I have been hit by Crytobit v2. At this time there is no known remedy. I have a Patriot Pyro SE 120GB that was my C drive. Fortunately I have a backup HDD. I'm going to install the backup as the new C drive.

In the past I have used Acronis to WIPE HDDs. I want to do the same to the SSD. My concern is I want to make sure there is no way I will infect my backup drive when I TRIM the SSD. I don't want to give up and toss the SSD.

 

Thanks for your help - Mystified

You can use a bootable linux disk and the hdparm command to use the internal ATA erase command of the SSD. It also has Secure Erase which does the same thing if I remember correctly. The last free version of Parted Magic is here. I don't know if the free version is compatible with SSD. The latest is a $5 download.

Edit: I don't believe Trim wipes a drive.

 

Another link that may help
