Re: tape positioning

I think the problem is very simple.
Well it looks like you written over the old tape and it only has one set
I do this lots of times
Next time be sure to fsf the tape before writing new dumps to it .

OK. Mohamed come with me to wash up the next fast food floor :-)

I tested vdump on a clean tape, if you have a tape with the following layout:

r - record
* - tape mark

rrrrrrrrr*rrrrrrrrrrr*rrrrrrrrrr**

and you vdump on it

rrrrrrrrrrrr**rrrrrr*rrrrrrrrrrr**

you will get an i/o error if yout type "mt fsf 2"

Any other suggestion ?

Re: tape positioning

Hi,

have a look at mt seod. I am not quite sure what it does. It looks like it positions the tape at the end of data. Maybe you can use fsf or bsf depending on where the head is.

good luck,

Mr. Megyes Andras,
I don't know what is your problem regarding the message you posted " OK. Mohamed come with me to wash up the next fast food floor :-)", please explain it to me again.

Re: tape positioning

Mr. Megyes Andras,

Now, regarding your reply to me, I understand and I mean what I replied.
What I understood from your message is that you had a tape with several records,

rrrrrrrrr*rrrrrrrrrrr*rrrrrrrrrr*rrrrrrrr

But by accident, you wrote on it without fsf to the end of the tape.
Well by this you might have overwritten at the begining of the tape and the tape now has:

nnnnnnnnnnnnnnnn*

where n is a new record
and in this case you would get an I/O error if you type "mt fsf 2"
