[solved] cdrom/dvd drive not detected.

Hi

I just installed gentoo 64 bit on an older laptop that multiboots with linux mint. I find that my cdrom/dvd drive is not detected. Even though this drive works fine on linux mint.

It seems that it completely does not find your optical drive. It did seem to find your hard drive.

How is your optical drive connected to your laptop, is it USB or IDE or other method?

What brand/model laptop? lspci output could be helpful.

I would have to say this is a bit strange because being 64-bit it should be fairly recent and most machines' internal CD/DVD drives use the same controller as the primary hard drive... If it's an external USB drive then this would make more sense, would need to make sure you have all the USB drivers installed (including usb_storage).

Hi

The laptop is a Toshiba Equium A210-171

The cd/dvd drive is internal

The linux Mint system shows the drive as: TSSCORP-CDDVDW TS-L632H

OK, now, try the first part again, this time with 'lspci -k'.

Also it would be helpful to see how Mint does it... Take a look at the dmesg of mint and see what drivers were loaded before the optical disk was detected. lspci -k could be helpful there, too - to compare to.

lsscsi or looking at the tree in /sys could be helpful to see how it's connected...

Hi

I should perhaps point out that the xfce system giving this problem is a clone backup from another laptop on which the cd/dvd drive works perfectly. Whether this has any bearing on the problem I do not know. I understood that udev should find the new drive.

Readings from Mint

dmesg gives:

Perhaps a silly question, but does 'mount -t iso9660 /dev/sr0 /mnt/cdrom' work ?

mount -t iso9660 /dev/sr0 /mnt/cdrom gives special device /dev/sr0 does not exist

Sorry I failed to answer you earlier.

On the drive not detected system lspci -k gives:

Try CONFIG_PATA_ATIIXP = M or Y in your kernel config.

Or modprobe pata_atiixp if you already have the module built ... but recently I thought that Gentoo modprobed most needed modules automatically...
