I am running Vista Home Premium. I had been running 2 Western Digital
500GB drives in RAID 0 mode. The external enclosure was a Fantom
enclosure.
The controller was going bad, so I bought a Xtrastor 3.5 x2 HDD
enclosure which supports RAID 1.
Anyhow, when I hook it up via USB, it only detects an 8GB drive. Once
I got it to detect it as a 75GB drive. If I hook it up as an eSATA,
Vista does not see it at all......
It should detect close to 500GB since the other 500GB is for the RAID
1.
I have a PB5 motherboard. I have tried a lot of things via the cables
and re-booting and such, no luck. Anyone have any suggestions?
Thanks!!!

involved in recognizing the size of the drive. And your OS will see
whatever the external enclosure sees, so you'd have the same problem
with XP or linux, for that matter. This is a hardware (or firmware)
problem with the external enclosure. -Dave - Hide quoted text -

Dave,
Are you saying the enclosure is bad? Or defective? Or is there
something else I am missing or not doing?
John.
Could you try connecting the hard drive, directly to your motherboard ?
That may make it easier to verify the drive is functional. The
P5B motherboard should have some SATA ports on it.
In terms of drive size, a drive can be artificially "clipped" in
size, by means of HPA (host protected area). I'm not saying that
is what has happened to your drive, but it is a theoretical
possibility. (Since the drive has reported two different sizes,
then this likely isn't the problem.)
http://en.wikipedia.org/wiki/Host_Protected_Area
The ESATA port on the P5B, connects to a Jmicron JMB363. You may
need to configure the BIOS for it to work, and as I don't know
anything about Vista and driver detection, maybe a driver is needed
that isn't there. I'd try a non-RAID setting on the Jmicron
in the BIOS, for example.
It is possible the drive enclosure doesn't have enough DC power,
in which case you could try connecting just one hard drive
and see if that works and is detected. During spinup, some
drives draw 2.5 amps from the 12V rail.

Hi Paul,
I know the drives work. If I hook them to the old enclosure the
detect at 1TB.....but I want RAID1 so I bought the new enclosure and
it only picks up 8GB, and in the drive manager there is a small 'x' on
the drive description.......
John
Did you format the raid1 partition after setting it up?
