The ide disk use the block device /dev/hdX, and is very strange that
your disk is recognized same a scsi device.
Usb,sata,sas,scsi use the sdX block system
The first step is to understand what type of hd device your system
recognize, and the raid array configuration
If you have the FC7 installed, go under the /proc/scsi and /proc/ide dir
and see what hw the system use.
Is a example for my sata system :
-r--r--r-- 1 root root 0 14 giu 09:36 device_info
-r--r--r-- 1 root root 0 14 giu 09:36 scsi
dr-xr-xr-x 2 root root 0 14 giu 09:36 sg
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: MAXTOR STM332082 Rev: 3.AA
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: Optiarc Model: DVD RW AD-7170S Rev: 1.00
Type: CD-ROM ANSI SCSI revision: 05
In every cases, its important the raid hw and the configuration of the array
When i asked if your system use a raid controller embedded with the
mainboard, was because many hw producers use a software raid intestead
directly into the bios.
This is a false raid controller and linux dont discovery the bios array
but the disk directly.
Use a lspci command to see what pci hw the system use, and if you want
more information use the -v flags
I think that a visual inspection of your system is a nice idea to
understand the hw configuration.
