External hard drive (new) enclosure and Vista problem

By donnaandneil ·
Hi,

First of all Im not big on technical hardware issues but today I bought a Samsung 160gb external hard drive (in an enclosure) for my Toshiba M200 laptop which is running Windows Vista basic. Although Vista detects and installs drivers for the hard drive..the drive does not appear in 'Computer'. I go to 'Disk Management' and I am unable to intialise or format the drive. The drive appears as unreadable and unallocated. I right click on the unallocated area and I dont get any other clickable options other than properties or help. The 'New Simple Volume' option is unclickable.

Can anyone help me fix this problem?

This is a well known Vista Issue

What you need to do is format the Drive in the Drive Management and that should not only allow the Vista OS to see it but allocate it a drive letter and make it available for use on that computer.

Just a word or warning however once you make it readable on this computer the possibility exists that it will be unreadable on another. So if you are saving any critical data to the drive you need to keep this in mind.

unable to format

Thanks for your reply. There is no option to format the external in Disk Management. I right click on the area which reads unallocated and I can only click on properties and help. I dont understand why I cant even format the drive?

Are you logged in with Administrator Rights?

by OH Smeg In reply to unable to format

Or is this account a Limited User Account? That would be my first thing to look at here. If you have a Limited Account you need to log in with Admin Rights or disable the UAC to give you Admin Rights.

yes

My account is an adminstrator acount. It doesn't have any limits on it. I'll try disabling the UAC though but I think I already have admin rights.

Any other ideas?

Well if you have a Admin Account

by OH Smeg In reply to yes

When you click on the Format Option you should be prompted to type in a Password to grant you Admin Rights. If the box isn't active or you don't get prompted for the Admin Password you don't have an Admin Account.

I have admin rights but no format option

Hi,

I am logged in as admin with full access rights but there is no option to format the drive. All I get when I right click on the unallocated space for the external drive are clickable 'properties and help' options.

If you've solved this, then ignore, problem is with PL-2506 controller!

by cerealdud In reply to solvable?

Not sure it is solvable.

Is the enlosure based on PL-2506 chipset-controller?
2nd, are you running Vista 32?
If so, the following info may or may not help. I was running Vista 32 at the time.
While attempting to access the enclosure with an IDE hard drive enclosed, I received the following error code :
""Compatibility issue between Windows Vista and PL-2506 Hi-Speed USB-to-IDE controller."
The error message also says, " Prolific Technology, INC., the company that manufactured the PL-2506 Hi-Speed USB-to-IDE controller, has informed Microsoft that they do not expect to offer updates to fix this problem. " This was under Vista 32. Unless MS releases a driver patch to address this issue, there is little chance this will ever work under Vista. I also, haven't gotten it work under XP. I am not sure if this version of XP has updated to the point it will not work with this chipset.
3rd, you may have to do some homework on what chipset your enclosure uses.
If possible, I would try to find a enclosure not based on the PL-2506.

Same Problem - Help?

by lozzbyrne In reply to External hard drive (new) ...

I managed to get one step further I think... and managed to get Vista to think it could inititialize the disk.. but then received another Error.
Unexpected failure. Error code: 45D@0200001A
I'm am demented! The drive worked fine a couple of days ago. I have yet to find anyone with a solution to this...
My email address is lozzbyrne@hotmail.com
Thank you!
Additional details: It is not a power supply/cable problem. It is not a disk letter allocation problem - that used to be fine at G:/ - I am now unable to allocate a letter. The disk appears in Disk Management as unallocated and unreadable.
