I'm trying to test Windows To Go, and am using a My Passport Enterprise drive. I did not see Western Digital's instructions, where they specifically mention running a WDCompass.exe before applying the WIM to the drive.

So, in my case, I've been able to boot off the external drive (with some mixed results), but performance is poor, and the OS seems to randomly cause reboots. While I'm not sure if this utility would help, the above link specifically mentions the time of applying the WIM to the drive is reduce by 2/3 to 3/4, which suggests performance may be better.

Unfortunately, as I've already applied the WIM to the drive, I no longer have the WDCompass.exe, and I can't seem to find a download link for it. Is there any way to get this utility?

I would contact Western Digital support staff, any link we provide you, would either be found on Wester Digital's website or a third-party website. –  Ramhound Nov 2 '12 at 20:00
@Ramhound yeah, I've opened a support case . . . not sure how responsive they are, so we'll see if crowdsourcing or dedicated support wins out . . . –  ernie Nov 2 '12 at 20:08
"Double-click the WDCompass icon on the desktop to open a Command window and verify that at least one successful modification is indicated" - I wonder what the modification is? If it's just something to the partition table/bootloader, it could be replicated by other (Open Source) utilities. –  Karan Nov 2 '12 at 20:10
@Karan I wonder that too, though it looks like from the last screenshot that it changes the "Ignore Flush Cache" bit? –  ernie Nov 2 '12 at 20:12
Yes, I didn't see that one. I'm sure the ability to do this will be replicated as soon as someone compares the drive before and after. Till then, guess WD is the sole source. Edit: They should at least have uploaded the software here (maybe they're just lazy and plan to do it soon). –  Karan Nov 2 '12 at 20:13
