Emax

Bob vary well put...all drives can do both HD format and low DSDD format, but remember the Emax has a onboard FDC controller chip that is permanently set to low DSDD 720k format. This means it will always format at low DSDD power, it also means it will not read anything more than 720k of data even from a HD 1.44MB disc. You can not expect to get anymore storage other than 720k per disc.

  So did you format the HD floppy to the 780kb format with Omniflop?
  I am curious to try that. The drive I have in my EMAX II is a replacement drive from a PC, it should have enough power to write an HD floppy. : )

  Because the HD magnetic media (coating) requires more power to be written to than DDDS.

  If your DDDS drive does not have enough magnetic writing power the data you record will be unstable and stop working sooner than if written to DDDS disks (or not work at all... like one of our members found out).

  I myself have never had a problem with HD disks used as DSDD in my Emax II or in my many Atari ST computers over long periods of time.

  At this point it would be hard to say if you are better off using new HD disks or DDDS if the DDDS have been sitting on a shelf for 10+ years in unknown storage conditions (??? anybody?)

  Are DDDS disks still made new?
