Hi,
i have 2 hdd of 500G on which i have partitions of 472G, using which i have created a RAID 1.
now when i try to use the disk i only get a usable size of 440G
here is output of 2 commands which may be of help
uname -a

Disk /dev/md5: 472.6 GB, 472575233024 bytes
2 heads, 4 sectors/track, 115374812 cylinders, total 922998502 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
i initially thought it may have been due to ext3 file system keeping aside 5% for lost&found but this is giving completely different picture and i am now confused. even if i assume that it is some cylinder*sector calc or something, its not adding up to a logically satisfiable number.
