Just wanted to thank everyone from this thread:
Finally got me new enclosure, set the switches for RAID 1, booted the
computer and it recognized the eSata drive.
Only question I have is why does the drive have to be on before the
It is my understanding, that only certain drivers support hot plug.
So the issue in this case, would be at the Jmicron level.
Vantec NexStar MX Dual Drive RAID0/1,JBOD
--- Jmicron JMB363 ---- PATA
---- SATA Internal (RAID1)
---- ESATA External ------- NexStar ----Drive0
SATA driver types are "IDE", "AHCI", or "RAID". Jmicron
may not support all of them. The latter two support
Hot Plug, which means the Jmicron can recognize a
powered drive, when the data cable is plugged to
the computer, after the computer is running.
So this would be a Jmicron issue, and really, what
good is ESATA without a working Hot Plug feature.
Hot Plugging is half the fun.
The Asus BIOS has entries -
Jmicron SATA/PATA Controller [Enabled]
Jmicron SATA Controller Mode [IDE, AHCI, RAID]
You can set AHCI, and that should allow Hot Plug to be
supported. What I cannot tell you, is whether Jmicron
separates their drivers into those three categories.
The older versions I have on disk, mention IDE and RAID.
OK, looking at the INF file, it looks like the RAID portion
covers AHCI and RAID.
If the NexStar is your boot device, then flipping modes
willy nilly in the BIOS, is not recommended. You may not
be able to boot if you do that. It is a lot easier to
experiment if the ESATA connection is for data storage.
If you were installing from scratch, and booting from
ESATA, then you'd use the Floppy32 or Floppy64 folders,
and place their contents on a floppy. Then, press F6
during install, and offer the RAID driver there, to cover
AHCI. Of course, having the OS on a Hot Plug interface,
doesn't make a lot of sense, because the OS will be
very very upset, if it is disconnected while the OS
is running. Virtual memory could be stored on that
disk, as well as a number of important, open files.
