I have a problem which I think is in Rainbow TOS. When I format disks with Rainbow TOS it quite often happens that my ST2 that is running TOS 1.2 can no longer read the disk when it has become somewhat filled. The problem doesn't occur with our 1040's. Is there anyone who has some idea about what might be happening? Werenfried Spit R.J. v.d.

Perhaps it's out of alignment, or the drive speed could be off by a couple of RPMs. Rainbow TOS 'twists' the disks when it formats, to gain increased speed. I used this when I had my 1040 (TOS 1.0) using an auxiliary formatting program. You may want to try formatting the disks with a formatting program, instead of with the desktop, and see if there's any difference. -- Ed Krimen ............................................... ||| Video Production Major, California State University, Chico ||| INTERNET: ekrimen@ecst.csuchico.edu FREENET: al661 / | \ SysOp, Fuji BBS: 916-894-1261 FIDONET: 1:119/4.0

On my mega2, I could not get a reliable backup of my HD onto floppies. The symptoms were "bad" spots on floppies that moved tracks, disks that were readable then ureadable and then readable again without any changes to the system. When I got an external FD, all my floppy problems "went away" as long as I stick to the B: drive. > > > -- > Ed Krimen ............................................... > ||| Video Production Major, California State University, Chico > ||| INTERNET: ekrimen@ecst.csuchico.edu FREENET: al661 > / | \ SysOp, Fuji BBS: 916-894-1261 FIDONET: 1:119/4.0 -- ... ^^^ eric johansson UUCP ...!uunet!wang!harvee!esj esj@harvee.uucp * * a juggling fool AT&T (617) 577-4068 (w) o HAM ka1eec \_/ CSNET johansson%hydra@polaroid.com or hydra!johansson@polaroid.com source of the public's fear of the unknown since 1956
