Formatting Question for External Hard Drives

post #1 of 17
Thread Starter 
I know how to format an external hard drive in disk management, but that only gives quick format options. I have two external hard drives. A Western Digital 250GB and a SeaGate 320GB. I want to format them appropriately to be able to sell them. Not sure how much I would get on something like ebay or Craigslist, but some money is better than no money at all as I use smaller laptop size external media or flash drives now. Or simply cloud technology. So if I am going to sell these I don't want someone having access to my information on these drives. I quick formatted them a few times, but is there something more I should do?

You need to run a secure erase on them. Here is one that is free called "Eraser"

you need to wipe them... even with a full format the old data can be easily recovered.

Eraser in the above post will work fine... KillDisk also has a free version...

I prefer DBAN for nuking drives. I use the 7-pass DoD 5220-22.M, but at least do the 3-pass version.

yeah... I don't know why I forgot about dban right before you posted.... yet another good one..... well.... that will about do it I guess.... not sure which is best, but I imagine they all do about the same thing... .using Window 7 64 bit if that makes any difference.

Eraser openly supports 7, and it doesn't matter if you're booting to DBAN.

Any tips on this one? Which method do you typically use?

They all pretty much use the same algorithms. Like I said, I prefer DoD 5220-22.M. The others seem either too light or overkill.

If it's good enough for the government, it's good enough for me.

3 or 7 pass - take your pick. I always use the 7-pass to be on the safe side.

I selected unused space and selected the external drive (because I already ran quick formats). And it finished within seconds. Is that normal?

It keeps telling me the following:

Sunday, July 24, 2011 8:45:43 PMErrorThe program does not have the required permissions to erase the unused space on disk. Run the program as an administrator and retry the operation.
Yet I ran it as administrator.
