I bought a new external hard drive (WD Elements Portable); after plugging it into my Windows XP SP3 machine (a Dell Vostro 1015), the following message pops up:

Windows could not load the installer for volume. Contact your hardware vendor for assistance.

The hard drive works without any problems on a Windows XP SP2 and Windows 7 machine.

Any thoughts how to fix this?


Go to C:\Windows\System32 and rename sfcfiles.dll to sfcfiles.old. Next try copying the sfcfiles.dll file from C:\Windows\ServicePackFiles\i386 to C:\Windows\System32.

The one in that folder should be the latest version, but if that doesn't work, do a dir sfcfiles.dll /s from a Command Prompt in the C: drive root to find other versions. This worked for a number of people in this thread:


  • There was no sfcfiles.dll in system32 at all, so coped from C:\windows\ServicePackFiles\i386 and hdd mounted! Thanks :) – lfx Jul 16 '11 at 12:27
