Tronman,
To answer you question try doing the following:
It is possible that the ASPI drivers that we are using may not correctly support that Yamaha 8424 drive.
Download and update the ASPI drivers from:
http://www.mtu.com/vbulletin/showthr...p?threadid=493
NOTE: This only pertains to Microstudio 2.314.
Once you have downloaded and installed these files do the following:
1) Open Microstudio
2) Go to the
Drives Menu
3) Select {b]ASPI Drivers...[/b]
4) Change this selection from "Use the MTU installed driver" to
"Use the default driver"
5) Close Microstudio and reopen it for this to take affect.
