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
At high speed data transfer (PIO mode 3, mode 4, DMA mode 2 or ultra DMA mode 2), 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
