It's possible to forego partitioning and put a filesystem directly on a disk. When you mount a block device, the filesystem driver typically looks for a superblock at a predetermined offset from the beginning of the device, and since the beginning of a partition is not the beginning of the disk itself, the superblock for a filesystem in a partition is located at a different place on the disk ...

2017年7月20日 · usually /dev/sda is the whole device, and /dev/sda1, /dev/sda2 ... are partitions which may contain filesystem. fsck works with filesystems, so running fsck on /dev/sda is usually meaningless - you will get an error, because there will be no filesystem to check.

2008年10月6日 · The livecd will probably show a mount point for sda1 as /mnt/sda1, and a mount point for sdb1 as /mnt/sdb1. Open a terminal window, and mount sda1 and sdb1. mount /dev/sda1 /mnt/sda1

2015年3月7日 · sda1 is the one I am concerned about, so that is the one I am posting below. Try this - start with the largest directory(s). You can use a similar command descending into the big guys (drop the -d 1 in the dirs)
