In the Disk Management tool (for instance right click "My Computer" -> "Manage" to get there via the "Computer Management" admin tool) disks are numbered "Disk 0", "Disk 1", etc. This order corresponds with /dev/sda, /dev/sdb, etc. Partitions are numbered left to right. /dev/sda1 corresponds to the first partition, etc. Similar for CD-ROM and DVD drives. In the Disk Management tool they are numbered "CD-ROM 0", "CD-ROM 1", etc, which corresponds to /dev/sr0, /dev/sr1, etc.. Alternatively to /dev/scd0, /dev/scd1, etc. For tape drives, have a look into the Device Manager. The properties dialog of each tape drive has a tab "Tape Symbolic Name". Tape0 corresponds to /dev/st0, /dev/nst0, Tape1 to /dev/st1, /dev/nst1, etc. Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Project Co-Leader cygwin AT cygwin DOT com Red Hat -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
