Note: 
 
When the drive that is not conformed to ATA is connected to the disk drive above 
configuration, the operation is not guaranteed.

HA (host adaptor) consists of address decoder, driver, and receiver.  
ATA is an abbreviation of “AT attachment”.  The disk drive is 
conformed to the ATA-6/ATA-7 interface. 
At high-speed data transfer (PIO mode 4 or DMA mode 2 U-DMA 
mode 5), occurrence of ringing or crosstalk of the signal lines (AT 
bus) between the HA and the disk drive may be a great cause of the 
obstruction of system reliability.  Thus, it is necessary that the 
capacitance of the signal lines including the HA and cable does not 
exceed the ATA-6/ATA-7 standard, and the cable length between 
the HA and the disk drive should be as short as possible. 
No need to push the top cover of the disk drive.  If the over-power 
worked, the cover could be contacted with the spindle motor.  Thus, 
that could be made it the cause of failure.
