Endless Paradigm

Have two storage drives which developed bad sectors.
I've done a full format of them, and replaced the drives.

Thing is, now I've got two working drives which I don't have a use for.  I don't really trust my data on drives with bad sectors; although the full format should have marked the sectors as bad anyway, there's always the worry that more bad sectors will develop.

For those interested, the drives are both WD Greens, 1.5TB and 2TB capacity.

So what would you do with such drives?
Some possibilities (though of no use to me):
- temporary storage
- computer with non-critical data (eg HTPC where you just dump media onto)
- sending large collections to friends

sell them? im sure ebay will do fine most buyers don't check for bad sectors jsut storage size

I suppose, but then eBay does require some reputation.  Shipping harddrives isn't exactly cheap in Australia (cost me $30 to ship back a drive under warranty), and I doubt they'd sell for much though.
Probably the most I could do is stick up a local 'pick-up only' ad.

Drives show reallocated sectors in SMART info.
