What file system is used by a ReadyNas Duo?

What file system is used by a ReadyNas Duo (ver 1)? ReadyNas touts XRaid as its magic sauce for allowing the space to grow as a user hotswaps two newer, bigger hard drives for the older, smaller hard drives. However, is XRaid the file system used? Or is XRaid used in addition to file system such as FAT16, FAT32, NTFS, Ext2/Ext3, ReiserFS? I really doubt it is one of the first three because those were used by Microsoft Windows.

I have at least one dead hard drive from a readynas duo, and am still diagnosing the second hard drive. Both drives failed at the same time. I receive no email from the system saying that a drive was about to go bad. On the first drive, I know that 2k bytes on hard drive (address x000 to x799) are all zeros courtesy of Disk Internals' Linux Reader. My gut suspicion is that the MBR and partition info were stored in that location. Would Disk Internals Partition Recovery tool (which can read Ext2/Ext3) be useful in this case?

If the second drive is just as bad as the first, I need to know what my options are. Should I just chuck both hard drives and the Ready Nas Duo? I am assuming that the disk drives on the v1 HCL are no longer available.

    EXT3 with a 16k block size is used.

    One of the disks is the parity disk and would not have the partition table on it. So don't assume a disk is bad if it is missing the partition table.

    What model disks are these?
