Installing Hard Disk Controller Board
There are two types of HDU Controllers: the DTC (Data
Technology Corporation) and the WD (Western Digital). The
physical differences between the Controllers are:
1. The DTC Controller is a full-size modular circuit card. The
WD Controller is a half-size modular circuit card.
Each Controller formats the hard disk drives differently; therefore,
they cannot be interchanged without performing the following:
• Make a backup copy of all data if possible.
• Using the System Test, Low-Level Format the drive.
• Using the MS-DOS PDISK, partition the drive.
• Restore the backup data.
