NSA310 - External Drive Size limit??

Tubes

Hi Folks
Just upgraded my NSA310 with a new drive, and was going to use the old one as a eSATA drive. 
But it does not want to see it, tried creating it as NTFS and it says failed. The drive is being seen as I can see it with the SMART as it is listed (and front light says connected), but unable to create a volume etc. (I also formatted it on my PC and then plugged it in but that also did not get seen)
Its a 4TB drive (which worked fine internally) - is their a limit on external drive size??
I did mange to get it starting to format as a ext3 but it hung on 99%.

Cheers

Do not know how big size your external hard drive is, but if you're using large disk, the disk need to have its own power supply.

As I said its a 4Tb drive - if you mean what physical size its a 3.5 inch drive and has a power supply. Works fine when attached to computer (esata or USB), and inside NAS, just not as an external drive.  Works with no problems if I use a 2TB drive instead.

As far as I know there should be no other limitation than for the intern disk. When I remember well the 310 supports raid1 combining the internal and external disk.

Do you have shell access? Can you plugin the disk and than post the output of

cat /proc/partitions

su

fdisk -l
