Messed up Special Permissions for external hard drive

[technostalgic]

Mates,
not able to solve this on my own

I seem to have messed up with the Special Permissions (Properties -> Security tab -> Advanced) for my external hard drive.
I was fiddling with those permissions recently, and now i've noticed that my hard drive doesnt appear in My Computer when connected (though, in USB Safely Remove it shows as plugged in).

When connected to other computers, it works just fine.

I am using Windows 7 Home Premium.

Please help to solve this!

Try uninstalling and then reinstalling the drive.

Bluedot,

didnt understand very clearly what you mean.
It's an external hard drive. So what do you mean by uninstall and then install?
Plugging out and back in doesnt work. Did you mean something else?

The drive is not visible at all, and so I am not able to use the regular method of editing the permissions, and nor can i use the icacls tool.

I dont have a recent restore point, and i'm definitely phobic about a fresh OS installation

open control panel ,goto admin tools ,run computer management tool, in the list on the left select disk management , there it will show you a list of drives, chances are its there without a drive letter ,right click it and add a drive letter!

Thank you tango. Although it wasnt exactly the solution, but navigating to Computer Management helped me accidentally discover that in Device Manager the drive was disabled (although i'm sure i never did that).
So its back and working now, after enabling it from Device Manager

Well, that's pretty much what I meant. When the computer sees a drive (internal OR external), it installs it in the Device Manager. I suggested you to right click on that device IN the device manager, click uninstall and then go to control panel and reinstall the device from add new hardware. Anyway glad to know that your problem is solved.
