    Ah, we're talking about spinning metal now. Ok then.

    Yeah, I guess I didn't make that clear before, sorry. (Didn't know for sure myself until after I made that Pakled post.)

    I’m in! Quick, how do I change permissions?

    Edit: NVM, found that bit online. It’s changing them...very...slowly...and some of them are clearly broken.

    right click on the folder
    go to properties -> Security -> Advanced

    up the top is listed the folder owner.

    Change it to your current account (in the window that appears start typing in your login name then click check name).

    down the bottom check the option to enable inheritance and then replace child permissions.

    This will then work down the directory structure and give you full ownership on the folders.

    Wow it’s like EVERY file in the Dell Supprt/Assist folder is corrupted and unreadable.

    And DAMN are there a LOT of files in there. Fucking hell, do I seriously have to click “continue” for EVERY FILE in this folder? How many thousand IS that???

    I give up. I found I was able to get to the Users folder, and see Julie’s folder, but I needed to open permissions for that, and when I did... I spent 20 minutes rapid-clicking as fast as I could get my hand to twitch (deliberately tweaking a nerve, that’s pretty fast, like 20 times a second) and I couldn’t even get through her “Apps Data” folder. I saw a couple of files that might have been familiar, but they too were corrupted. I have to say I think it’s a total loss. So much work for crap.

    Yrah it blows budgie balls but at least you know that things are definitely fubar'ed rather than wondering in the future if there was something that could be have been done.

    Time to recycle the drive.

    Unlikely anyone would be interested in or able to extract any data Crome the drive but I would drill through the to casing a few times before disposal.

    Postscript: Just before I packed it all away I remembered that I had another old HDD lying around. This one was from a computer that died before I bought my current one. Not only had it died, but I'd done my level best to destroy it - basically tore it out of the computer, and ran a fairly powerful magnet (used for finding nails as we drag it around the yard) over it several times. Then left it in a drawer directly above a heat return for three years.

    It worked perfectly. I pulled even OLDER itunes files that had been lost.
    Friday the 13th, man.

    So your external drive connector wasn't wasted after all.

    Now for the 3-2-1 rule so it doesn't happen again
    3 backups
    2 different media
    1 offsite

    I use external drives more to transport data to the backup machines, external drives are okay for backup but also can fall down the stairs or die another horrible death..

    If you want to destroy the data on a hard drive, you can try wiping the drive, reformatting, etc. But it's always going to leave something behind. I don't know why people don't mention this more often... but OVERWRITE (replace) is the best security. Start with a huge file. Maybe 10Gb. Copy it over again and again on a "wiped" drive. I can't see why this wouldn't work. Now you don't have to worry about destructive magnetism or physical damage (e.g. sledgehammer).

    or you simply get a program like DBAN which will nuke the drive nicely.

    Though if you're deadly serious about it, there's a degaussing unit that so's strong it will be pull the tracking off the platters.

    Heh, that reminds me of the mega junk yard magnet that Walter White and his crew use in Breaking Bad, to destroy a laptop held in evidence at a fortified police station. ;)
    Thanks for the tip about DBAN. I hadn't heard of it before. Makes total sense to have a Linux utility like this, essentially accomplishing that erasure by overwriting concept. :techman:
