This will probably require getting deeper into the guts of your laptop, but if you wish to avoid this you could first try to get a grip on the Hard Drive Bracket. The bracket is the thin piece of metal visible in step 5 of the Hard Drive Replacement Guide. The space between the hard drive and the laptop's lower case is very slim so you would need pliers or tweezers with wide and thin flat jaws. If the hard drive is out part way this will be easier. If the drive is still all the way in and if the tab tore off with some force it is unlikely that you will get enough grip to remove the hard drive.
If there is no way to grip the hard drive bracket then you can follow the Hard Drive Connector Guide to step 13. At that point you should be able to slide the hard drive out with out the white tab. This does require opening the case, a moderately difficult task. Look over the guide steps before you begin and look over the tools required for the job.
