Received a batch used of Toshiba SSDs from an eBay auction. So let's see what's on them... 

itops@warthog-1:~$ time sudo strings -a /dev/sda 

real	0m1.396s
user	0m0.007s
sys	0m0.008s
itops@warthog-1:~$

So we read half a Tbyte in 1.4 seconds? That seems a bit ... beyond the capabilities of current storage technology. Let's see what the kernel has to say about this...

See all those Add. Sense: Security conflict in translated device notes in there? That seems to indicate a password-locked ATA device. I'm sure there are lots of docs about this on the interwebs, but let's just skip all that and get to a solution, shall we?

First, make sure there is nothing actually using that disk. lsblk is a decent starting place for that: 

itops@warthog-1:~$ lsblk /dev/sda
NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda    8:0    0 476.9G  0 disk 
itops@warthog-1:~$

Nothing with /dev/sda as a parent. Maybe fuser, too? 

itops@warthog-1:~$ sudo fuser -v /dev/sda
itops@warthog-1:~$

That looks good. More investigations, using hdparm this time: 

itops@warthog-1:~$ sudo hdparm -I /dev/sda

/dev/sda:
