I've been working on a move from 2TB to 3.0TB drive over the weekend and thought I'd discuss this topic. Now that I've "walked a mile in their shoes" I understand why drives are limited to 3TB. I don't understand why they chose to take this path to get to where they are, but that's another story for another day.
[
First off, they use MBR/MSDOS partitioning, yeah, good ole fdisk and all its limitations. So that means there is a 2TB limitation for any partition. You can have a > 2TB drive so long as the partitions don't exceed 2TB.
So here's the partition table from the 2.0TB drive I started with:
They've taken this drive and split into an odd configuration. There's a very small partition (sdc1, about 1GB) that is empty. I'm not sure what role it plays in things. Next, they build 2x 500GB partitions (sdc2+sdc3 @ 524280000) you'lll have to trust me that it comes out to 500GB in binary math.
This next part is where it gets funky... to avoid running out of primary partitions (sdc1+2+3 are primary partitions) they build partition 4 with the remainder of the disk as an extended partition. This is inherently limited to 2TB because we're using fdisk. That's reason 1 for the 3TB disk limit.
We still have unused space on the disk, because they keep carving up the disk within the extended partition. So, we have a 500GB partition (sdc5) and a ~375GB (sdc6) partition within the extended partition.
When you move over to a 3TB drive, you run into the next limitation, which is no more than 8 partitions on an MBR/MSDOS partitioned disk. They simply extend the partitioning scheme outward thusly:
So you can see that this disk got extended out to 8 partitions (sda 7+8), with 1,2,3,5,6 and 7at 500GB and the 8at around 300GB.
I understand what Dish has done, but at this point I haven't the faintest clue as to why this method was selected.
Please bear with me, I'll probably be editing this several times to get the spacing just so in the code sections.

Priority issues!!
I thought I would come here and find lots of complaints about the update to the dish anywhere mobile app, but am not seeing any. It used to look just like the desktop webpage. Now you can no longer filter by sports channels or movie channels. Plus that they made it look like a big button telephone and you see fewer channels in the screen which requires more scrolling. Yes I realize you can look at sports then select which sport you want to look at, I just liked being able to see all sporting events in the guide with all other channels being filtered out. Am I alone in the wilderness on this?

Apple has finally released their Apple TV 4K with built-in Siri and a microphone so it can respond to your queries even if you don't have the remote. It also increases in price, to $299. I had been planning on updating my current Apple TV 4K streamers, but that's $600 for the two of them, and that's a pass at this point.
At $299, it had better come with 256 GB of Storage, Gigabit (or better) Ethernet, the latest HDMI tech and standards, and one year of free Apple One. But it probably won't…

. apple's been making money off of software and not hardware for a while
they all do that anyways.. ever notice your cell phone slows down when you come up for an upgrade..

You should have looked in the APP STORE instead.

Several Dish offers showed up today in my account. Once you choose one the rest are removed. Offers were Showtime, Starz, AMC and others.

Not for me, mines has no mention of how long aka the offer period and the Terms and conditions the $0.00 is good for. All I see is one can lose $5.00 if you decide to remove it before day 31 after you add it to the account.
You have a different offer that is free for a shorter timeframe which is different than the one that I and bnewt saw without defining the promotion period as I sent the question to DISH Care via Facebook Messenger and this is the response I got back 20 minutes ago.

But.....if you like Tulsa King....looks like you would probably like this as well. I don't mind spin-offs as long as they don't involve a sassy niece who moves from the big cityAnother Tulsa King spin off.
Anyone else watch this show? Any guesses as to what was in the box Gibbs gave to Abby that was on her desk? It look liked it was glowing.
I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

Tony as the director.
Would you rather have LaRoche ???Tony as the director.
No. Bring in someone new.
Tony is not serious enough for me. Parker is too close to the team and Tim is too young to take over IMO.
I don't think Tim and Tony are that far apart in Age ...No. Bring in someone new.
Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)
Tony has changed, he's been running his Security Business ... I'm sure he has grown up.
Give it time ... your judging the New Tony from the old Tony.
It sounds like Tim won't be around the Team much longer either.

Might be worth a watch when it comes out. Looks like typical big corp against the little guy movie BUT....there is a reason this plot type is so oft repeated, it draws audiences.
