More info?)
Per my previous post, in a 2805-S202, I also get an "IDE #1 Error" on
powerup with a Toshiba SD-R2212 drive installed. I can't boot from the
drive, but within Windows, it is detected and works properly in all 3
modes (CD, DVD, CDRW burner).I have more information on the "IDE #1
Error" problem when changing the optical drives in many Toshiba (and
some other)laptops. Note that I have not yet actually tried what
follows myself.
Apparently jumpering pins 45 & 47 fixes the "IDE #1 Error" problem in
many/most cases. Pin 47 is "cable select", pin 45 is ground (note, pin
48 is also a ground, but 45 & 47 are right next to each other); I'm
getting conflicting information about whether this mod makes the drive
"master" or "slave", but I'm finding lots of reports that it does
resolve the problem with a whole lot of both different notebooks and
different drives. The jumper may be installed either in the drive or at
the drive connector or on the laptop motherboard.
The connector is a Japan Aviation Electronics Industry Limited
KX15-50KLD L; it has 50 pins in 2 rows of 25 pins each. There seems to
be a multi-vendor informal standard for the use of this connector in
laptop optical drives, pin #1 is towards the edge of the drive, pin 50
is towards the center of the drive, one row contains odd pins 1-49, the
other row contains even pins 2-50. However, the one thing that I have
not been able to find out is how to clearly identify which row is the
odd row and which row is the even row. I believe, however, that the row
towards the drive circuit board is the even row (which is unfortunate,
because it's easy to get to the pins, while it's the odd row that you need).
So, if I have this right, you need to jumper the 2nd from the end pin on
the top row to the 3rd from the end pin.
From your post:
Region-free stuff, and some bits of info,

An adapter for connecting a laptop optical drive to a standard 40-pin
IDE port can be found here:
http/www.bixnet.com/notslimcdtod.html
Note, this adapter would be for some other use. The jumper to CSEL pin
47 (not the last (left-most) pin, but the next to last) is installed
permanently, not "one time".
If you get any further information on this, I'd appreciate learning of it.
