esata port
I have a Dell Studio 15 model 1555 Windows 7 Home 64bit that came with a Esata port. I have a Thermaltake BlacX Duet that holds 2 sata HDs. I connected this unit with 2 HDs installed. The computer recognized the HD in slot 1 but did not recognize HD in slot 2. It does recognize both HDs if I use the optional USB port on the Thermaltake BlacX Duet. Please help with fixing this problem.
this setup works perfectly on my XP Pro desktop, so I would think the hardware in not the problem.
I installed the most recent Dell bios and Intel chipset driver for this model.

From the Thermaltake BlacX Duet website.
When utilizing eSATA interface, Port Multiplier feature is required on the host system’s eSATA
controller for two hard disk drives to be seen at the same time. All USB supports Port Multiplier function.
A Silicon Image SiI3726 Chip, supports FIS-based and command-based switching SATA host controllers.
A Serial ATA port multiplier is a device that allows one to connect multiple
SATA devices to a single SATA host port in a similar manner to that of a USB hub.
Many common controllers do not support this feature
, as it is not a requirement for a SATA controller.
