Operation of two hard disks 

 

The two hard disks are configured as follows in the factory state of the computer: 

 

Hard disk 0 

Hard disk 1 

Partition C: System, NTFS, 10 GB 
Partition D: Data, NTFS, remaining capacity 

Not configured 

You can use the two hard disks as a 2 HHD system. 

 

12.5.7.1  2 HDD system 

Depending on the device features, the Panel PC 877 can be equipped with two 2.5“ (PATA) 

hard disk drives. The slave hard disk drive is not set up. This gives you the option of backing 

up your data to this hard disk. The two hard disk drives are operated as master or slave on 

the primary IDE controller of the basic module. Please refer to your order documentation for 

the capacities of the hard disks. 

Booting from the slave hard disk 

The master drive is the default boot drive. However, you may also boot the system from the 

slave drive. 
In order to allow booting from the second hard disk drive, you need to set it up as primary 

boot device. Make the following settings in your BIOS Setup: 
Select Boot > Hard Drive > <Drive name> e.g. FUJITSU MHT2030AT- (PS), then press the 

"+" "-" key to move it up in the boot order. 
(PS) = Primary Slave, (PM) = Primary Master. 

 

 

Notice 
The drive letters for the partitions on both drives are assigned by the operating system used. 

You can change these in the Control Panel as required. 

 

A defective hard disk drive may block the IDE bus. To be able to continue working with the 

functional hard disk drive, disconnect the defective drive from the IDE bus and change the 

jumper settings on the drive as required (master setting, see the label on the drive.)
