it's been so long since we got those particular arrays that I'm not<br>
entirely sure. The arrays came from a source I would expect would be<br>
pretty concerned about data. That said we still wipe drives regardless<br>
of what people tell us (for our own peace of mind). We held off trying<br>
to wipe those particular drives since the control unit for the fibre<br>
channel drives apparently has some software issues.<br>
<br>
Paul, I thought I'd mention that we sprung for PartedMagic, so in<br>
addition to dBan we've started using that for SSD's and the like.<br>
(I've already put it on the PXE server).<br>
<br>
If you happen to drop those off Ron just make sure you ask for either<br>
Martin, Charles, Kirk, or Berleine [our IT dept] (Paul still does a<br>
lot of work for us, but he's not often on site). The official address<br>
is 58 Queen Street south. Computer Recycling has a door on the corner<br>
of Queen and Charles street, directly across from Full Circle Foods<br>
health store (Charles street). If you happen to have a bit of time I'd<br>
be happy to show you the arrays.<br>
<br>
We've definitely run into that time issue, we had a client that asked<br>
for an 8 pass RCMP standard for a 1TB drive and that took a couple of<br>
days. We haven't used PartedMagic a lot, but I hear it might be a bit<br>
quicker than DBan. The price for a single license was really cheap,<br>
something like $14.<br>
<br>
Paul, really appreciate this as this is one of those priority things<br>
that just always kept getting shelved dealing with the daily grind and<br>
other projects!<br>

Most of the >8yo FC arrays were along the lines of 2tb-4tb of raw storage that sucks some 120w-150w depending on speeds of the HDDs. Those 10KRPM HDDs are power-hungry.<br>

> 4 - The fact that you have drive arrays in this privacy-aware world is surprising. My IT shop regularly get some of this older stuff with the raid array scrubbed, but scrubbed poorly since an 8-drive 2.4tb(raw) array takes about 4 days to complete a 3-pass DOD-type scrub. We are tasked with destroying said array, we do that by drilling the hell out of the drives so that the platters become a mess of broken glassy bits.<br>
