Allocation unit size (formatting a HDD)
I saw someone post online they needed to get an external HDD to back up files because their computer keeps shutting off on them out of the blue and they are afraid that their computer is about to die. I have this 250 GB external HDD (232 GB available) that was given to me for free and I just don't need it and don't use it (I have a 1 TB external HDD). So I decided to help them out and will mail the HDD to them. I want to format the HDD, as I have some personal things on there (photos of me and some friends and family, and some word documents with personal info).
I'm trying to decide on what allocation unit size to choose. I found this link: http://www.howtogeek.com/136078/what...en-formatting/ Most of the data on this external HDD is about 95 GB of anime fansubs and about 29 GB of music files (these things were backed up to my 1 TB external HDD). So according to that link, I should set the allocation unit size to the biggest one? That is what I should do? Is there any problem with choosing the default size (4096 bytes)? A couple more questions. No matter what allocation unit size I use, it should clear all personal data away permanently, right? Also, this external HDD comes with some folders, apps, and files needed to make the device operate/function correctly (examples, a "Seagate folder", a Settings file). If I format this HDD, these things should automatically be safe from being erased, right? Just figured I'd ask.

The data on your drive will be deleted, so there's no point in using it to calculate which allocation size to choose. Let the person you're giving the drive decide if he/she wants a different allocation size. Quote:
It will be erased in the sense that the computer will show it has no data and most people would just trust that it's empty and won't try to look for your data. But unless you actually overwrite the data, there is some software that could try to recover it and knowledgeable people might use those programs to look for any data they can recover. So if you have data on the drive that you don't want other people to recover, then overwrite it. Otherwise, if you don't care, just format it and it will be gone as far as many people are concerned.

But the drive itself should still be usable. If the person you're giving the drive to wants those software back, he might try downloading it from the manufacturer's website. |

So how could I overwrite data?
Would it be a good idea to edit and modify certain pics and certain word documents? I could take pictures with me, friends, and family and then just crop the picture to a small segment of the picture (a part with no person, like a counter or a tree or a shoe) and then for written documents, I could just use Select All, delete, and then type in something like "blank document" and then save the document. Then I could format the hard drive. In the event someone down the line gets my hard drive that wants to recover the data, all the personal info would be edited so that nothing personal is there to see. Would this idea work?

If you're using Windows, you can format the drive and then run the following command in the command prompt:
Code:
cipher /w:E:\ Just make sure to format the drive first and to change E to the current drive letter of your drive. Or just search for other tools for Windows and/or other operating systems. Quote:

Okay, so if the external HDD is something like drive 'F', just make sure to run the command [cipher /w:F:\], correct? I wouldn't wanna do that to my actual E drive, that is my storage drive with my fansubs and music lol

But you should be able to run it safely on any drive because this command only overwrites available unused disk space. I've even done it on my C drive. That's why I said to format the external drive first so that the whole drive will be unused, and thus, will be overwritten by this command. Ah, I forgot, I don't know if the cipher command is available in the home editions of Windows. I know it's available in the pro/business editions. |

I formatted it. I am now running a drive wiper with the program CCleaner. It gave 4 options. Simple wipe with one sweep, Advanced with three sweeps, Complex with seven sweeps, and Very Complex with 35 sweeps. I chose the one with three sweeps. I figured that would be good enough. Will take about six hours to do, too. Has about 5 hours and 20 minutes left in the estimated time left message.

What I did was a format (not a quick one) and then did a drive wipe with CCleaner, went to bed, and it was done in the morning. And now everything is taken care of. But...that drive wipe wasn't necessary, was it? All I needed was the complete format (not the quick one)?
