Hi Jeff,

I have upgraded from 2.6.3 to 2.6.5-rc3 and can't see the secondary
sata drive anymore...

I am seeing this:
libata version 1.02 loaded.
sata_via version 0.20
sata_via(0000:00:0f.0): routed to hard irq line 11
ata1: SATA max UDMA/133 cmd 0xC400 ctl 0xC802 bmdma 0xD400 irq 20
ata2: SATA max UDMA/133 cmd 0xCC00 ctl 0xD002 bmdma 0xD408 irq 20

scsi0 : sata_via
ata2: no device found (phy stat 00000000)
ata2: thread exiting
scsi1 : sata_via

oh, and are both disks SATA?

Or is the 37G drive a PATA drive on a PATA->SATA adapter (a.k.a. bridge)?

Vendor: ATA Model: WDC WD360GD-00FN Rev: 1.00
Type: Direct-Access ANSI SCSI revision: 05

WD Raptor electronics includes PATA->SATA bridge.

Yes, a lot of drives do.

I meant outside the drive, an adapter/bridge the user plugs into the
device, that allows it to pretend it is a SATA device.

Is there any difference (except cabling and power) ?

Most drives use the well-known Marvell phy chip, while adapters are a bit more random...
