Re: weird cdrom problem

Problem solved.

I installed an older version of linux, Redhat 7.2; and used lilo
instead of grub as the boot loader. A boot parameter of lilo

hdd=ide-scsi

made the cd drive visible to both windows and linux.




OK, it may help you to know some of the history on that. The author of cdrecord, understandably, wrote it for SCSI devices for various technical reasons. But most CD drives are IDE, so some smart aleck wrote a kernel module to provide a SCSI like interface. This is not necessary at all for normal reading, only noormal writing, at least from my reading of that old widget. The drive would show up as both IDE and SCSI when doing this.

But he wrote, or included, what are basically *BAD DIRECTIONS* to do it. This does not need to be, and should not be, in the LILO, or boot loader, it can be manually or automatically loaded after boot time, much as network drivers can be so loaded. This prevents all sorts of interesting conflicts.

More contemporary versoins of the Linux kernel have built-in drivers to handle IDE, ATA, or PATA drives correctly, and the latest published versions of RedHat all have updated versions of cdrecord and DVD writing tools which support writing to IDE or PATA devices.

(Note: SATA drives look like SCSI to Linux users.)
