partition type 165

Hi all,

I'm trying to recover some data from a HDD recorder that has died. (issue with the power circuit that can't be fixed). Now I try to read out what is on the HDD. After a few bumps, I now can read some info off the HDD. But here I'm stuck. Don't know how I can mount the thing. Here is the info I already gathered:

gpart show -r da0
Code: 
=>        1  156301487  da0  MBR  (74G)
          1          3       - free -  (1.5k)
          4  156301484    1  165  [active]  (74G)
gpart show -r da0
Code: 
=>        1  156301487  da0  MBR  (74G)
          1          3       - free -  (1.5k)
          4  156301484    1  165  [active]  (74G)
gpart list da0
Code:

Any help info would be appreciated.
 
That's actually the container partition type for MBR partitioned disks, it is not mountable as it is because it is supposed to contain the actual partitions. The naming goes like da0s1 for the container partition and da0s1a, da0s1b etc. for the partitions. From the looks of it the partition information is lost for some reason.
 
@roddierod: the HDD comes from an HDD recorder (PVR). I don't know how it was used. The recorder was from 2005 (so I don't know if we can call this old).

@kpa: if I read the HDD (MBR) manually could I get more info? Already done that, but don't actually know where to look for extra info. Here are the first 512 bytes from the device:

I recall a similar case here some time ago and in that case it turned out that the PVR used a custom disk format that resembled the BSD partitioning but wasn't readable in FreeBSD. This may be in same boat.
 
The reason I thought it was an old release is because back in the 3.x and 4.x days you would format the disk using the number, as I recall.
 
Thanks guys.
Looked further, and from what I read, it is a sort of FreeBSD partitioning, but customized. So standard tools can't read it out. So that will be the end of this story I think.

Thanks for your time.
