K8MM-V slow disk

Hello:
I upgraded to a K8MM-V a few months ago from a Asus A7v. Ever since the disk access has been slow. I used the MSI Live Update to upgrade to the newest drivers. I have gone through and optimized Windows XP as many ways as seems possible. I've updated the Bios. The Bios settings are left as standard (auto for most options).
I am wondering if anyone else has had these problems. I am not sure if it is a driver issue or an issue with the Bios settings (since there is almost no documentation provided for setting up the Bios, most things are left at default, except memory config).
I have a Semperon 3100+
A Maxtor 52049H4 as Master on EIDE channel 1 (NTFS) (Windows install partition)
A Maxtor 6Y080L0 as Slave on EIDE channel 1 (FAT32) (Data)
A DVD and CD on EIDE channel 2
Windows XP Pro SP2
1 G ram
Indexing disabled.
Kaspersky Antivirus
Any advice would be welcome.
-Rick

give also some benchmarks results like ATOO and HDtach.
what chipset drivers you have used?
also that "Kaspersky Antivirus" is very laggy solution. drastically slowing down PC performance.
also:
"A Maxtor 52049H4 as Master on EIDE channel 1 (NTFS) (Windows install partition)
A Maxtor 6Y080L0 as Slave on EIDE channel 1 (FAT32) (Data)
A DVD and CD on EIDE channel 2"
your 1st HDD(Maxtor 52049H4 ) is pretty old do not expect great performance from him.
suggest you to move your fastest drive as primary(Maxtor 6Y080L0) and install OS on it.(on dedicated partition)
and move it at IDE1 channel, and connect your DVD as slave.
at IDE2 connect your slower HDD(Maxtor 52049H4) as master and connect your CD drive as slave.

  • TS4027 Slow disk error message in 2.2.1 - even with SSD

    hi, I've been using Mainstage 2 since September 2011 and really enthousiastic on the concept. However, with version 2.1 I had a lot of bugs. The main bug was hanging notes and that is really frustrating when you are performing...
    anyway, i now upgraded to 2.2 which seems to have solved this issue but now i have a different problem. regularly MS comes with a slow disk error which could be caused by underperforming disks or freefall motion sensor. Well, because of that I upgraded to SSD and spend almost 300 euro's to have this fixed. after replacement I had a extremely fast notebook and thought all issues were over but I still get the errors! when the errors ossurs some sounds get removed from the output which is annoying...
    if anyone can help me with this?

    Hi Drew if you haven't resolved this. TRy this to see if the issue is a TRANSIENT object access error instead for submitting directly to Compressor. Do this to isolate any content error defects before making you distribution (older 2 stage workflow)..
    in FCPX 10.1, make sure the projects Primary Storyline is completely rendered - select all and cntl+R (render selection or control+shift+R)In FCPX 10.1 watch the background tasks (+9) and wait for all the rendering to be completed.... (make sure no object errors)
    in FCPX 10.1 export a master File/Share/Master File (+E) as PRORES 4xx and save it ~/Movies/Drews_final_master.mov (prores)
    in Compressor.app V4.1,
    create a new BATCH ,
    import the MASTER object ~/Movies/Drews_final_master.mov)
    (and add your setting and submit it. (dont use FCPX SEND TO COMPRESSOR just yet! until you resolve this issue)
    This process will avoid the use of transient  file storage areas that seem to be used in the FCPX to COMPRESSOR.
    Post your results for others to see

  • Slow Disks After Cluster Creation

    Hi,
    I have a Windows Server 2008R2 SP1 cluster, consisting of two VMWare virtual servers, which is experiencing very slow disk performance (~10mb/s when copying to or from any of the cluster disks). If I destroy the cluster and bring the disks online on a
    standalone server I can get over 200mb/s.  The disks are presented as RDMs, with the two nodes on separate ESX hosts and the disks in Physical Compatibility mode.
    Could anyone explain why disk performance could become so poor as soon as the cluster is created? All the tests in the cluster validation report passed.
    Not sure if this helps, but I have also noticed that when I turn maintenance on for each of the disks in Failover Cluster Manager, their performance improves dramatically.
    Thanks

    Hi,
    I don’t find out the similar issue, you’d better ask VMware® for the more assistance. Base on my experience some third party virtualization often need adjust the disk time
    out value.

  • Slow Disk error when using Finale Cut

    I get a slow disk error when trying to play something in finale cut but when i try to verify disk and repair disk i get Error: Could not unmount disk. What is going on and how do i fix it?

    You have to boot from a DVD or external OS to fix the Disk. You can't unmount a disk that is currently hosting your operating system.

  • Dropped frames caused from slow disks (Disk Speed)

    I just bought a hard drive enclosure that holds double hard drives. http://www.ewiz.com/photogallary.php?name=CA-400MXS2&show=g Inside the enclosure I put two 400G Seagate SATA drives and made them both scratch drives for my FCE 4 projects. Now when I'm inside Final Cut and doing motion tricks for my footage a warning keeps popping up saying "RT EXTREME HAS DETERMINED THESE DROPPED FRAMES WERE CAUSED BY SLOW DISK. PLEASE TRY:
    -INCREASE THE SPEED OF YOUR DISK
    -DECREASE THE NUMBER OF RT LAYERS
    -LIMITING YOUR RT BANDWIDTH IN USER PREFERENCES
    I don't know how to do any of those things above. Now I checked the user preferences and I couldn't find the "RT bandwidth" option to change. How do you change the disk speed or decrease the RT layers??
    Sorry if this is common knowledge. I'm still new with this software.

    Sounds like what I just went through,
    wound up at OWC (as usual) 2 drive 800 FW case was $119
    Mercury Elite Pro
    just remember that if you raid, the drives should be as close to identical as possible.
    i believe this is correct:
    usb 2 = 480 mbps
    fw 400 = 400 mbps
    fw 800 = 800 mbps
    that just means usb 2 & fw 4 are about the same, but fw 8 is faster / better for video.
    Yeah I was looking at that one right after I posted. That's my #1 pick so far. You have an imac?

  • Dropped frames/slow disk warnings

    I'm running a 27in iMac with OSX v10.6.8, 2.8GHz Intel Core i5, 4GB Memory. I have all my media stored on a 4-bay Drobo (auto RAID array, 3-1.5 TB internal SATA drives @ 7200rpm) connected to my iMac via firewire 800. Vidoe files are all quicktime, Apple ProRes422,
    I can't figure out why I'm getting the "One or more frames were dropped due to slow disks" warning.
    Any thoughts on this?
    And I really apologize if this question has already been answered. Thank you so much!

    Good editing drives:  G-Technology, CalDigit, MaxxDigital, OtherWorldComputing Elite series, Glyph. 
    >I know this tends to cause the same error, having you media and your project file on the same disc. Right?
    No...media on your SYSTEM DRIVE is always a no no. Because the system is busy using that drive. I have the project file and media on the same drive a lot.  I back up the file internally, but often use it on the external.
    >I have a 500GB firewire 400 drive I could transfer it to as plan C, but I currently have it daisy-chained to my mac via the Drobo,
    Disconnect it.  Don't daisy-chain anything to the Drobo.  Have only the drobo connected via firewire and see what happens.

  • Dropped frames during playback due to "slow disk"

    I work off an external Rocstor 160gb firewire drive; suddenly as I started to edit a project I get constant dropped frames during playback. It says it's due to "slow disks" and I wondered if my hard drive was dying. But I opened other projects on the drive and they play just fine. Why just this one? It's shot on the same format, captured the same -- nothing's different from my older projects. Maybe the captured media files got corrupted? I've never seen this. I've tried using the Rocstor on three different machines (first a 17" PB, then two different G5 towers) and it happens on all of them. I have FC5 on the PB, but FC6 on the G5s -- doesn't matter. I'm stumped here.

    How full's the drive? The fuller it gets, the slower it becomes. If it wasn't a superfast FW drive to begin with (especially a 400 device) You're gonna have problems as it gets fuller... starts slowing down big time around 70% capacity. It's always something... if the drive's not in a fast enclosure, and is also a fastish drive has a least 8mb disk cache, it will behave like this with DV footage.
    One thing I've seen and learned from reading a few posts on this is that the better/faster stuff suited for FCP use is worth the investment. G-Raid, Grainite Digital, OWC all sell really nice FW800 setups... they are up to twice as fast as older/slower FW 400 drives. and NEVER buy any more than you need now for storage. It's half the price and twice the speed next time you need more it seems.
    eSATA should be considered by any pro. laptop or not.

  • Slow Disk Access

    Hi,
    I have a Dual 2.5 Ghz PowerPC G5, which has two 250GB hard disks. I also have a Lacie 250GB Firewire hard disk installed. I am using Mac OS X 10.4.4.
    When use this computer the CPU and disk performance are OK. However, whenever and application uses a File Open dialog to find or save files the dialog (such as with Macrosoft Word, Macromedia Flash etc) is incredibly slow. It can take up to a minute before the application will find all the files and display them. This is incredibly frustrating. I mean, I hardly have any files! Is there anyway to fix or resolve this problem?
    Thanks, David.

    1. Did you try the advice in my FAQ w.r.t. Energy Saver settings? The spin-up noise may be too low for you to hear: some drives are nearly dead silent in this respect.
    2. There are only two other things I can suggest:
    - Open Activity Monitor (in Applications > Utilities). Sort processes in descending order by %CPU and monitor it when the problem occurs.
    - Check Console for clues after the problem occurs.
    Good luck!

  • How to measure slow disk i/o impact on video graphics performance???

    The problem is when an application runs in fullscreen with a high FPS and still shows lag/stutter issues in graphics ...
    Windows 7 doesn`t seem to have any tools that report of stuck disk i/o traffic and neither does the graphic card controls (nvidia). The missing information seem to be:
    1) Whether it is because of a slow drive (fx. http://www.youtube.com/watch?v=QF-SBypQBuw); (Solution: buy a faster drive)
    2) Whether it is because of other programs using the same disk - fx. windows pagefile(?); (Solution: move the app to another drive)
    3) Or whether it is because of a layer program - fx like Sandboxie that redirects filesearch etc.; (Solution: run the app outside the layer)
    Is it really necessary to buy and install and configure a new harddrive and then install the app on this drive uncertain of results just to compare to try solving some graphics lag because of disk i/o issues?

    1) the Windows performance index gives a view of the hardware's expected performance the subscores for harddrive tests should allow you to determine if your harddisk is 'slow'
    2) Resource monitor can help to identify processes that have a lot of IO. Most important measurement will be teh disk queue length. To get even more detailed information, you could use perfmon.
    http://blogs.technet.com/b/askcore/archive/2012/02/07/measuring-disk-latency-with-windows-performance-monitor-perfmon.aspx
    3) virtualisation and/or sandboxing always has a performance impact. You should check with the software vendor how to check for/test the performance impact the application has.
    no, it is not neccasary to buy hardware or software to identify a performance issue. note that in some cases is might be easier/cheaper to buy some new hardware of which you are sure it will meet all requirements.
    PS: consider purchasing an SSD if yous suspect IO issues and are willing to spend some: it will be your best hardwareupgarde you did over the last 10 years!!!

  • Macbook pro mid-2012 13" has very slow disk access

    Until 3 days ago my macbook pro mid-2012 13" running OX 10.8.3 was running fine. Then, it showed very slow response anytime it had to access the hard disk. After doing the usual checks and disk first aid repairs to no avail, I booted from my external disk with an older copy of my hard disk and everything then worked as normal, except when I accessed the internal hard disk, then it crawled once again (spinning beach ball, took many seconds just to open a finder window and then several minutes to display the contents). I ran the Apple Hardware Tests and it said everything was fine, even though it tooks several minutes before the test would actually start. I also ran the program BlackMagic Speed Disk to find out if the disk was having transfer speed problems and it showed a respectible transfer rate (60MB/s), not great but not like the 0.3MB/s I was getting when I tried to back up the internal disk. I was using Carbon Copy Cloner to try to back up the internal disk but had to give up since at 0.3MB/s, it would take days to back up the 250GB on the disk. I found on the web that using "restore" in Disk Utility, I could do a disk copy without the file by file copy which allowed me to back up my disk in "only" 6 hours. Booting from my newly made copy on an external disk worked fine and ran at nearly normal speed (slightly slower since it was an external disk running through USB2). As a final attempt to prove this was a disk problem, I erased the internal disk and reinstalled OSX 10.8. I am still waiting for this install to finish, it has been 5 hours although the progress bar said it should be done in 20 minutes. This was fairly convincing evidence that it is not a software or settings problem. However, all my web searches could find no other case of a problem like mine. I presume I have a failed hard disk but as all the diagnostic programs say it is working fine, I was hesitating to bring it in without hard diagnostic evidence. If anyone knows what might be the problem, it would be much appreciated to hear from you.       

    It should not take 5 hours to install Mac OS X.  There is something wrong with the disk.  Try reformatting where you do a wipe of the drive (an select the option to write zeros which will remap bad sectors).   Then try to install MAc OS X.
    I got this information from here:
    http://reviews.cnet.com/8301-13727_7-20064489-263.html
    Back up your data.
    Use Time Machine or a system cloning utility to create a full and restorable backup of your data. If you suspect bad blocks, then when cloning you might consider not using a "block-level" copy process, since this will likely run into problems.
    Boot to the utilities DVD.
    If you have a boot DVD for a tool like Drive Genius or another drive utility, then boot to that; if not, use your OS X installation DVD (once you select your language, open Disk Utility from the Utilities menu).
    Format the drive.
    Using your selected utility, format the drive and check for bad blocks. If you are using Disk Utility, click the Erase tab, click the Options button, and then select the option to write zeros to the disk (you do not need to do multipass erase options, as this will provide no additional benefit for managing bad blocks). Writing to zeros may take a couple of hours depending on the size of the drive, but when done the drive will have remapped any blocks that were not reliably read.
    Restore the OS installation.
    If you have used Time Machine to create your backup, boot to your OS X installation DVD (if you are not using Disk Utility) and use the option in the Utilities menu to restore from backup. Attach your Time Machine drive and then proceed with the restoration, selecting the newest backup as the one to restore to your system. If you have used a system cloning tool, then attach the cloned drive and boot off of it (hold the Option key at start-up to select it from the boot menu). When you are booted to the cloned drive, run your cloning utility to copy the installation back to the computer's main boot drive.An optional approach here is to perform a full reinstallation of the OS from your installation DVD, and then migrate your data, applications, and settings from either the clone or the Time Machine backups using Apple's Migration Assistant.

  • Very slow disk performance in Bootcamp 2.1 with XP Pro SP3

    Tried bootcamp today and for some reason disk access is painfully slow. XP shouldn't have these issues on such a fast machine. Is this a known issue? Is there a work around?
    As it stands XP cannot be used for anything useful due to poor disk performance.
    Any help greatly appreciated.
    RobP

    After more digging around I discovered that Bootcamp was operating my hardrive in PIO mode rather than Ultra-DMA - hence the very slow performance. I tried looking for drivers but failed. In the end I installed Vista Premium 32bit and everything now seems fine.
    I wonder if bootcamp will get updated to give XP users the full speed of their Mac Pro drives?
    Either way, I'm now sorted

  • Qosmio X505-Q870 with "slow" disk access

    i"ve got a several month old X505 870 with 4GB of memory and TWO Hitachi 7200 rpm 500GB SATA II hard drives. The system is used primarily for initial examination of digital images, with each image being around 20MB. Accessing images to display previews is perceptibly slow. YES, the system is tuned to the best of my ability. YES, both disks have been, and are REGULARLY defragmented - both show 0% fragmentation. YES, I've thrown away the original O/S with all the trialware, stupidity, and goop, and installed W7, 64-bit. YES, all the drivers I'm aware of are current, including the Intel storage drivers. NO, other than the periodic Side-By-Side errors that show up every couple days, I'm NOT getting application or system errors.
    In Bridge or Lightroom I"m not getting CPU bound, but this thing beats on the disk(s) quite a bit, and takes MUCH longer than the desktop system to display images. YES, the desktop is a slightly faster CPU, but it
    also has standard 7200 rpm drives for images, and it's SIGNIFICANTLY faster at retrieving and displaying images in Bridge or Lightroom...
    Is there any PRACTICAL (no, putting in 2, 500GB SSD drives is NOT practical) thing that can be done to improve disk performance on this box, 'cause right now it certainly isn't any speedster?

    I don't have any empirical evidence about whether the original installation was this slow, but my recollection is the reason I dumped an re-installed a clean W7 was because the original was REALLY a dog. I also wanted to put partitions on the drives and the original installation caused problems with the partitioning... But, I'm confident that the original was definitely not faster...
    As far as drivers, I believe I have everything current.
    My antivirus is Microsoft Security Essentials, but I currently have it turned off. So that's probably not the issue.....
    As far as "is it really slow", I can't say. It's SLOWER, but I suppose if you're not doing anything very demanding it'd probably be all right. It's just significantly slower doing what I do, than my desktop. I don't have anything else to compare it to, but it SEEMS (the ever popular "seems") to me that a quad-core with 4GB of memory and 7200 rpm drives should be extremely quick to pull up images and render previews. But, I'll admit my expectations may be too high.
    Which is why I'm hoping there's something I've neglected that'll make things perform better. I even dumbed down the interface with the "best performance versus best appearance" thing to see if that'd help. Didn't.

  • Really slow disk access

    our iMac runs like a dog. I've max'd RAM, cleaned and optimized the hard drive. Configured with two non-admin users (myself &amp; my wife - I need right-click but it drives here crazy), and an admin account. iTunes and iPhoto libraries are shared, and they are stored on an external 500g drive. in addition we have TimeMachine active to a 2tb drive thru. External drives are connected thru the USB hi-Speed bus.
    Examples of slow: up to a minute to switch users, 10-20 seconds for a cursor in Spotlight, Safari takes about a minute to get "warmed up".
    I decided to do a clean install of Mavericks - all previous updates/upgrades were automated via Apple and/or AppStore.
    So I'm creating a redundant backup of folders on the internal drive (everything except movies, music, &amp; photos which are on the 500g and backed up via TimeMachine on the 2tb drive).  in total only 172g to copy to another 1tb drive.
    I started last night, but it went to sleep and did not work all night. in total it's been working 4-6hrs last night and 8hrs today. There is still 22hrs to go!
    Is there any hope for this machine?
    Larry :-)
    ========

    I watch Activity Monitor a lot, CPU never really seems to be stressed, nor the Disk. While I don't know how to read the Memory monitor, "memory presure" is typically stable at about 25%.
    The terminal showed 0.0 pages written to the pagefile - taken while only doing back-up and Activity Monitor, no real change now that I'm also in Safari.

  • Extremely slow disk in Macbook Pro 3.06 dual core (8gb, 500GB / 7200rpm)

    For some weeks my Macbook has seemed slow.
    To see if I could fix this I started doing all the tricks with repair permissions, iDefrag. I've also checked the system.log (with console) and I've removed any problems in the log. None of the efforts has changed anything. It's still slow.
    Finally today I found xbench (and geekbench - but stay away from the last one) and ran a test on the system. The result is scary .. Overal score is 63.74 where an old Powermac is index 100. My Disk Test peaks at 11.82 where the Powermac is 100.

    What does Disk Utility say about the SMART status of your hard drive? You may also want to download and run [SMART Utility|http://www.volitans-software.com/smart_utility.php] and see how it evaluates your drive.
    The 250GB, 5400RPM drive in my MBP 5,1 (the 15" unibody model immediately preceding your 17") scores about 40 on the overall disk test in XBench, so there is clearly something wrong with your drive, which should be faster than mine.
    How much free space is available on the drive?

  • Oracle 10G Slow Disk Writes

    We have currently purchased a "SUN SPARC Enterprise T5220" with 2 x 146GB 10K RPM SAS and 2 x 72.8GB 10K RPM SAS disks. I have installed Oracle 10g and created a datbase. The TEMP tablespace and REDO logs and data files all reside on dedicated disks. I have mounted the TEMP, REDO and Datafile filesystems as forcedirectio and set the Oracle setting FILESYSTEMIO_OPTIONS to "SETALL". The speed when writing to disk seems very slow, most of the top waits on the database are for "log file parallel write", "db file parallel write", "direct path write temp",
    cann anyone advise on what I might have done wrong.

    Why do directIO on a local disk. DirectIO should be used when you are using a disk array that has cache on it to avoid the double cache hits (IE system cache hit one and then the cache hit on the array).
