The Firmware Page

i think i wrote before but i couldnt find it anywhere...

ok im quite sure the original firmware for this drive was 13xx and i misflashed it... 1034 instead of 1334 :p

it is now 1034 and doesnt detect.

i dont know what default settings 1034 changes the drive to, but it wont boot with no HDD and i dont have a floppy drive.

i went to buy a floppy drive today and korea doesnt have any in stock and im gonna have to wait 2 weeks... so [*Profanity*] that if i have a choice.

im running XP and linux, and im trying to work out a way to boot into DOS with just a HDD. Toshiba BIOS doesnt seem to support booting from a USB flash drive or many other branded USB FD's.

I did manage to get the drive out and tried someones Standby - new HW scan trick but that didnt work...

any suggestions would be appreciated

Slim-to-IDE fixed it
I got my tiny little board in the mail today, and it flashed just fine.
I am so relieved.
I must say, Forums are the best way (and sometimes the only way) to get stuff fixed.

I flashed it with 1313b.hex - That the one with the region free code, eh?

Much thanks to all of you.
Merry Christmas

Yes. Slim2IDE is a sure thing... Emm. You need Patched 1313b or X313 to make the drive region free. Check with DISCInfo.

My DVD is still a little erronous when reading DVDs. I put in ICEAGE (a great movie - yay scrat) and it did NOT read it. It spun up, down, up, and finally stopped without being able to read the disc (physical problem). I ejected it and after six tries, it read it and I was watching the movie.

I'm pretty sure its dust wayyy down deep in the lens and mirror. I tried opening it up, but its too difficult to open the metal casing (the laser housing). I tried blowing in it really hard and it seems to be a temporary fix. Meh.. I can deal with it..

Tell me if you guys had this problem

-ElecEng

I have a DVD-ROM ( Toshiba SD-2502 ) on the laptop, it is fix drive, using firmware 1011.
I download upgrade for firmware 1011, then bootup from floppy disk into DOS mode, firmware also on the floppy disk, I just flash it from flopy disk in DOS mode.
When finished flash, I got message -- " Comparison error ". I also found " Erradr note ", it sard : address -- OBFFD, drive -- 20, file -- 00 "

So far, my laptop still can read this DVD-ROM, it still function ok.
At finally I found DVD-ROM did not flash, everything still same data.

Is any one know what it is happen at that flash ?
How to fix this problem ?

Ok, i misflashed the drive and all the stuff.. right now , i bought the adapter but my little problem is , removing the drive from the laptop, as the [*Profanity*] is small and weird is not a regular small phillips, and i dont know how to take it out, that [*Profanity*] is driving me crazy, is like star shaped, but it is TOO small, and i havent found anything to unscrew it with... if anyone knows the NAME of the scredriver i need, ill be grateful.. in venezuelan, and right now im visiting friends in the US, i would like to go to a hardware store (or whatever) and ask them for the [*Profanity*] without having to do a show to explain what it is im looking for..

thanks in advance. jr.

Sounds like it might be a TORX [*Profanity*] -- see here:

http://www.wihatools.com/267serie.htm

Thanks for the link... it looks like they got everything in there, i will check the site... in the meantime i will post a picture, is not only star shaped but the thing have a little bump in the middle that doesnt allow me to put a flathead [*Profanity*] in there... see ...




any help appreciated...

*EDIT* : i found this http://www.wihatools.com/701serie.htm that looks more like it.. now i need to determine the size, as there isnt any #4 listed on that site, and thats the reference i got... now that i have the name, i see what i can find...

Hi everyone, great discussions for the poor guys like me:) If you can also suggest me something it would be great.

For your info. I am posting my correspondance with the Toshiba Europe support centre. Might be useful. I saw a smilar posting before but this is sllightly different. and if you can suggest me any solutions it's much appreciated. As you see toshiba support gave up helping me.

I really don't want to try to hotswaping the drive coz I am afraid of burning my board.

I will try to find an IDE adaptor but I don't think it will solve my problem, as the DVD is not recognized any how...

The different problem is this: in most of the postings the board/bios recognizes the dvd as Slave or master. mine: nothing! check out the msgs below.

Anyways if you can help you will make me save 450US$. (Can you beleive they charge 450US to replace a SD-C2512 with a new one!!!!!!)

I tried as you said, extracting the files in to a bootable floppy disc,
taking out the hard drive, keeping the DVD, and restarting with the boot
floppy disc, and run teh command "update.bat". I received the same msg.

Just in case I tried this way also; by disconnecting the DVD, but no changes at
all.

while I do these computer still searches for the DVD.

Emre

Dear Mr Hepcanli,

thank you for contacting Toshiba Technical Support.

If you are disconnecting all drives, then update.bat for sure will see no
drive.
When I said disconnecting harddrive, that meant that DVD is still
connected in order to be flashed.

If you have any questions regarding this issue, please feel free to
contact me.

Thanks for your previous advice. I followed as instructed. I also removed
teh DVD, HDD and tried to do it again but evey time I tried to run the
"update.bat" I received this error msg:

<Primary>
0: (Master) Not Connect
1: (Slave) Not Connect

<Secondary>
2: (Master) Not Connect
3: (Slave) Not Connect

Thus, I couldn't flash it. Any other solutions would be much apreciated.

Here's an additional information you might be intersted. As I previously
said the CD rom wasn't working by any means i.e. DVD doesn't read the
recovery CD at start up, and the tray wouldn't open in windows. However
this
strange thing happened: By chance the system went to stand by, and when I
returned to windows DVD tray was working. if I open the tray and close, it
flashes couple of times, I think tries to read but nothing happens. It
still doesn't read anything. maybe this may help.

Looking forward your suggestions for a solution.

Regards

Emre Hepcanli

Dear Mr Hepcanli,

thank you for contacting Toshiba Technical Support.

Flashing of the firmware can be also done disconnecting harddrive, drive
now will be recognized, flashing, reconnecting harddrive.

Instructions:
Make Bootable Floppy Disk
Extract / copy all files in the ZIP file onto Boot Disk
Reboot PC with Boot Disk inserted.
For SCSI drives you MUST have an ASPI manager loaded in your CONFIG.SYS
(i.e. ASPI8DOS.SYS for Adaptec's AHA2940 SCSI card)
Type 'update.bat'
F/W will now be updated (you may be prompted to insert a disk, any CD will
do)
Wait for Flashing to finish.

Thank you for quick response. The details for the firmware are listed
below.

If you could also tell me how to install this firmware I would be glad.
Please note that the DVD-Rom is not currently working, and if there is a
method I would prefer without conecting my DVD-Rom drive to another
computer
as I don't have another laptop to connect the driver.

Looking forward for the instructions.

Best Regards

Well.. im happy to announce that after a few weeks triying to figure out how to extract the dvd-drive out of the laptop, i managed to do it yesterday succesfully... i needed to take two [*Profanity*] out from beneath the laptop keyboard... i did with no probs...

And today, just a few minutes ago, i managed to fix the drive...i used an old pentiumII-win98 IBM laptop wichh worked perfectly.. i just took the ibm cd-rom out, change the adapter to my toshiba dvd-rom slide it right in, load DOS-MODE , run the flashing software and success.. now the drive is back in place, and working perfectly.... ahh, and its also region-free ..

This forum has been very, very helpful, thanks to everyone who posted their problems and their solutions.

I tried to flash my toshiba dvd-rom sd-c2502 wich i have on my asus l8400 laptop and at some point it said comparing now. Anyway that was going on for hours and i just redooted the computer but then it said Primary Slame Master Failed and when a botted from the disket i used to flash the dvd it says that its not connected. It wont start on windows either. Is there a way to fix this. Please Reply. Thanks in advance.


And sorry for the bad english

hi i have a toshiba c2502 and i flashed it with the wrong firmware....i understand how to correct the problem and everything but i dont know where i can get a copy of 1313b.hex file so i can update it.

Thanks for the help in advance!

Hello..

Im in a really big trouble.

I have a Compaq Presario 1525Ea Notebook with a Toshiba SD-R2312.. and one of these days I've remembered to update the firmware... till here everything ok.

It happens that I didnt knew the version of the firmware and I made the R2312_X706 upgrade to the DVD/CD-RW... now Bios cant detect Cd-rom neither Windows...

I dont know the real version of the cdrom's firmware cause I didnt check it before I made the update, and I cant get the cdrom out of the notebook cause this notebook is terrible to open.

I went to Compaq to get this arranged but thy wanted 490

well... what i had a similar problem.. (as most people in this thread) , but i ended up taking out the cd-rom out of the laptop.. i spent quite an amount of time figuring out how to take it out, as is non-removable, i found out that is attached to the computer (laptop) chassis by two [*Profanity*] located beneath the laptop keyboard... that is on my TOSHIBA laptop... anyway, after i managed to take out the dvd-rom (different model than yours, same prob though) it was relatively easy,i used an old ibm laptop, took its cd-rom out, put the misflahed one in, the bios detected it with no problem, then i proceeded to flash it , u can boot from a floppy disk and run the flashing proggie... you can also get the "slim-cd to ide" adapter and put in any desktop computer and flash it from there, the adapter costs around 10us$ ...

really.. i was scared that i would have to pay lots of $$$ (or

you said you connected your toshiba cd rom to a IBM laptop. was that competable or it worked by chance?

Also when you tried to reflash your cdrom from your toshiba did you receive this following msg?

<Primary>
0: (Master) Not Connect
1: (Slave) Not Connect

<Secondary>
2: (Master) Not Connect
3: (Slave) Not Connect

The fist 2 lines bothers me a lot becuase it seems as if teh cdrom is dead.

any suggestions to that?

ok, i found out during all these little crisis, that all laptops slim cd-roms, and dvd-roms have the same connector in the end, and what usually changes from differents makes and models are NOT the connector BUT the adaptor they use, usually the fixed ones (like mine) inside didnt have any adaptor, BUT the one on the ibm sis have an adaptor (it was a *hot-swapable* model) that i removed from the original ibm-cdrom and just plug it in my toshiba dvd player , so i can hook it up to the ibm-laptop...

from a technical point of view it works like any desktop system, you can hook any cd-rom , or dvd-rom (or HD for that matter) to it, and normally the system detects it, no problem... my problem (and yours i see) came up because the toshiba bios is not flexible and after misflashing the drive the master/slave setting gets mixed up, and (i still dont understand exactly why) it doesnt detect the cd/dvd.... the compatibility is standar, maybe there are some exceptions, but the general rule is that it works no problem...

But in the ibm-laptop the bios detected the dvd with no problems, and it showed up in windows ( 98 ..) and worked no problem, even before i reflashed it with the correct BIOS...

About the message that was the one i got in the toshiba laptop while triying to reflash it, showing that the computer didnt detect the dvd-rom... it is not dead, is just the computer that doesnt wants to talk to it... that

Thanks I will try this. I hope it works.

I only have couple of questions on the method to do this.

1) You're suggesting that I insert my dvdrom to another laptop, the bios will detect the rom and I will be able to flash it properly. Is this risk free? I mean is there a possibility that mis-flashed dvdrom may corrupt the other laptop's bios?

2) As far as I guess I will do all these replacement works without the harddisk connected. I will open via bootable floppy. Is that right?

Thanks a lot. and if this works you will save me big time.
Emre

1) Yes, i am suggesting that... although,i do not take responsability for any damage, you do it at your own risk, i tell you, is like a desktop computer, just smaller... (i dont see limitations about what cd/dvd roms i can install on my desktop pc) , the bios is written in ROM, theorically is *not-corruptable* as it is not stored in hd, ram or anything but the motherboard itself... again, you do it at your own risk, it should work no prob.

2) the hard disk is optional, u need to have access to a DOS prompt (real DOS, not under windows) , and you may use a boot disk... in my particular case, i didnt have the floppy drive in the ibm laptop, but it has win98 installed, which allows me to run DOS , so i copied the files to the hard disk and run DOS , and did the flashing...

the other thing u can try is to get an adaptor...

http://www.directron.com/cddvdadapter.html this link was already posted in this thread... with one of those u can put the dvdrom in any desktop pc, and do the same reflashing procedure from there...

Hy,

when starting my Fujitsu-Siemens Lifebook there is the message:
Atapi CD-Rom: EOHIBA EVE-AOM AD C!4!2 !!!!!
(instead of Toshiba DVD-ROM SD-C2402).

After that, when starting SuSE Linux there is the error:
hdc:ToshybQ Tvt-Ro] SD=C24020 0 0 0 0 0 0 0, Atapi Unknown (type21) drive.

The DVD-ROM is not usable in Windows or in Linux. Could this be a Flash-Problem or something else? The DVD-ROM is a Toshiba DVD-ROM SD-C2402 ROM 1009.

The DVD-ROM is also sometimes not recognized from the BIOS (secondary master = no) and the next time it is.
Does anyone have a solution for this?

Hi, I upgraded my COMBO DVD/CD-RW drive Toshiba SD-R2412 with wrong firmware (1F16 version instead 1330) on my Toshiba Satellite A10 Notebook. There is IDE Error #1 massage now and drive isn't visible in the system (DOS or WIN_XP).
I decided to use first repair method with hard disc disconnecting. After this BIOS indicate two errors IDE Error #0 and IDE Error #1 and when I boot DOS using USB floppy it of course doesn

if you could have sent the photo of teh keyboard it would be easier.

Remove the long narrow pannel between teh keyboard and teh lid. use a flat [*Profanity*], or just a knife. remove the keyboard. there shoudl be 2 [*Profanity*]. Follow the (white rabbit) cd-rom and find where it ends. there shoudl be 2 [*Profanity*] holding the cdrom. unscrew them, a little push with the [*Profanity*] driver, or pull from the tray will remove. let us know the results.

Some info to you guys and your comments: I am really having hard times to find another laptop to flash my rom. finally some repairmen said that the controller chip was damaged and that's why it doesn't work. I am wondering how flashing the dvdrom in another computer will fix the damaged/corrupted controller chip?

anyways, if I can find a laptop or a ide adaptor I will try and let you know the results.

My combo drive isn't detected.....
Can my combo slave and sharing the ide with the FLOPPY drive?

Guys, my machine is getting crazier! Finally I flashed my dvd-rom. Plugged back in to my computer, restarted, and again the same IDE 1 error.

By chance my machine went stand by. when I turned on amazingly windows poped up: new toshiba dvd rom hardware found. !!!! what? and teh rom is perfectly working.

restarted the machine and it's not working again. I have to switch to standby and back again to make it work. I was wondering if I shoudl restore the windows in this status? I am just afraid to lose everything and now recover windows again.

I disconnected my HDD, tried to flash and again same msg: not connected.

Also do you think updating bios might solve this issue?

any idea is apreciated.

hi guys, I think I have tryed everything to recover the sd-c2502 with a wrong firmware versione flashed: at the end I keep getting the same message "*** UNKNOWN ROM TYPE !! ***".
Any suggestion?
Thanks

Well, can you help me?
My notebook is a Toshiba Satellite 2400-S251, with a (now dead) SD-R2102. Now I could get the correct firmware back but I cannot make the drive be seen.

When I turn on the laptop, I see "IDE Error #1" even when I unplug the DVD-ROM drive. Seeing the BIOS (by preesing ESC and then, F1), the IDE 0 info is not shown when I pull out the HD, but the IDE1 info is still locked on CD-ROM line.

Even that, I pull off HD and CD-ROM, and started DOS from floppy. After boot, I put on the CD-ROM and ran the UPDATE.BAT, but it still refusing to see the drive. Am I doing anything wrong?

Thank you for your help.
