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 :

ll /proc/scsi/
totale 0
-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

 cat /proc/scsi/scsi
Attached devices:
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.

Bye.
