I got it building, but it fails when talinkt to the drive.
It is probably caused bu sense field in struct scsireq:
it is SENSEBUFLEN long at maximum, whish is 48 bytes. Linux code
fills up to 128 bytes in the counterpart:
sg_io.mx_sb_len = sizeof(scsi_io->sensedata);
sg_io.sbp = scsi_io->sensedata;
With sensedata defined as: unsigned char sensedata
What does that mean? i woudl have expected to have buffer
lengths at the same size.
