Restrictions on access to a USB flash drive

good day... I have problem with all the USB flash drive... before, I can see flash drives in my computer and browse its content but now Windows does not show it in workstation.  Windows can still recognize flash drives but it will show under devices instead of workstation.  However, when I tried to browse the content of the flash player, I received this message: "this operation has been cancelled due to restrictions in effect on this computer.  Please contact your system administrator. "Because of this restriction, I can no longer navigate and access my files in my flash drive.  I check my user account and see that I am, log in as an administrator.

I tried the solution to uninstall and reinstall the USB controllers and editing the registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\USBSTOR 'start = 3'), but nothing helped.  The problem is still there.  I can still access the files in my flash disk.  Moreover, my flash drives work perfectly well on other computers.
Please help... Thank you very much.

Hi thafaceface,

Welcome to the forum.

Before reinstalling Windows, I suggest you to check the system files are they work very well or not and to check who are trying to run the (SFC) System File Checker tool.

Scan SFC will be scans all protected system files and replaces incorrect versions with appropriate Microsoft versions.

How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

  • Go to Start, click all programs and open the Accessories.
  • Right-click on command prompt in the list programs, and then select run as administrator. If you are prompted for an administrator password or for confirmation, type your password, or click OK.
  • In the command prompt, type the following command and press ENTER:
  • sfc/scannow

For more information, refer to this link:

Get back to us with the result of the analysis, and we will be happy to help you.

Kind regards

  • Satellite L675 - 11 H - cannot access and/or played on USB flash drive files

    Hi all

    I recently bought a Toshiba Satellite L675 - 11H and tried to transfer files from a USB Pendrive on my hard drive from Toshiba. The files were already transferred from my old laptop (HP - XP) on my USB flash drive.

    Unable to access the USB flash drive to any of the USB ports that I connect my new laptop flash drive. What could be the problem here? Thank you for your help or tips!

    Hey Rush,

    Can you post more detailes about this behavior? What happens if you connect your laptop HARD drive, you don't see that Windows installs the drivers for the new USB device or do you have an error message? If you have connected the USB check of Windows disk management if she s recognized there (Control Panel > system and security > administrative tools).

    Have you tried other USB devices such as USB mice? If they don t work too the problem might be connected to the USB ports. In this case, you must delete all the USB ports on the Device Manager and restart your laptop. Also the chipset driver update might help.

  • Satellite L20-100 cannot access a USB Flash drive

    I recently bought Toshiba Satellite L20-100
    I installed a USB in Kingston datatraveler flash drive and windows recognized it without problem.
    but when I open my computer there is no icon for the reader (it works on another computer well).
    the drive is recognized in Device Manager, but it is not given a drive letter.
    When I open disk management and try to give it a drive letter it still does not show on my computer even after a reboot.

    Although I can access the disk management flash drive and can open, copy & paste the files & to her.
    same problem happened with a card reader.
    other USB devices like cable modem & mouse work well

    What is the solution

    Hello

    Is it possible that the USB is not formatted? Try changing the file system on the USB key.
    You can also try to change the drive letter because the letter assigned automatically sometimes gives some conflicts with other readers.

    Second possibility:
    You can try to clean all the USB stored device settings and let Windows refresh their.

    Create a file with Notepad containing the following lines and save it as a BOOKMARK. REG
    -cut after this line-
    REGEDIT4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Environment]

    "DEVMGR_SHOW_NONPRESENT_DEVICES" = "1".
    -cut before this line-

    Double click on FIX. REG and say yes to the merge into registry question.

    Unplug ALL USB device.
    Open the Device Manager.
    View, show hidden devices.
    Uninstall all devices under USB controllers.
    Uninstall all devices in hard drives that you know are not present.
    Uninstall all devices in storage Volumes. Say no to all reboot prompts until you are finished.
    In addition, if a storage Volume doesn't uninstall, ignore her and move on to the next.
    If you have a yellow? with unknown devices, uninstall all of the entries there as well.

  • Windows Explorer stops working whenever I have connect a USB flash drive and try to access

    Hello. I use Windows Vista.

    I had a particular problem. Whenever I have plug in a USB key and try and access it, I get a pop saying "Windows Explorer has stopped working." the file is closed. If I wait a long time (i.e. 10 seconds), I might be able to get into the drive without any problems, but even when there is no guarantee. The problem persists in each USB slot I use. In addition, it is not that the computer is not able to detect it. It can detect and identify that it is a USB flash drive. It's just that whenever I try to access (or the folders inside the flash player), windows Explorer stops working and restarts.

    Does anyone have this problem before? And any help is appreciated. Thank you.

    The mistake made reference the MSVCR80.dll, which is a Microsoft file, but it may be another third party file, causing the problem.

  • ScanDisk USB Flash Drive problem after upgrade to El Capitan

    After the upgrade to El Capitan, I can't access the vault secure on my USB Cruzer facet flash drive. I have Plug and display files as usual but when I try to open the safe, I get the message ' Scan Disk Secure Access V 2.0 requires San Disk USB Flash Drive. Please insert one. »

    The Flash Player has worked fine before the upgrade to El Capitan and I can still use the files outside of the secure vault but, basically, I cannot now access the secure vault. I'd appreciate any thoughts on how this can be resolved. I only am not an expert so please, keep it pretty simple.

    Sounds like a problem of compatibility with the Secure Access software and the OS X El Capitan of SanDisk.  Try download and install the latest version of Secure Access of SanDisk.

    It seems also be other users having the same problem, you may get better assistance with this through SanDisk.  Someone else said that upgrading to the latest version of Secure Access has solved the problem.

    Hello:

    Looking at your other posts it seems that you have yourself painted in a corner.

    Since there is no inheritance or the setting USB auto in the BIOS, your only option would be to remove the hard drive, then put it in a USB drive enclosure sata hard laptop, plug in another PC so it can be read, download the drivers there, you need and copy to you user profile on the hard drive removed.

    Chapter 5 maintenance manual provides the procedures of withdrawal and replacement for the hard drive.

    http://h10032.www1.HP.com/CTG/manual/c03733656

    Reinstall the hard drive, run the drivers, and you should be good to go.

    These would be the drivers you need for your model...

  • USB flash drives do not work

    Hi all

    I have a couple of USB flash drives. I recently got a new computer and none of them work. They work on a computer with Vista and a Macintosh running leopard OSX. I tried to install the drivers for them, but they do not work. I tried to uninstall the from Device Manager, but they don't always work. Also, one of them appears SOMETIMES (very rarely) and when he does works incredibly slow and unresponsive so. I searched the internet for each method I can find, but nothing yet. And they work very well on other computers. Can I use bluetooth USB and a USB mouse and pregnant too much work, but the sticks of memory will not work. Also do they not appear on Device Manager. I have Service pack 3 2002 edition came with the computer.

    Hello Hasan516,

    Thank you for your message.  Have you tried formatting of thumb drives?  If you have data on them, you will need to copy these data to a computer first.
    If you can see the drive but not access it under XP:
    Open 'My computer' > click the drive and select "format...". »
    When the Format window opens, scroll down the "NTFS" file system, and select 'start '.
    Please let us know if this is or is not to solve your problem.
    See you soon

  • You are looking for a SIMPLE, EASY to USE, USB flash drive password protection

    Hello everyone,

    I scoured the Internet looking for a SIMPLE, EASY to USE, method of Word to PASS-PROTECT my flash drives TOGETHER.  I don't mean something that protects just individual files & folders (such as MS Word, Excel & can do).  Or I'm looking for a program that involves having to read page after page of instructions on how to ENCRYPT the drive.  ENCRYPTION is a topic that is really beyond my ability to understand.  I'm sorry.

    Programs like Truecrypt, Axcrypt, etc. are simply much too complicated for me to understand... a lot less!

    My question: are there flash drives available (size 8-16 GB preferably) who have a means of securing the disk with a password?

    The USB key remains in my USB port at ALL times!  I have no other computers here and live alone, so that no one else could access the flash player (or computer).  Otherwise, I would be willing to consider a VERY SIMPLE, EASY to UNDERSTAND AND USE application, either free or something that does not cost me dearly.  (I subsist on a limited monthly disability income).

    Thank you for your time and any recommendations!

    It seems that the solution for you would be to purchase a secure Flash drive.   Security is built-in and it asks for your password when you insert your disc into the computer.   Can't get much simpler than that.  They are a little more expensive, but you pay more for practical reasons.   See the following article:
    'USB Flash Drive Security '.
       <>http://en.Wikipedia.org/wiki/USB_flash_drive_security >
    To find one, just Google for "Secure USB flash drive", there are a lot of them out there.

    If you have a non-secure flash drive and do not want to replace, then your easiest option would be a program like Truecrypt which you already have reduced as being too complicated.  Don't let the word"encryption" you scared - it all comes down to "enter a password to access".»  Once established, however, it is almost as simple as only to enter a password so if you can find a computer or a local high school computer nerd literate member of the family who would volunteer to set up for you, then it wouldn't be that hard.

  • do not install USB flash drive

    Hello, my usb flash drive is read as ipod to computer and can access the contents of the disc.

    Hello

    The issue seems to be with the AutoPlay settings. AutoPlay starts playback of a disc as soon as you insert media in the drive. As a result, the Setup file of programs and the music on audio media start immediately. If in automatic execution, the device is configured to be detected as media device it will detect your IPod USB flash drive.

    I suggest to fix the AutoPlay parameter by downloading the file below and check the results: AutoPlay Repair Wizard: http://www.microsoft.com/downloads/en/details.aspx?familyid=C680A7B6-E8FA-45C4-A171-1B389CFACDAD&displaylang=en
