ADAT XT error 7

Archived from groups: rec.audio.pro (More info?)

Having the same problem with 2 XT's. Very low hours. Cleaned the heads.
Is there a fairly simple solution?

Would appreciate some thoughts as well.

Thanks,

Error 7 means there is an excessively high block error rate. It can
be caused by nearly anything.

Clogged heads can do it, but so can poor tape to head contact from
a bad idler. It can even be a bad tape. A popular source of problems
is the connector on the linear head, which becomes corroded and loose.

It can also be caused by the dreaded head preamp chip failure. Just
about anything from very minor to very serious can cause the problem
and you don't know what it is until you clean the tape path, lube the
transport, make sure the rubber is in good shape and start poking around
test points with a scope.

She just came back from the shop. They said it was electronically way
out of adjustment. I don't know why that would be as it hasn't been
used..... They cleaned it and set all the electronics to within their
parameters... I will hook it back up and try it tomorrow.... My
second one exhibited te same problem. I cleaned it and it worked...

Error 7 can mean many things as follows.....

#1: It could mean you are using a 20 bit formated ADAT tape on a older 16 bit ADAT machine, this will result in an error 7 or another error possibly.

#2: It could mean dirty lousy el' cheapo' SVHS tape, so use good quality SVHS tape only!!! And then check with a good recorded SVHS tape that you knew worked perfect last time, and then try another tape just in case, and if you still get error 7 then you need to clean your ADAT rotary head.

And while your at it, clean/lube the entire transport too. For instructions on how to do this, do a Google search, and it is important to do the lube and cleaning job properly, otherwise you have an expensive ADAT paper weight machine!!! You can damage the rotary heads and transport if not done right, so be careful and do it right and or bring it in to a good technician who knows ADAT machines, do not bring it in to any technician, I have had technicians ruin ADAT rotary heads before. I want to beat some technician up badly.......
