I cant find my fourth drive, supposly it should be hdd1, or?

It should be hdd something if its partitioned.

Does the motherboard BIOS recognize the drive during POST?

Is the drive enabled in the motherboard BIOS and the parameters set to auto?

Did you check the power connector and IDE cable on the drive to verify that they are plugged in correctly?

Yes, the drive is recognized in BIOS, and the parameters is set to auto.

Check the output of dmesg to check for any messages / errors related to hdd.

Did you have a cdwriter or cdrom attached to hdd at one time? If so SCSI emulation might be setup for hdd. Edit your bootloader to remove the hdd=ide-scsi.

affeee 09-23-2003 07:57 AM
Yes i had previosly a cdwriter attached on same ide-channel.
This is my grub.conf:

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that

#boot=/dev/hda
default 0
timeout 2
splashimage=(hd0,0)/grub/splash.xpm.gz

root (hd0,0)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdd=ide-scsi
initrd /initrd-2.4.18-14.img
shall i remove the hole line

or just
Quote:
hdd=ide-scsi

michaelk 09-23-2003 10:07 AM
Just the "hdd=ide-scsi" part.

Once the configure file has been edited reboot the computer for the change to take effect. You should now be able to see the hard drive.

Thank you very much... now i can see it.
