After migrating from Raid 1 to Raid 5, how do I access my files?
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.

Yes, I've rebooted a couple of times.
I'm running Win XP Pro (32).
Sorry, I don't have the system report from when I ran the migration and the volume expansion. Here is what I have now.

Thanks, SysExpert>
Is the 2TB limit applicable in this situation? I am using the ICH10R controller and I am under the belief that it allows for volumes greater than 2TB. Also, the weird thing is that the hard disk's capacity is listed as ~750gb while the partition on the hard disk is listed as ~1.5tb. Any thoughts?

Thanks, Rockchalk & SysExpert. This is what I was guessing but it's good to hear others confirm it.
The data on the 750GB volume is mostly inaccessible. Files are either missing (I originally had ~1.2TB of data in the raid1 setup before migration), or they are not playable (device I/O error). Fortunately, 90% of the data is available on other drives and the last 10% is only from the last 2 weeks so I believe I will be able to get them again. If someone could figure out a way for me to access that 10% of files, all the better. Otherwise, it's no big deal.
One more question: I've read somewhere that converting from basic to dynamic disks allows a partition to go beyond the 2TB limit. Is this true of a hardware raid or just of software raid setups? I don't mind splitting the array into two 1.5TB volumes, it's just that it would just be more convenient as a single 3TB volume.
I was freaking out for the past couple days but after a relaxing Sunday afternoon with TV and pizza, I realize this is not the end of the world. Thanks again guys.

I just had a thought. My OS is not on the raid volume. If i upgrade to a 64bit OS, would I be able to see the full raid volumes?

Or upgrade to Vista to setup the raid volume as a GPT disk (altho that would mean a fresh format). If I do upgrade to Vista, do I need to convert each individual non-Raid disk to GPT first and then setup the array or setup the array first and then convert the resulting drive to GPT?

Also, could you please post the system report from the Intel Matrix Storage Console here? There should be the option to save the system report under the File menu.
