how to tell if a ide cable is ultra dma & is it realy needed for a 133 mhz drive?

[dsads]

How many old ide cables. though they would work fine with my maxtor 80
gb 133 mhz drive in the ultra dma 133 mhz mode. but its not so. Only
reach speeds of 27000kB/s. Is the ultra dma 133 mhz ide cable
necessary for usage of this mode & getting full 51000 kB/s advertised
by the manufacturer!?!

please advise

Yes, you need to use the correct rated cable.

Above ATA33, you need an 80 conductor cable. A conductor on that
cable tells the drive that it's the correct cable.

All 80 conductor cables made to the ATA spec, will work from ATA33 up
to ATA133. Some drives must be set to the higher mode. ATA133 is mostly
advertizing "hype", since no present drives can generate data that fast.

Of course, your MB or controller card must support the higher mode.

80 wires = Ultra
40 wires = less than Ultra

See my previous reply to you.

Your use of the ATA33 cable will dramatically lower your scores, but
don't expect to get 51000 KB/s in Sandra... that's closer to 10K RPM
SCSI territory.
