2TB Hard Drive - Problem getting Humax T2 to recognise it

I partitioned it using gparted (using Ubuntu).

I'm not sure which format of partition able it used ... whichever is the default I suppose (I was going to look into that if it didn't work using the defaults). I could have a look at the settings in gparted to see what it's set to now - alternatively is there a way to check by querying the drive itself?

The same's true of the cluster size - presumably I can query the drive to see what it is...?
Presumably you formatted it in gparted too, in which case you might not notice a problem until you have more than 2TiB used.

One way to check might be to run a file system check in maintenance mode. If it passes you should be fine but if it fails it might be this problem or a lack of memory. See the Wiki but I would suggest running 'e2fsck' with the -n option which will check the disk but not make any changes. I'm not sure how long it would take but it could be anything up to say 2 hours.
I'm sure I don't mean sector size - that would require a low-level format to change, but fair enough.
Ok, not quite what I was hoping to hear...

I'll run the check when I can next get to the box and report back.

Worst case I'll revert to plan B and swap my 3tb and 2tb drives over.
If you try 'cat /proc/partitions' it should give the sizes that the kernel is using for each of the disks/partitions. These are counted in blocks of 1024 bytes.

e.g for a 2TB drive:

major minor  #blocks  name
  8    16 1953512448 sdb
  8    17 1953511424 sdb1
OK, a couple of command outputs for you...

humax# cat /proc/partitions
major minor #blocks name
8 0 782782932 sda
8 1 782781440 sda1

humax# fdisk -lu
Note: sector size is 4096 (not 512)
Disk /dev/sda: 801.5 GB, 801569722368 bytes
255 heads, 63 sectors/track, 12181 cylinders, total 195695733 sectors

I've not run the e2fsck command as yet to check the drive but will do when I get a chance.

I am having a couple of problems at the moment with what look like permission problems so I'm tempted to reformat from scratch again and only add the files and folders that are absolutely necessary (rather than adding the mod and Video folders from my old drive) and see what happens then.
I think this is probably OK. It is the first time I have seen a disk with a 4K sector size used in an MBR (msdos type) partition table.
