The disk "/dev/sdf" has a size of 290GB, that part should be obvious.

The other disk "/dev/sdh" was not yet partitioned. A disk drive has to be written with some low-level information prior to be used by an operating system. This is the "partitioning" first, which divides the disk in one or more logical "disks" - partitions. Only after partitioning these logical disks can be used to store filesystems on them. Storing the file system information is called "formatting".

Think of a disk like a bare storage room: to actually store something in it you first have to build some shelves, on which to store the goods you want to store, probably prepare a list where you can enter all the things you stored and the place they are at to find them again, etc.. Formatting is like building these shelves and the list. It is preparing the storage room for actually storing goods there.

I hope this helps.

NAME
repartition - load a partition table SYNOPSIS
repartition device [partition-file] DESCRIPTION
Repartition uploads a new partition table for the partitions of device. The table is obtained from the first sector of partition-file if given, device otherwise. Device may refer to the whole drive or a primary partition, depending on whether you want to upload a partition or a subpartition table. The partitions will be truncated to fit within the enclosing device like the disk driver does, unless the numbers are coming from partition-file. EXAMPLES
repartition /dev/hd0 repartition /dev/hd4 /etc/hd4.table Reload the partition table of drive 0 setting /dev/hd[1-4], and the subpartition table of /dev/hd4 setting /dev/hd4[a-d] using a file. The latter may be useful if you need more than the 4 subpartitions a single Minix partition gives you. DIAGNOSTICS
The new table is printed on standard output. FILES
/dev/hd[0-9] SEE ALSO
hd(4), part(8). BUGS
The disk must be in use for the changes to stick. The partition table of an idle disk will be reloaded on the first open. AUTHOR
