    SP2 And Defrag (XP Pro SP2)

    I'm going to post a link to this thread in the Software Forum since I don't know if my problem is caused by XP or PerfectDisk Defragger. Not too long ago I finally got around to installing SP2 and all other updates to this machine. Haven't had any problems due to that install that I can tell, except for this one. I've run Raxco's PerfectDisk defragger for some time and I have an overnight, scheduled defrag routine setup for several of my partitions. Up until SP2, that procedure has run in very short order without excessive time being spent on any one partition. Since I installed SP2 however, the defrag has spent long periods on my BOOT drive, sometimes lasting as long as two or three hours on a defrag process that used to take only minutes. Since the defrag is done EVERY night, I can't fathom a reason for this sudden long delay, unless PerfectDisk or SP2 don't "like" each other. My question is have other users of PerfectDisk experienced this kind of problem, post-SP2 updating?

    BigAl,

    I've looked at the PD logs and have not seen any excessive run times since 12/1/04. Are you running 7.0 build 34? Can you tell anything from a manual anaylsis? Are you sure there is no other scheduled process running at that time?

    Re: SP2 And Defrag (XP Pro SP2)

    Hi Al !

    I'm running XP SP2 patched up to and including the latest release and just ran a complete system defrag with Perfect Disk this AM, including an Offline defrag of the Boot sector. Nothing out of the ordinary that I've noticed.

    Try changing the settings or shutting off the process for a day and then starting it up again. Might give it the kick in the head it needs <img src=/S/bash.gif border=0 alt=bash width=35 height=39> to get it's act together. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    Re: SP2 And Defrag (XP Pro SP2)

    Thanks for the responses, Joe and Doc. If you guys aren't having any trouble, I guess I need to keep digging. I am running version 7, build 34 and up until 2/5/05 the nightly defrag took only minutes on FIVE partitions. On the next day the C: drive started taking hours. This morning's run was two and a half hours. I did run a boot-time scan and it ran pretty quickly, so there IS either something going on at the run time or there may be a file it struggles with that's "live." I need to run a manual defrag and see how long that takes. I only have a file-backup scheduled for 2 AM (maybe 5 or 10 minutes) and the defrag was set for 4 AM. I changed the time of defrag to 3 AM but it still took that long time. I'll be back...

    Re: SP2 And Defrag (XP Pro SP2)

    I just completed running a manual defrag of the C: drive and it ran in 27 minutes which darkens the puzzle! That's pretty close to the "old" times when the log says it used to run in 15-20 minutes every night. I do always use PD's "Smart Placement" which is recommended and haven't changed that. So, it's pretty obvious that there's something going on during the SCHEDULED run that's slowing this baby down considerably. The only things I usually leave running during the night are my Palm Desktop calendar, which should be sitting idle and I've always had it on, and MailWasher which DOES check the email server every 10 minutes and it has always been running. Of course, in the tray I have my firewall, AV and a few other items active, but they too have always been there.

    The manual defrag, looking at the status bar in the lower left corner, went screaming all the way up to 57% and then it started to stall a bit on some "new" stuff like my recently installed PC-cillin 2005 (AV only) and the Windows directory for Service Pack Files. After awhile however, it resumed its faster speed and the overall time of 27 minutes ain't too bad. I noticed in the log that it's scanning some 64,000 files when that number used to be down at just under 61,000 - but I wouldn't think that's the cause, unless there's service pack junk that needs to be eliminated. The partition is setup as 12 Gig and 3 Gig is currently the free space. Again, based on these manual results I don't think lack of free space is the problem. I guess I'm gonna change the time of the scheduled run to something when I'm able to watch the Task Manager to see if I can spot anything.

    Thanks for hangin' in there with me...

    Re: SP2 And Defrag (XP Pro SP2)

    Just a quick thought.... could your system be downloading updates (Windows or others) overnight for you to peruse and install at your convenience after they have been downloaded ?? I know that any system activity during a defrag will slow or stop the defrag process.

    Re: SP2 And Defrag (XP Pro SP2)

    It's a good thought, Doc, and I don't (yet) know the answer. I don't have anything automatic from MS, as I always do that manually. I do have a PC-cillin AV scan of only my C: drive scheduled each night at 11:30 and that normally completes in 30 minutes or less. However, it DOES leave a screen open that reports (no) viruses found and I have to click to close it when I get up in the AM. It's been there all this time and hasn't caused a problem, but the update to TrendMicro 2005 could have changed things. It could be that it's causing a problem and I'll be able to hopefully check that if I change the defrag "schedule" to a daytime hour.

    Al,
    Have you installed the MS Anti-Spyware Beta? It has a default daily scheduled scan at 2:00 AM.

    Re: SP2 And Defrag (XP Pro SP2)

    Nope, not me Joe. It's a little too flaky for my tastes at this time. This may be something I just have to live with, I don't know. In case anyone is interested, I'm attaching a TEXT file with some data on yesterday morning's MANUAL defrag, this morning's scheduled run and a re-scheduled run later this morning and the elapsed times are absolutely crazy. There's a snake in this woodpile somewhere and I can't find it. For no more disk activity than could possibly have happened, there's no excuse for the length of time that re-scheduled run took! I need to go out again soon, but later this evening, I'm gonna run another manual defrag and see if I get a time similar to that 27 minute run. I guess the next thing for me to do is contact Raxco to see if they have any wisdom to add. Meanwhile, I've moved up my scheduled file backup from 2 AM to 1 AM and my defrag run to 2 AM so at least it will be "finished" when I get up in the early morning. One other test I need to make is to (temporarily) disable my nightly AV run to see if that helps. I'll go do that now.

    Re: SP2 And Defrag (XP Pro SP2)

    Al,
    Correct me if I'm wrong but didn't you have a similar problem with excessive time running your backups on an overnight schedule? It turned out to be a problem on your HDs that was fixed by running chkdsk? Again, this is just from my memory. ( which isn't as good as it once was )
    If so, my apologies.

    Re: SP2 And Defrag (XP Pro SP2)

    Nah, sorry, totally different problem. I DID have a problem with TrueImage slowness but it was NOT scheduled and had nothing to do with scandisk (or chkdsk in this case). That was in fact a problem with one of the TI programs. This one just started at the first of the month. Here's a sample of my last three "good" defrags before the problem started:

    Al,
    If you can't identify any processes using an abnormal amount of your CPU during the scheduled defrags I say it is time to contact Raxco. They are reasonably prompt in responding IIRC. One of their support people (Greg Hayes) used to be failry active in the MS newgroups.

    Re: SP2 And Defrag (XP Pro SP2)

    Good timing, Joe. I submitted the question to them late yesterday afternoon, so I'll see what happens and post. For the info of anyone interested, I also DELETED the scheduled overnight scan and created a NEW one, same partitions but at a new time. I don't know if having run a manual scan yesterday helped or if the deletion - addition of the schedule did the trick, but the new run this AM went in about FOUR minutes! Huh? (see attachment if you care to see some history)

    Re: SP2 And Defrag (XP Pro SP2)

    Al,
    That is really strange. You wouldn't think that just recreating the task would make any difference. My normal times are from 3 - 5 minutes with the occasional 15 - 20 minutes. I haven't really bothered to check that out as I just thought it was from my installing/uninstalling/updating/tinkering/etc. I'll be interested to read what Raxco has to say.

    Re: SP2 And Defrag (XP Pro SP2)

    Surely the time taken to defrag is proportional to the amount of defragging required? If you had just run a defrag, I would expect it to run in less than a minute (unless it was still thinking about trying to defrag something undefraggable).

    One thing I find (with Diskeeper) is that it doesn't like running alongside other processes which are writing to disk, nor attempting to defrag two drives at once (physically separate drives is/are OK).
