use the demsg to find the partition number # dmesg | grep sda . [ 7.340000] sda3: <openbsd: sda12 sda13 sda14 sda15 > . mount those 12,.. using mount cmd #mount /dev/sda12 /mnt/openbsd/12 -t...
That depends on the file system being used. Linux doesn't have just one file system.But various features you'll often find in a filesystem include inode tables, journals, redundant superblocks,...
The Linux kernel supports several file systems "natively," ie. in kernel mode not user mode. ext2/3/4 are the most common. but ReiserFS, XFS, brtfs, FAT, and several more are available.
For the purpose of this question, I'll stick to file systems that Linux natively supports and can boot off of. FAT12 FAT16 FAT32 X-FAT (used on the Xbox) Minix ext ext2 ext3 ReiserFS Reiser4 JFS XFS
