When Seagate FA Goflex Desk is attached to a USB 2.0 port under Puppy 4.3.1 Pmount gives red popup with the text, "unable to mount sdx1".

It shows the drive as being 746.56MB in size.

Lupu has so far given no problems mounting the drive on the USB 2.0 port, although in it pmount variously shows the drive as "300TB", and as:

" ntfs 357.7G [with] 2794.1G free"!!

That one is easy to answer,
Puppy 4.3.1 goes not contain the driver for the "Free Agent" drive.
There was also another drive that required a driver for it to be recognized.

In Lupu, the code that checks the size of the drive/partition was not made to allow for really large hard drive sizes. The big question here though is to if Gparted would see the full drive size.
Loosing capacity/space on the 3T drive due to software not being able to handle partitioning of it correctly would not be a good thing.

the kernel of 4.31 is too old.
I use Fluppy 013 to be able to use a 3 terabyte drive from Western Digital.
I have only USB-2 ports, and cannot use a USB 3 PCI-Expresscard, because the slot is covered by the passive cooler of my graficscard.

But I had the same issue with Puppy 4.31, because of the old kernel, Fluppy then solved it.

yes, it was not correct to close the thread, as it seems to be a different issue.
However, we now hijacked this thread, so lets continue here.

So different to Puppy 4.31, Lupus Kernel supports the large size, if I understand well.

There is just an issue with pmount? Or with the USB 3 driver?

You might try muppyquickmount:
http://www.murga-linux.com/puppy/viewtopic.php?t=32107

I use it in Fluppy with the USB 2 ports, and it reports correct sizes.

So a comparison with pmount might be interesting, wait... hmm.. also pmount shows correct values, they just slightly differ from Muppyquickmount.

I'm actually not following the development, so cannot help further, sorry.

Have now succeeded several times in mounting the 3TB Free Agent Goflex Desk USB3.0 drive under lupu 5.2.8, but ONLY on the USB 2 port. In fact, it can be hot plugged on the USB 2 port.

OTOH, every attempt to mount it on a USB 3.0 expresscard adapapter using lupu USB3.0 driver fails. A desktop icon appears for the drive (if it's attached and powered up at bootup), which gives the correct size when the cursor is passed over it, while Pmount shows it as 300TB/357GB. But all attempts to mount it produce a red popup "unable to mount sdx1".

Meanwhile, a smaller Freeagent Goflex 500GB drive mounts on the USB 3.0 port without problems, so long as it is present when lupu boots up. Hotplugging doesn't work on USB 3.0 ports, although it's fine on USB2.

I conclude the problem is in the USB3.0 driver. No such problems arise in Win 7. Both drives mount and can be hot plugged on either USB 2 or USB 3

After resizing the 2.9TB ntfs partition to 1.9TB, it mounts and writes normally without error messages in Slacko 5.29.6, lupuk3.07 on either USB2 or USB3, and even in Puppy 4.3.1 (on the USB2 port).

Lupu 5.2.8 continues to mount the partition read only, and Wary gives a red popup warning, but allows writes to be made.
