Thanks for the reply Paul,
Both 3.5 inch drives are in Thermaltake A2396 external cases. One drive is
a WD 800gb green drive and the other is a WD 1T Green Drive. It seems that
most of the time whhen I tuen them both on at the same time after the
system is booted, one or both may not show in explorer. I have an
assortment of USB cables and have tried every one and seems to make no
difference. I have both of the connected to the usb/1394 combo header
plugged into the blue and red connectors. I also have another two port usb
header plugged into the other blue connector and when I try it I get the
same results. Should both be plugged into the same one or should I plug
one into each one, or does it matter?
I seem to remember that if both blue connecotrs are used at the same time
it can cause a problem with another device on the board but cannot recall
what the symptoms are as it's been a long time. BTW, I have tried
plugging both drives into the ports on the back of the board with same
results. Does the drive need to be powered up before booting if I want to
connect one to the esata port? Both enclosures have a swirch for
usb/esata. Any help would be appreciated, thank you.
In the picture of your product on Newegg, I see an AC adapter is provided.
And that is where the majority of power for the drive will be coming from.
The reviews in the "Feedback" column, note a few issues. Those issues
might be power related. One problem with a lot of electronics these
days, is cheap adapters. That's why reviewing the Feedback postings
is so important - to spot substandard components.
"Died after approximately 8 months of use. It appears to be a problem with
the power connector/power supply. The drive repeatedly spins up and down
when connected to the enclosure."
Perhaps viewing any LEDs on the unit, would give some indication of whether
it has a power problem (flickering, blinking, etc).
You can see the green Polyfuses, next to the blue 2x5 headers on the motherboard
(to the left of them in this picture).
The six black colored USB connectors in this picture, should have a Polyfuse
per two connectors. And those Polyfuses should be relatively near the stacks,
on the motherboard.
I see your 2x5 USB to slot adapter, in this picture. When you connect the
blue connector on this adapter, are you able to test each USB connector
individually ? Can you connect a USB flash stick and test each port, of
the two ports on the slot adapter ?
And once you pass that test, can you connect *two* USB flash sticks ? Are
both visible ? This would be a test case, of a device that cannot cause
any "power backfeed" type issues.
If you can pass that test, then perhaps the Thermaltake A2396 is pumping
power backwards, into the PC, via the USB bus power... That's about
all I can think of.
I've heard of cases, where you can only connect *one* of a product,
or there will be trouble. But I thought that was a particular NAS
box that did that. With USB, you'd think if each had a unique serial
number, or no serial number at all, you could connect multiple of them.
You might also consider using something like UVCView, or even Device Manager,
to see if both of them are present or not. UVCView would show you
whether the VID/PID config data is available to the computer or not.
If both of them reported exactly the same information, perhaps Windows
Plug and Play has a problem with it, and then the second one can't appear
in Device Manager. In which case, you'd want to use UVCView to verify.
UVCView and UVCView2 are Microsoft programs, which they've removed for
easy download. There are ways to get it - a recipe for getting the
latest one is here.
Basically, you'd be looking for proof, that the front end of each
ThermalTake adapter, can be seen. There would be two items, with the
same idVendor (VID) and idProduct (PID).
