Problem with disk space after new partition

[Leonard]

I have a wierd problem when I partition my HDD. Its a Quantum Fireball 30GB HDD. I have deleted all partition and created new Primary, Ext and Logical partition and formeted it with FAT32. During format it didnt find any BAD block or didnt generate any error. But When I see the partition from another OS (XP from another HDD), I foud 20-30% of my HDD space has taken from every partition. But I dont have any data in it. I tried with Partition magic 8 and Dos tool Fdisk. But got no result.

Please someone help me with this.

This is normal. The disk space seems missing because HD makers lie to you about the capacity of their disks and some room is needed for filesystem structures too. Some megabytes are also wasted sometimes because it is not possible to make partition boundaries everywhere and some megabytes go unused in between.
