I have been trying to install a eSata PCIe card into my machine (Gigabyte
GA-P45-DS3 MB) to drive my Seagate FreeAgent external HDD. So far I have
tried two cards, one with a SIL3112 chipset and the other with a JMicron360
chipset. Both cards appear to install and drivers loaded (x64 drivers).
Device Manager indicates the cards are functional. The problem is the
Seagate FreeAgent drive is not recognized. The drive functions without
problems from a USB port. Although not relevant I have four internal HDDs
connected to SATA ports.
Scanning Google gives rise to many comments on the problem of getting PCIe
eSATA cards to function correctly but to date I have not seen a definitive
answer as to how to get the card to function. There is an indication that
AHCI needs to be loaded and I have tried this. It seems that AHCI drivers
can be loaded after the OS by changing the value in the Registry of msachi
(HKLM\system\CurrentControlSet\Services\Msachi) to 0, then to reboot and
enable ACHI in the Bios. When I did this (Msachi was already at 0, which
seemed strange as the indication was that it should have been at 1), WIN 7
x64 stalled during reboot. As an aside it took several minutes to get past
loading the ACHI drivers which seemed wrong. I have reverted to running the
drive from USB.
That's the story to date. Has anyone any experience of successfully
installing aPCIe eSATA card and can give some guidance to the procedure?
