Some recurring failure issues with Win 7 OSD/ZTI during multiple device deployment

Question

I'm currently working on a project to get rid of XP with Windows 7 ZTI using local hard link USMT. Everything is going well for the most part but I have two issues that keep coming up on a few machines.
These are my stats so far:
580 successful with no issue
27 devices USMT loadstate errors (data is intact in C:\UserState however loadstate failed and did not complete the restore or deletion of that folder as it should:
4-5 failure during OS apply .wim step (system is no longer bootable however data is intact in C:\UserState)
A very few machines fail during the Apply OS step. On one machine since I was in front of it I saw this device had some bad sectors on the drive. I manually ran chkdsk to fix the errors and then reimaged it fine.
Since we are doing ZTI remotely we aren't in front of the device to confirm for the other 4-5 this was the same issue on them. I have built in a second attempt to apply the OS with it running chkdsk during the task sequence if it failed on the first attempt.
So far this isn't working to get around the problem on some machines.
This is the command line I'm using from WinPE if Apply OS fails the first attempt:
cmd.exe /c "x:\windows\system32\chkdsk c: /F /R"
If it fails in WinPE I don't have the smsts.log details since we are remote at that time.
Does anyone have any further suggestions on this issue?
Second problem that I see a few every night for example if I deploy to 70 devices I will likely see about 2 with this problem. USMT loadstate failure after OS is applied. The data is intact but not restored all the way. I then have to get a tech to visit
the device, confirm data restoration and then cleanup the C:\UserState folder.
These are some of the common errors from LoadState.log:

I wish I could say the problem was fixed but I'm still having an issue on a very small percentage of machines with last nights deployment of 82 only one had the problem. It's still a very good success rate and the machine did convert to windows 7 just the
loadstate didn't complete. Data again is intact in C:\UserState until it is restored which requires manual follow up by a tech.
From the logs it fails with a domain profile not a local user account as below:

If anyone has suggestions on this it would be appreciated. Thanks
