Access is denied in Vista

I'm trying to use my Seagate External HD (worked fine with XP), but on my Vista computer it just makes clicking noises and is not recognized.

I did some searching on the Internet and someone found that deleting a file INFCACHE.1 solved this problem.

I tried deleting the file, but the system won't let me - I don't have permission. So I tried giving myself permission (I'm the administrator and the only user), but I get an error message:

An error occurred while applying security information to Windows\inf.

Access is denied.

Help!!

My experience has always been that when ext HD's click it's because they are not getting enough voltage/amp.
Usb 2.0 is a lot more strict on the voltage/amp than the version 1.1 and will not let devices draw more than it should. I am sure Vista is adhereing to the USB standard more closely too.

To solve this I would get an external power source or get a double ended usb cable. the device side is normal but the PC side has paralleled double connector to be able to draw power from 2nd connector. My Maxtor Mini 60gb came with one. The 2nd end does not let data go through it ,only power.

Logon with THE Administrator account. THE Administrator (note the UPPERCASE 'A') is different from a local account that can run programs as *an* administrator (note the lowercase 'a')

Follow the steps here:

create a text file called Ownership.reg and add
this


Windows Registry Editor Version 5.00


[HKEY_CLASSES_ROOT\*\shell\runas]
@="Take Ownership"
"NoWorkingDirectory"=""

[HKEY_CLASSES_ROOT\*\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"

[HKEY_CLASSES_ROOT\Directory\shell\runas]
@="Take Ownership"
"NoWorkingDirectory"=""

[HKEY_CLASSES_ROOT\Directory\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"


This will give a right click option to take ownership of any file.

i would check if it is still ok on your XP system - it seems bad.
if so, take the drive out , and hook it directly to the ide /sata connector of the pc, and test it :

Plugging in both ends of the USB cord did it. The drive is now recognized, but I cannot safely remove it. I keep getting an error message that some program is sitll using it - no program is using it as far as I know...

The Real Admin log in is very useful, too! I will definitely need it.

The hard drive are likely stating the warning because there is a process accessing them. Such as a security program, Norton, Zonealarm, MaCafee etc... or its just plain explorer.exe.

If you use AUTORUNS in combination with PROCESS EXPLORER you should be able to determine which is the culprit. Both programs are free and actually can work in conjunction with each other.

>>>AUTORUNS in combination with PROCESS EXPLORER

I downloaded both programs and nothing is accessing my external drive. All my processes are running on C:


http://safelyremove.com/?pid=1     

This doesn't let me remove it, either. It tells me something is accessing it or another user with more privileges is using it. I logged off as the Admin, I'm the only user logged on now. What is happening?

What is on the drive? I don't think its too horrible to go ahead and yank it out.

The processes are running on C but one of them is accessing your external drive.

It's my old back up drive. I would not want to lose any data, even though it's not critical. I also don't know if the drive could be damaged this way.

How can you tell which process is accessing my external drive?

YGregersenCommented:
Are the lights actively flashing and hard drives working away - likely not. Unpluggiing will not kill the data. If it is doing stuff let it finish before unplugging.

Likely, something has scheduled it as part of some scan and the drive is on 'hold'.

*** If you are really worried, shutdown Windows then unplug it.

No biggie. Glad to be of help.

I'd like to hear what the maker of safelyremove has to say. Could you please post it even though I'm closing this question?

Thanks for lots of good info. Everything helped. I wish I had more points to give away.
