Loss of 15gb after formatting LaCie D2 120GB drive Redhat 8
Posted on 2003-03-29
Hi, I have installed a LaCie 120gb D2 drive under firewire on RedHat 8.
When the drive is fired up on startup, dmesg reports:
SCSI device sda: 234441648 512-byte hdwr sectors (120034 MB)
But, after formatting the drive using fdisk and mke2fs, when I mount the
drive, df reports:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda 115380224 20 109519164 1% /data
If a 120gb drive has 128849018880 bytes (120 * 1073741824)
it seems to me that I've lost nearly 10gb on this drive after formatting
(115380224 blocks = 118149349376 bytes which is 110.04gb).
fdisk /dev/sda displays the following when printing the table:
Disk /dev/sda: 255 heads, 63 sectors, 14593 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 14593 117218241 83 Linux
All this doesn't make sense to me... are my calculations wrong?
Also, when I share the mounted drive on samba, and connect
to it on my mac, the mac reports that the drive only have 104gb
remaining, which is even worse....
Is this just a case of invalid calculations/reporting or have I
really lost between 10 and 16 gb of space after mounting?
