Has anyone on the network run any WORM media with ISC 2.0.2 ???? I am looking for a LARGE removable capacity and I think this will be a good thing to look at ... what are my compatibility issues ???* I assume these type of drives are available with scsci interfaces on them ... does Unix need to know anything else about them ????? ========[ Xanadu Enterprises Inc.

The MB I machine runs SYSV.3r2.1 from Intel and the AT runs 2.0.2 from ISC. Both machines also have Maxtor 8760S SCSI harddisks (760Mbyte). I'm using device drivers from Sysnet, Inc. 125 Blueberry Dr. Scott's Valley, CA (408) 438-5120. Their software provides raw I/O and also partitioning service- so the WORM disk doesn't have to be used as a single huge device. I've had some problems: On the MB1 machine I can't copy from the SCSI harddisk to/from the SCSI WORM (except using dd) but everything works OK from the ST-506 disk to/from the SCSI WORM. Sysnet has the same problem using a Maxtor WORM but not using a Panasonic WORM. On the AT, booting with the WORM software installed seems to hang the Maxtor hard disk. The WORM software for the ISC system works through the ISC device driver, doesn't replace it. The only harddisk the AT has is the SCSI Maxtor. We're still working on this-stay tuned. Software considerations: The WORM software allows mounting a worm partition as a filesystem but, since the hardware is WORM, the whole filesystem is unalterable. You have to make the filesystem up in its final form and write it out. Bottom line: It's available but there are some hardware combinations which don't work well. LeRoy M.
