Re: XP boot error with SATA and ATA hard drives

Yes, you are correct in that the POWERPLAT1 device I mentioned
contains a "normal" SATA data connector and not an eSATA
connector. Like all these similar devices, as you know, it still can
be used effectively as the "bridge" to an external SATA HD and
facilitate a direct SATA-to-SATA connection between the SATA
HD and the computer. Presumably there is an advantage to an
eSATA connector in that it's a more secure connection and (according to
specifications) a shielded data cable is to be used
for the connection.

Yes, and those shielded eSATA cables aren't cheap:

Based on our experience to date with this device and similar ones,
we really haven't encountered any signal-type problems that we could
attribute to using a standard SATA data cable as opposed to using
a shielded SATA data cable with eSATA connectors.


The shielding is for keeping the EMI (electromagnetic interference)
IN as well as keeping it OUT. With the SATA specs pushing up the
clock rate and doubling the maximum length of the cable and leading
outside the PC's case, interference TO other equipment as well as
interference FROM other equipment is taken into account.



The advantage of the POWERPLAT1 device is, in our view, as I previously
mentioned, i.e., it contains a power connector.

What kind of cable do you use externally for the power?

*TimDaniels*


We've used two basic types...
1. We've had custom-made power cables made up for us that have the 15-pin
SATA power connectors on each end. Custom-made because we were unable to
find this type of cable readily available. (I don't know the source of this
type of cable).
2. The ordinary SATA power cable having a 15-pin SATA connector on one end
and a Molex plug on the other end. In many instances we connect a
Molex-to-15-pin SATA connector adapter to the Molex end.

I have to add that with more & more external SATA enclosures coming onto the
market - many of which are combo units providing both direct SATA-to-SATA
capability as well as USB connectivity - and with these units providing an
auxiliary power supply - it's probably more practical for the average user
to use that type of device to house his/her external SATA HD.
