It depends on how thoroughly the hard drive was erased.
The first level of erasing a hard drive just wipes out the directory, which is basically an index, telling where on the drive each file is physically located. Wiping out the directory leaves all the information in the files on the disk, but somewhat more difficult to retrieve, since you no longer know that the file xyzomg.pdq starts at sector #247,318. There are software packages and commercial services that can retrieve most of the data from a hard drive that has been erased this way.
The next level of erasing a hard drive is to write new data over the old files. The more times you do that, the more difficult it is to retrieve any of the original data at all from the drive. It's akin to erasing something written on a chalkboard or marker board and then writing something else and erasing that, possibly repeating the process a few times, and then trying to read the original writing.
