Does a 7 Pass Hurt the drive?

post #1 of 4
Thread Starter 
Just curious, I read somewhere that if the disk is being used for a certain amount of time 24/7, it will hurt the drive.

Anyone have any information on the subject?

No, it will not.... but a 7 pass in unnecessary. No one is going to use an electron microscope on your HDD to recover a few percentage of data fragments.
Once again...

I single pass my HDDs before selling, and if I am extra paranoid (rarely) I double pass. From all the info out there on the web, there's something like a .1% chance of data recovery even on a single pass to 0/1/RAND.

Not necessary if your drive is less than 15 years old or so. A single pass of just about anything will suffice due to the way PRML works.
