I have + a ST-251 disk (non-SCSI) that I have been using for over a year. + Just recently I am trying to recover from file system problems. + I am trying to format the disk (FFS) and I keep getting guru'd + before the format completes. The Guru is typically a 3 or a 4 + (addressing or memory error) and is inconsistent. There are a vew basic things you can try, hardware wise. If you're like me you've got a memory expansion card (I've got a Spirit board). Depending on your environment and how often you turn your mahcine on/off you might be suffering from chip-movement. This is where the chips start to move out of their sockets (if they have sockets). Try opening your machine up and pushing down on all the socketed chips (or if you don't like to open your machine up, take it to a dealer). Another thing is re-seat the controller card in it's slot. Another thing comes to mind: I have s Supra 4x4 20Mb drive & controller. The original device driver (harddisk.device) would crash depending on how much multitasking I did. I fixed it be getting the upgrade to the device driver from my local dealer (supradirect.device). Since then I haven't had any problems. Maybe you can get an update for yours from your dealer or from Commodore. + + Also, the one time I did get thru the format and tried to do a restore + from backup floppies (Quarterback) I repeatedly get Guru'd before + the restore completes (also incosistent). + + Any advice?? Upgrade to the 2090A controller?? + + Thanks in advance, + Peter Meng + att!hotlf!pfm Hope this helps. -- Peter A. Castro INTERNET: peter@dbaccess.com // //| c/o DB Access Inc.
