Why Is My Program A Bad Driver?

Q. As the owner of a Spectrum 48K I have just purchased a Wafadrive. Could you pleaase tell me why a program should load and run perfectly well in drive A, but comes up with a 'bad sector' error every time on drive B?

K. Sanby, Lincoln, Lincs.

A. Your problem sounds as if it's related to the heads of one of the drives being out of alignment or - less likely - speed variations between the two drives. Try saving a program on drive A then reloading it from drive B, then vice versa. If you can save a program on B and load it from drive B, and save one on A and load it from A, but can't switch between the two, it's almost certainly an alignment problem.

If this is the case you should be able to get the drive exchanged by your dealer.
