You are not giving us much information here, what are you using to do the restore? What 4% are you talking about? I have over 25 SSDs and I restore them all the time with Acronis True Image using the clone setting. Or if I am just restoring them to the same drive I use the regular setting. Are you talking about over provisioning the SSD to 4%? When you initilize the SSD after using Parted Magic to do a secure erase or in your case Samsung has their own toolbox to erase the drive, okay back to initilizing, you go to Disc Management and initilize the SSD making it a Simple volume withe MBR and set the size of the partition to 1024. Then just put the drive in the computer you want to use it in and install the OS, its really much easier than it sounds.
