[comp.sys.atari.st] Turtle tip

rcd@cbnewsj.att.com (rana.c.dutt) (08/01/90)

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.

Or, you can press the ESC key during boot up to disable caching.

No need to load HD Util to enable and disable the cache.  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.
