[SOLVED] Can't access external hard drive

wedegnar · 08-14-2009, 01:44 AM

Hello, I changed windows from xp to win7 and now when I try to enter to my external hard drive (which was working perfectly on win xp) I get an error "F:\ is not accessible. Access is denied." Win7 doesn't have access to that hard drive, it even can't run error-check. Any advice?

Hello and welcome to TSF, wedegnar!

Are you the owner of the drive?

Right-click and select Properties. Select the Security tab. Click Advanced. Select the Owner tab.

Thanks, Windy. When I open Owner it says "Current ower: Unable to display current owner." (There are 3 accounts on my pc.) And there says "change owner to: Justas (bendras-PC\Justas)" <<<That's in lithuanian. I tried changing, but it didn't work.

What do you mean it didn't work?:

- Did you get an error?
- Did it just revert it back to it's original settings?
- It kept the setting but you still got the drive error?

It kept the setting after reopening properties tab, but still showed that drive is unaccessible.

Tell me if you need screenshots.

Try:

Click Start, then Run, then enter REGEDIT to open the Registry Editor Navigate to the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class entry
Under the Class entry, double click on {4D36E965-E325-11CE-BFC1-08002BE10318}
Goto FILE and select EXPORT and save anywhere you can remember
In the right-hand pane, click ONCE to select the UpperFilters entry
Make sure the UpperFilters entry is highlighted, press Delete, then Yes.
In the right-hand pane, click ONCE to select the LowerFilters entry
Make sure the LowerFilters entry is highlighted, press Delete, then Yes.
Close the Registry Editor by clicking File, Exit.

Everything is ok, until step 4. There is no Upper or Lower Filters.

Do you know your drives manufactuer, is so, try their website and get a HDD diagnostics test as your HDD may be failing.

Take a look at this post:

Tried Type: FSUTIL DIRTY QUERY F: (where F: is the drive in question). It says I need administrative privileges. May account is administrator. Tried this on the general account, created upon installing win7, says the same.

Still can't find diagnostic tool.

TJ Belfiore · 08-14-2009, 02:40 AM

OH, I forgot to add:

PLEASE, run CMD as administator by right-clicking and selecting "Run as Administrator"

This should help bunches!

wedegnar · 08-14-2009, 02:49 AM

Yes, it helped some. Here is what I get while following http://forums.techarena.in/hardware-...tm#post4131414. See attachment.

My HDD's manufacturer is Lacie, seems that they don't offer any software for diagnostics.

TJ Belfiore · 08-14-2009, 02:53 AM

The correct command is:

CHKDSK /F /R

Enter, and type Y when it gives the Y/N option. Reboot.

wedegnar · 08-14-2009, 03:32 AM

Didn't help.. Typed that in cmd (ran as administrator), rebooted, pc checked the disk, still can't access.

TJ Belfiore · 08-14-2009, 03:36 AM

What's in that HDD?

wedegnar · 08-14-2009, 03:38 AM

Plenty of files and folders. Like pictures, games, music, movies, documents, programs.

TJ Belfiore · 08-14-2009, 03:39 AM

Hmm.. I'll post back in a few, I gotta think.

wedegnar · 08-14-2009, 03:40 AM

Okay, appreciate your help.

TJ Belfiore · 08-14-2009, 03:40 AM

Have you ever fooled with BitLocker?

wedegnar · 08-14-2009, 03:40 AM

BitLocker? I think I've never used that one.
