Or for a little more (I think they're like 140 pounds now) you can get a
blu-ray writer. Those discs take 50GB each if you get the dual layer ones.

Really? I knew BluRay was higher capacity, but I didn't know it was
quite that much...

At one point we were going to use it at work (although nobody I spoke to
could tell me what it's supposed to do or why we need it or what we
would use it for beyond "sharing stuff").

It's useful if you have groups of people working on documents. Rather than
sending various versions by mail, you put them into sharepoint. Sharepoint
(even the free version) has versioning and checkout/checkin of documents, as
well as tracking who made what changes and workflow (so the system can mail
someone when a document is uploaded, make a copy somewhere when the document
is 'approved', prevent changes while it's in a certain status, etc)
It's a quick and easy to build intranet portal. No web design/developmetn
skills are required to edit lists in sharepoint, so the secretary can add
news items, calendar entries, announcements and the like

We have purchased a "document control system" that we use to store all
our procedure documents and revise/approve them, etc. It's not a very
*good* system, but there we are. (It's very over-complicated for what it
actually does. And yet, at the same time, it's very inflexible. It will
only do things in a certain way, etc.)
It used to be a client/server package (which was quite slow), but now
it's web-based (which is even slower). One nice feature is that you must
manually turn off web caching on your browser, and disable all web
caching between your machine and the web server, or the thing
malfunctions. (In other words, the designers don't know how to write web
apps properly.) Also only works with specific combinations of Java and
Acrobat.
Still, I guess I should think myself lucky. It can't be long now before
they move it to Terminal Services, and then I'll have a huge raft of
*new* problems to worry about...
This is perhaps why we never did get Sharepoint.

Oh, I remember that. It's Microsoft Drupal, basically. :-)

Software. Real HW-RAID costs incredible amounts of money and software is

It was some random bulk-card and I'd doubt how hardware based it
actually was, but since RAID-1 is only a mirroring, it's possible to do
cheaply.

Yes. It was the time when 120MB disk died and it was worthy enough to
try to rewake (yes, I succeeded).

OTOH today you can format multiple drives at once without significant
loss in time.

Yes. Formatting to ext3 or XFS takes a moment more, since the system
also creates journaling ;).

Linux keeps the software-RAID-1 block-by-block -identical also - and it
drops the disk from the array if it can't do that. What it doesn't do is
dropping the disk from the array if it works, so if you'll get a drop,
you know you're going to have a need to replace that drive - either
immediality or really soon.

Do backups ever seem like gaining a huge amount? Think again. How does
external HD differ from LTO-tape in
1) in virus-case, when all online files are compromised or deleted
2) when your running data-disk breaks up
3) when you'll accidentally press "delete"
4) when the flood comes through your roof
5) when some looney robs your laptop
And yes, if your house burns down or your roofs gives up and lets the
water in, you do have a bigger problem than your binary data. But it
doesn't remove the dataloss being a problem, it just cumulates all other
problems on top of it.

NTFS also creates journaling. The actual difference is that ext2 and
ext3 preallocate all the inodes, while NTFS doesn't.

I would have to disagree with you there.

I disagree. Fixing your house is just money. Getting back the vacation
photos, or the photos of people who are no longer alive, is much more
difficult. :-)

Well that's what I'd figure...

Well he got a newer motherboard where the chipset throws in a RAID
function just for fun (this seems to be very common now), and had the
exact same problem. (Despite it being an unrelated machine with
unrelated drives.)

That's true. Although I've never yet had occasion to need to format
multiple drives in the same day. ;-)

This is where the system my dad had failed; it would randomly drop
drives for no apparent reason. Once he turned RAID off completely, all
the drives worked just fine. Go figure.

Because the LTO system we have at work involves the tapes being put in a
fire resistant safe in a remote location. ;-) Obviously, a home user
with an external HD isn't going to do this.

...it just means that that problem is dwarfed by all the other ones! :-D

...like pictures of the people who were in the house while it was burning?
