I've bought a new 4TB hard drive, a Western Digital WD40PURX, to replace an existing 1TB drive, and because I don't have a free internal SATA port - I've used a USB-to-SATA adapter I had lying around to connect the drive temporarily so I can move the data over - before switching the drives.
But when I'm trying to partition the drive, Ubuntu only sees 1.6 TB of size:
# gdisk -l /dev/sdg
GPT fdisk (gdisk) version 1.0.1
Partition table scan:
MBR: not present
BSD: not present
APM: not present
GPT: not present
Creating new GPT entries.
Disk /dev/sdg: 3519069872 sectors, 1.6 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): B19A7DC5-52A5-44AD-B295-51C8853A9EBB
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 3519069838
Partitions will be aligned on 2048-sector boundaries
Total free space is 3519069805 sectors (1.6 TiB)
And here's smartctl
:
# smartctl -x /dev/sdg

I've search around for something like a size limit for USB mass storage devices, but that doesn't seem to be the case.
[Update]: After looking at the discussions pointed to by @Mitch, I've tried setting the drive to "Advanced Format" using a jumper, without success - after setting the jumper, the drive still identifies as "Sector size: 512 bytes logical, 4096 bytes physical".
I'd appreciate any thoughts on the subject.
