Can't access second hd in Vista

[Haroder]

I have just installed Vista Home Premium on a system with two sata drives. This is a standalone installation (no dual booting).
Both drives are recognised in BIOS.
Device Manager lists both of them as basic, on line and working correctly.
Both discs appear in Disk Management as healthy, primary partitions (both drives are 80GB and not partitioned) and labelled Disk 0 and Disk 1. Disk 0 is labelled as C: Disk 1 is not labelled. Right clicking Disk 1 allows me the only option to Delete Volume, all other options are grayed out.
Disk 1 does not appear in Windows Explorer and I am unable to access it.
I have just spent four hours searching for a solution with no success.
Please, will some kind person help me out here?

Thanks for reading.

Did you install them in a Raid mode?

Thanks for your interest Underclocked. The answer is No Sir, definitely not.

I am pleased to say that I have solved this problem although it was more luck than management.
I took the bull by the horns and deleted the volume. This really screwed things up so I hit System Restore whereupon it reappeared as an unallocated disk. It was then just a matter of formatting it.
Thanks again for your interest.
I would have marked it solved but haven't figured that bit out yet.

Sounds like VISTA is seeing Disk 1 with a "hidden" partition or something on it that looks like a partition that is hidden and/or not formatted. So if Disk 1 is "80 GB and not partitioned" then there isnt anything on it that you have any interest in. Just delete (using FDISK) the volume, create a new partition & format it.

Before doing this, if you want, check the status of what's on Drive 1 using FDISK or some partitioning utility such as partition commander. Especially if Disk 1 was the result of an image made from another HDD, then usually the copy image is marked "hidden". Otherwise, if there is nothing on Disk 1 then just delete the partition & create a new useable one.
