[comp.sys.amiga.hardware] sq555 hard drive prob

4/10/90 syquest sq555 problems

equip:

   amiga 2000
   1 IVS trump card
   1 internal sq555 drive 44M
   1 external sq555
   1 cartridge DH0: = disk1:
   1 cartridge DH0: = disk2:
   1 cartridge DH1: = disk3: 

history:

   disk1: ~20M full, normal boot disk
   disk2: older copy of disk1:
   disk3: mostly empty, nothing important

onset:

   operating with just the internal hard drive, using lattice 5.04 lse
   just saved file, shut off hard drive only, computer still on
   back after a long while, alert disk1 read write error
   spun up disk and retried, bombed, acces light stays on, sounds emit
   reboot, access light stays on, sounds emit
   turn on external with disk1: internal with disk2:, reboot
      had to turn on external later, if too early bomb as above
      if too late would not mount, no disk icon in workbench
      got it to go just once:
	  error disk1:, retry
	  error validating key 40759, bad header type
          grab important files, seem ok (whew!)
   disk3: in internal, disk2: in external (so DH1: mounts ok), reboot
   put disksalv and stuff in RAM:, disksalv DH1: DH0:
   put disk1: in external, Y at prompt for disksalv:
	  builds directory, wome block key mismatches noted (79225 != 38756)
	  starts writing to disk3:, bombs (screen go crazy)
   disk3: in internal only reboot, run virusx 3.2:
          ColdCapture pointing to $FE7B0, possible new virus
   files from disksalv on disk3: are either 488 or 0 bytes 

what next:

   going to mrbackup disk2: to floppies

help:
  
   does this sound like a new virus, or perhaps a mishap cosmic ray
   that randomly changed the wrong 1 into a wrong 0. how about disk1: ?
   gone for good? what's ColdCapture to $FE7B0? how can i isolate a
   possible virus? maybe virusx 4.0 could help. I don't know, do you?

thanks for any replies, ric@hpspd
