Message-ID: <483@spdcc.UUCP> Date: Fri, 2-Jan-87 22:44:13 EST Article-I.D.: spdcc.483 Posted: Fri Jan 2 22:44:13 1987 Date-Received: Sat, 3-Jan-87 02:42:38 EST Organization: S.P. Dyer Computer Consulting, Cambridge MA Lines: 31 Summary: up the creek without the sources Here's the scenario... I had a 30meg disk of sources as a second drive on my AT clone which I backed up onto high-density floppies using the SCO XENIX 'backup' command (basically a version of dump.) The command was: backup 0uk 1024 (the default file system to back up was /dev/src, the disk in question.) 33 error-free diskettes later, I removed this disk drive and went through all the procedures to install a Seagate 80 meg drive, split into 2 40 meg partitions. An fsck on both newly-created partitions looked fine. I then invoked 'restor r /dev/src', /dev/src now pointing to one of these 40 meg partitions. Quite often during the restor process, I got the error message 'Missing address (header) block'. This is coming from the restor program and not from the kernel. 33 diskettes later, I performed an fsck on the new file system, and got an incredible number of unreferenced files and when I tried compiling News 2.10.3, I was dismayed to find mod.recipes documentation in the middle of control.c. There was similar trash scattered around elsewhere. Clearly, the process had been useless. Does anyone know what this error for restor means, and whether it was responsible for the problems I am having now? I still have the old disk around, but I want to know what went wrong before I start scraping my knuckles to reinstall the disk and have to sit through changing 33 floppies all over again, especially if it isn't going to work again! -- Steve Dyer dyer@harvard.HARVARD.EDU {linus,wanginst,bbnccv,harvard,ima,ihnp4}!spdcc!dyer
