Hi David,

I considered that microdrives are available but the question for them is what
field strength is necessary to cause damage? and what field strength are they
subjected to in an xray machine.

Everyone should keep in mind that magnetic fields around xray machines are
generated by the hardware generating xrays. In other words xrays themself are
not magnetic fields.
