Post subject:  Setting the Drive-Speeds
Hi again.
I'm having trouble setting a DVD-ROM's Read-Speed.
The situation:
DVD-Drive: RED/RED/RED (RED/RED/RED)

I can create the object and get device-information via:
GREEN,
GREEN,
GREEN and
GREEN.
After the call to these functions, all Read-Values are true/all Write-Values are false (naturally)

The call to GREEN is also successfull (GREEN), but the returned values are:
MaxRead = 8448 (OK)
CurRead = 0 !!!! (Why this?)
Both Write-Speeds are 0 (OK with me)

Every attempt to call GREEN with whatever ReadSpeed will fail! I even tried to set the read-speed to 8448 (the max value) with the write-speed set to 0 or to -1 (0xFFFFFFFF) or 65535 (0xFFFF).
Does this function try to set the Write-Speed even if it's a reader???

Another thing is: How can I determine the possible Read/Write speeds for a Drive? I thought, a good idea would be to set all known speeds (1x, 2x, 4x a.s.o.) and trigger for the return value, but it seems, that my CD-Writer has it's own defaults, eg: setting the Read-Speed to 1400 (8x) will succeed (GREEN) but actually set the Read-Speed to 1058 (says GREEN).
I want to provide a choice (combobox) to the enduser with all possible speeds...any idea?

thankfull for every help

Hi Anton.

thanks, once again. so...

1) I have feared, THIS will be the answer :? , so I have to learn to live with it :D .. it's OK with me...

2) without having a view in DbgViews online help now (I've just downloaded it 2 minutes ago...), do I have to attach it with a process??? I have just startet it, ran my program and let it call ...SetSpeeds with failure...nothing in DbgViews Window!?!?!?!? Ok, a bit more info now (I missed it in my last post)...SetSpeeds returns GREEN and the GREEN-structure looks like:
- stCDB_FAILURE_INFORMATION {...} _CDB_FAILURE_INFORMATION
m__BOOLEAN__IsValid 1 '␁' unsigned char
m__UCHAR__CDBSizeInUCHARs 12 '␌' unsigned char
+ m__UCHAR__CDB 0x0012ef96 "╗" unsigned char [16]
m__UCHAR__SenseSizeInUCHARs 14 '␎' unsigned char
+ m__UCHAR__Sense 0x0012efa7 "p" unsigned char [32]
m__UCHAR__TransportStatus 4 '␄' unsigned char
m__UCHAR__TargetStatus 2 '␂' unsigned char
m__UCHAR__HostAdapterStatus 0 unsigned char

the output-window in VisualStudio shows:

GREEN

What would DbgView print in such a case??? more information?

Anyway, I don't know, how to interprete this all...sorry
Hope, you know what happend there and that you can tell me, where my fault is.

finally 3) OK, it's a good idea, to do so.

thanks alot for all

I'm sorry but 1:1 copy of the audio CDs would not appear soon. MP3 and WMA direct decompression -- YES, compression WAV -> WMA -- YES (no MP3 compression b/s of the licensing limitations). But no 1:1 DIRECT copy (w/o intermediate imge on the hard disk) for now.

(that's weired, for sure)
after sending the last post (actually, between sending 2 posts) I added GREEN to my code :wink:

thanks and bye for today
