hi following this thread from igazsa Posted: in another forum. "Finally got it working, It all came down to the ASPI problem that there are various threads about - ended up copying the Nero version of wnaspi32.dll to the winnt\system32 folder and it now works a treat".
I am running ASPI 4.72a2 on Nero 6. I did as suggested and copied the Nero DLL, into the windows directory. I now have access to both my external drives. I have tried this forum and many others for a fix, now we have one.
