Hi Ted,
many thanks for dealing with this matter! Unfortunately I cannot produce such a 'dirty' partitition/filesystem, as my QNAP-NAS heavily crashed during rebuild of that partitition sdc3 onto another disk and finally died (it is away for warranty repair ;-). The disk I have here is the disk which always remained in the NAS, I call it disk #2. Disk #1 I had pulled out and plugged in again to check whether the promised feature of hot-plugging and RAID1 really works. So, the information I can provide you with is the 'good' disk, which never was rebuilt! (I now plugged it into a external eSATA-box to collect this information).

First I copy you here the partitition table:

Platte /dev/sdc: 750.1 GByte, 750156374016 Byte
255 Köpfe, 63 Sektoren/Spuren, 91201 Zylinder
Einheiten = Zylinder von 16065 × 512 = 8225280 Bytes
Disk identifier: 0x00000000

   Gerät boot. Anfang Ende Blöcke Id System
/dev/sdc1 * 1 66 530113+ 83 Linux
/dev/sdc2 67 132 530145 82 Linux Swap / Solaris
/dev/sdc3 133 91190 731423385 83 Linux
/dev/sdc4 91191 91200 80325 83 Linux

If you now look at the size of sda3 (700GB) you understand, that I did not create an image of it before starting with fsck ;-)

Presuming that all 4 partitition have been formatted using the patched ext3, it probably helps you to have a look at the images of sda1 and/or sda4.
sda1 can be mounted, but only if you explicitely specify the option -t ext3
sda4 can be mounted, but only if you explicitely specify the option -t ext2
sda3 still crashes on Hardy e2fsck, despite Lenny's e2fsck has 'fixed' it.

What I can offer you at the moment is following:

1. partly image of current sda3 (dd if=/dev/sdc3 of=qnap-sdc3.img bs=4k count=200) -> attached!
2. bz compressed image of sdc1 (230MB)
3. bz compressed image of sdc4 (20MB)

After creating the images I again tried to e2fsck all 3 partititions under Hardy:
sdc1 and sdc4 perform correct, sdc3 crashes e2fsck.

If you are interested to have a look at QNAP's sources (should all be under GPL), please check here:
http://europe.qnap.com/download/Storage/TS-209Pro/
I guess, the sources should be in the last archive on that page (277MB).

If you need more information or upload the images of sdc1 and sdc4, please let me know,
Ingo
