I'm not sure what you mean here. IOCTL_DISK_GET_LENGTH_INFO doesn't return sectors -- it returns bytes, and it returns them as a 64-bit integer. That will hold almost 2 exabytes, about a million times larger than any hard disks that exist today. If you follow that sequence with print struct.unpack('Q',buf)[0] you should see the length in bytes. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
