SonicStage – SSAAD.EXE
Ssaad.exe and sscsisv.exe install with SonicStage. Ssaad.exe is the SonicStage Atrac Hard Disk Monitor and sscsisv.exe is the SonicStage Scsi I/F Server. SonicStage helps you manage your digital music content. You can use it to download music, create playlists, import/export audio and create custom CDs. More info can be found at http://www.vaio.net/sonyvaio659.html.
If you're not using a scsi drive, you can get by without sscsisv.exe. And users report having successfully removed ssaad.exe. By default, it puts itself in your Startup Programs. If removed, the next time you run SonicStage, it'll be back. So if you want to get rid of it, try using WinPatrol to disable it.
