We are asked to wipe hard drives from a huge STORAGE system which is RAID structured. So, we can either wipe each drive individually(which will take a lot of time) or we can wipe the storage area without actually removing drives from the RAID and do the wiping within RAID.
What do you think the best way would be, to wipe drives individually or to wipe them as a whole in RAID?
Another option is to use a degausser, which gives huge magnetic area to the hard drive and removes any structure on the disk, however, this option makes drives unusable. So, we do not want to go for it.
Is there any other way to wipe all disks quickly and securely?

Hi Yunus,
I have some experience on this as over the past years I helped to implement mass wipe systems on different companies. The main issue on a secure wipe process is to keep control of what is going on. That means that in case of an eventual loss of power you should be able to know which drives have been completely erased and which ones have not. You should also be sure that progress information is real. That means that what you are shown to be erased is actually erased, without any misleading information due to RAID controller cache or anything like that. In my opinion, if the wipe process you need to perform is critical (and normally all of them are), you should use the services of a specialized company as Recovery Labs (
I hope I helped. Best regards!!!
Are there any non-RAID partitions, parts, areas on any of the drives? If you answer "yes", I would do them individually, otherwise through the RAID.
If the entirety of each drive is a part of the RAID array, what would be the downside to just wiping the entirety of the array using sdelete, eraser or something to that affect?
