DeviceIoControl DFP_RECEICE_DRIVE_DATA (ID_CMD) on Win95/98

[Marcel Rasche]

Hello,

I use the DeviceIoControl to send the DFP_GET_VERSION and the
DFP_RECEICE_DRIVE_DATA (ID_CMD) command.
It works fine with WinNT, but on Win95/98 I have a problem.
I have read the Microsoft SMART IOCTL API Specification (1999) and he
write for Win95
"Under Windows95,the name of the executable is Smartvsd.vxd."

I have test with "vwin32" and with "smartvsd". But if call
DeviceIoControl with DFP_RECEICE_DRIVE_DATA (ID_CMD) than
return in the struct DRIVERSTATUS bDriverError=4 and bIDEStatus=0.
(ERROR 4 is INVALID BUFFER).

Thanks for help

Best regards
Marcel

>(ERROR 4 is INVALID BUFFER).

SMARTVSD requires the size of the output buffer to be

sizeof(SENDCMDOUTPARAMS) - 1

thanks for the information, but if set sizeof(SENDCMDOUTPARAMS) - 1 than
return also DRIVERSTATUS bDriverError=4.
