[gentoo-user] Fdisk reports new HD as 10MiB

[gentoo-user] Fdisk reports new HD as 10MiB

[Robin Atwood]

I just bought a new "2TB" Western Digital hard drive. Imagine my
surprise when fdisk reports it is only 10MiB in capacity! Is there
anything I can do to rectify this (of a technical nature)? I live in
Bangkok so it is not unlikely the guy in the little shop where I bought
it sold me a load of junk. But the device is in warranty until 2022
and looks convincing (I checked the serial number on the WD web
site). Of course I can go to the WD service centre and get the HD
exchanged but I thought I would see if there were any technical
wheezes first.   

Thanks
Robin

Fdisk can not work with drives larger than 2TB. Your drive may be slightly
(10 mb) larger than that, so the result. For such disks you need not Fdisk,
but GPT programs.

Thanks Vladimir, that sounds promising. Can you recommend any GPT
programs (this is new to me)? However the dd utility failed when I
tried to copy my old HD to the new one. 

# dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync  
dd: error writing '/dev/sdb': No space left on device
160+0 records in
159+0 records out
10481664 bytes (10 MB, 10 MiB) copied, 0.132944 s, 78.8 MB/s

Well, dd should work well in any case. May be your drive is broken really?

You can use gptfdisk, parted/gparted, etc.

To check the size as well as additional information you can use smartmontools 
and run:

smartctl -i /dev/sda

It may also be worth checking if later firmware is available to address any 
issues with it, like reporting the wrong size with some tools.

However, the dd command failure sounds suspicious - as I understand it dd 
should not fail unless the disk has run out of space.

May be your motherboard or BIOS just too old, and it doesn't support such
hard disks?

OK panic over! I had shelled into the wrong system! The mystery is what
I was trying to copy to, the machine only has one HD.

I remember a time when Linux would support large (multi-GB) drives when 
the BIOS would not support them.

Linux could bypass the BIOS and talk directly to the drives and utilize 
the drive's full capacity.

The idea that Linux can no longer do this with larger drives disheartens me.

It would probably just have created a normal file called /dev/sdb which would 
have grown till it filled the empty space on the partition.

Yes, that's what it did, though it didn't fill the partition up. Phew,
that's a relief, I was worrying I had overwritten the BIOS or
something!

What about lsdrv (as per the raid wiki)?

That handles pretty much everything.

Recommend any gpt programs? fdisk :-) ?

Yes I know it was said it doesn't work, but ime it's been upgraded to 
cope. That said, I always use gdisk now, which is almost the same but 
explicitly handles gpt.

I've used cgdisk myself.  Mostly because I started out using cfdisk for
smaller drives and then when large drives came along, cgdisk was
available.  Both work the same way so no learning curve. 

Just another option to consider I guess.

lsdrv looks like lsblk, it's just that it handles afaik pretty much
everything - starts with the disk, then lists any partitions, any lvm's,
any raids, etc etc.

So if one has RAID software installed, there is a even better tool

What does lsdrv have that lsblk is missing?

lsblk is part of util-linux so its everywhere, which is handy.

Looking at "man lsblk", lsdrv seems to just print out a bit more info.
It certainly chucks out a lot more info on the raid setup, and I suspect
on the lvm setup too.

Be nice if lsdrv/lsblk came together to print out detailed info on
everything :-)

Correction: modern fdisk provided by util-linux supports
creating/modifying GPT disks, and emits a warning that MBR cannot be
used for disks over 2 TB. Just enter a "g" to switch to GPT mode.

That looks something like this:

% truncate -s 3T foo.img
