fdisk: What do plus signs after "Blocks" mean?

Hi there,
Fdisk on my machine displays the output shown below. Many partitions
have pluses after "Blocks". The issue is that during installation on
the existing linux setup WinXP screwed up the partition table, and
these pluses were very difficult to recreate. Basically, if I remove
hda9, and then try to recreate it in fdisk, it loses the plus sign and
does not look as before. Also, sometimes fdisk creates a partition with
"+", and sometimes it does not.
Since I did not want to take any chances, I used Knoppix to read a
similar partition table from /dev/hdb using "sfdisk -dx", and then
copied it to /dev/hda by using "sfdisk -fx". If I do not force sfdisk
by using "-f", it complains that there are some inconsistencies.
Can anyone enlighten me what the pluses mean? Also, if a partition
loses pluses after "Blocks", would that destroy a RAID array?
Thanks!
Konstantin
