Nickel Sensors Could Raise Hard Disk Capacity
Makarand writes "Tiny filaments of nickel, thinner than a wavelength of visible light, acting as magnetic
sensors may expand the storage capacity of hard disks many times. Although, technologies
exist to increase hard disk capacity, reading data bits reliably from such disks has proven
difficult because as data bits become smaller their magnetic fields are weaker and difficult
to pick up. Nickel filaments are capable of picking up of these weak magnetic fields
using a phenomenon called "ballistic magnetoresistance" which is not completely understood.
As the sensors are only a few atoms wide the electrons travel along a straight line
in the conductor greatly enhancing the binary signal picked up from the data bits.
These sensors could also be used to detect biomolecules in low concentrations."

Then how do we know they're there?
If I had a nickel for every time...
Velociraptor = Distiraptor / Timeraptor
Last time a drive failed on me, I made it go ballistic too, and it offered little resistance (however the concrete offered considerable resistance). Is this a similar thing?
There was a brief time a few decades ago when the essence of my entire being was contained in a single molecule, with no backups! Luckily, I made it through that episode relatively unscathed.
Ever since then, I've been making backups like crazy.

I'm yet to make any fully redundant backups myself as opposed to your incremental ones, however I fear there may have %50 data loss in any such backups and the data space will have to be shared with someone elses.
