Excessive hard disk access

Using Firefox (latest version) on OS X 10.6.8.
I was on MapQuest, "get directions," adjusting a route repeatedly, when Firefox began a very long hard disk access. I closed a couple of other programs which at first I thought were the culprit. When I tried to quit Firefox (using Apple-Q) it would not quit. I finally used Force Quit (from right-click on the dock icon) and the HD access stopped.
When I restarted Firefox it automatically went back to MQ and the HD access again resumed. I closed the MapQuest window (which was VERY slow to respond) and again quit FF as above.
When I again opened FF, it opened a blank window (my "Home" is a blank window, "about:blank") and resumed the non-stop HD access. I quit again, moved Firefox.app to the trash, reinstalled from the Mozilla web site, started it again, and the same thing happened.
I have not yet deleted my user data because I don't want to lose my bookmarks and cookies.

The applet is running on the clients machine and if the user accepts the certificate of a signed applet it has full access to the machines file system. For saving files the user needs the rights to write into a certain folder.

  • Slow hard disk access --- still wonky

    Hi,
    Recently i've noticed that hard disk access has become very laggy, to the point
    where it's driving me crazy.
    For example, if i want to tab-complete through my directories, i have to wait a
    few seconds each time.  Similarly with saving files in vim, or just using
    firefox, which seems to suffer frequent hangs while the disk is spinning.
    I tried downgrading the kernel to 3.4.something, to no avail (it definitely used
    to work just fine with the old kernels).  I've also tried adding "commit=60" to
    my fstab to reduce journalling access.
    I ran bonnie++ and the following results came back:

    t
    which (by comparison with other results i've seen online) seem to indicate
    there's nothing particularly wrong with the disk (it's a toshiba 7200rpm, i
    think).
    So i'm at a bit of a loss what to do next.  I've attached my dmesg output.  If
    anyone has any suggestions, that would be awesome.

  • Hard disk access to applet

    hi,
    I have made a signed applet.. my trouble is this applet needs access to the client hard disk as it save the file transfered from the server to a perticular location. I do not want to change the policy file for each client. Can anybody tell me how to solve this problem of accessing the local disk?
    Thanks in advance

  • Any "Hard Disk Access Indicator Monitor" on OS X?

    Activity monitor、iStats menu or so only show the write/read thoughtput of th disks,
    if there's any tool like "FileMon" or "DiskMon" on Windows to monitor which program/process is using the hard disk?

    Tried this (slightly cryptic) command in terminal?
    top
    And theres always console...
    Just remember that disk access is downstream of primary activity once things are sitting in memory.
    if you're thinking you can find out what is busying a hard drive, keep in mind that the driver of a given activity may not be what you think.
    Activity Monitor is still your best window for, well...activity.

  • Hard Disk Access

    I suddenly had problems writing to my hard disk attached to my airport extreme, so I connect it to my computer and got this:
    The Alias "Einstein"(The Hard Disk) can't be opened because the original item can't be found. Do you want to:
    Delete Alias/Fix Alias/OK
    I went to verify the disk, and was told it needed repairing, so I repaired it, and it now says it doesn't need repairing, however I still get the same problem.
    The strangest thing is that I CAN still access it - I went through terminal and it has no problem accessing and opening files, but the finder refuses time and time again, even after relaunching it or remounting the drive.
    I don't have the space to back up the drive fully. It's a 1TB drive, and I have a second 1TB drive, but that one is used as a Time Machine drive, and it backs up a small part of the drive that I have the problem with, but I dont have the space to back up everything...
    Any help would be fantastic

    You could try running the Apple Hardware Test to gain additional confirmation that your drive is good, and you could use Disk Warrior to try to repair it additionally. Also you might consider two other alternatives. First, consider the trade off between losing everything and purchasing a new 1 TB. You might want to purchase a new drive. The other possibility is trashing your TM backup. You can always start over with TM. With either of the last two possibilities, you apparently could use terminal to copy from the questionable drive to another drive.

  • Hard disk access noise

    Hi all, I just bought the DL2100 and additionally two new REDs 3TB each (RAID 1 configuration). NAS is really quiet idle, however every time I access files (read/write/stream) there is a ton of noise caused by the hard disks. Is this normal? I also have an external disk on the USB port. Absolutely quiet even during access. But the REDs spin and work even when I stream off the external HD. Seems to be somthing wrong What is your experience? Thanks in advance!Jimmy

    Hey Mike, I am talking about regular access and seek sound/noise. No weird other sounds.However, I think the hard disks are way too loud! (WD REDs expected to be quiet). I have a lot of old external and internal hard drives - not one is nearly as loud as my new REDs. Maybe I'm spoiled from my SSDs, I don't know. But seriously, the DL2100 should work pretty silent, regardless of file transfers, streaming, etc. Could also be a problem of the whole NAS construction, I don't know. Is there any hardware/software setting for "automatic acoustic management" for the HDs or the NAS system? Thank you!

  • Reading files from local hard disk - Access Local Files Only

    Hi All,
    I have a local flash file published as 'Access Local Files Only', to allow me to read from local filesystem.
    What methods or classes can I use to read text and other files from the user's harddisk.
    This is the first time I am trying to do something like this, all help is grealy appreciated.
    Thanks
    Andy

    Hi, thanks for the responses
    I did some searching and found that the urlloader class is the right one for the job.
    'Access Local Files Only' option is provided for this very purpose I believe.
    If anyone has done something like this and have some sample code it would be awesome
    Cheers

  • MacBook Pro + Time Capsule = Slow Hard Disk Access..

    Hi,
    I know it's an issue with my MBP as my imac is fine with my TC
    Basically connections fail, are sometimes not possible and accessing D/L and Up/L files is so slow I can't even watch a movie from my TC..
    It's only a problem with my MBP though, my other computer is fine..
    I know I could do a re-install of OSX Lion but.. that's a major chore for me..
    I have degraged my comp, used Onyx, I have no viruses and everything is fully updated..
    Any suggestions?

    Clean install is definitely required.. the very idea of upgrade installs have never worked properly AFAIK.. you can patch an OS not upgrade to a new one..
    Thanks for relating your experience.. I have been telling people for a while to do clean install to fix Lion issues with TC.. makes me so pleased to be still on SL.

  • Iomega 2TB EZ Media Constant Hard Disk Access

    Hi,
    I have been provided a replacement 2TB NAS from Lenovo for a previously faulty drive, but this one seems to now constantly be writing something to the disk. Even with all computers on the network turned off, the disk make a short  noise as though its writting to disk and the disk light shows activity. After already having one faulty Iomega drive and loosing loads of data, I am more than a little concerned by this activity as it shouldnt be doing this.
    Thanks,

  • Hard Disk not exist! But spins up ok

    Hey guys, I've got a HP Pavilion DV5 1000ea, which is just over 2 years old. For the last week I've frequently had a lot of trouble booting up, it seems like the hard drive isn't being recognised. I get a message saying that there's no boot device detected, and when I try to do a hard drive self test I get a "Hard Disk Not Exist" error message. At one of these two error message points I also get an error code of (3F0).
    Now, I have tried taking the hard drive out of the laptop, reseating the connections both on the back of the hard drive and on the motherboard, and booting up while the hard drive is laying flat in the palm of my hand. I can feel it spin up fine, it doesn't seem to make any clicking noises like a dying hard drive might, I can even hear it reading the hard drive very briefly once or twice - but I'm still being told the hard drive doesn't exist! On boot up, the "hard disk access" LED on the laptop comes on solid for a few seconds, then goes off, and then maybe flickers on and off briefly once or twice (all while on the HP splash screen) before giving me the error. I should possibly also mention that the label on top of the hard drive looks a bit scorched, I presume that's from the heat generated from the wifi card situated beneath it.
    So the short of it is, this is happening almost every time i try to boot up my laptop now. Sometimes I have to try booting up 10-15 times, but so far it has eventually always recognised the hard drive and booted up and worked perfectly fine with no issues in operation. I just feel that at this stage it's likely that someday the laptop isn't going to boot up at all.
    I'm happy to replace the hard drive if that's going to sort the problem, but since it spins up fine every time with no clicking noises whether the laptop recognises it or not, I wonder if that's really what the problem is. Could it be a faulty cable between the drive and mobo? Could it be a problem on the mobo itself?
    Would greatly appreciate any assistance!
    Thanks in advance!
    johoro

    Think horses not zebras. Not every hard drive error results in clicking. You likely have an issue with the electronic circuitry of the drive, not the mechanical parts, i.e. seek head or platters. A replacement green board would likely fix it but it is much easier to find a new hard drive. Am I 100% sure? No but I am 92% sure.

  • Time Capsule use as hard disk only

    Can I use my Time Capsule as hard disk only?
    Since I have an iPod, iPad, iPhone I intend to save and all my files, including my itunes media in one place and easily access it wireless trough Time Capsule.
    If the answer to my question is yes Can I have a setp by srep explanation...
    I came a few articles and youtube videos but so far not been able to do it

    If you want to have internet, then the TC has to be connected to your modem or router..
    The TC can create its own wireless network. But then you have one wireless network for internet and another one for TC hard disk access.. And you cannot combine them.
    So the best way is to bridge the TC.
    Steps are simple.
    Download 5.6 utility and install it. (you can probably do it from v6 but it has fewer controls and options).
    http://support.apple.com/kb/DL1482
    Go to manual setup, and click the internet tab.
    Go to connection sharing down the bottom.. choose off bridge mode.
    Update the TC.
    Now plug it into the main router by ethernet.. and the TC will be part of the existing network but not interfere with it.
    Wireless should be ok.. but if you need to you can also turn off wireless.
    There are several posts with pictures.. I will try and find one for you.

  • Wont boot past grey screen after disk access was changed

    I have a new 13" macbook pro with OS X Lion. I changed the hard disk access from read only to no access, walked away for a minute, when I came back my computer screen was black.

  • Hard Disk Continuous Activity

    I have a brand new K430 Desktop running WIN7 Home Premium with a 2Tb SATA/600 hard drive.
    The hard disk access light flashes continually at a constant repetition rate of roughly 1 to 2 times/second (and I can hear the hard drive heads thumping faintly at this rate).
     I have no viruses, and Crystal Disk reports the hard drive has no issues.  I ran the Windows Resources utility,  selected the Hard Disk window and monitored the processes & apps doing read/writes to the hard disk. The preloaded McAfee Antivirus Plus occasionally accesses the Hard disk heavily, then goes away. There are other Windows System functions (logging etc) that occasionally access heavily too. All the drive accessing shown in the Resources utility are random with no apparent pattern nor specific repetition rate.
    Not sure if this is a Windows issue or a hard disk hardware "feature", but at this rate the hard disk will likely wear out prematurely.
     I  Google'd this and found that folks having the issue tried various adjustments/options with Windows drive indexing to no avail. So, indexing does not appear to be the problem.
    Any thoughts or suggestions would be much appreciated.
