Disk Size only 495 GB?

[Sterke-Jerke]

I installed an external USB disk from WD that is supposed to be 1Tb.

This is what fdisk shows for the partition (seems wrong to me)
The number of cylinders for this disk is set to 121601.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/discs/disc4/part1: 1000.2 GB, 1000204853248 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Command (m for help):



This is what DF shows:

This is what fdisk -l gives me:

How can DF onlys hows 479Gb? Is this an OS limit? Should I split up my partitions?

Very strange indeed.
Which file system does that partition use?
Do you still know the command you used to format it?
Do you have a swap partition on that system?
What does 'mount' say?

I will redo the installation, and keep you posted

(And yes I have more then 512Mb swab)


PS: I think a 5% reserved blocks for journaling is a bit overkill for a 1Tb drive.
Any hints? 1% enough?
