   Dear all,   
      
   I have recently re-acquired an Amiga 1200, which seems to be working very   
   nicely. I cleaned the floppy heads with some isopropyl alcohol and since then,   
   it has also been doing a good job reading floppies - to the point where this   
   feels fairly reliable again.   
      
   I've hit an issue though trying to transfer files via CrossDos from another   
   machine/OS, using PC formatted disks as a common medium. I format the drive as   
   PC0: on the Amiga, then verify the disk on the other machine where it seems   
   very happy. I can then open the disk, copy across the file of interest, and   
   again this all happens smoothly. The problem starts when I attempt to use the   
   floppy on the Amiga again. As soon as I insert it, I get this error:   
      
   "Error validating File Allocation Table to device PC0: Results uncertain.   
   Proceed at your own risk."   
      
   Sometimes, the file is there but it cannot copy across beyond a few bytes.   
   Sometimes, the file name is corrupt and I don't dare copy it. Sometimes, the   
   disk seems completely broken, with PCO:??? on the Workbench. If I then move it   
   back to the other machine/OS, it then says the disk is unformatted.   
      
   I don't think it's the floppy disk itself, as everything seemed smooth and   
   error free until that point of the error message. I wonder whether it's the   
   floppy drive on the non-Amiga, on both even, with issues of head alignment.   
      
   If it is, is there much that can be done to sort of the heads? What symptoms   
   do misaligned heads give?   
      
   Many thanks!
