This is a Seagate 3TB NAS drive.
Installs NL2 fine to this drive, enter licence, activate, format disk-0, boots and runs fine.
But the NL2 format utility only formats about 5000 inode blocks, and so the total available space is reported as about 700GB.
What happened to the rest?
This was a fresh drive - brand new - I learned my lesson about drives with previous partitions on them in another thread, but NL2 seems to be fighting me again.

EDIT: Puppy Linux 4.3.1 sees all 2.7TB of the drive, but will not allow me to delete the NASLite partition - PL crashes when I try to use GParted to get rid of it.

EDIT: OK, I have just rebooted the CD-ROM of NL2, and the install utitlity sees the drive as a SCSI with a capactiy of 2.9TB. I therefore select option 1, to install NL2 to this drive, and make the rest of the space available for storage. Sounds about right. But once rebooted, licence added, activated and disk-0 mounted, space is 700GB.
I don't understand....
The install clearly sees it as a 2.9TB drive, but once installed, NL2 refuses to talk to it - something wrong with the NL format utitlity, me thinks....
