After migrating from Raid 1 to Raid 5, how do I access my files?
Posted on 2008-11-02
I previously had a Raid 1 setup on two 1.5TB Seagate drives on my ASUS P5Q Pro motherboard (with ICH10R SATA Controller). The resulting disk was setup as "basic", not "dynamic". I recently purchased a 3rd 1.5TB Seagate drive (identical to prior 2) and used the Intel Matrix Storage Console (ver. 8.5) to migrate the Raid 1 to Raid 5 (no other options selected). After the migration completed successfully (meaning the wizard finished), the size of the drive was exactly the same. I looked into Administration Tools>Computer Management>Storage>Disk Management (Local) to view the resulting drive and it was still listed as roughly 1.5TB (instead of 3TB as expected with the migration to Raid 5). I went back into Intel Matrix Storage Console, right clicked on the Raid volume and clicked "modify volume". There was an option to "utilize 100% of available array space" so I ran it. 10 hours later, the initialization completed and only some of my files on the volume are viewable thru windows explorer and none are playable (these are all media files).
Although the resulting disk shows as ~1.5TB in My Computer and Administration Tools, the disk is listed as ~750GB within the Intel Matrix Console. Not exactly sure what's going on but I suspect the "basic/dynamic" disk has something to do with it. Should I have converted the raid 1 disk from basic to dynamic before the migration to raid 5? Thanks.
