Rrrr,

I'm trying to swap a cd-rw/dvd-rom (Tosh SD-R2512) for the original cd-
dvd/rom (Tosh SD-C2502). Laptop is a Satellite 1805-S254, XP Pro.

With the v1.8 bios I get an IDE#1 error and the burner isn't detected
in the os. Changing the bios all the way up to the last available,
v2.10, the thing won't boot into the os. When it hangs, the cd tray
will open as if it's detected.

On a dvd forum there're hacks offered for making the dvd region-free,
and suggestions for changing the cd-rw firmware to rom ver 1720. But
nowhere have I found *that* firmware. It's currently set at 1020,
according to the label. I really don't care about region-free, I just
need to get the unit detected.

Someone else, with a similar Tosh laptop- different cd-rw, said they
got an IDE#1 error but their cd-rw was detected and functioned in spite
of it.

I've ordered a mini-to-ide adapter to determine if the cd-rw is
defective or not.

Anyone have any suggestions? Thanks.

I think I'm the "other guy" you refer to.

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).

If you get any further information on this, I'd appreciate learning of it.

Found this on a web search for "Toshiba IDE #1 Error":

"I then found some info. but it was German so I tried to have had it
translated and then worked out that if I connect pin/connectors 47 & 45
together it solves the poblem. Drives have no IDE #1 ERRORS and were
succesfully flashed to RPC1 (Region free)."

Apparently, jumpering pins 45 & 47 sets the drive to slave. I've found
multiple references to this, many people are finding that it does solve
the problem on many models of Toshiba laptops (and some reports with
Sony laptops also), on many models of different DVD/CDRW drives. I'm
looking for a drawing of the pinout of the drive. Apparently there are
JPEGs floating around of what you have to do, but I have not found them.

Thanks Barry, I think you're right about you being the source. <g>

The 2512 has a decal with pin positions on it.

Region-free stuff, and some bits of info,

http://forum.rpc1.org/dl_firmware.php?category=15&manuf...

Newegg pic of drive:
http://images10.newegg.com/productimage/27-130-023-02.J...


The far upper left pin is marked CSEL, pin 47 or 48. I don't have the
drive in front of me. I'm trying to do this for a buddy. I'll get a pic
of it, or a better description of the decal, but later today.

I might redo the bios to v1.80, install the cd-rw and see if I can get
XP to detect it in _that_ device manager. I'm not used to XP yet.
<oye!> It boots with the earlier bioses but wouldn't with the latest.

As far as jumpering, I think it needs to be jumpered to Master, but
the bios is so bloody bare. And how would you figure to jumper it?
Cold? Or with power, 5v or 12v? <shudder> I've got a bunch-a-time in
this already. <G>

Looking over your post it appears that maybe pins 45 and 47 are
jumpered while also using the mini to ide adapter I mentioned. In a PC.
That looks damn tough to do, those connectors are tiny.

Thanks for your reply.

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,

http://forum.rpc1.org/dl_firmware.php?category=15&manuf...

Newegg pic of drive:
http://images10.newegg.com/productimage/27-130-023-02.J...

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.

(mailed and posted)

[Hope you get this pic. SD-R2512 decal.] I mailed the pics (2) to your
email. Otherwise I could post them to some binary ng.

Took the cover off of the drive. If a jumper is the only thing needed,
the connector on the board had exposed flat wires (that feed the 50
pin).

Raised up like inverted little "L"s, typical of alot of comp
connectors. I imagine the jumper could be soldered to the inside, which
would be much more reliable IMO.

Also, the dvd-rom I removed is marked as M/S for pin 47. The cd-rw/rom
is marked CSEL, pin 47.

I'll chase on Google myself now. I'd like to see some verification for
the jumpering.

I left a report on the Newegg page, but they seem to have filtered it.
How nice of them. Grrr.

The adapter I mentioned is used to install the slim drive in a very
small-form case. I suppose that's all.

Ok, I made the modification and it did indeed fix the "IDE #1 Error"
problem. I made it the way that the guy did in the picture, exactly --
a "solder bridge" (blob) between the two pins. All fixed now, can even
boot from the optical drive again. So it's definitely a master/slave
issue, the drive is not configured in a manner compatible with many laptops.

http://216.239.39.104/translate_c?hl=en&u=http://www.ds...

WARNING: Making this modification requires not only soldering, but
EXTREMELY fine soldering. Most users will not be able to perform this
on their own. The pictures are deceptive, these pins are only a couple
hundredths of an inch wide and a couple hundredths of an inch apart.

Going over the dschen site, the pin-out description at the very bottom,
it appears that making #47 open would create a slave setting and
soldering #47 and #45 (gnd) would set the drive to master.

I'm sure the one I have needs to be set to master as you have done
with yours. I guess I'll have to take the chance that the drive will be
detected in XP. It is detected at the bios level, it's listed as found,
but that's as far as it gets.
