Eu tive pelo menos três dispositivos de armazenamento em massa USB inutilizáveis depois de serem conectados à mesma máquina. Eu não verifiquei todas as suas portas USB, mas isso acontece com mais de uma delas.
Um dos dispositivos era um disco rígido da Seagate, outro era um novo (reconhecidamente barato) MP3 player e alguns pen drives também.
Aqui está o dmesg da falha mais recente:

Ran fsck novamente
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdc
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
O fator comum é a máquina, e o Alienware M17x R4 rodando o Ubuntu. As falhas parecem acontecer durante as gravações, não nas leituras. Eu me pergunto se as portas USB estão gastando muita energia ou algo assim. A máquina tem cerca de 5 anos, geralmente não funciona muito bem e eu não posso atribuir nenhum outro mau comportamento a problemas de hardware.
Como posso investigar para descobrir se há uma falha eletrônica ou de software danificando esses dispositivos, e há algo que eu possa fazer no software para corrigi-lo?
