Hi everyone

I'm writing from Italy so pls sorry for eventual syntax errors!
I have a SCSI Toshiba CD ROM that is part of a professional machine (a
PC based machine) that cannot be replaced with any type of CDrom
because the eeprom of the cdrom (and of the machine) has been written
for a special type of work. OnThis cd rom drives usually flash slowly
when I insert a CD instead of stay off until something has to be read.
It seems to work with no problems but I remember that I read somewhere
that for Toshibas the slow flash of the unit's led means "fault" of
the drive.

Can anyone knows what exaclty means that slow flash so that I can
check for a specific solution?

Thanks for your help!

Bye
Antonio
 
If the CD-ROM drive is still functioning properly, there may be no need for
service.

To find out for sure, try to obtain information about your drive from Toshiba
themselves, either through their customer contacts of their website.

You'd only need to know if the slow flash indicates a problem.

But, again, if the drive is still reading discs and is working properly without
trouble, then the drive may not have a problem. - Reinhart
 
Hi Reinhart!

Thanks for your help.
I agree that the drive perhaps has no problems. But usually if I open and
close the tray make the led stop flashing. So I suspect something wrong.
I'm worried because this drive is used continuously during the operation of
the machine and if the drive stop working also for just one second the
entire machine stop working. This is why I would like to know more!

Thanks for your time!

Antonio

It takes time to spindle up CD when you close the tray. I suspect that
flashing is just idication of reading data from CD, which is not
possible until it achives required speed. I do have some Toshiba SCSI
drives at work, so I can investigate how they behave. Do you know
exact model of yours?

No, it flashes all the time. Sometimes, when I open and close more time, it
works perfectly without flashing. The manual that came with the unit (not
the manual of the cdrom) says that when this happens the cdroms have to be
replaced.

I will check the exact model of the cdrom, they are '97 model.

Thanks and bye!

The flashing of the LED is an indication of Data being red from the
Disc, it stops after the requestee info is read. If you have a drive
the is continuesly flashing its a good indecation of a read error from
the disc.

Could be the fault for the Disc itself of a dirty lens on the laser
assmbly. Have you tried a cleaner disc??

Mike.

The drive flashes also when it does not work!! It is a slow flash.

on..... off...... on....... off...... on........ off......

When the drive reads data it flash faster but withe the same slow flash "on
background", I don't know if it is clear!

I've already cleaned the lenses. The strange thing is that I blown dust from
the mechanism, I cleaned the lenses and the drive started working better.
When it flashes slowly a power cycle was enought to stop it. After 1 month I
can't stop that slow flash with several power cycle too.

I repeat: the drive seems to work correctly but since on the manual I read
that slow flashing means "fault" I would like to know what exactly is
faulty!

Thanks for your time!
