Greetings, this would be my 1st post; thank you for taking the time to view it. This may be a rather technical question: I am trying to completely zero out my hard drive, so that I may sell it. It is a good Seagate HDD. I understand the process of "erasing" the data pretty well, and I will here give the quick and dirty outline of what I do so there can be no confusion: 1) I hit "option" at start up chime. 2) I insert OS X download CD disc, and choose to boot from the CD. 3) I go to Disk Utility and I select my HDD and choose "erase". 4) I choose recommended "zero-out" option. 5) I erase the entire disk including all partitions. 6) I wait... 8) I am done, the disk is empty. Here is where I am confused however. At the bottom of the "Disk Utility" window, I am presented with all the basic information regarding my new blank "partition" on my HDD. There are various categories with corresponding data points. The two I am confused with are thus, and it is because they read out the following data points: Number of Folders: 3 Number of Files: 2 My question is, shouldn't there be 0 folders, and 0 files? If not, what are these files, and why are they necessary? I don't want there to be any data from the HDD previous life left over for obvious reasons, especially any personally identifiable data. Is this normal? Because it also happens on my other drives, albeit a different number of folders and files. I don't understand why it would be necessary for there to be any data left over on the HDD, since it seems to me to be a primarily "hard" technology without any real need of software, at least until an OS is downloaded unto it. Also when I choose "open disk image" from the menu bar, in order to open the partition for perusal, I can't find any folders or files on it. So what could this information be? Hidden data logs? Thanks for your time.
