Description of problem:

I've tried to use a LaCie 500 GB HDD to perform some mirror-backup with dd

I've tried to obtain a single primary partition of 500 GB on the HDD, on both
Fedora 7 and Fedora 8.

The maximum size of the partition that can actually be obtained is around 46 GB
(/dev/sdb1). Here's the output of fdisk -l:

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot      Start         End      Blocks   Id  System
/dev/sdb1           1         60801   488384001   83  Linux

And here's the output of df -h (the relevant lines are the last two):

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2             265G  7,5G  244G   3% /
/dev/sda4             996M   34M  911M   4% /tmp
/dev/sda1             479M   23M  432M   5% /boot
tmpfs                1007M     0 1007M   0% /dev/shm
/dev/sdb1              46G  675M   43G   2% /media/IBM
/dev/sr0              197M  197M     0 100% /media/LaCie_Storage

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Connect USB HDD according to manual and power it on.
2. Using fdisk on the empty HDD, try to create a single primary partition of 500 GB.
3. Note that a partition no larger than 46 GB is created.
Actual results:
A partition no larger than 46 GB is created.

Expected results:
Partition should be as large as the HDD is.

It doesn't seem like a problem in fdisk(8). Did you try to use any other tool,
for example parted or sfdisk? Any error message, dmesg?

Did you try to create two partitions? What if you create a small sdb1 and a huge
sdb2? Is it possible?

It seems you are not alone with this problem, see for example
Comment 2 Chuck Ebbert 2008-01-10 15:41:46 EST
That's weird. It is limiting the disk to the size of (sectors * heads)
Comment 3 Răzvan Sandu 2008-01-10 16:00:22 EST

Just to say that I've managed to create a partition of 460+ GB using Fedora's
