Recovering damaged ZIP archive

'Unable to unarchive. Error 1 (Operation not permitted.)'.

Just a thought - are you trying to unzip it from the DVD? If so, the software might be trying to write to the DVD rather than the hard drive - that might cause the Operation not permitted error.

Then that wasn't it. 😟 Have you tried using BetterZip? If will display the file list of an archive so you can manually choose which files to unarchive. If your archive's file list structure isn't damaged, that should let you retrieve some of the data. If the data structure is damaged though I don't know if anything can be done.

Hi James Bachman;

If you are correct there is no password but BetterZip thinks there is one, then the archive has gotten so corrupted that there is no chance of recovering anything from it.

In my years of IT support I can't tell you how many time users have come to me with the problems of corrupt archives. Some of the users were claiming that if they didn't get back their data it would be the end of the world. They didn't get back their data, even the ones with enough horsepower to request the archive be sent off to data recovery service.

I am trying to expand a Stuffit ZIP file I created of personal family images/information. I thought it was a good idea at the time (yes I could just shoot myself). All I did was compress it and it was saved on an external HD. Well sometime later (few months maybe years) I want to open it and use some info on it and I can't.


I found some help stuff on this site for logging into Terminal. I got this when using Terminal after prompting the Error 1 - Operation Not Permitted. Read below and PLEASE (yes, please) help me figure out. I've tried some things from the list but since I don't know what I am doing I need mac geek assistance. I am partial geek, hehe. Thank you!

Everything else gave me an "Error 1".

Cheers!

Do you still have the DVD? Try copying the ZIP from the DVD to a hard drive and then extracting it. Make sure you're not extracting to the DVD.
