This problem apparently is a result of the newer drives having (and needing) weaker magnetic fields to prevent scrambling of data at close densities. The 800K drives, which have stronger magnetic fields, can not be read with the weaker magnetic field off of the new drives. On the other hand, since it appears that the machines are using the same disks (or rather the same type of drive), this may not be your problem... =Edwin Aoki =aoki@husc9.harvard.edu - Std. disclaimers apply COMING SOON!
