I originally posted this in response to a thread created by JAG13,
Removing 16MB SanDisk, 03-18-2000 08:33:43 A.M., which is now archived
in (Old BBS posts, READ ONLY area).
Apparently there still seems to be an issue of how to electrically
disable the SanDisk. I an now posting it here for those who haven't
the ability, or the desire, to work and read.
Extracted from the following document on SanDisk's website.
SanDisk Flash ChipSet
Introducing the world’s smallest ATA/IDE data storage system.
The SanDisk Flash ChipSet (FCS) is the world’s smallest resident
solid-state ATA/IDE data, image and audio storage system. The FCS
consists of a 100 pin TQFP controller chip and flash memory in a
56 pin TSOP package.
Memory Mapped Mode Support
The memory mapped mode is the default power-on mode for
the SanDisk Flash Chipset if the "OE" pin is not grounded. This
mode provides for a simple, straightforward interface to the
user’s hardware. It is particularly applicable in embedded 8 bit
microprocessor applications, since 8 bit data transfers can be
accomplished without issuing a command to the Flash ChipSet.
IDE mode True support.
The SanDisk Flash ChipSet may be configured in the
True IDE Mode by grounding the "OE" pin. This provides
the same interface as that used by IDE hard disk drives.
The IDE interface is very simple, requiring a minimum of
hardware and software development. Because this is an
industry standard interface, in many cases the hardware
and software are built into the host system. This mode
also supports 8 bit data transfers after a “Set Features”
command is issued.

If you have no idea what this means, you would be best to stand
clear of any such modification. Otherwise... Enjoy.
Please feel free to elaborate.
I've pointed you in the proper direction from the word GO.
I did get a good chuckle from all you clowns who physically ripped out
the SanDisk by brute force using a Dremel Tool and/or Exacto knives.
