Ubuntu 10.4 Hard Drive Missing

[pobri19]

Hi guys, I'm having trouble locating my second hard disk on my fresh Ubuntu 10.4 install.

It's a terabyte drive that I cannot seem to find in Ubuntu. It's formatted in NTFS and is over 90% full of data.

If I boot into Windows 7 the drive appears fine and the data is all there and Windows disk scan doesn't report any problems.

The drive: WDC WD10EADS-00L5B1 ATA Device (as listed on Windows 7)
Disk 1 (According to Windows 7)

Here is my fstab, fdisk and uname:


Linux nix 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux

# for a device; this may be used with UUID= as a more robust way to name

As you can see from the above, my other drive is detected fine (the one with the Windows installation and Ubuntu installation on it)

Any help would be greatly appreciated! Thanks.

EDIT: On a side not, I don't have a floppy drive installed, so I'm not sure why fd0 is listed (perhaps it's irrelevant - I'm new to the Linux world so I wouldn't know)

Short reply

Check your places menu on the panel

See if your second disk is listed

If not, you may have to install ntfs support.

PS: about the floopy, don't really know. but it's a noauto fstab entry.
On fstab your second disk partitions should look like /dev/sdbX (X being some integer). b, not a.

What do you mean by
"As you can see from the above, my other drive is detected fine (the one with the Windows installation and Ubuntu installation on it)"

"Disk 1 (According to Windows 7)"
This because Windows recognize Disk 0. your /dev/sda, right?

I can mount my Windows partition and view the files fine, and it's an NTFS partition, so would that not indicate NTFS support is working?

My second disk is not listed in Places menu.

And yes, Disk 0 would be the Windows disk.

Thanks.

Well, then what can I say? It seems ubuntu really don't see your second disk...

EDIT:
Sorry to ask, you seem fluent on linux
But are you sure you have two disks?

If unsure, post
$ lsscsi

(you may have to
$ sudo apt-get install lsscsi
)

Hence this thread >< It's detected in Windows, so it's obviously a Ubuntu problem.

Please see my edit

~$ sudo lsscsi
[8:0:0:0] cd/dvd HL-DT-ST BDDVDRW CH08LS10 2.00 /dev/sr0
[9:0:0:0] disk ATA WDC WD1001FALS-0 05.0 /dev/sda

Hmmmm This is really irritating.

And yeah I'm sure I have two disks, I just built this computer around a month ago :P

[ptkobe]

You said windows knows two disks (I should had consider that before)

The above says you only have one disk as far as linux concerns.

What may be different on that other disk? So that linux don't recognizes it? Doesn't ring any bell, sorry.

Linux sees it all

What are those HPFS/NTFS partitions on sda, btw?

Maybe someone else have an hint.

Regards
Luis

They're just storage partitions. One is the Windows operating system partition. The Ubuntu partition is on that disk as well. The disk wasn't detected when I installed it either, it could only see this Windows disk.

I've Googled my disk and other people have said they're using Ubuntu with it, so I don't understand what the problem is...

[ptkobe]

I'm thinking you may have a second disk that is bad connected.

Check if it appears on the bios

Tell me what you see of it on windows that you cant see on linux

sda is also a 1TB disk. You have 2 TB disks, right? As you posted
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes


PS: I also googled, saw nothing alike.

EDIT:
You don't have a linux swap partition?
