[Bug 596693] [NEW] Lucid does not recognise full size of large hard disks

Sun Jun 20 22:24:35 UTC 2010

Public bug reported:

I have an external 4GB disk, which is not recognised properly by Ubuntu
Lucid. This disk is a raid enclosure (USB + Firewire) made of 2 x 2TB
drives. When I plug it in, dmesg shows the following output:

---begin---
[242260.170103] usb 1-3: new high speed USB device using ehci_hcd and address 8
[242260.323887] usb 1-3: configuration #1 chosen from 1 choice

[242265.361940] sd 8:0:0:0: [sdb] Attached SCSI disk

---end---

Fdisk sees the drive as 2.2TB instead of 4TB:

---begin---
Command (m for help): p

Disk /dev/sdb: 2199.0 GB, 2199023255552 bytes
255 heads, 63 sectors/track, 267349 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1      267350  2147483647   ee  GPT
---end---

Gparted shows the same behaviour.

Same behaviour happens regardless of plugging it in using a usb or a
firewire cable.

Now, when I reboot the laptop into Windows and plug the disk in, it
works perfectly well. The windows disk manager sees it as 4TB drive with
2 MAC partitions and using MacDrive I can use the disk. I can also
access this disk from my macbook pro laptop.

Thanks
