lower volume drives was still utilized, the total volume size was 160GB. A few days ago the other original 160GB drive failed and was replaced with an identical new 320GB drive. Raid 1 was reconfigured again and now utilizing (2) 320GB drives, however now volume size total still shows as 160GB not 320GB. Is there a way to re-create Raid 1 that will increase the volume size to 320GB?
