Hi all

I'm recording CD-R/W media with cdrecord using dev=<ide device> without problems but I tried to use readcd in order to read media in raw mode and doesn't work:

agapito:/home/ulisses# readcd dev=/dev/hdc f=/dev/null
Read  speed:  8450 kB/s (CD  48x, DVD  6x).
Write speed:  7056 kB/s (CD  40x, DVD  5x).
Capacity: 359819 Blocks = 719638 kBytes = 702 MBytes = 736 prMB
Sectorsize: 2048 Bytes
Copy from SCSI (0,0,0) disk to file '/dev/null'
end:    359819
readcd: Operation not permitted. Cannot send SCSI cmd via ioctl
agapito:/home/ulisses# readcd dev=/dev/hdc f=/dev/null

the error message comes from:

ioctl(3, 0x2285, 0xbffff570) = -1 ENOTTY (Inappropriate ioctl for device)

where the file descriptor is the IDE device

I would like to help if this is a kernel flaw

I was not sure were I should post this because Joerg Schilling doesn't support it's tools for IDE devices (not SCSI emulated) on Linux

Thanks all

Ulisses

PD: I had a crazy idea, there are a lot of Install Parties, why not "Bug hunting fests/sessions" before 2.6 reach the street?

Hi again,

I'm sorry I did not tell I was using 2.5.68 vanilla, also I just saw the new patches. I will report about it later
