Darren, The reformat should not impact your audio drive since it's a separate drive. ----- Original Message ----- From: Darren H To: ddots-l@xxxxxxxxxxxxx Sent: Sunday, November 21, 2010 5:50 AM Subject: [ddots-l] Which version of Window 7 Hi folks. As some of you will know, I've been having terrible issues with jaws and my recently repaired system. I've decided to bite the bullet and reformat the hard drive and start fresh. Baring this in mind I've decided to go with Windows 7 for the new install. Is there any particular advantage to getting Profession or Ultimate over Home Premium as most of the differences seems to be with security and networking, which won't be necessary as it'll hardly be connected to the net or the home network. Also, my system has separate drives, the C drive where the operating system is installed, and audio drive where sample library and CakeWalk projects are stored. When I do the reformat, will the audio drive also be formatted? The audio drive is not external. I'll do a full back up of the audio drive in any case, but I'd just like to know in advance what to expect. Thanks in advance. Cheers Darren www.karmistry.com
