So, if you want to erase the data but keep the drives operational too, you
have but one means left: by plain old formatting. Depending on the level of
security you want, you can opt for:
* DOS/Windows format (beware: this does not erase ANY data at all !!)
* Low-level format / wipe (with special tools, level depends on the tool used)
* Linux dd overwriting using /dev/zero (fairly good if used multiple times)
* Linux dd overwriting using random data (excellent if used multiple times)
* Department-of-defense level (dd as above but lots more times (like 10+))
0. Manuallty wipe (shred, wipe, PGPs secure deletion utility, ...) files that
you know contains info you dont want to share.
1. Remove all partitions (fdisk on a floppy).
2. Create a new partition covering the whole disk and reformat it.
3. Use Autoclave or write your own, similar but updated, tool.
