Run HDDErase and do a secure erase.
Formatting your drive now actually does something. You no longer have to boot to DOS and secure erase your SSD before installing Windows, just quick format the partition before installing Windows 7.
can anyone confirm this works on a used drive before installing windows?
I got a X25-M myself (80gig) and decided to format since TRIM was now supported.
Everything works fine with just a quick format, i actually got a 7.8 at WEI and had 7.7 before
So it should work OK
