A friend just asked me about upgrading a HDR so I said he needed a AV disk, such as WD10EVDS. However those now seem to be difficult to get hold of and the replacement - WD10EURS - is an 'Advanced Format' disk, i.e. it uses 4096-byte sectors internally instead of the old standard of 512-byte sectors. I believe that in principle the disk should work with OS drivers expecting 512-byte disks but what of the practice? Has anyone successfully used a 4k byte sector disk in a HDR?

See this post.

Ah, that talks about setting EURX disks to SATA II mode, but it does link to http://myhumax.org/blog/?p=399. That article does seem to suggest that 4k sector disks will work if partitioned properly. Thanks for the link.

The WD10EURX is an Advanced Format disk - which the poster on MyHumax managed to get working once he set it to SATA II, according to that thread.

Not that the SATA mode is related as such, but by getting that drive working it appears to have shown that AF disks can work, and that this particular model does.

Reading that it's not completely clear whether it was necessary to partition it separately or whether the Foxsat HDR would have been able to format it itself though.

The HDR will format drives up to 1TB, but anything larger have to be formatted prior to installing in the HDR.

But Advanced Format (4k sector) disks? That was the issue - read the thread. The Humax was only ever designed to use 512-byte sector disks, so whether it will partition 4k sector disks is 'suck it & see'. The myhumax poster I referred to above partitioned his disk externally on a Linux system.

I have just bought a WD10EURX,(before I read this thread) and am trying to figure this out too. I will get some of the mentioned jumpers and see if that works first, it will be a few days before I can get any though, so I will post back when I find out.

Well, I put the jumper on pins 5&6 of the WD10EURX and the new drive was formatted by the hdr, working well.
