If it doesn't lock up with a colored screen, I get following error message:"System Error ($0001) This Operation cannot be completed. Bad System Call Number." Any idea what that could mean in this context?Others with more GSOS experience may be able to provide more pertinent information. I'm assuming that these errors occur during a long operation. RAM errors can appear to be virtually anything. If your system is failing occasionally, it could be almost anything that is causing it to operate marginally. Power supply degradation or higher operating temperature are two things that come immediately to mind. Attack intermittents by making changes in the setup and seeing if the error frequency changes. For example, remove the top of the computer to lower its internal temperature and try again. Or remove some unneeded cards/devices and try again. If you find some change that makes the errors disappear and re-appear, that can be a useful indicator of the cause of the problem. -michael
Thank you Michael.Seems like the three areas of concern might be Memory, Heat, and Power. I just don't think it is heat related, and while I'd like to put in a Buggy Power Supply, I don't know where to get one these days. I did swap the 4 meg memory card for a Q-Ram card I had. (Both the new and the old pass a BitBanger test). Seemed to make a big difference. I went a day and a half with only two "Bad System Call" errors.
Just now I got a new one: System Error ($0051) Directory is damaged. I can't even delete the bad directory. I did manage to re-name it (I guess HFS lets you do that) and am continuing.
Hardware includes: Rom 03 GS, ZipGS @ 8 mh, Ramfast D, 3 drives on a SCSI chain, and a System Saver. I'm shift booting to maximize free memory.
In terms of what has changed, I did add the Sonic Blaster card a few months ago and this is the first time I've tried to run with so many SCSI devices in the chain (although I've cut back to three in my latest attempts.
Any suggestions on how to get rid of the "Directory is Damaged" problem? I'd just be happy to delete it, if I could.
