Thank you for your reply, even if currently not that interesting for me because after the first CD writer for IDE were available I stopped to use SCSI and didn't come back to it since then.
Does the Python open() command not work the same way for SCSI drives as for IDE or USB drives (I can't try it myself, because of above)? Claudio P.S. for those who are interested I have uploaded a Python script I wrote for myself to have a reference to this subject to: http://people.freenet.de/AiTI-IT/Python/HowTo_AccessRawSectorsOfPhysicalDrives.py :-) "sam" <[EMAIL PROTECTED]> schrieb im Newsbeitrag news:[EMAIL PROTECTED] > The following site contains my routines to access information from the > Microsoft SCSIPASSTHROUGH layer under windows.
