Hello, 

 

I just bought an HP Prodesk for the office with windows 7.  Whenever I try anything external (camera, hard drive, flipcam)

I get the same series of errors. 

 

First it says I don't have rights to view it and I need to click on the "security tab" to give myself access. 

Only catch, there is no security tab....(see attached photo). 

 

I did follow the steps here  to make sure I had the tab on and it does appear on regular

folders, just not on external drives. 

Any suggestions?  I'd love to be able to access my external files without having to turn on another computer!

THANK YOU!!

I take it these devices worked on an older computer? Can they connect to another Windows 7 PC?

 

It could be a case of not having up to date drivers for these devices, even though the computer is new (it does happen): http://windows.microsoft.com/en-us/windows/update-driver-hardware-isnt-working-properly#update-driver-hardware-isnt-working-properly=windows-7

 

I notice the drive in question is formatted using FAT32. You may have to go to disk management, and assign a drive letter to it manually: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/i-want-to-acess-my-fat32-usb-drive/cd9d000c-82bf-4fe0-b590-f7597c46cc9e

 

 

If those don't work, and if you're comfortable using the command prompt, you can try running the takeown command on the drives in question. In this case, try opening a command prompt by typing cmd into the search bar, right click and choose Run as administrator, then follow the steps:

 

takeown  /f   DriveLetter:\   /a   /r   /d y

 

Then, type

 

icacls DriveLetter:\  /t /c /grant administrators:F  System:F  everyone:F

 I have 2 desktops with Windows 7 Pro, both with external hard drives attached, but I've never seen this error.  I'd check for malware with Malwarebytes, then boot to Safe Mode and do a full system scan with my antivirus.  If that doesn't help, I wonder what would happen if you clicked the Sharing tab and temporarily gave everybody read access.

 

Good luck.


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

Thanks!  I did run the scan, unfortunately no fix. 

But I did want to add, if I boot up in SAFE mode I can access the drives...just not normally.  

 

sflatechguy:  Thanks!  Perhaps I'm trying it in wrong.  I did open the cmd as admin and cut and pasted: 

 

"takeown  /f   DriveLetter:\   /a   /r   /d y"

 

It gives me an error.  Should I put the "driveletter" as f?  Not sure if I was inputting it correctly. 

Thanks!

 Works in Safe Mode, well that tidbit is very helpful!  Try doing a clean boot and see if that doesn't stop the problem.  To do a clean boot, run MSCONFIG and click the Startup tab.  Note: avoid the other tabs!  in the Startup tab you can uncheck anything there except your antivirus program.  Then reboot and see if you can access the drive.  If that doesn't fix it, there's something we can do with the Services tab, but that one requires more caution, so let's just try the Startup tab first.

 

Good luck.

That would indicate it's possibly a driver issue. Safe mode boots with the mininal system drivers needed. Check the link above on updating your drivers. It may also be a third-party application or an item in your startup menu that is interfering.

If new drivers don't fix it, follow the steps on doing a clean boot to identify the possible conflict: http://support.microsoft.com/kb/929135

Is this a PRO version of Windows 7?

Yes it is windows professional 64. 

I'm doing a couple updates now.  It seems unrelated to the issue, but I'll update them anyways.

I initially was thinking you could change the setting in Group Policy to disable deny access to Removable Storage Classes but I found something regarding HP Pro Books. See if this solves your problem. Look at HP Device Manager if  you have it. It could be some other HP software denying access.

 

http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/Access-Denied-on-USB-drives/m-p/3669132#M189675

 

If the above solution does not work, Change the setting to disable deny access as shown here. If the setting is "Not Configured" change it to disabled and reboot.The link is for Vista but same applies to Win7

 Yes, you want to put in the drive letter as in F:

Give that a shot -- but I suspect it may not work, as you are able to access the drives in Safe Mode. That indicates a driver or application is preventing you from accessing the devices. And I think JohnC_21's link may have hit on the issue. It certainly would save you the hassle of going through the clean boot process.

John did get it!  

I uninstalled that program (click on HPs bubble to get access to drives) BUT my computer must have restarted before it was finished.  

 

So it was creating an issue.  I re-installed...then re-uninstalled and it worked. 

Thank you!

Great. I figured it would. The first command line command I gave you would have reset the file and folder permissions for the entire drive, the second command would have reset the Discretionary Access Control, another set of permissions that, in a way, determines whether you have "clearance" to access to that resource.

 

But because you could get to the drives in Safe Mode, I knew it wasn't a permissions issue. The application was blocking all access to the drives, so you couldn't even have changed the permissions if you wanted to.

 

Glad that got resolved. :cool:

'Virtual Disk' service was started or not?

Make sure it was started.

Thank you John!!!! Created an account just to post... I've got 20 years of IT experience and this STUPID IDIOTIC HP Device Manager was my problem too. No error, no warning, nothing but blocking USB access. So happy with this forum and so map at HP - PITIFUL
