Salut Tony,
Of course, I *can* degauss the
pack. The question is if I *must* degauss a pack before using it with
new track positions.
I think that's unlikely. There is a tunnel erase
head which essentially
wipes out any old data that might be picked up by the read head.
You mean that the
erased trace is guaranteed to be broader than the area that can be sensed by the
read head?
Do you know if the heads are good? I've had at
least one RK05 head that
tested OK electrically, looked clean, but which procuded no signal
Oh, I cleaned
them. And they look white. And I actually CAN read and write with both heads. But
there are errors from time to time. And the error frequency seemed to drop with every time
I format
the pack... Perhaps it's something at the write side... No idea.
I'll grab some heads and throw them at the drive. Then I'll try again. Currently I
have to find a
new blower for the unit 0 RK05 of my test system. It shorted and burned yesterday while
playing with
the rotten drive.
On the other hand that would mean that I'd have to degauss the pack before I ever
could use it
reliable again.
Since there's no servo infromation or anything like that on an
RK05 pack,
there is no reason why you can't degauss it. Do yuo have any more packs?
Of course.
If you get CRC errors at first which go
away if you format it a few times, it would apperar to be your suggestion
of old data causing problems.
If I had a degausser I'd immediately try it out.
I already thougt about a program that writes random data to the disk. Again, again, and
again. That
could level out the area around the tracks.
Another possibility: My idea is complete bullshit :-)
Best wishes,
Philipp :-)
