I have same problem. In Snake 1.20. The Hard Disk is a Samsung HD154UI 1,5 tb size.

The hard disk is formated normally, but wont mount.

I have a 3TB (2.7) with 4 partions. (WD By Book)

In ssh to snake fdisk -l reports...

Disk /dev/sdb: 801.5 GB, 801535688704 bytes <<<<< NOTE HERE THE 801.5GB
255 heads, 63 sectors/track, 12180 cylinders <<<< AND 12180 cylinders
Units = cylinders of 16065 * 4096 = 65802240 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/sdb1               1       11400   732557312  83 Linux
/dev/sdb2           34200       45600   732558336  83 Linux
/dev/sdb3           22800       34200   732558336  83 Linux
/dev/sdb4           11400       22800   732558336  83 Linux

In debian it reports...

Disk /dev/sdb: 3000.6 GB, 3000558944256 bytes <<<< HERE Correct 3GB
255 heads, 63 sectors/track, 45599 cylinders

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       11400   732557312   83  Linux

/dev/sdb3           22800       34200   732558336   83  Linux
/dev/sdb4           11400       22800   732558336   83  Linux

Only the 1st and 4th partitions will mount. The 1st seems fine, the 4th mounted but gave errors list directories, and then when brought back to debian needed an fsck to fix something.

I am using snakeos-V1.3.2-20101130-from-original.bin. My little 320GB hard disk is fine.

Thanks for you time.

Same problem:

BusyBox v1.18.5 (2011-10-19 23:26:11 CEST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

# fdisk -l

Disk /dev/mtdblock0: 0 MB, 262144 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/mtdblock0 doesn't contain a valid partition table

Disk /dev/sda: 1500.3 GB, 1500301910016 bytes
255 heads, 63 sectors/track, 182401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/sda1   *           1      182401  1465136001  83 Linux


The snake print:

Device	Vendor	Model	Size	Action
sda	ST1500DL	003-9VT16L	1048575 MB

That looks like one of those new 4k or "advanced format" drives. I guess the kernel doesn't know how to handle those.

The fdisk output doesn't look that off. Can you try to format the disk on another computer? Temporarily using an usb stick as swap disk while formating may work too. mkfs.ext3 likes to run out of memory on large disks.

The snake output is unusual. The value is calculated by dividing /sys/block/sda/size (number of 512 byte blocks (I guess 4096 for newer drives)) by 2048. I can't imagine how it got to that bumber.

You need to compile the kernel with GPT partition support so that it can understand 4k block size.

I have this same issue with a 4TB hardrive USB. Someone with some solution already?

I have the same issue with a USB 3TB Seagate drive after a Snake OS Format. Also only have  about 700MB total space.  But I can see it as share in WIN 7 network when its connected to NAS.   
Now I can't see the drive in WIN 7 explorer now. So I can't format in WIN 7.

Any way of re-formatting the USB drive back to NTFS?
