I am looking for something that will allow my sparcstation 3.5" drive to read and write mac and PC diskettes. Someone told me that MTOOLS could do this. Is this true and where can I find it? Thanks, Mark (lever@vala.hw.stratus.com)

Someone told me that MTOOLS could >do this. Is this true and where can I find it? mtools supports DOS, not Mac disks. SunOS 4.1.1 has this feature builtin. DESCRIPTION PCFS is a filesystem type that allows users direct access to files on MS-DOS formatted disks from within the SunOS operating system. Once mounted, a PCFS filesystem provides standard SunOS file operations and semantics. That is, users can create, delete, read, write files on an MS-DOS formatted disk. They can also create/delete directories and list files in a directory. PCFS filesystems are mounted either with the command: mount -t pcfs device-special directory-name or mount /pcfs if the following line /dev/fd0 /pcfs pcfs rw,noauto 0 0 is in your /etc/fstab. File and directories created through PCFS have to comply with the MS-DOS file name convention, which is of the form filename[.ext], where filename consists of one through eight upper-case characters, while the optional ext consists of one through three upper-case characters. PCFS converts all the lower-case characters in a file name to upper-case, and chops off any extra characters in filename or ext. When displaying file names, PCFS only shows them in lower-case. One can use either the MS-DOS FORMAT command, or fdformat -d command in the SunOS system to format a diskette in MS-DOS format. -- Philip Robar Sun Microsystems Phone: (415) 336-1423 philr@eng.sun.com sun!knecht.eng!philr

Supporting Mac format has not been done often in the past. For the smaller formats (400K SS, 800K DS) the Mac uses variable speed motor control to allow varying the number of sectors per track. That is why PC's get 360K and 720K on the same disks. Without special hardware, this cannot be supported. The newer high density drives from Apple use the same fixed velocity layout as PC's, so you may see Mac layout support from mtools or a similar program in the future (but they still won't support the SS/DS formats). -- Cure the common code... | John Macdonald ...Ban Basic - Christine Linge | jmm@eci386
