RE: Corrupt data?

If you look at the data sheet of any disc, you see "1 error in 10^15 bits". There are lots of bits on a 3TB disc, so there are bound to be many corrupted bits.

erm no, 10^15bits equate to 118 TB
So you'd have to fill the drive 37 times to get one bit error on average. Not a huge number but still, filling a 3TB drive 37 times takes a lot of time and if you're really worried you could just use ZFS.

No, I havent made myself clear. Let me try again.

It is not about filling up the drive 37 times. It is about how many bits you read. One day you read many bits, even though you may only have 100 GB data on your drive. And if you use a big raid from where you can read many bits each seconds, you have quite soon reached 10^15 bits.
