Windows 7: windows repair and windows disk manager show different drive letters

Your problem really appears to be that an existing image on an external HDD cannot be auto located correct?
That is correct. The usb drive can not be found.
I have never been able to find the usb drive in the repair enviornment.
I've have tried usb 3 and usb 2.

It appears the problem is with my WD my book usb drive. I plugged in a Seagate Free Agent and it showed up in repair and all seams to work fine. Although the WD usb drive came formatted should it have been reformatted?

You don't need to format the drive if it works fine in Windows.

It is a known issue with some external drives and winpe - WD in particular.

My experience: WD externals such as My Book essentials can go to sleep on you during a live boot.
Check if the recovery environment (system repair disc??) can see the external disk. One way
- go into command prompt
>list disk
.....see the disk??

If no then first try a USB 2 port.
- get to the image recovery search stage
- Unplug ext HDD power and USB. While in live boot mode of course. Don't do this if the HDD is detected and especially when data transfer is underway!!!
- Reconnect both and look for any signs of life - HDD LED flashing
- keep trying "Retry" and see if the auto locate picks up on the image.

Now the Image folder must have the exact name
live in the root of a partition on the ext HDD.

If this works all you need to do is load the USB 3 drivers as part of the process to get the much faster usb3 capability.

If Yes. Then it's an issue auto locating a Windows image. In the short term (or long term!) use free Macrium Reflect V5 and see how you go. This is good reliable software.

I'm lucky both work fine for me. I use BOTH and don't trust a single package for something as important as imaging.
Note the WD drives can go to sleep regardless of what's on them in live boots.

Using a usb 2 port I was able to get the WD usb drive noticed. had to unplug and reconnect then click retry several times to finlay get it to auto locate.

How do I load usb 3 drivers? Cannot find any nusb3 inf files only sys files that will not load.
maybe I need to get a drive that will not sleep. This drive maybe destine for the trash can.

I found ( by chance ) nusb3.inf file in C > programs x86 > nec electronics > usb3 host controller driver > driver > x64. copied all files to flash drive and booted into repair. selected load drivers and migrated to the flash drive and selected the nusb3hub.inf file. A window with three drivers popped up. one was usb 3 host controller, one usb 3 hub and one standard usb hub. I selected usb 3 hub and then install. the install took a few seconds and in the process the usb drive started flashing. finally the back up file was identified. Seams MS and/or WD could have made this a lot easer. If the usb 2 drives can be auto located the usb 3 drives should be also.

Thanks very much for you'al help! I have searched and read for a couple of days and was getting no ware but very frustrated.

Re drivers you need the .inf I believe like I show here
Problem recoverying from backup via USB 3.0 external drive
Go to your Motherboard Website.

As far as trashing the drive that's up to you. I knew the issue after my first purchase but still bought a 2nd. 1TB USB2/3 for $79 at the time - just a little more than the actual sata drive inside. The live boot issue may be a bit of a nuisance but a replug always works for me (when needed).

I wish WD would stick to HDDs and leave software alone though.

Edit: just saw your last email. I'll leave the above in case it's useful for others. Looks like you have it working??
