External hard drive driver suddenly 'not installed'

  1. This is driving me crazy. My Maxtor ext drive (USB) is not listed in My Computer or Disk Management but IS listed in Device manager. It was working fine until after I cloned my old c drive onto a bigger internal drive. I can't see how this could affect it though.
    Disk Manager says 'No Driver Installed for this device' , but when I click on Properties/Driver details there are a number of entries with green ticks.
    I tried to uninstall the device but this just freezes Computer Management. The PC will then not shut down completely.

    The drive works fine on all other PCs.

    Any ideas?

    Based on your symptoms and data in your screen shot, I'm guessing you had Acronis True Image installed at one point and then removed it?

    The snapman.sys driver file shown in your screen shot is part of Acronis TI.

    Let me know if my guess is correct.. then I can explain what happened and how to fix it.

    My bad. :confused:

    My brain just snapped by into gear.... The problem may not be exactly what I thought it was... but Acronis may still be part of the problem

    Is it still installed?

    It could well have had Acronis installed, I don't recall doing it though. I did install a free cloning/image app (forget the name ) to clone c drive. I then installed Partion Magic to combine partions on the larger newly clone drive but this did not work so uninstalled it. I then wiped the new drive then installed a Seagate app to re-clone the old c drive with correct partitions. Is this relevant? Since posting I have discovered pc will randomly not recognise other ext hard drives as well. USB sticks are ok.

    I am also getting 'Procedure Entry Point Not Found in Msvcrt.dll File' on start up.

    Thanks for trying to help.

    1. As best as you can recall, Did the Msvcrt.dll error start about the same time as the Disk problem? Or start a different points in time

    2. Look in Add/Remove Programs (or Programs and Features). Do you find Acronis True Image? or ANY other Acronis True Image product still installed?

    3. Download Filter Driver Load Order to your Desktop. Run it. Select your USB drive, the click Clipboard. Then paste the info to your next post

    Ok, Nothing called Acronis on this system. Never has been. I do have Acronis on another PC but not used. There is an Acronis entry on the attached Seagate usb drive text file. I don't know why. Maybe I tried using Acronis on the other system that this drive is usually connected to.This drive works fine on both systems, though it sometimes fails to load when I try to connect then remove the Maxtor drive on this dogy xp. This process causes the PC to hang. It then won't switch off properly.

    I have attached the Maxtor USB text file as well.

    The Procedure Entry Point Not Found in Msvcrt.dll File error started before any cloning action. It came out of nowhere... or maybe just after I downloaded cloning software. Hard to remember. I have downloaded and replaced the old 'wint32u.dll' but no effect. The new one was twice the size of the old one. Seems odd.

    Did you forget to attach the text data from the Filter Driver Load Order Report (post #5)

    Fyi editorial note: No need to quote prior posts unless there's something specifically in there you want to highlight in your next post.

    That said. Bingo!@ Yea, I think I see the problem. But hang tight till I have a chance to write more either tonight or more likely sometime later tomorrow.

    snapman.sys and visflt53.sys are both Acronis disk driver files.

    This is what I think is happening
    > Both snapman and vidsflt53 are both defined in the registry as disk driver files
    > The file snapman.sys is till stored on disk but visflt53.sys has been removed

    So Windows is trying to find a driver file that no longer exits. (I;ve seen Acronis and well as some other apps that uninstall but still leave remants behind that cause problems.)

    Double check
    1) Look in CtlPnl->Program and Features again double check if Acronis is listed or not?
    2) Then look to see if c:\windows\system32\drivers\snapman.sys and c:\windows\system32\drivers\vidsflt53.sys are stored on disk. (I believe snapman exists, vidsflt53 does not)

    Let me know result of above and then I'll tell you how to fix the file references in your registry that are causing problems

    Ok, Acronis not listed in Add/ remove programs list. (XP)
    snapman.sys is there, vidsflt53.sys is not.
    Over to you! :)

    This fix requires modifying the registry. So, create a System Restore point before proceeding (just to be safe)

    NOTE to anyone else reading:! The following instructions are specific to MD3000. Someone else may require different changes to their Upper and Lower Filters.
    • Open an administrative command prompt. Type regedit
    • Carefully navigate to registry key
    • Verify you arrived at the right key. If at the right key, you should see a subkey / value pair towards top of the list that reads
      Class    REG_SZ    DiskDrive
    • Right click LowerFilters select Delete
    • Right click UpperFilters select Modify.... Edit value data such that only PartMgr is there. When done they subkey/value should read
      UpperFilters   REG_MULTI_SZ   PartMgr
    • Click File->Exit to close regedit. Reboot. Now check your USB drive again

    You did it! Drive is now running on this system. I still have the Procedure Entry Point Not Found in Msvcrt.dll File error on start up but this does not seems to cause any issues, apart from being irritating.
    Can't thank you enough for your help. :D

    Yippeee! High Fives! We did it,
    I probably won't have time to followup with msvcrt.dll till the weekend... but we'll try tackle that one too!

    Hi @MD3000

    Let's see what we can do about that annoying msvcrt.dll message

    Does any other information appear in the error message window? Anything useful in the title bar across the top of the window?

    Then see How to Create and Event Viewer report. We'll check to see if Windows left any clues there

    Hey, very sorry I did not spot your post! Strangely no email alert this time.
    There is no other information apart from what I have already posted. I have uploaded the event report. I am guessing it will make more sense to you than to me! There is another unrelated error in the list about printing failures. This has been on the system for ages, I fix it by turning printer off and on.

    I don't know if it's related to your error or not but there's one interesting System error that keeps re-occurring (you might check the date/times against how often you see your error message)
    Event: 7026 Source: Service Control Manager
    The following boot-start or system-start driver(s) failed to load:  avgtp 
    Do you have AVG installed? Is it the paid or free version?

    > Download AVG Remover then disconnect from internet
    > Uninstall AVG. Reboot. Does the problem still occur?

    > You can reinstall AVG see if problem returns

    Ok, removed AVG (free) and reboot but error still there. Now reinstalled AVG.

    I don't think that event would cause the error you see on startup. That event occurs at log off. It has to do with a program or service having a registry key open when windows wants to log you off and close the registry.

    Are you still running XP? You can install User Profile Cleanup Service from M$

    As to the error message you see on startup,
    1) Try booting into Safe Mode. Does the message go away?
    2) If yes, the start XP in a clean boot. Is message still gone?

    If yes, then you can follow the instructions in clean boot debugging to try and determine which program startup is causing the message to occur

    Whoops. Brain reboot. There is more info on the warning banner. Teamviewer.exe causes this when it loads on start up so will do an un/reinstall before trying your steps

    Uninstall of Teamviewer got rid of alert. Did a reinstall, error back. It does not seem to affect the operation of this app. I installed User profile Cleanup as well, but error still there on reboot. Here is the full text:
    TeamViewer.exe - Entry Point not Found
    The procedure entry point_except_handler4_ common could not be located in the dynamic link library mscvrt.dll

    I'm wondering what version you're running of the dll. Let's check a few things
    1) You're running XP Service Pack3, 32 bit, yes?
    2) All critical Microsoft updates are installed?
    3) For Teamviewer, click Help->About. I have v9.0.24951

    Next we'll check the version of msvcrt.dll in system32 and dllcache. To find the dllcache folder see HERE to first show hidden files and Folders. Locate files

    For each file, right click Properties->Version.

    I see v7.0.2600.5512, Copyright Microsoft for both files
