Specs: Windows 7
I upgraded to windows 7 from vista. I have two hard drives (hdd 0 - hdd 1) hdd 1 has 3 partitions on it.
1 Primary and 2 Logical.
After the install the Primary drive was visible but not accessible.
Anyone know why this is.

You installed Windows 7 to hd1? What was on hd0? Is it still Vista?

Did you look in Disk Management to see if the partitions on drive 1 are showing there. You may need to take ownership of them. Look at the link below.

The partitions on disk1 show up in disk management. At one point the primary drive that I cannot access (drive D:) was set to non active I made it active. I took over the permissions and it still says D:\ is not accessible. Access is denied. The top of the warning box says Location is not available.
The partition shows up under Computer with the drive letter and the drive label.

How does Disk Management identify the file type? NTFS or what? Should state what type of partition and if it is healthy.

What color is the border around each partition on Disk 1?

See if you can right click a partition and choose Explore while in Disk Management.

Cannot explore D: in disk management. Same error.

On disk1

D: drive is NTFS Healthy ( Active, Primary Partition) Dark blue border.

E: drive is NTFS Healthy (Logical Drive) Light blue border.

F: drive is NTFS Healthy (Logical Drive) Light blue border.

That still sounds like an ownership issue. If the drive shows in Computer try right clicking on it there and choosing properties> security. Go from there.

Did you look at any of the hits from the link I posted? One from MS may help.

Have you checked what the BIOS shows for the drive?
Have you tried connecting it to a different SATA port (leave the working drive plugged where it is though)?

Your right.
After more reading and comparing other drives I found I had to add "Users" to the group names in the security tab.
Don't get why this is the only drive that wasn't set up that way.
Thanks for the help.
Vman Out!

That is part of the new security features included in Windows 7. Pain you know where when nothing needs security.
