[PROBLEM] which device is my USB HDD?

[mmontev]

I finally reinstalled xbian to de SD and now it seems to work.

In addition to what I posted here I found some really strange behaviour trough putty, and a kind of ghost mounted HDD on the /dev/mmcblk0p2 space. This leave no space on the SD partitions. Now I'm starting from zero, but with the drive already formatted to ext4.

And I can tell that is that I really don't think it has to do with the power supply. I use a big linear regulated (7805) PS that feeds the Pi on the GPIO power pins directly. I'm reading the voltage with a tester and it remains stable.

Here what I had on /media before reflash:
SAMSUNG-D680D17280D15997 ---> mistery
SamsungHDD-09d3dad4-9e14-400f-93d9-b6eaa8955392 --> the HDD name after ext4 formatting
usb0 --> alias of SAMSUNG-D680D17280D15997

I also found that SAMSUNG-D680D17280D15997 uses the space of /dev/mmcblk0p2. /dev/mmcblk0p2 is what remains of the SD card. It get full after some write tests supposed to be to the HDD. I deleted SAMSUNG-D680D17280D15997 which seemed to be a folder. Got some space on /dev/mmcblk0p2 gained and link /media/usb0 broken. but after reboot SAMSUNG-D680D17280D15997 and usb0 reappeared, with de SD full.

thanks and regard,
Diego

PS: must I modify the subject with "solved" o something?
