The Question is: How do I mount the floppy drive on an ES-40 Alpha Server? Once mounted, how do I read a binary file from a 3.5 inch high density diskette? I have Compaq's Pathworks32 ver7.2 but can't find the "PCDISK" utility mentioned in another FAQ. Also, how do I mount a 4mm tape drive and read binary files from it to the ES-40 disks? The Answer is : OpenVMS uses the MOUNT command to prepare OpenVMS to read and to write native ODS-2 and ODS-5 disk storage media volumes, followed by commands such as DIRECTORY and COPY and such. Foreign-format volumes will use the MOUNT/FOREIGN command. This makes the volume accessable to file structure tools that might be able to manipulate the contents of these foreign volumes. OpenVMS uses the EXCHANGE utility for its various recognized foreign volume formats. Microsoft FAT-format volume structures are not presently supported by any tools that are available within or provided within the OpenVMS operating system distribution kit. For information on Microsoft FAT-format media, please see topics (4), (3476), (4120), (7910), and others -- most of these topics will reference a section of the OpenVMS FAQ currently entitled "How do I access a Microsoft Windows floppy disk from OpenVMS?". PATHWORKS32 is the Microsoft Windows client package, the PCDISK tool referenced is an undocumented component of the HP Advanced Server (formerly known as PATHWORKS server) package. Mounting a tape is analogous to mounting a disk, and also uses the MOUNT command. Like the Microsoft FAT format volume structure, it is the structure of the data on the volume that is of more central interest. Many tapes use ANSI volume structures and OpenVMS can read these directly using tools such as DIRECTORY and COPY. Tapes which use other structures will require use of tools such as an application program using language-level I/O calls or using calls to the OpenVMS $qio[w] and $io_perform[w] I/O interfaces. For information on volumes and device access, please see the OpenVMS I/O User's Reference manual and the Guide to OpenVMS File Applications manual. For details of the language I/O interface(s), please see the language user documentation for the particular programming language(s) involved.
