After reading the comments here, I thought long and hard before attempting to purchase and download from the Intech site. I'm happy to report that there were absolutely no issues with purchase, download or installation. Works as advertised, and the HI Cap driver allowed me to install a new 300GB Maxtor in a Digital Audio G4 with ease. My only complaint is that the guide for the S.M.A.R.T. component is missing. Haven't contacted tech support yet, so I can't comment on issues of responsiveness.
