whats the point in ide-scsi emulation ?

qwijibow · 05-31-2003, 05:24 PM

for whatever reason, when i installed linux, redhat 9 it decided to pass a value to the kernel at bootup so that my cdrom drive would be treated as a scsi drive, even though its an ide disk.

in other words, it should be accessed through

/dev/scd0

instead of

/dev/hdc

it worked fine, but cdparanoi didnt work, so i couldnt rip cd's

after removing the kernel thing so my ide drive is actually treated as an ide drive, everything works exactly the same as before except i can now rip cd's

so question 1 )what is scsi
question2 ) why did linux decided to emulate an scsi drive ???

whatt the point ?

the emulation is so that you can burn. you have to have the emulation to burn, unless it's been changed very recently. that's why it does it.

if you want a program to rip, take a look at grip. plays cds and rips them into the format of choice.

cheers.

grip uses cdparanoia to rip.
it does not have the ability to rip itself.

also, the drive im talking about is a dvd player, NOT a cd writer.

which is strange cos i have a cd writer, and it did not do a scsi emulation on that drive.

(but i dont care since linux dies every time i try to mount that drive)

some systems just like setting things as scsi emulated if you have a burner as it makes copying them much easier, many cdrecord front ends can only read from scsi drives as well as burning to them.

true IDE burning should be implemented in the 2.6 kernel branch i believe, but xcdroast claims to be able to do it already anyway.

I'd guess that emetib is more than aware that grip is a front end only... he was just trying to help you.

Ok, thanX guys.

if i can just get linux to stop crashing when i mount scd1 (my cd re writer in secondary slave) my linux box will be doing everything my windows did....

ive tried almost everything, and in desperation, im on redhat network now odwnloading all upgrades, especially the kernel,just incase....

In order for it to play DVDs, it will have to emulate scsi.

Of course, you can load/unload the module at will. I would make different mount directories for ide and scsi emulation to keep myself from getting confused.

not at all true i'm afraid. everything works fine with IDE.
