I'm thinking of defraggers like Diskeeper and PerfectDisk as well as
XP's own defragger.
If there is a problem then their response is generally undefined.
There are a whole range of disk data integrity problems.
Some defraggers produce an error code for some problems
and will not try to defragment the drive.
At that point you fall back on MS$ product to see if it
can repair, or repair after a restart, which assumes that
the system will boot after the restart.
If it is a failing drive then you may be digging a bigger hole,
try to image, if that fails it may be a one shot
attempt to copy as much as you can. You try to
copy blocks of files, such as one folder at a time,
get an error unable to copy abc.xyz, delete the file
then carry on.
Of course for this you have to have a drive to copy to.
An eSATA or USB does not need a reboot, which may
save the day.
If the system drive is failing then you may not get
that far.
NTFS seems to be more robust than FAT and I've only
had a few data integrity problems, usually the drive
goes tits up without prior warning.
At which point you reach for your True Image (or
whichever you use) recovery disk and think about a
replacement drive.
You can of course create a file integrity problem
on a perfectly good drive, such as a dual boot attempt
going pearshaped, and you get the no system
message. Use image restore and have another go.
With tried and tested backups you are pretty fireproof,
and restore takes minutes. Rebuilding the system
and reinstalling all your software can take days,
and of course you have lost a lot of work, emails,
and vital stuff on the dead drive.
There are a few utilities that can seek to recover
seemingly lost or corrupt data.
He only asked if defraggers checked a volume prior to moving data. So,
yes/no will do.
Any defrag tools I have used since DOS 3.2 do a file system integrity
check, then give an error and stop the defrag if there's a problem.
The current one's I use are Diskeeper, and the XP and Vista
defragmenters. The error messages aren't very explicit, but a
chkdsk /f usually fixes any reported errors.
> He only asked if defraggers checked a volume prior to moving data. So,

OP generalised, there are many defraggers, I pointed out that
there is no consistency, either within any one of them, it
depends on the type of data integrety error, or between
how different defraggers handle the problem.
One I met compounded the problem, by seemingly
duplicating, without resolving, the corruption first.
There is no black and white, yes/no answer.
No defragger can cope with loss of data integrity on
a failing drive.
Defragging if of questionable value and the MS$ utility
does a fair job. Smart placement is just bells and
whistles.
Better to spend your money on backup than
defragging.
Yes, I believe they do. AFAIK, the windows defrag API developed jointly
by Diskeeper (excellent defragger BTW) and Microsoft has provisions for
checking the dirty bit on the volume before initiating a defrag. All
defraggers that use the API will utilize that. That's why some users get
a "Cannot defrag, chkdsk is scheduled to run etc" message when they
attempt to defrag a dirty file system. The defraggers themselves don't
run any chkdsk scans by default AFAIK, they just check the bit, though
some may have the option to do a full chkdsk before each defrag.
He didn't ask for defraggers to fix things.

You can only say yes or no for a specific defragger, but not
for defraggers as a generalisation.
> He didn't ask for defraggers to fix things.
If OP is not interested in fixing things the query has no
meaning. Concern about checking the volume implies
concern about data integrity.

As I said there is no yes/no answer.

So you are suggesting that we say that all defraggers
check the volume for integrity before defragging.
Commit yourself to yes or no, since you are so
concerned with an absolute definitive answer.

So tell us how smart placement makes jobs
run faster.
I have yet to see any improvement in processing
time for processor intensive jobs as a result
of Smart Placement.
Performance is more a hardware issue than where
the data is on the drive.

But some utilities make life easier.
And in order to backup you have to spend money
on one or more backup drives, or on optical
media. What makes you think you don't have
to spend money? Perhaps you are one of those
who relies on a recovery partition, then comes here
asking what do I do, my drive has failed.
No, I am not suggesting that.

I am saying that a defragger that goes beyond that MS bult in defraggers
don"t have to cost money.
Your problem is, that you can't read and that makes this discussion useless.
> >> Smart placement is just bells and

It is bells and whistles because it only benefits the
defragger by placing infrequently changed or accessed
files at the start of the drive, in non-fragmented
blocks. Where they do not get fragmented, so do
net repeatedly have to be defraged at each
defragmentation cycle.
The free MS utility does an adequate job.
System performance is a hardware issue,
Drive cache size, spin speed, access time,
pagefile optimisation, and a few other variables.
Try a few tests for yourself on drives that have
only been defraged with the MS utility, and
then on drives that have been detraged with
one of the cited utilities that has Smart Placement.

And is unlikely to yield any performance improvement,
stick with the MS one and invest in backup media.
Better use of your money.

Not so, the drive can more than adequately cope
with fragmentation. With adequate RAM drive
access is not an issue. Just check your
page faults with an MS defrag optimised drive
versus one with Smart Placement, no difference.
No difference either in Sandra benchmarks.

Free media?
Ah, so a drive copes with fragmentation itself?
> With adequate RAM drive

At one point a file has to be read from disk /written to disk. No matter the
amount of memory a fragmented file will take longer than an unfragmented
file placed near the start of the disk.

File fragmentation is not limited to paging. It is unclear to me what you're
trying to argue here. You're constantly mixing things up. See where you got
us from the simple question 'do defraggers check the file system' all the
way here.
Of course it has. He's possibly afraid a defragger may corrupt a file system
in inconsistent state. That's something entirely different than asking a
defragger to fix corruption.
> He's possibly afraid a defragger may corrupt a file system

There are defraggers that will further corrupt a file system
that is in an inconsistent state.
There is however no comparison checkbox for
defraggers. With ticks or crosses for various types
of corruption/inconsistency of the file system.
All should stop with an explanation if they find an
inconsistency, many don't.
I've seen defraggers that stop if the mirror MFT
is inconsistent, others ignore it.
Some try to move cross linked files, others stop.
Some duplicate orphaned files in the defrag
process, others ignore them.
So as I pointed out there is no yes/no answer
unless you are very specific about what defragger
you are referring to and what inconsistencies in
the file system you are concerned about.
The MS$ one catches most inconsistencies and
suggests a defrag/repair at the next reboot.
If it reports a repair log then it is adviseable
to check that the mirror MFT is consistent
with the master MFT, frequently, after MS$ has
done its repair these are inconsistent.
CHKDSK seems to have problems coping with
inconsistencies between the MFT and the
mirror MFT.
Which is why you need a proven and tested
backup system.

Wrong when its a media file and the access to the
file is entirely dependant on the media play speed.
Fragmentation is completely irrelevant to how long it takes to move thru the file.
Yes, so this finally answers OP's question.
It's more productive if you then try to explain to me what it is he's
saying.

Yes, and so?
O&O Defrag can be set to run a check of the filesystem before starting.

The drive has the MFT and its mirror, It knows wher the
requested data is, and will deliver files/data within the time
given in its spec. Drives are slow mechanical
devices as compared with the purely electronic parts of a
system.
Many assert that it is not worth defragging as it produces
no discernable improvement in system performance.
Much like registry cleaners.
Hello Joep. I'm the OP. I want to avoid making the data in my
partitons inaccessible by defragging if the defragger did not
ensure file system integrity before it started work.
FWIW I use PerfectDisk (it's now at v.10 but I use v.7).
Out of interest, does DiskTune do all the checking which Checkdsk
does? I know your website says "it checks the volume state prior
to defragmentation" but I wasn't sure if that was equivalent to
Diskchk. Thanks.
Sorry to have read your replies sooner. Thanks for the info. I
asumed a Checkdisk was always being performed whenever I used my
PerfectDisk but I wasn't sure. From what you say I shouldn't rely on
a defragger doing a check of file system integrity. Thanks.
Yes, it is bloody obvious it knows where the data is, that's the whole idea
isn't it? FYI, the MFT mirror isn't used for this and the mirror isn't what
it suggests it is (a complete mirror). What spec? Even if 'it' knows where
the data is, it still has to read it from the disk.

Yes.

Well, they're wrong. One could argue that the improvement ain't that big of
a deal, that's open for discussion.

Utterly different beasts.
That was that I figured.
> FWIW I use PerfectDisk (it's now at v.10 but I use v.7).
>

> does?
Nope. Orginally I did, check if dirty bit was set (using chkdsk), but I
figured that it was wiser to have chkdsk do the repair instead of suggesting
that it was DiskTune doing the fixing of the file system. Currently I only
check the dirty bit (I think thats what the Vista defragger does as well).
However, defragging using the defrag API is harmless even if file system is
dirty.
> What spec?
Drive mfrs give access time specs.

> the data is, it still has to read it from the disk.
Into its buffer. All that defragging does is ensure that it can
do this as a synchronous read.
If you want your data delivered faster buy a server drive
with high spin speed, a larger cache than consumer level
drives, and think SCSI or RAID striping.
Then get yourself an Intel Extreme Processor for
its larger on board cache.

Corse its correct.
And there are plenty of other examples where fragmention
has no effect on real world file use too, most obviously
with non serial access to files like with databases etc.
In fact there arent very many situations where the speed
of serial access to large files happens much anymore.
The most common situation now remaining is file copying
and it makes a lot more sense to not copy large files around
instead. Put them where they need to be in the first place.
Even with backup, the extra time that fragmentation can
produce is largely irrelevant because anyone with even
half a clue does backup in the background anyway.

Its also open for discussion just how much serial access to
large files there is on most desktop PCs that isnt media files
with which the speed of access is entirely determined by the
media speed, so fragments are completely invisible speed wise.

Aha, you quite sure you aint one of those rocket scientist fellas ?
Then define normal desktop PC use. People I know turn off the PC at the end
of the day, and then when they turn it back on next day they're annoyed by
the huge amount of time it takes to start up Windows. Remedy: optimize the
file system, it has a huge impact. Those pcs are typically used for all
kinds of stuff (databases not being one of them), browsing, email, text
processing etc.. Programs are closed, opened again etc.. All kinds of stuff
that can be improved by defragmentation and disk optimization. often, when
they ask for my help cause the thing is so slow, it's the only thing I do,
run disk optimization, and they notice the difference, even i something as
simple as listing a large folder in explorer. I suppose that there will be
differences between an up to date, fast modern machine and one that has been
running for a few years. And if you reboot the thing only once a week then
boot optimization won't be that big of a deal.

That is not due to fragmentation, it is due to the number of processes
and services to be started.
By your argument a heavily used machine would be so fragmented
and slowed down by it to be unuseable by lunchtime.
You are trying to convince everyone to defrag several times a day.
Fragmentation wasn't an issue in the days of CP/M and isn't
today. You don't have to defrag TB drives every few hours.

Nothing to do with normal file fragmentation, essentially because few of
the OS files get very fragmented because they arent written that much.

Like hell it does.
And the later versions of Win optimise the location of files on the hard drive anyway.

And very few of those do much serial access to large files except with media files.

Those files arent significantly fragmented on normal desktop PCs.

Easy to claim. Pity you cant actually substantiate that claim.

Thats the placebo effect. Have fun proving that with a proper double blind trial.

And fuck all of the boot time is due to file fragmentation.

Not with modern Win OSs that do file placement themselves.

Cant even manage its own lines. Or anything else either.
No, because if I optimize this file system it starts quicker. So I load the
same amount of services, change one parameter namely the location of the
files on the disk, and it loads faster.

No I am not. Biggest gain is from optimization (file placement) and I do
that every few months.

It still is an issue

I agree.
Hello Joep. I should say I'm sorry for being ambiguous for writing
"Checkdsk and "Diskchk" when I meant "Dskchk".
I have 2 questions.
(1) Is the XP dirty bit set by events like a Dskchk and when the
system encounters a problem in accessing data? If so then it must
mean the dirty bit is not set if the system is unaware of a problem.
(2) By a "dirty" file system do you mean (a) one in which the dirty
bit has been set or do you mean (b) one in which the file system is
corrupt and the dirty bit may or may not have been set? IYSWIM.
I'm trying to find my way forward to understand how using the defrag
APIs can be harmless even if the file system is compromised.

I have, defragging makes no discernable difference. It's
juat that a lot of people are making a lot of money out
of defragging utilities, and pretending to be experts to
make money as computer consultants and repairers.
Hospitals, universities, most businesses, don't
routinely defrag, and their computers run perfectly
well without it. Manual front office operations continuously
process orders, holiday bookings, customer queries and
help desk operations, they aren't defragging all the time
their systems run perfectly well without it.
If you want to permanently boost performance then
go through system services one by one, many
that start automatically aren't really needed and should
be stopped, or set to start "on use". Then go through
apps that start on boot, followed by reducing the startup
delay timers, like the one that waits to see if you want
to start in safe mode.
You are a Snake Oil peddler with your exagerated claims
of a dramatic performance boost.
Even LanParty and online gamers continuously
shifting screens of graphics and large volumes of
data don't keep defragging all the time.
I do not make money with it. I am not talking defragging, I am talking
optimizing for quite a few posts now. If you didn't get that by now, you're
thick. It does make a noticable difference (file placement, optimization).
Right here, on both PCs I use. What you have to say for the rest, I don't
care. If you defrag or not, I don't care.Iif anyone else defrags or not, I
don't care. I am not in a server environment, I don't care if they run it on
servers or not.
Waiting for the thing to boot bugs me. If I can bring that down even a
couple of seconds (but it's more than that) then for me that's significant
and worth it. I tested that and I do not need you or Rodless to confirm
that. To accomplish that I do not need to defrag 'all the time' as you put
it. Just once every 3 months is fine depending on software installed
(including service packs) during that period.
All apps I frequently use load faster after disk optimization. Instead of
the previous disk rattling and waiting, the disk is now quiet and the app is
up in no time. For me that's a significant improvement. I am happy now.

Did that, you lied.
And it makes no sense to be doing a full reboot every day anyway.
If you do want to turn the system off every day, you should hibernate, not shut down.

Like hell it does. And modern MS OSs do that anyway.

Doesnt make the HUGE DIFFERENCE you lied about previously.
Even with the worst file placement, the most that does is add
a couple of milliseconds to the head movement between files
and that is nothing in the total boot time of a curent MS OS.

Pity you're so stupid that you havent even noticed that hibernating saves
a hell of a lot MORE in the startup time than file placement ever does.

Service packs dont come out at anything like that frequency and
software installed doesnt affect the placement of OS files either.

At most by a few mS. Thats nothing in app start time, liar.

Nope, the mS or so saved is nothing in the time it takes to load that file.

Try it and you will find you're wrong. You can continue repeating yourself,

Yeah, I meant the regular updates, sorry. No, software installed doesn't
affect OC boot, but if those are programs I frequently use, I want them
optimized as well.

Well, it actually does Rod. Loading an app does may require Windows more

What does hibernate do for app loading then?

Then you are a terminal fuckwit when hibernating saves a hell

Yep, even you should be able to see that there is no mention of optimising

Dont need to. Even someone as stupid as you should be able to
work out that the extra time for the longer seek with a poorly placed
file can never be more than a few mS with modern hard drives.

Just another of your lies.

They can indeed, and proof that you are a pathological liar.
Not that that is any news to anyone at all.

Still fuck all with each file.
Hibernating saves FAR more time.

Hey, Rod, do you think "Joep" knows what ever happened to his
fellow denizen of the Netherlands...the foulest of fanatics,
Folkert Rienstra? Dat ol' Folksy ain't been around here, at
all, throughout 2009.
In fact, according to Google Groups </http://groups.google.com>,
the dreadful Dutchman's final Usenet post was on September 19,
2008; no longer does he plague >any< newsgroup, evidently.
Oh, and for your information, I'm hardly wailing about his
sudden disappearance. (Good riddance to bad rubbish, as the
saying goes.)

He's the one that killed him off, because Fucknert
made snide remarks about his commercial activity.

Yeah, the GFC saw the plug pulled on net access to his padded cell.
Heard the one about silver linings ?

Indeed.
