Master or Slave?

vbimport

#1

I have a CD Writer... And a CD Reader so as not to kill my writer too soon (since readers are not expensive at all nowadays).

the question is, my reader is of higher reading speeds than my writer...

Which Drive should I put as master, and which one as slave ?


#2

as discussed many times before, the preferred position for your writer is secondary master.


#3

i put the writer on every possible position…accept primary master. Never had problems.

but that depends on lot of factors…

to be sure use the secondary master…as mentioned above


#4

Secondary master ?

Means it should be on IDE 1 set as MASTER and the reader on IDE 1 set as slave ?

And hard disks set on IDE 0 one master and one IDE 0 slave.

is that right ?

Yep.

If you do a lot of on-the-fly copying i suggest setting your cd reader on a different ide bus than the cd writer.

In that case it would be

IDE 0 : Master : Harddisk
IDE 0 : Slave : CD Reader

IDE 1 : Master : CD Writer
IDE 0 : Slave : Nothing

Mind you that the ide bus will adapt to the maximum speed of the slowest ide device. So if your IDE is standard UDMA133 and you have connected an UDMA100 harddisk and an UDMA33 cd reader… all things go back to UDMA33. This is crappy for your harddisk.
If you want performance then i’d suggest :

IDE 0 : Master : Harddisk
IDE 0 : Slave : Nothing

IDE 1 : Master : CD Writer
IDE 1 : Slave : Cd Reader

In that case the harddisk will always perform at its peak performance. If in this case the CD Reader is UDMA33 and the CD Writer is UDMA 66 , the IDE bus speed will be UDMA33 , but this is still enough for the writer (UDMA33 is 33 Megs per second… never seen a writer do that).

If you have an additional on-board IDE controller (Promise thingy) i suggest putting all things on master :

IDE 0 : Master : Harddisk
IDE 0 : Slave : Nothing

IDE 1 : Master : Cd Writer
IDE 1 : Slave : Nothing

IDE 2 : Master : Cd Player
IDE 2 : Slave : Nothing

IDE 3 : Master : Nothing
IDE 3 : Slave : Nothing

In that case all the IDE Devices will perform at top performance.

Well thanks :slight_smile: , but keep in mind i don’t have every knowledge and the others who contributed rule as well :slight_smile:

I was thinkig of writing some ide/scsi/settings thingie document sometimes.

I heard from another guy that the limiting bandwith is the master drive…

which means if you have a 66 UDMA on IDE 1 MASTER and 33 UDMA on IDE 1 SLAVE…

then the 66 will run at 66 and the 33 at 33…

BUT

if you have UDMA 33 as master and udma 66 as slave, boith will run as 33…

what do you think of that ? true or false ?

I seriously doubt that the controller chip would switch constantly back and forth from 33 to 66 to 33 to 66 , and so on.

So i think both will run at 33.
