EXTERNAL 2TB USB DISK that casually goes nuts
I have this 2TB hard disk, fresh new, that goes nuts when connected to a debian box.
I use it to backup stuff from my laptop, from another computer, but sometimes when I connect it to some Linux Box, the entire partition goes wiped out. I sometimes recover it using Testdisk, sometimes I must rely on my second backup copy (I have three of them 
) but this time I was able to pinpoint WHAT computer caused this trouble. So I decided to investigate this shit.
Computers involved: Gemini (my laptop, IBM Thinkpad), Norad (a very nice and big computer), Cosmos (a little one).
NOTE: This is *NOT* a problem of the USB box / interface: it appears on different computers, using different USB box / interfaces, and also connecting the hard disk directly on SATA connectors.

EXTERNAL 2TB USB DISK that casually goes nuts
- Hard disk da 2TB
- Clean disk, connected to Norad, Linux Mint 17 Mate edition
- I create a brand new fresh ext4 partition using gparted
- What NORAD see mounting this disk
- I copy some files/dir on it
- umount and move the udb disk on Gemini
- This is what Gemini see
- LET'S GO BACK on NORAD to see if everything's ok
- Let's move on COSMOS
- What COSMOS see
- CFDISK gives ERROR!!!
- Since now, the entire HD is CRAP.
- What COSMOS see NOW about it
- Let's get back the USB disk on my GEMINI laptop
- What GEMINI see of this disk now
- Let's try testdisk on it
- TEST: save partition data and compare it before/after the problem
- TRYING with a GPT label / partitioning scheme
- udisks doing shit?
- THE SOLUTION
- Some references

I create a brand new fresh ext4 partition using gparted
As standard I choose Align to MiB.
What NORAD see mounting this disk
It's automagically mounted at connection.

No desktop icon, I will try a manual mount:
rover asbesto # mount /dev/sdb1 /mnt
mount: you must specify the filesystem type
rover asbesto # mount /dev/sdb1 /mnt -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

NOTHING TO DO.
With gparted, I delete and create again the same unformatted partition
NOTHING TO DO.
Files are still there, testdisk can read them all.

Got really PISSED OF pressing Y forever, I try fsck.ext4 -y
ULTRA PISSED OFF of waiting forever, CTRL-C AND F%CK 1T.
TEST: save partition data and compare it before/after the problem
So I used
sfdisk -d /dev/sdb >filename
to restore eventually with
sfdisk /dev/sdb <filename
but they seem exactly the same.
Working hd:
# partition table of /dev/sdb unit: sectors /dev/sdb1 : start= 2048, size=3907026944, Id=83 /dev/sdb2 : start= 0, size= 0, Id= 0 /dev/sdb3 : start= 0, size= 0, Id= 0 /dev/sdb4 : start= 0, size= 0, Id= 0 partizionebiterone (END)

TRYING with a GPT label / partitioning scheme
Used parted manually to create GPT label, partition etc.
SAME PROBLEM.
udisks doing shit?
Nope. Killed udisks daemon, mounted / unmounted manually, only "rw" as mount option, same prolem.
THE SOLUTION
I dist-upgraded debian squeeze to debian wheezy and the problem DISAPPEARED.
It seem related to kernel 2.6.32-5-686...
I HATE DEBIAN. Why? Because there's no kernel update for squeezy. And yes, I had backports enabled, but apt-get update && apt-get upgrade installed nothing.
