controller built in to the MB is Promise Fastrack 376. I am trying to
use eSATA to connect the SATA an port to an external SATA drive using
a NexStar3 enclosure with a USB/SATA bridge. The USB connection
However, when I try to use the SATA port nothing happens. Looking in
device manage for this device it indicates the device in working
properly. The driver date is 8/3/2002 with a version number of
126.96.36.199 by Promise Technology.
Since there will be only one external drive I do not want or need
Can someone help me to get this to work. if I need to supply you with
more info so you can help me please reply with what I need to give
With that chip, things might not be as easy. The second link contains
a reply I wrote a while back. It is not the fault of the chip as such,
but the provided driver and BIOS module. Chips like the Promise design
are usually "Software RAID", meaning the hardware is just some disk
controllers, without a fixed RAID function. The drivers enforce the
"RAID only" functionality. (With extra work, Promise could have provided
transparent drivers and BIOS option, if they wanted.) The third link
is probably the link I found the solution in.
So the deal is, you'd enter the FastTrack RAID BIOS and set the drive
up as a "single disk stripe". The RAID BIOS will write RAID array info
into a reserved sector on the disk. The metadata will say the disk is
a RAID0 containing only one disk.
This is all well and good if it was transparent. But the danger is, it
could affect the data which is already on the disk. If you wish to
continue the experiment, please back up the data on the ESATA enclosure
first. I cannot predict what the consequences will be with respect to
USB operation of the enclosure, or operation with other computers. The
reason I'm cautious, is I've had a problem with a Promise product before,
where the first partition "disappeared" when plugged to Promise. (It
"reappeared" when plugged to an ordinary controller.) So if
you want to set the disk up as a single disk stripe, and use the Asus
provided RAID driver, then at least make sure your data is safe
somewhere else, while you do the experiment. Once the Promise drive is
prepared as a single disk RAID, you can put the data back on the disk
if it got erased.
The USB is a lot safer and less work in this case.
Basically, I'm suggesting that you test for compatibility, if you want
to use the Promise chip, as well as the USB interface. Maybe if you
stick with ESATA to the Promise only, it wouldn't be an issue. But
personally, I'd want to make sure my enclosure was still "portable"
to other computers, after this experiment. And via both the USB and
