mounting a 16TB USB on Fedora 40

[Ranjan Maitra]

I recently got a 16TB USB disk and was trying to mount it on Fedora 40 using spacefm. I get the following:

Mount /dev/sdb:

Status: Finished with error (Exit status 1).

Object /org/freedesktop/UDisks2/block_devices/sdb is not a mountable file system.

My first instinct was that I got taken for a ride so I hopped over to a colleague's Windoze machine, but there the USB drive is visible (with the capacitty of 15.2 GiB, as expected).

So, is there anything special that I have to do to mount it on Fedora 40, because of its size?

Thank you for any suggestions, and best wishes,
Ranjan

What does the tail of dmeg say? I believe that's where you will see
the initial kernel and udev activity.

One comment here... I understand the counterfits have an additional
chip or logic that misreports the size. The real problems do not
surface until you actually try to use the space. So plugging the usb
drive in may not be enough to validate the drive. Instead, you want to
write a 12 TB or 14 TB of data to ensure it's not a 256 GB or 1 TB
drive.

I think that you need a number after sdb .
Do you have it formatted as one massive filesystem?

I expect you meant 15.2 Tsomething.

I think that here is the relevant output from dmesg. Let me know if you need more information.

I see, thanks for this information. I was not aware.

Just to be "safe," I formatted it using that Windoze box. It appears to be formatted as one massive file system?

Yes, right: I have never seen such a massive USB which is why I got it to check it out:-)

You could try 'lsblk /dev/<device>' and see what that outputs, see if that
helps make sense of a) the device's partition layout and b) any filesystems
on those partitions. For example:

root@fedora:~# lsblk /dev/nvme0n1
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
nvme0n1     259:0    0 953.9G  0 disk
├─nvme0n1p1 259:1    0   600M  0 part /boot/efi
├─nvme0n1p2 259:2    0     1G  0 part /boot
└─nvme0n1p3 259:3    0 952.3G  0 part /home
                                      /
And then 'lsblk -f /dev/<device>' to show what's known about filesystems:

# lsblk -f /dev/nvme0n1
NAME        FSTYPE FSVER LABEL                 UUID
        FSAVAIL FSUSE% MOUNTPOINTS
nvme0n1

├─nvme0n1p1 vfat   FAT32                       DC0B-5B4B
          579.7M     3% /boot/efi
├─nvme0n1p2 ext4   1.0
3352353a-c664-4631-aec0-82ba2ceec4bc  614.8M    30% /boot
└─nvme0n1p3 btrfs        fedora_localhost-live
96a27e82-57ae-4b15-9beb-f5c856c2638b  831.6G    13% /home

/
 I suspect if you've formatted the disk on Windows you'll have NTFS or
exFAT?

Based on the Buffer I/O error, this could indicate a failing drive;
see https://www.reddit.com/r/debian/comments/omic2r/buffer_io_on_dev_sdb_logical_block_0_async_page/.
`smartctl -x /dev/sdb` may give you more information.

If the sectors were reallocated, like in
https://forums.debian.net/viewtopic.php?t=149547, then it would be
less of a concern. But yours seems to be a hard problem.

I better defer to some of the folks more experienced with disk problems.

This looks very relevant to your case:
https://askubuntu.com/q/1424120 It even discusses the Chinese
counterfeit hardware.

Indeed, it is very relevant to my case. lsusb reports:

Bus 003 Device 027: ID 048d:1234 Integrated Technology Express, Inc. Chipsbank CBM2199 Flash Drive

which is the same as mentioned in that site.

Sorry for wasting all your time.

Some time ago (I don't recall when), I had a thread in this list in which I wanted to know how to check if a USB drive has the claimed capacity.  I was directed to:

f3 ("https://fight-flash-fraud.readthedocs.io/en/stable/#")
and
f3probe ("https://fight-flash-fraud.readthedocs.io/en/stable/usage.html#id6").
f3probe is a part of f3, as is f3read and f3write.
f3 is available via dnf, if you don't already have it.

These might be useful for checking that the drive really has the capacity it claims to have.  I found them useful.

Beyond that, others in this list are much more qualified to help.

Thank you!

So, I got the folowing:

$ sudo f3probe --destructive --time-ops /dev/sde
 F3 probe 8.0

 This is free software; see the source for copying conditions.

      Reset: 0us / 0 = 0us

So, I guess this means that the USB is bad.

If you paid less than US$1000, then the only 2 options are: it is
stolen (pretty unlikely as they would still sell it for a high price)
or fake.

And if it is just a usb key device (not an external disk enclosure) it
must be fake because I don't think you can actually fit the memory
chips for 16tb in something that small.

So this is likely a much smaller usb device with firmware to make it
appear like a 16tb device.

Indeed, I got taken for a ride, thank you! I will ask for my money back, and see.

Just curious, what is the largest amount for which memory chips can currently fit in a USB? 1-2 TB? Or far less?

(I was not aware of all these complexities.)

Many thanks,
Ranjan

You will spot it like a boss next time :) How do you think we learned it?

I will only buy usb keys from newegg and I always make sure to pick
Sold by Newegg.  Newegg also has 3rd party sellers and they at one
time cleaned up the outright fraud larger USB devices.

The largest newegg carries(under sold by newegg) is 1tb with a
reliable brand name and those are $80-$150.  There is a 2tb one from a
brand I have not heard of at $140 but nothing larger than 2tb is being
sold.

So newegg is at least policing this outright fraud.  It appears that
amazon is now possibly policing this outright fraud (a few years ago
$30 1-2tb drives were all over both of them, all fake).

The samsung external usb ssd I like max out a 4TB.

Barry

[Roger Heflin]

That is a 2.5" right?   I think the one RanJan has is a 16tb usb key.

Commercial 2.5" ssd's go up to above 16tb+ but cost real money.  Ie
$3k+ for 16tb, and >$5k for 30tb.

What I am referring to is a USB-3 external SSD its 85 x 57 x 8.0mm
See https://www.samsung.com/uk/memory-storage/portable-ssd/portable-ssd-t7-1tb-g...

I have not looked at large internal SSD storage, only personally have 2TB at the moment. As you say I would expect 16TB to be very expensive and aimed at the enterprise market.
