I know it's been discussed but since it's been a while, has anyone
managed to get a second drive detected with this card?
I'm on Deb Squeeze with 2.6.32-5
sata_via is loading fine and I can see the drives if they're connected
individually but not if I connect both. If I do connect both I only see
one of them -which is always from the same port-.
To be clear, I'm not referring to the eSATA port. I'm not up to that
yet.

Hi All,
I tried setting both drives to 1.5Gbps on a whim and low and behold it
worked. btw. setting a single drive to 1.5 didn't help. I had to set
both.
I had considered this from the beginning but thought that since each
drive was detected on their own at 3Gbps there was no good reason they
couldn't both.
There must be something about that chip...Perhaps the way the firmware
allocates the bandwidth. ie 2 channels with a total of 3Gbps then a
second drive cannot coexists if the first requests all 3Gbps?!

I think VT6421(A) is 1.5 Gb/s only.
To be honest, It was never able to get it to work reliably, esp. with
Transcend and/or Kingston SSDs.

I'm confident you're right. I just haven't come across any doc outlining
that. Since I resolved this, the drives have been running stable no
issues at all.
