Proper partition alignment is important for good disk performance. It is not
usually an issue when partitions are created on a clean disk. However, there
are circumstances under which it can be an issue. E.G., if a partition is
converted from FAT to NTFS, and depending on the parameters chosen, a
partition is created which crosses a boundary. The result is that a file
might be allocated storage on space that is divided by the boundary. The
result is an increase in the overhead for each read or write operation.

Also, proper choices are important when creating data structures on
solid-state disks.

This is probably not the place for a an extended, deep discussion of
underlying concepts and methods. So let me refer you to something to give
you a taste of one dimension of the topic

Very interesting, however, I found nothing in the links to indicate that not
using Partition boundaries could consume 10GB of disk space on a 160GB disk
with either XP or Vista and it appears that with a newly formatted NTFS disk
in Win7 and also possibly in Vista would have a problem.
I did learn that starting a partition not on a boundary could cause
performance problems in XP and also possibly in Vsita.

I am not surprised. I neither intended to nor did I address that. If I had,
I would have threaded to the OP. My only interest was, "Also I have never
heard of "Aligning Partitions" before nor could I find any information
about it using Bing".

Sorry to have caused you any confusion.

Wrong impression to be under.

You keep saying 10 GB. The O/P is talking about 10 MB

I see drives every day on which there are 7-10 MB of unallocated space at
the beginning of a partitioned drive.

He's says 10MB. That is a typical amount "left over" after formatting most
drives and is due to the way formatting works. Many users wonder about it
and I have seen the question many times. I think he really meant MBs.

You can't. It is normal and is right in line with my experience with
formatted drives. The manufacturer always provides "extra" sectors to allow
for bad sectors detected later by the disk manager in your OS as well as
partition alignment as commented on by Rick Rogers above. It is roughly
analogous to the margins used by a printer. The disk manager can "borrow"
sectors from the unallocated area if it has to mark any allocated sectors as
"bad."

Ok.

Thanks,
James
