I'd like to know what's the best way to completely wipe the hard drive of a My Book World Edition, because I'm not using it anymore and therefore I'd like to use it as an internal HDD for my computer.
That's what I did in the end, but I had to use a Ubuntu live CD in order to format it. However I can't get a full tera out of it, just 936Gb, is that normal?
If you used the Ubuntu CD to partition it into one single partition, then yes. It is not uncommon for rather large amount of room to be devoted to overhead and one also has to consider the true size of the drive (GB vs GiB).
Here is a link discussion the GB vs GiB issue
Is it possible to do a secure erase of the drive and still maintain the Linux partition? I want to sell mine and need to write zeros to the drive.
in order to zero all the drive, you can
perform a firmware upgrade, to wipe the system partition,
launch the following command :
this will create a very big file "dumpfile" in the /shares/publuc folder.
the file will take all the disk space.
then, the rm dumpfile command will delete the file…
if you are paranoid, you can also launch :
this will fill the file with random values… making it impossible for anyone to retrieve any data from the disk…
Many thanks of this info but I decided to pull the drive from the enclosure and use it in my Mac for additional storage. Nuke it using Mac Disk Utility. Took seven hours to zero out. Now have nice, empty enclosure that needs a new home. Will give away for free if somebody wants to pay nominal shipping. Thanks again and let me know if you are interested.
