Formatting Freecom Datatank in RAID0 with EXT3


I just got a 1TB Freecom Datatank: it's an external hdd case with two 500GB drives in it.

The device came with a windows-only utility which lets you set it to either JBOD, RAID0 (mirroring) or RAID1. I used a friends computer to set it to mirroring, after which the drive was automatically formatted in NTFS.

NTFS was working fine on my ubuntu machine. But I prefer using EXT3, so I reformatted the drive using qparted. Upon formatting, I noted the following output in my shell:
- FORMAT /dev/sdh1 ext3
Error: File system has an incompatible feature enabled.
Also, if I check the properties of the drive using gnome, it tells me that 23GB are in use: (I have not written anything to it yet)

However, this is not what df -h reports:
magli@mogster:~$ df -h /dev/sdh1
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdh1             459G  199M  435G   1% /media/DataTank
Why the inconsistency?

Apart from this, everything seems to work fine. However, I want to be sure that the mirroring mode is still functioning properly. I guess this mainly depends on how it is implemented on the device. Does anybody here know if I can rest assured? Would you, in my shoes, be confident that my data is going to be retrievable on one of the disks in case one fails?
