Re: IDE CD problems in 2.6.13rc6

I just remember a path I took when resolving the issue further to my post
below.

Here is what man hdparm says on -i and -I:

-i Display the identification info that was obtained from the
drive at boot time,
if available. This is a feature of modern IDE drives, and may
not be supported
by older devices. The data returned may or may not be
current, depending on
activity since booting the system. However, the current
multiple sector mode
count is always shown. For a more detailed interpretation of
the identification
info, refer to AT Attachment Interface for Disk Drives (ANSI ASC
X3T9.2 working
draft, revision 4a, April 19/93).

-I Request identification info directly from the drive, which is
displayed in a new
expanded format with considerably more detail than with the
older -i flag.
There is a special "no seatbelts" variation on this option,
-Istdin which cannot
be combined with any other options, and which accepts a drive
identification
block as standard input instead of using a /dev/hd*
parameter. The format of
this block must be exactly the same as that found in
the /proc/ide/*/hd*/iden­
tify "files". This variation is designed for use with
"libraries" of drive
identification information, and can also be used on ATAPI drives
which may give
media errors with the standard mechanism.

Note the last sentence:

' This variation is designed for use with "libraries" of drive
identification information, and can also be used on ATAPI drives which may
give media errors with the standard mechanism.

Hi all,

Maybe teaching you all to suck eggs here, but I used to get this a lot on my
CD's - KDE ran some probe and as the CD[s] where empty logs filled up rapidly
with that error. I thought the[a] drive was duff, so bought a new CD-RW.

Made no difference :-/ I then investigated further, and read that instead of
the SCSI emulation, it was superceded by IDE-CD.

kernel 2.6.12.3

Kernel command line: BOOT_IMAGE=Nicks ro root=303 hdc=ide-cd hdd=ide-cd

Fixed the issue for me. But as I say, teaching to suck eggs, but I thought I
would mention it.
