Problem with upgrading iastoa.sys

I upgraded my iastora.sys file after receiving notification that there was a conflict with WIN 10 upgrade. Before the upgrade I had a partitioned drives C, D, E. Problem after the upgrade is that D drive doesn't exist and is shown as E drive ( simple- basic-NTFS- healthy- 945.52 capacity- 691.86GB- 73%. some programs like screen capture is asking me to insert disc when before it was running off the D drive. Under Disk Management D doesn't show up at all. How doe I change E to D when D doesn't show up in Disk Management. I have found Drive D but it is now associated with the DVD drive and that doesn't show on the Dist Management. So I don't no how to change it back

How did you resolve the issue with Iastora.sys? Did you install a different version of IRST?

Please post a screenshot of your disk(s) using Minitool Partition Wizard (free).
To post a screenshot please use the Insert Image icon above your post

that tool can hide/unhide partitions, if that's what's happened.

Unfortunately the free edition does not support partition recovery. It may be worthwhile finding a tool (freeware?) available to you that can scan for and recover lost or deleted partitions.
