I had to look up HIPAA as i didn't know what it was. Maybe it's country specific?

I suspected you were wanting to sell the unit/s and if it's sensative data then i can understand your reasoning for wanting wipe them.

For what it's worth, most people are not experts in data recovery, especially after data has already been erased, so to speak. I would deffinitely advise deleting the raid set and re-building a new set as a precautionary measure but i can't see that you would need to go to anything more extreme.

From what i understand, building a raid 5 set for example, takes several hours or even days in some cases if the drives are large enough. I'm fairly sure that because of the length of time involved, the original data is being properly ereased and the drives are reformatted/repartitioned etc properly by GOS.

Maybe specialist computer phorensics could recover the data but even then i suspect the data would be gone.

I've bought a couple of second hand snaps in the past, some with data still on them and to be honest the first thing i do is get rid of the data, it's of no use to me or of any value to most people, it's just taking up space that average joe wants to use to store their own files.

Some people are super paranoid of course but i think it can be a bit extreme in some cases. Organisations literally sledge hammering the drives after erasing them. It's a waste of good useable equipment and such a shame.

Oh and i forgot to add, if you erase the drives as i suggested, try yourself and see if you can get any of the data back. Data is a lot easier to loose than it is to recover IMO

Goodluck.
