hello guys,
I just purchased a brand new maxtor 160Gb harddrive where I installed
fedora core 4 and the drive was fully recognized by anaconda during
installation as a 160Gb.
Installation went all ok but when I first logged in to my account and
checked the available space on disk i noticed that strangely the space
available was only 135Gb meaning that approx 30Gb were not counted in.
I then upgraded to kernel 2.6.13.1-1532.FC4 hoping to regain the
missing
space but still no sign of it.
I therefore installed QTPArted and checked what the situation was and
funny enough the LVM on qtparted is recognized as 160Gb.
I also have a 40Gb external HD connected via USB which is fully
recognized.
What has happened to the remaining 30GB on the MAxtor HD?
Most is probably the classic disk vendor kybye = 1000 bytes vs. everyone
else using 1024: http://personal-computer-tutor.com/abc3/v30/vic30.htm
and the rest is formatting overhead for the free space table and inodes.
And by the way, 160-135 isn't quite 30.
And the default root reserve.
Exactly. Do a "man mke2fs" and search for "reserved-blocks-percentage".
"-m reserved-blocks-percentage
Specify the percentage of the filesystem blocks reserved for the
super-user. This avoids fragmentation, and allows root-owned
daemons, such as syslogd(8), to continue to function correctly
after non-privileged processes are prevented from writing to the
filesystem. The default percentage is 5%."
