How can I free 'hidden' hard drive capacity?
Agentless Backup is Not a Myth
I'm in the market for a new notebook hard drive. Replacing the old one is easy enough, but here's a thought: I've seen drives that offer 120GB and others that offer 160GB, yet both have one platter and two read/write heads. So, are they identical?
If they effectively are, can I buy the (cheaper) 120GB drive and access the 'missing' 40GB?
PS. I know these are unformatted capacities, but surely there has to be a way of accessing the 'hidden' capacity, no matter what it is.

bad sectors
Its possible that it was a 160, but the amount of bad sectors made it a 120, so at least they can sell something. I wouldn't try and get access as cost between the 2 is negligible.
Dunno...
But these guys are good and have some useful tools so maybe they can help?

It's possible
For certain specific models manufacturers have been known to artificially restrict capacity via use of a host protected area. I had an excelstore 60GB drive which was actually 80GB. I don't think it's a very common practice though, most drives are only capable of holding their rated amount of data.
