Those of you using Turtle 3.0, George Woodside's excellent hard drive backup utility, may already know that it is incompatible with CACHEnnn.PRG. Many people have CACHEnnn.PRG in their AUTO folders to take advantage of TOS 1.4's disk caching capabilities. I recently bought an ICD hard drive, and was surprised to find that Turtle gave me a fatal error message, even though I had turned off CACHEnnn.PRG. After much investigation, I found that the ICD hard disk driver, ICDBOOT.SYS, was the source of this new incompatibility. It turns out that my ICDBOOT.SYS was pre-configured to allocate blocks for read/write caching. I fired up HDUTIL.PRG, and re-configured ICDBOOT.SYS to disable all caching. Doing this made Turtle happy. I could then back up my hard drive. After that, I re-enabled the ICD caching, and CACHEnnn.PRG. I hope this helps other Turtle users who own ICD drives.

Just turn it on, and when you want it disabled, hit ESC after ICDBOOT displays its version number on boot-up (and before it lists the cache stats). (What an ugly sentence, but I hope it got the idea across.) This will temporarily disable the cache.
