IanJackson Posted September 19, 2009 Share Posted September 19, 2009 Although SSDs are superb compared to hard disks, the inevitable performance degradation does become annoying. Unfortunately a lot of SSDs - including my Corsair P256 - are not supported by HDDErase. I've tried versions 3.1, 3.3, and 4.0 on a number of motherboards with varying chipsets in IDE compatibility modes but none of them work - they just report that the drive is in a "frozen state". After a morning of fiddling about, I've worked out a way of performing the required secure erase function another way. The reason the SSDs are not compatible with HDDErase is due to a BIOS lockout. Whilst many claim that putting the controller into compatibility mode fixes this, it certainly doesn’t on my Asus X58. You therefore need to use a different utility that can read disks from another sort of controller- namely USB. First of all you're going to need a number of items; 1. A GParted Live.iso http://sourceforge.net/projects/gparted/files/gparted-live-stable/ 2. A blank CD 3. A USB-to-SATA adaptor or enclosure, any should do. 4. A USB cable First use your favourite disk imaging tool to burn the .iso of GParted to disk. Next, shut down and disconnect all of your hard disks from your computer. Remove your SSD and install it into your USB enclosure. Start the machine back up and boot from your GParted Live disk. A number of prompts will pop up during the boot sequence, in each case just hit enter until you reach the main interface screen. A window should pop up displaying your SSD’s partitions. Right click on any partitions and delete them. In the top right hand corner of this window is the name of your SSD. Remember this name! http://img186.imageshack.us/img186/618/gparted.jpg Next, double click on terminal and type the following; hdparm --security-erase NULL /dev/hda Where /dev/hda is the name of the disk you remembered earlier. The drive will now be secure erased and all data will be deleted. The disk will also be restored to factory performance. My SSD had degraded to below 120MB/s in HDTune Pro. After performing this is was back to its 200MB/s+ best. Hope others find this useful! Link to comment Share on other sites More sharing options...
