hi all... again. Well, i've hit another brick wall in my 9100 upgrade and was wondering if anyone else has come across this before. Basically, the 9100 is refusing to write to the hard disk... i'm getting 'write error' every time i try either to copy DR1 to HDR, or even saving a calibration/settings file to HDR... the story so far: It all went wrong when i booted my 9100 from system 6.0 floppies, and copied all three system disks DR1 to HDR... when rebooted, the 9100 failed to load, throwing up a mixture of Error loading OS F7, or OS F4, and then proceeding with ERROR 244 or ERROR 205 and prompting to continue through a mire of root software errors. end result, the machine hung after the last error 'application exited abnormally internal error 102' - if anyone wants a full list of error codes, let me know... So, someone suggested formatting the hard disk, booting from floppies, and copying them over again... so i duly booted from the service disk, and formatted the drive, choosing option 5 - no dma. two options, 4 dma, 5 no dma... wasn't sure what to pick and couldn't find any info in the manuals about this. picked 5, and formatted. After doing a physical format / verification, results were : 74 bad (sectors) - 19.13mb available. I booted the v6.0 floppies and went to copy DR1 to HDR, and immediately got a write error.... So i got bored and I upgraded the roms in my machine (from 27256 V3.0 to 27c512 V5.0) thinking it might help, can't make the problem worse i thought :) I then retried the process again and it still failed.. So i checked if this was a system disk copying problem, or a general hard disk writing problem, i went into 'setup | save system settings in userdisk' and got the very same write error, indicating it must be a global hdisk writing error, not a problem with just the disk copying section. So then i booted to the service disk, and formatted the hard disk once again, but this time took option 4 - dma... same as above, booted in from floppies and i still get the write error. I have the western digital interface and the miniscribe 8254 drive, cannon floppy, and 2mb ram, i have set the config options correctly from the service disk utility, and tried numerous times copying to hard disk, with this write error all the time now.. i even made up a set of old 4.1(b) system disks (this was what my system had on it before) and tried the same things, and still this write error.. I turned on the disk error reporting from the service disk, and when i get the write error now, it shows the address as 00000001 so its the very first write it is failing on each time.. Bearing in mind the drive still appears to format ok, and that i had no previous problems with it, do you think this write error is the drive, or the controller, or the software mis reporting it? any help appreciated, or i'm going to be reduced to manually loading the system software from floppy disks everytime i want to use the damn thing, which will be a real pain as i do use the 9100 almost on a daily basis. ta, Andy. _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
