IMPORTANT
HA (host adapter) consists of address decoder, driver, and receiver.
ATA is an abbreviation of "AT attachment". The disk drive is
conformed to the ATA-5 interface.
At high speed data transfer (PIO mode 3, mode 4, DMA mode 2, ultra
DMA mode 4 or ultra 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-3, ATA-4 and ATA-5 standard, and the
cable length between the HA and the disk drive should be as short as
possible.
