The product is actually TSSTcorp CDDVDW SH-S223C F/W SB01 and
not SH-S223B as per dropdown list.
Downloaded latest Firmware file SH-S223C_SB04.exe and ran it from the desktop.
My OS is Windows7 Ultimate 64 bit.
This exe file starts up TSDNwin.exe which “freezes” the computer.
Have to use Task Manager to End Task.
It hangs at the flashing “Caution” message that comes up.
Tried running TSDNWIN.exe from the Desktop but
this needs bin files which Samsung site does not seem to supply.
Any help to solve this would be appreciated.
