Can't take ownership after harddrive change
My harddrive was producing an accelerating number of corrupted files, so I moved to a new one before it died. This was a while ago, so I can't remember precisely what method I used, but I think I used a freeware drive-cloner. Some folders were encrypted with Win7's integrated encryption method and I have a whole bunch of exported keys (most of which are probably duplicates),all of which I've run through the import dialogue for.
After "taking ownership" of all files transferred to the new drive, which I did possibly(?) before importing encryption keys and at a high level (the whole-drive? at least, no lower-level than each folder in the drive's root), I can't manage to actually open many of the encrypted files. I've tried this from a non-admin account, using elevated privileges and from an admin account. If I look at the certificate thumbprint of one files as an example, through right-click/properties/advanced/details, then it shows the same thumbprint as one of the pfx files I have backed up on an external USB stick. A few times over, I've imported this pfx file (including to the central trusted repository), or at least seemed to, but if I open the "Manage your file encryption certificates" app, then "select certificate", then none of the certificates listed have the thumbnail of the one I thought I just imported. The files still give a "there was an error accessing this file" error. If I go back to the example file's advanced attributes and try to add certificates, then I get the error "To add users to this file, you must have access to the file and Write or Modify permission for it".
I don't know if this has any effect, but I have the same computer name and username as before switching drives, except that capitalisation of some characters has changed. I also have files which I've encrypted since the move, using a certificate generated after the move, which I can access fine.
