Actually this is the only drive I've ever owned that didn't meet or exceed their specified number
		
		
	 
I wonder if yours had a lot of bad areas, which were marked off at the factory?
You could check out the SMART data using 
Everest. Under the Storage section, click on SMART. I believe that the ones to look for are Reallocated Sector/Event Count - check for what the Data column number is. Also look at the read/write error rates, which hopefully are 0. And of course, if anything's failing, then there's a problem.
There probably isn't any problem though - all drives have defects at manufacture. They're just safely marked as bad at the factory, and your drive acts like they're not there at all. I guess sometimes it just gets a little bit below the rated capacity. Of course, your drive is off by about 0.0017764352%. I guess that qualifies as "OK" with the QC folk.
		
 
		
	 
I was actually joking, I'm not exactly concerned about it being off - There could have been some minor space loss in the partitioning/formatting, and it is CLOSE enough to specified size, I can't complain, as long as it can cope with high operating temps (at least 46c if not higher.)
I did run that program anyways (looks an awful lot like aida32, and it only detects drives on the controller card just like aida did too)
If anything was marked as bad, it was done low level, the drive is only about a month old (maybe 2 weeks usage)
(smart data below - if quoting trim this up)

EDIT:  I'll actually add in something relevant to this thread 

My WD1200JB is partitioned into 2 drives, 55.8GB+55.8GB for a total of 111.6GB, those sizes are of course what windows says in properties.
