Il mio laptop sembra danneggiare i dispositivi USB, cosa posso fare al riguardo?

Almeno tre dispositivi di archiviazione di massa USB sono diventati inutilizzabili dopo essere stati collegati alla stessa macchina. Non ho verificato tutte le sue porte USB, ma succede con più di una.

Uno dei dispositivi era un disco rigido Seagate, un altro era un nuovo lettore MP3 (sicuramente economico) e anche un paio di chiavette USB.

Ecco dmesg dall'errore più recente:

Ho funzionato di nuovo

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>

Il fattore comune è la macchina e Alienware M17x R4 che esegue Ubuntu. I fallimenti sembrano accadere durante le scritture, non le letture. Mi chiedo se le porte USB stiano erogando troppa potenza o qualcosa del genere. La macchina ha circa 5 anni, generalmente non funziona a caldo e non posso attribuire altri comportamenti scorretti a problemi hardware.

Come posso indagare per scoprire se c'è un errore elettronico o software che danneggia questi dispositivi e c'è qualcosa che posso fare nel software per risolverlo?
