SATA hard disk controller drivers are normally included with the Vista OS... Acer does not have any SATA drivers listed for this laptop:
They have a "FIR" driver posted but I have no clue what a "FIR" device is.
Open Device Manager, find and double-click the SATA device, click the Details tab, select "hardware id" and give me the hardware id string that begins with "PCI\VEN"
, (1st./top line of text only). If no driver has been installed for this device it may be listed under "Unknown Devices" or "Other Devices".
Example for my Intel/Dell Dimension 9100 board hardware id for this device is: PCI\VEN_8086&DEV_27DF&SUBSYS_01A71028&REV_01
