Is this true? The more activity, the more wear, just like the more you use your bicycle the more likely the chain will break. So, do you not use your hard disk at all between these defrags? You power up, do a defrag, and then power down until the next time you defrag?

Is this true? There is a small risk of damaging your file system while defragging, e.g. when you suffer a power failure right in the middle. I think defragging once a month is plenty. Any more often would make no measurable difference but would increase the risk.

Guest Colin Barnhorst Posted May 17, 2008 Posted May 17, 2008 Re: Disk Defrag It is not so much that you're running defrag as it is disk usage. Anything that heavily accesses the disk can eventually cause wear and tear on the mechanisms sufficiently to shorten disk drive life (even if slightly) when run excessively. You can get the same effect by constantly running chkdks or other disk utilities far more often than needed. But don't let that slight concern prevent you from running defrag appropriately (when the defrag analyser says you should defrag). These are reasons why folks should maintain a good backup plan. Hard drives do eventually just wear out even when using best practices. I have some that have lasted many years and I have had some that only made it a year.

Like begging the question as to how much shorter is the MTBF if there is less physical RAM so more pagefile space must be used. I know of users that like to use the flash memory thumb drives for pagefile space not realizing how often the pagefile gets used. Flash memory does wear out due to oxide stress. There is logic available on the drive to mask out bad areas but eventually the reserve gets used up and the thumb drive suddenly and catastrophically dies taking the pagefile with it and any changes saved there during the current Windows session.

I believe the use of journaling with NTFS compensates for that loss, and also if the content of the hard disk's PCB write buffers aren't flushed to the platters, too. Another reason to use NTFS rather than FAT. NTFS can use its journal log to determine how to return the disk to a consistent state upon recovery.

It appears to work most of the time but once every so often we get a post in this newsgroup that reports a thrashed filing system after an interrupted defrag.

Right. We just had a discussion on that in the other group, and how the flash memory lifetime is limited to begin with, and running defrag on it can significantly reduce its lifetime. (Someone mentioned a figure of only 1000 erase/writes for each cell, but that the overall memory lifetime, from a user's standpoint, is increased (by the chip logic you mentioned), so that the end result is the average lifetime figure is more like 10,000 - 100,000 erase/write cycles.

Which indicates the journaling actually failed? Wow. Well, maybe its not all that unexpected. Admitedly the overhead of NTFS has it advantages here, over FAT. I'll have to concede that. :-)
Guest Unknown Posted May 17, 2008 Posted May 17, 2008 Re: Disk Defrag I would venture to say there is much more wear and tear on a fragmented file if you don't defrag.

Guest Colin Barnhorst Posted May 17, 2008 Posted May 17, 2008 Re: Disk Defrag Yes.

Guest db.·.. > Posted May 17, 2008 Posted May 17, 2008 Re: Disk Defrag there is one thing you should keep in mind and that is if your disk is pretty filled up with data and you have very low disk space, then there is a lot of burden on the hard drive. but if you have lots of harddisk space, then run the defrag as much as your little heart desires. eventually you will come to realize that defragging takes time and is not always needed especially with large capacity disks. -- db·´¯`·...¸><)))º> "rick s" <ricks@discussions.microsoft.com> wrote in message news:4C4390A7-08CB-4E70-9695-FF9880DA1801@microsoft.com... > Someone told me that the more you run disk defrg the better chance of > destroying your hard drive.

Aevin Posted May 19, 2008 Posted May 19, 2008 Re: Disk Defrag The MS XP defragger actually tells you to defrag if the MFT and PF are fragmented, but there's nothing it can do to defragment those regardless of number of passes it makes. But it recognizes that those files are 'important' and their fragmentation will reduce performance. That's where Diskeeper steps in- it has the ability to defrag both the files, among a host of other features. > That is one of the nice things about some of the third-party > defraggers like Diskeeper and PerfectDisk.

Guest Gerry Posted May 19, 2008 Posted May 19, 2008 Re: Disk Defrag Twayne That's why you should ignore "MS's defrag will tell you it's not needed." You should select View Report and look at the real situation. However, it's not just a matter of frequently accessed files. You will normally not need to access System Restore restore points but if left fragmented their size, will on a disk with limited free disk space, cause fragmentation of other files, which are in active use. It's questionable whether you want any Norton product on your computer. Perfect Disk is I suspect more highly rated but there is really no need to pay for a third party defragmenter. -- Hope this helps.

Guest Twayne Posted May 19, 2008 Posted May 19, 2008 Re: Disk Defrag > Twayne I am Twayne: I did not write what's below. It is misquoted by someone apparently ignorant of such things. Since the dummy trying to pose as me knows so much, I wonder why he didn't post a solution? 3rd party apps are the easiest, but it CAN be done without them by basically turning off/moving the PF, starting in Safe Mode, and defrag the hard drive, then turn the page file back on and set it up. Once the files are defragged and contiguous, then the PF will have to be the same and will be the same; contiguous. Caveat: If you're not familiar with how to do this effectively and moving the swap file around, don't do it; you'll have less than satisfactory results. Better to use a trusted 3rd party app. HTH Twayne, the real one. > > That's why you should ignore "MS's defrag will tell you it's not > needed." Untrue: MS's defrag will indeed tell you a defrag is needed, when it is needed and is causing too many waits during accesses. You should select View Report and look at the real situation. Yes, assuming you're talking about Defrag's report. BUT, you will still need to be experienced enough to know whether the fragmented files are a problem yet or not. Depding on what I'm doing, I defrag monthly. But, if I'm doing something that creates zillions of temporary files such as design work, or especially video editing and rendering, I do so more often. Video work in fact requires a defrag every day, sometimes more often, depending on what's going on with any particular drive. Those are good reasons to keep a separate working partition for design/video etc. types of work; they defrag faster and don't mess with the boot drive much. It's a matter of learning your machine and experience, mostly. > However, it's not just a matter of frequently accessed files.

Existing Restore Points will have zero impact on fragmentation. Fragmentation only happens when data is written TO the drive. The total space used for restore points, although excessive IMO, is limited and they do not grow uncontrollably. > > It's questionable whether you want any Norton product on your > computer.

It's none of your business to comment on what anyone else had decided to use on their computers. I'm sure I could say the same about some of the apps you use too, but even if the opportunity arose and you asked for assistance, I wouldn't tell you to trash it unless it was actually rogue or malicious somehow. Norton, BTW, has an excellent ability to open up the area where a PF wants to live, and makes it easy to create a continguous PF. Norton's defrag app is also far form the only feature provided by their software package; in fact, it's a small part of it. Symantec's Norton Ghost is pretty decent as is their firewall app. But you don't know that because you allowed Norton to slow down your computer by bad setups and probably have no idea what it's capable of. That's fine with me. The only app I'm using right now is Ghost, but it's a great app with True Image running a very close second. But you won't know that either because of your parrot/misattribution mentality. Learn to quote properly. Flame away; I won't be wasting ether on you for awhile to come. > > > Twayne wrote: >>> That is one of the nice things about some of the third-party >>> defraggers like Diskeeper and PerfectDisk.
