0.125-7

But I downloaded 0.129 yesterday and compiled it (I cannot install it 
system-wide, as I'm not that expert to know what stuff needs to be copied 
where, and I don't want to break this system). I tried to run udevadm and 
vol_id from the place of the compilation, the former didn't work, the latter 
gave the same result as in the 0.125 version:

# ./udev-129/udev/udevadm info --query=all --name=sda
device node not found

# ./udev-129/extras/volume_id/vol_id /dev/sda2

Yes, it's their simplest 2-port card, model name 1220SA I think. It has a 
Silicon Image chip on it, the kernel use the sata_sil24 driver to reach the 
drives.

Attached. I hope I did the right thing. I got the offset and size with 
dmraid's help (dumping raid metadata). So these dd commands resulted the same 
files as dmraid -rD:

dd if=/dev/sda of=sda_ddf1.dat bs=1 count=6144 skip=200048559616
dd if=/dev/sdb of=sdb_ddf1.dat bs=1 count=6144 skip=200049641472

(As I wrote, because one disk has a HPA, the offsets do differ.)

Thanks,
Peter
