Solved Quicktime install corrupted data drive

[marcusbmg]

Yesterday tried to install apple quicktime. Install failed and then I started having problems with the D data drive: "inaccessible or corrupted" messages.
I can still see the folders, files and structure in file management. However attempting to move or copy anything fails. On boot win7 advised to check drive but that didn't work.
I ran western digital diagnostics off UBCD rescue cd, short and long tests no errors. Then I checked the win7 install with System File checker - no problems (didn't expect any, win7 boots fine). Then I tried chkdsk D:
This swiftly returned "orphan file found can't continue..." chkntfs returns "D is dirty.."

Now I am worried that if I run chkdsk /f this might be a disk wide problem and everything is going to become a .chk file
HELP advice needed!
I should add that I looked at system restore but no restore point was available prior to the apple install attempt - not sure why!
Should I attempt some data recovery first? I have a backup (paragon image) but it is a month old (due to this PC being a recent build and dilatory in setting up regular backup).
So I am hoping for some good advice from members more expert in working with ntfs problems like this...thanks:sarc:

I've always found Quicktime highly annoying at best and instead use either Quicktime Lite or Quicktime Alternative, neither of which have ever caused a problem.
