Red Hat Bugzilla – Bug 427976
LaCie Desktop HDD, 500 GB, appears to be smaller
Last modified: 2008-04-27 00:19:42 EDT
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):
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.
A partition no larger than 46 GB is created.
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
That's weird. It is limiting the disk to the size of (sectors * heads)
Just to say that I've managed to create a partition of 460+ GB using Fedora's
