Hi all,
  A friend has a little problem with some TK-50 tapes... Yeah, he put them
in a drive,:-( , and the drive SEEMS to have erased the header/pre-amble
from the tapes the drive has ee replaced and now he can't read the tapes.

So, is it AT ALL possile to recover the its off the tapes i this case?
Can the TK-50 be conned into reading the tape and ignoring the lack of
pre-amble? Can someone in DEC do this for them if need be? They have
a lot of mass-spectrometer data they realy would like back.

Reply by mail, will summarize...

Several people have replied, but all seemed to have missed the point, we can
read ANY bits off the tape... In fact we can even get it to set the ' volume
valid ' bit to mount it.

So, is it possible to set a TMSCP equivalent of the disk ' allow self destruct'
unit online comand? or some such. Is there any way to force the drive to keep
going in spite of 'fatal' errors?
