Every recording I've ever made with the 744T has been recorded both on the internal HDD and CF card. I've always taken the CF card and plugged it into a cheap (but seemingly reliable) CF reader and then dumped the files to my laptop via USB. I typically keep the raw files on the 744T HDD until I've copied the raw wavs to external HDDs and mastered/tracked the files.
Are some of you suggesting that a CF or other card reader can be unreliable and introduce errors? I've never noticed anything when doing so and any issues (e.g., static, channel drops, etc) I've noticed with files coming from the CF card were also on the files on the HDD clearly an indication that the CF and/or reader were not the issue.
