If you remember well, I said I formatted the drive by right clicking

you don't have a partition, the drive can't be used.
You can format a drive without a partition table, and still
format/use it. I am not sure if it would get automatically mounted,
but it does work. A partition table, and partition will NOT be
created for you. Also, you can have a drive with one partition
without that partition being partition 1. ZIP disks were famous for
this. For a log time, DOS formatted ZIP disks used partition 4.
The man page does say:
e2fsck - check a Linux ext2/ext3/ext4 file system
A file system is not a device. So, the filesystem -- here sdb1 -- must
be specified.
Note: I answered Bill Davidsen first.
You
can use an entire drive, or a partition on a drive, as a tar
archive. (tar -cvf /dev/sdb /home/mikkel)
Then, I have no idea where the /sdb1 partition comes from. I also have
a lost and found directory on that drive.
A thumb drive comes with a single partition, and reformatting that partition as
ext3 still leaves the partition table intact. The operative word in what I wrote
is "can" do it either way, what you have is fine, but if you had no partitions
that wouldn't mean that the drive was unusable.
Since the mount point is "BK" it's likely that somehow you used that as a label
for putting the ext filesystem on the partition.
As for using the whole drive to hold a tar:
tar cf /dev/sda /home
works, although
tar cf - /home | gzip -8 >/dev/sda
lets you put more on the media. I would not guess if the CPU time to compress is
more or less than the write time for the uncompressed data.
Since you have room for everything, I would suggest that rsync is a good
solution, it will back up only what changes. Archives are nice but you are
likely to want to pull an individual file out from time to time.
Here's an ls:
ls -al /media/BK/
