Drive Space Help

[tntcoder]

Hi,

Just got a 1TB drive, and formatted it with ext3 and it comes in at 878gb of available space... I have heard of people getting about 930gbish once formatted in winblows?

Im guessing its the ext3 journaling information, but even with ext2 there is little difference?

Any ideas on if the file system can be tuned at all to give more that 878gb of space?

This is the empty clean formatted partition (max drive size) information:

Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1      121601   976760001   83  Linux

[root@thome mnt]# df -hT
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sdb1     ext3    925G  200M  878G   1% /mnt/tb

Thanks,
Jack

there are 931 'base 2'GB, and 1000 'base 10'GB on a 1TB drive - ie you are right, you should get 931 in a partitioner. I have no idea where the rest has gone - bad sectors maybe?

It seems the ext file systems reserve 5% by default for stuff...

Fixed it with this by reducing to 0% which gives 924gb, good enough i guess

tune2fs -m 0 /dev/sdb1
