Try current BTS massstorage driver pack.
Or ask at BTS forum for iastor 7.8 support.

7.2 Use one of the following command examples to extract the
driver files from the different package types:
c:\iata_cd.exe -a -a -pc:\<path>
c:\iata_enu.exe -a -a -pc:\<path>
c:\setup.exe -a -pc:\<path>
When the command is run, the installation process begins;
simply click through the dialogs as prompted. This will not
install the driver, it will only extract the driver files to
<path>. After the extraction is completed, the driver
files can be found in <path>\Driver.
