Why my drive hard Boot keep reading and writing for 20 minutes after the start?

As the title says my HDD Boot continues to read and write for about 20 minutes after the start. Read and write up to 10 GB in the process. I would say a good way to destroy a disc. I have not seen this behavior in any other OS.

10.10.5 OS version

Model: Mac Pro

ID: MacPro3, 1

Processor: Intel Quad-Core Xeon

Number of processors: 2

Total number of cores: 8

(Vivid RAM) memory: 8 GB

Any help will be greatly appreciated.

Thank you.

Check Console.app and see what happens.   Could be something of a time Machine for Spotlight indexing to a process of runaway of an OS X or a bug in the application.

    When starting 11 AR (whether via its icon or a .pdf document), AR starts normally, but after a few seconds the interface freezes and unresponsive for about 30 seconds. Connection at startup with Process Monitor gives the result below (actually two instances, only is indicated). When the second instance times out (I guess this is what happens), AR11 starts responding again.

    The problem disappears if the Weblink.api plugin is deleted, with the side unhappy effect as the tool on the right pane also disapperas (replaced by a spinning icon but AR11 otherwise responsive).

    AR11 installed on the server doesn't have any Internet access either. My guess is that AR11 is looking for the host above for some reason any and need some time before it becomes available for use. This is obviously a very poor design and we want to solve somehow... Ideas anyone?

  • My reading and writing system does not recognize the DVD. For this CD. I don't know why.

    For a long time my system CD/DVD in my laptop Del Estudio 1537 worked perfect. But all of a sudden my computer does not recognize or read or burn DVDs. Can you help me fix this problem?

    Hello

    You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
    Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
    correctly.

    Burning at low speed, or by using the master could help. A CD/DVD cleaner might help.

    Brand of the CD or DVD drive can also be the problem. Low quality (cheap brands) are always problematic.

    CD/DVDs have a tolerance + - and your can read/write on the edge outside these discs
    tolerances. They may be delivered, but it is generally more economical to replace the disk.

    PeterM

    I found the answer to this one, if anyone is interested, even if the solution required a work-around on the way. Suggested HP support I have just uninstall and install software downloaded from their site (PS_AIO_04_C4500_USW_Full_Win_enu_120_210.exe). This indeed solve, and another problem I had (see network & Wireless forum), but this download is missing the software package I.R.I.S. OCR, presumably for reasons associated with 3 rd-party lisensing. HP support insisted that this download was the OCR, but the OCR .exe is certainly missing. Workaround needed to go back and re - install the CD software, then uninstall everything except the OCR package (you can do), then install the downloaded version. My PC still takes too long to start, but it's probably the combined effect of each software package, I never installed wanting home phone so that it loads.

  • simultaneous reading and writing on a PDM file

    I found similar discussions on here, but none that satisfied my problem. I'm running several loops within a vi, which writes data in a permanently .tdms file. Another loop to finish its task from the start in a test, and I want to transition this loop so that it accesses the file writing and started writing on a network. It also enables me to check that the data is being stored in the file and that it is corrupt.

    I started with just the basics, but when I pass the second loop to read the file that is is always written off mistakes, saying that she met at the end of the file. It does if I put the count 1, -1 or anything in between. It illuminates, however, the end of the file output.

    I have the entry in the file tdms on PDM read wired to a local variable, just as I do writing PDM, they all have both read the same thing and I get an iterations of a data value of the reading, so, apparently, file access is no problem. And I have to someone who cringed to local variables, ensure that reading and writing are not activated until the local variable is updated.

    Try to set the "group name" entry on «TDMS read» If you write more than one group, you can use "View the contents of the DDHN" in order to get a list of groups.

  • Why lsass.exe consumes resources after the start?

    Lsass.exe turns 15-20% cpu level for 10-15 minutes after the start.  I have a fast, dual-core machine and the latest XP.

    Hello

    "lsass.exe" is the local security authentication server. It checks the validity of the user on your PC or Server logons. Lsass generates the process responsible for authenticating users for the Winlogon service. This is done by using packages of authentication such as the default, Msgina.dll. If authentication successful, Lsass generates the user access token, which is used to launch the initial shell. Other processes that the user initiates then inherit this token. More information

    Note: The lsass.exe file is located in the C:\Windows\System32 folder. In other cases, lsass.exe is a virus, spyware, Trojan or worm!

    If you suspect a viral activity, and then run Microsoft Security Scanner and check.

  • is it possible to see EVERY folder and file that exists on the drive hard on one screen and in one place just as you could do in much older versions.

    OK... so I had an accident and there was good and bad news... the good news is that I was able to get it started and running "Save", but the bad news is that instead of giving a new image system clean (as I expected), I had a bunch of random pictures and other unimportant things and many important things seems lost but I think that its still all somewhere.

    now... to the front sometimes there was a windows program called "windows explorer" that would put all folders and all files that was on the hard drive on a single screen, and you can search through them.    When I shoot to the top of the Explorer windows on win 7, I get a page with a bunch of files minor that some things in them, but not what I see already...

    so... my question is simply "is it possible to see EACH file and a file that exists on the drive hard on one screen and in one place just as you do in earlier versions.    I did some research and went thru records that he will show me but I explicitly want is to see EACH file and folder that exists on one screen...

    Steve,

    Are you talking about the Windows Search function?

    In Windows Explorer, open the top-level folder that you want to watch in [C:\Users\yourusername\Documents or whatever it is you want] then look in the upper right area - there is a white box to the right of the address bar.  This is the search box.  Type * and then pause and it lists all the files in this top-level folder down through its subfolders.

    Best regards

    Hello

    Step 1: Please do all the same underneath if you did some before as it is often the set of operations which solves the problem.

    Try this double click Control Panel - Device Manager - CD/DVD - device - tab - click on update drivers (this will probably do nothing) - then RIGHT click the drive of the driver - UNINSTALL - REBOOT this will refresh the default driver stack. Even if the reader does not appear to continue below.

    Then work your way through these - don't forget the drive might be bad, might have a cable loose or slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables at both ends. Remove and replace, do not just tight. For laptops, you can often clean power and contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the system manufacturer and the manufacturer of the device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (burn CD & DVD and CD and DVD read). Therefore, it is not unusual for 1 or 2 rooms with not so work that others do it properly.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are some entries in the registry that the troubleshooter does not solve, and those who "could" be the cause.

    Check with your system manufacturer Maker and device for possible firmware updates and the correct registry entries for your car.

    These are the keys in my opinion, are those in question - secondary-keys for the CD/DVD drive of course because there will be other subkeys in these keys. Be sure to ask specific keys involved as well as the parameters.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

    You can probably find more information here and maybe even registry settings correct for your CD/DVD from someone with the same drive model.

    I hope this helps.

    If you encounter this flicker, then the next troubleshooting step is to restore from a backup. If the behavior persists after the restore, then the last step is the factory restore. If after the factory restore and adding no additional content, you see always this problem, then you must make an appointment at the Genius Bar to the nearest Apple store or service provider authorized Apple to have the material examined. If the behavior goes after the factory restore, then sync again your content manually, without using the backup. It seems to me it's corrupted content in the backup.
