Wrong USB disk size

English Hardware
#1

I am running 64-bits Opensuse 10.3. I cannot get the PC to recognize the correct size of my external USB harddrive (LAcie Biggest Quaddra 3 Terabyte). If I start with the 64 bit windows partition it recognize the correct size (3 TB). I have data on it that I would like to access from Linux. I have a total of 12 disks in a raid system connected to it and it works fine (total size of 7,5 TB).

If I run fstab -l I get the following (it is sdc with size 2199 GB that is wrong, should be 3000 GB):

Firstly, it seems fdisk doesn’t like GPT type partition tables, perhaps view
the drives using gparted (you may need to install it)

The output seems to be limited to 32bit values. Likely a limitation of
fdisk. It does ask you to use gparted instead.

Hello!

I found this on internet:
“I first contacted LaCie. The office in Belgium --the country where I live-- gave me a patch for Windows XP/Vista that I had to install using Windows. After that, they recommended me to upgrade to at least a 2.6.24.xx kernel (I’m running Fedora Core 8). Both items made the Quadra 4T work for me using parted. So, it’s not really a problem related to parted, but rather to LaCie and the OS/kernel of linux that did not had the proper 64bit usb-storage module until kernel 2.6.24.xxx.”

I installed Opensuse 11 (64-bit) with kernel 2.6.25 and everything works fine and fdisk -l correctly shows the disk size. I fI connect the drive via firewire I got the same erratic size as befor. Maybe 64-bit firedriver is not good enough so far.
