Western Digital Security – a short story of a known password that doesn’t work

January 15, 2016 in Forensic Analysis, Silly

This is a short note to anyone who set up their password on their Western Digital drive using the ‘brilliant’ piece of software called WD Security and can’t unlock it, despite knowing the password.

If you know the password, but despite it being correct you can’t unlock the drive, it is possible you are using a very long password, longer than 25 characters. Turns out that when you set up a password the stupid software accepts password of any length, without limits. So, you enter your 30 characters password, set the password, unplug the drive, all happy. Then you plug it in again, provide your 30 character long password and to your horror, it doesn’t work. Try to input first 25 characters and it should hopefully work.

Updated appid_calc.pl

January 8, 2016 in appid_calc.pl, Forensic Analysis, Software Releases

I was recently contacted by Terry O. who spotted and reported a bug in appid_calc.pl which I released back in 2013. After analysis I realized that I made a stupid mistake in the way the parameters were passed to the functions responsible for APPID calculation. Oops.

I have updated the script yesterday and hopefully it should work now :)

You can download its latest version here.

Thanks to Terry for providing the feedback. This is much appreciated.
