External Hard Drives

[SusiePat]

I have four external hard drives attached to my pc. Only 3 of these are showing in my computer. Does anyone know why the 4th one is not visible. I have checked all the wires and they are all connected correctly. Can anyone help me wih this please Thank you

Has you seen all 4 before?
Have you tried unpluging one that you can see & plug the 4th one into that now empty port.

This is a new hard drive which I have just connected the 4th one to my pc. I have tried switching off and on again and I have even taken out all the leads and connected them again but they still don't show.

Unplug all the hard drives...then plug in the new one..then can you see it.

I have tried unplugging and plugging in again but it still isn't visible. If i unplug one of my others and plus new on in then it does show but the one I took out doesnt.

Ok what i suggest is you check Windows hasn't got your device drive letter confused and is finding it conflicts with a device already plugged in.

CLick on the start button
Select 'run'
type 'Compmgmt.msc'
hit enter

You should see a computer management snapin pop up

Look down the lefthand side for 'Disk Management'

Each disc should have a brief description and a drive letter C: D: etc.

If you see one without a letter right click and select "change drive letter and paths' (Or check to see if there's a warning about the partition on that disc. )

Add a letter and click ok.

Goto explorer and look for drive letter you just assigned.

Otherwise disc could be shagged and i hope you dont have any important data on there. (see get a Nas thread!)

Could it be you have taken your computer to the limit of the number of peripherials it will support?

I have opened the computer management. All the drives are showing but I have noted that all are quoted as online apart from one which is Offline, when I hover over this there is a message "The disc is offline because it has a signature collision with another disc that is online".

Thank you very much, you are wonderful, this is now showing in the list on My Computer. I have also changed all the letters to they run in sequence. Thank you again.
