I still need to take my IMac in to have the hard drive replaced under the recall notice. However, I am curious what steps those of you who have done this already took concerning data security? Did you delete files that contained sensitive info such as tax records, payments etc.. or did you just drop it off and let them swap the drive? I am not overly paranoid but I am cautious, so just looking for ideas of what steps others took before dropping their IMac off at the Apple Store. Thanks.
