Having used Unix and Aix very little, my company has asked that I pull information from tapes on the 3490e to the Aix system. I am using a dd command and thought that I had all the information correct but when I execute the command it says that I have an error in the input or output. The output is being created but nothing has been read into the new file. If anyone knows how to fix the comman please help.

dd if=/{pathname from 3490e} of={filename}.txt bs=128k conv=ascii fskip=1&

Thanks
 
Is readable that file? You can try simply [tt]cat file > /dev/null[/tt]

I hope it works...
 
jtr:

Parameter cbs (conversion block size (logical record length)) must be specified if ASCII conversion is used. It should be in multiples of 512. example: cbs=512

Try this - hope it helps. Al
 
I would like to thank you both for the excellent tips. It seemed the problem rested with the 3490e data disk drive. Somehow due to wear and tear or something the drive was not reading any data at all. After turning the machine off and then back on, and with a few modifications to my dd command, the data started to be read in correctly. Now I am just having trouble reading or tell if there are sequential files.

Thanks,
jtr
