Help please regarding non responsive external drive

Hi
I've had two external hard drives working side by side on my pc for months. This morning however one of the drives is just non responsive. I click on the icon in My Computer and it says that the drive "is not accessible, access is denied". When I click on properties for the drive, the pie chart is showing 0 bytes used space and 0 bytes free space. I've tried unplugging the drive and also switching off at the power point but with the same result.

However if I plug the same external hard drive into my laptop it works fine with no problems at all.

Any suggestions? I'm using Vista Home Basic on my desktop.
Any suggestions greatly appreciated.... thanks.

Yeah fine, I've switched both hard drives to each others usb ports and this hard drive is still unresponsive. Weird that it works perfectly on my laptop. Nothing lost I suppose as I can use it on there but do need it more on this desktop.

are they both called f: drive by any chance ? windows has a habit of naming drives with the same letter and so you cannot access one of them

on XP

control panel > admin tools > computer management > disk management in the list on the left. here you can see all your drives and the letters asigned to each one

All the drives are showing up correctly, one is the J: drive and the other is K: drive. The Maxtor Basics works on my laptop which is running XP but not on this desktop or another desktop I just tried which are both running Vista. Seems therefore to be a Vista problem but I got no idea how to even try and correct it.

Usually a driver has become corrupt and is pretty easy to correct,With the drive unplugeed go to device manager,
control panel
System and maintenance
device manager,
now click on the cross next to universal serial bus controllers.
Look for Usb mass storage device
If there are any there double click them and under the general tab look for location and
write down the port number ,Do this for any mass storage drives you see as these are the ones you want to leave alone,Now plug in the dodgy drive and a new one will appear in device manager,Double click it to and make sure it has a different port number to the ones you wrote down,When you are sure you have the new drive click on the driver tab and uninstall,when you have uninstalled remove the drive and restart your pc,then simply plug the drive in again and the drivers should be reinstalled

Many thanks for that, will give it a go once I've got rid of my visitors.

One thing though, when I tried this device in another desktop running Vista, it initially came up as saying that it was installing drivers and then installed successfully but when I tried to access the drive I got exactly the same message as on this desktop ie. drive is not accessible.

What I'm trying to say is that if I get the drivers re-installed on this pc, I think it's still not going to enable me to access the drive. It's weird how it still works on XP though.

Thanks for your help btw.... will rep you. :thumbsup:

When you click right click on the drive and click properties is there a security tab ?,If there is then follow these instructions

Currently trying this and it looks promising! I'll get back to you. Currently going though "setting security information" on the disc. May take some time as it's 500gb worth! Thanks again. :thumbsup:

Nahhh still no luck! :cry:

Do I need to try that with "system" highlighted? I done it with Administrators highlighted. When System is highlighted neither the allow or deny tabs are ticked. Confused? I am! :thinking:

Yeah i think when you click system they should all be highlighted,Are you right clicking on the drive in my computor ?

Try start again,Go to My computer
Right click on the drive
click properties
click the security tab
click edit
click on system
higlight all the allow tabs except special permissions
click apply
done
also check that the same are highlited for administrator

Done all that and as you say, all are highlighted but still can't access the drive. Just get the same box saying: - Location is not available, k:/ is not accessible, Access is denied

It's obviously available as it's just spent the last two hours going through every file on it, putting the security access on every one. I've seen every file named and scrolling before my eyes.

Maybe I should just give up! :?

This is sounding EXACTLY like an ownership issue (you need to take ownership of the drive in Vista).

see ]here there are 2 ways of doing this described in the link.
