Couple more points:
(1) There are 52 hours of HD space on the ML9600 at redbook spec. So if you wanted to you could make programs. I don't but you could.
(2) There is a company making mods (Alesis tech support could tell you details) whereby additional HDs can be added, outboarded. I'm sure this voids the warranty, but if that's what you need....
(3) Better solution for long-term archiving and making programs, and.or copying etc is the ALESIS HD24 or HD24XR. Both are HD recorders, which will default to 24 tracks, not necessary for my uses, but you can tell it "no, I want 2 tracks" or whatever in between like 6-8 etc. etc. The HD24 will do up to 48 KHz smapling. The XR will do up to 96 KHz. You can edit, move, assign screen names, create projects into which you can place various albums. The drives are cheap and sit in "caddies" which are removable and store in a "library-type" case. Here's the link:
Link to HD24 HD24XR I'll try (first time) to post a pic. Here goes:
