Hard Disk Detection error

dupree · 07-06-2005, 06:11 AM

Hi, I am having trouble detecting my 2GB Fujitsu harddrive in Red Hat Linux 9.Kernel version is 2.4.20-8. When I run dmesg | grep hda I get :

Code:

[root@localhost root]# dmesg | grep hda
Kernel command line: initrd=initrd.img hda=ide-scsi root=/dev/hdc2 BOOT_IMAGE=vmlinuz
ide_setup: hda=ide-scsi
    ide0: BM-DMA at 0x2040-0x2047, BIOS settings: hda:DMA, hdb:pio
hda: FUJITSU MPC3043AT, ATA DISK drive

The Hard Drive shows up in the bios and in Redhat's startup where it enumerates it as hda but when I try fdisk -l I get:

Code:

[root@localhost root]# fdisk -l
 
Disk /dev/hdc: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
 
   Device Boot    Start       End    Blocks   Id  System
/dev/hdc1   *         1        13    104391   83  Linux
/dev/hdc2            14      9697  77786730   83  Linux
/dev/hdc3          9698      9729    257040   82  Linux swap

That is just my 80 GB drive which has Redhat installed on it. I want to partition and format the 2GB drive but can't since fdisk nor Redhat says it exists. Any ideas? Thanks.

Edit your /etc/grub.conf file and remove hda=ide-scsi then reboot.

I tried that but to no avail. Here is my new grub.conf file :

Code:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/hdc2
#          initrd /initrd-version.img
#boot=/dev/hdc
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-8)
	root (hd0,0)
	kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
	initrd /initrd-2.4.20-8.img

Thanks for the idea. What else could it be?

Does dmesg | grep hda still show hda=ide-scsi?

Code:

[root@localhost root]# dmesg | grep hda
Kernel command line: initrd=initrd.img hda=ide-scsi root=/dev/hdc2 BOOT_IMAGE=vmlinuz
ide_setup: hda=ide-scsi
    ide0: BM-DMA at 0x2040-0x2047, BIOS settings: hda:DMA, hdb:pio
hda: FUJITSU MPC3043AT, ATA DISK drive
You have new mail in /var/spool/mail/root

Yes. What do you think is the prob?

Did you reboot the PC? It might be that your system is not using /etc/grub.conf file.
The actual grub configuration is /boot/grub/menu.lst and Redhat links menu.lst to /etc/grub.conf. Check to make sure /boot/grub/menu.lst is the same.

dupree · 07-06-2005, 08:32 AM

Yeah I did restart. I checked and /boot/grub/menu.ls is the same as /etc/grub.conf.
Any ideas? Thanks

I do not know where else the command line kernel option can be coming from.
