Xbox 360 RGH External USB HDD went south

[LerainL]

Hi there,

So i have a Xbox 360 RGH fully functioning with two external usb drives : 2 TB HDD and 500 GB SSD.
I have not used the console for about 4 months and today I've noticed that all of my games on Aurora Dashboard are grayed out.

I've connected to HDD/SSD to a computer and was expecting to see two new partitions to pop out.
Since i got nothing, opened a "EaseUS Partition Master" and got this picture:

This is not how i left the drives!

It seems they were completely re-partitioned by something that creates 259.79 GB partition, then another 259.79 GB partition and if there is still space on the drive, goes to 395.57 GB partition and then the rest of the disk is yet another one.

That's completely insane.

Luckily, I'm one of those persons who have a backup of a backup of a backup, so this time my 3-2-1 backup solution actually pays off. Otherwise, I would be running for the woods, screaming like crazy at the moment (or something).

Still, this is completely out of the question.

What in the seven hells messed up that badly with my partition? O.o

I'm asking it like that, since maybe you've seen this before or it's some kind of weird glitch with X360 or something.

I'm also scanning my drives with tools like "Partition Find and Mount Pro" just to see if there is any trace of the old partitions and the files.So far no luck, but it will take a while for the deep scan to finish.

P.S. I've checked the SMART status on the drives and they are all 100% Health

Have you used the FATXplorer XL Usb Drive patch / plugin perhaps? although that wouldn't be required for 2TB drives. That's the only thing I can really think of on the 360.

Drives generally don't partition themselves, so my only guess is the partition table somehow got corrupted.

I'm almost fully recovered from this. Just pushing the last 500 GB of games, so soon this will all be in the past.

However, I was not able to find any possible cause for this.

The only somewhat viable theory I have is that I was testing/playing a lot of indie games.
So maybe some of those messed up my drives, either because they were badly programmed or because that was the original intent of the game dev
Who knows.

I won't meddle much with unknown indie games, so I hope this won't happen again
