The av removed all the dropped files. Then one day, files with names similar to old names were dropped and av could not detect them even in aggressive mode. But, I used Norton power erase to kill those files. It seems they crypted it to avoid av.
Anyway, I decided to go for a full erasure. I quickly decided to do a dban erase.
Its going on now and will take about 7 hours. Method is prng 8 passes. I am on the 6th pass now.
I have the following questions -
1 - Can I just stop before it completes ? I feel 6 is enough ? Should I eject the CD ?
2 - Some malware are known to hide in "secret areas" of the hard disk as mentioned in two links. It seems that dB an does not cover these secret areas. So a root kit that resides there can evade dBan too.
So, is there a tool which can do a 100% erase ? Preferably free/open source.
Links about dban limits -
3 - What are the things one needs to be aware of to ensure a full erase or for selecting a full erase tool ? Eg. MBR, HPA and all that kind of stuff.
I am posting this from a mobile phone, so please adjust.
