Hi

I have a portable raid drive with dual interface eSATA/USB.

(BT-3058 Raidecker http://www.ultimateftp.co.uk/pdf/RAIDeck.pdf)

Ive always used it via USB satisfactorily for a couple of years however
this week I tried the eSATA connection for the first time (hoping to
benefit from the higher speed).

However it didn't autoplay or automatically open a window.

On going into drive management (in Windows 7) it was showing up as an
unformatted drive (Eeeek!!).

I counted to 10 and abated a panic (thinking I may have lost 100GB+ of
data).

On reconnecting it via USB - there was my data. Phew!

Does anyone know why using the eSATA would cause this?

Hope someone can enlighten me.

Cheers

Ian

What, no backup? Repeate afte me: "RAID is not backup.
It does not protect against user error."

No idea. Looks like a design error. However the lesson should
be to not experiment with life data that you (apparently) do
not have a backup of.

Is your motherboard eSATA controller set up in JBOD
mode to match the external drive? With USB the controller
in the external will take care of interfacing, but with eSATA
the MB controller has to match with the external drive.
There's also the matter of whether your MB eSATA is set
as IDE or AHCI. The setting RAID, JBOD, IDE, or AHCI
at the host end is controlled by the MB eSATA drivers.
