Cannot access partition after recovery

Hi,

I've shrunk the OS partition to make room for a D: partition on a M4700 laptop. All went well, and I've used it in that setup for a while.

Recently, I had to reinstate to factory image. Again all seemed to have gone well. My lap top is in "as new" condition, but I can't access my D: partition.

I can see it in the Computer Management, but I can't do anything with it. It says "healthy (OEM partition), but when I right click over it shows a link to "help", but it's a rather unhelpfull help!

Any suggestions on how to get my D: partition back? I'm fine with loosing all it's contents. It's backed up safely.

Thanks!
