Toshiba Satellite R10 ユーザーズマニュアル

When an error occurs in the hard disk test, the following message is displayed: 

HDC status = XXXXXXXX 

Detailed information about the hard disk test error is displayed on the screen by an eight-digit 
number. The first four digits represent the hard disk controller (HDC) error status number and the 
last four digits are not used. 

The hard disk controller error status is composed of two bytes; the first byte displays the contents 
of the HDC status register in hexadecimal form and the second byte displays the HDC error 
register. 

The contents of the HDC status register and error register are listed in Tables 3-3 and 3-4.
