Why would PM8 move files when more space was added at the end of the partition?

Why would PM8 move files when more space was added at the end of the
partition?

I used Partition Magic 8 to take unallacoated space in FRONT of an XP
partition and make the partition larger. There was another 40gigs in
front of the unallacated space, used by a win98 partition and a data
partition. After the partition was created, I was surprised to see
PM8 spending time moving files to the newly added space, but figured
PM8 thought it was good to have files at the start of the partition.

Yesterday on another computer, I used PM8 to take unallocated space
that FOLLOWED the partition and make an XP partition larger. The
partition was already 90% empty, but I was planning to add a lot of
stuff to it. Again it spent time moving files, I presume to the newly
added space. It took a half hour, maybe more (I went to the kitchen
to have dinner,)

Why would it move files when more space was added at the END of the
partition?

Thanks.

Might have just been filesystem implementation or faked/unnecessary
activity to give you the impression that it was doing something
complicated for marketing reasons.

Because its ****ed by design.

Presumably because that special case isnt treated as a special case and it just
mindlessly moves files around even when it makes no sense to do that in that case.

I thought PM8 was the leader in the field at the time and didn't have
to do things like that for marketing reasons. Not only that, if it
really wasted a half-hour of my time, that's a reason not to buy it,
nad not to use it even if I had it. But see what happened next.

Thanks Arno and Rod,

So tonight on a different computer, I enlarged a data partition, which
had 28 gigs of data in a 29 gig partition, by taking almost 6 gigs of
unallocated space adjacent to the end of the partition.

It has no OS at all, and I used Easeus Partition Master to enlarge it,
not PM8.

It only took a few seconds to set it up, and then it rebooted,
bringing up a dos-level graphic box on restart, and AGAIN, it too
moved data around. It took four minutes/1% for the first couple
percent, then 3, then 2 minutes and by 20% it was going much more
quickly. Took 29 minutes altogther.

I forgot to look it right away, and I copied half a gig into the
partition before I remembered to use XP Defrag to see where the files
were, but when I looked, the entire added 6 gigs was full of
contiguous files** Norton SpeedDisk shows the same thing (although it
didn't say if they wree contiguous or not) and for some reason it
labels some of them unmoveable, even though I don't think any are.
They are all downloaded files or data files created by programs I use,
mostly Agent and Eudora and from my camera, and IRS forms, etc.

So why would Easeus PM also move files to the end when more space was
added at the END of the data-only partition?

If they both do it, does that mean there's a good reason. Perhaps
the HDD will vibrate if all the electrons are at the start of the
partition?




**(at least it appeared that way. Some variations could be there that
are too hard to see in the one horizontal bar, but I suspect not.)

Just the best known.

Yeah, thats just another utterly silly conspiracy theory.

Yeah, specially if a competitors system didnt have that stupidity.

But see what happened next.

Dunno.

Cant think of one. See what Acronis Disk Director Suite does in that situation.

Nar, cant be that, thats the config some defraggers produce on a defrag.

And this is no laughing matter.

It was the only thing in the field for a long time. It was never
really good, with a high chance of filesystem corruption when doing
several steps at once. I used it several times and then found out
that backup, repatitioning and restore actually saves time in
quite a few cases.

Today I use the (free) gparted, which is in many ways better.
And gparted has not corrupted anything for me yet.

Pretty strange. My experience with gparted is that enlarging at the
end basically takes no time at all. Maybe they do the same thing
as PM?

It could also mean that Easeus bought its code from PM. I am not
aware of any good reason for moving any data when enlarging at the
end and I do not recall gparted ever doing it.

**(at least it appeared that way. Some variations could be there that

Well, IMO PM has sucked badly at least since 10 years ago (did not
use it before) and maybe the competition either uses the same code
or tries to emulate PM closely.

By now I have used gparted sucessfully even on NTFS partitions,
so I would recomment trying that, There are boot-CD versions with
a mini-Linux. It does not run under Windows.

Take note though that even with gparted doing a backup before any
partition mangeling is mandatory if you value your data.

This is my take. The file control blocks are in the front and when you
make the partition larger it needs more space for the file control
blocks. So files are to be moved to create that space at front and it
does take a lot of time to move the files when you have a gigs of
files.

blocks.

Well that makes sense up to here.

So files are to be moved to create that space at front and it
does take a lot of time to move the files when you have a gigs of
files.

And it makes sense that it takes a half hour to move 5+ gigs. In fact
I could easily be wrong but that seems pretty fast.

But... Why does it have to move a full 5 or 6 gigs to make room for
the file control blocks for 5 or 6 gigs?

Nope, not with a normal hard drive it doesnt.

You could indeed.

but that seems pretty fast.

Nope, even USB2 can do much better than that.

It obviously doesnt. And it doesnt need to move the files into the end of the drive either.
