Can't erase SSD on T440p

Hello, I have a T440p. It has an SSD drive that it came with originally. Now I wish to secure erase it. I've tried with the ThinkPad Drive Erase Utility but when I try to boot with it I only get the following error message:

ERROR: This utility works for Disk Encryption Drive or Solid State Drive only.

 

I've confirmed that the SSD functions normally, so it's odd that the erase utility won't recognize it. The web page for the utility specifically says it supports T440p.

 

I've also tried with Parted Magic, but it only says that the drive is "unsupported".

 

Does anyone have any advice on what to do here?

The utility resets the encryption key.  It doesn't write zeros to every sector.  I use Active Kill Disk (free version)

Re: Can't erase SSD on T440p

Thanks for your reply. I believe simply "zeroing" out an SSD using a classic wiping software is not recommended, as an SSD stores/manages data in a different way than a traditional HDD, defeating the purpose of attemting to "zero" it out manually.

 

So I was looking for a way to use the built-in wiping instructions (e.g. via ATA instructions) or otherwise wipe it out in an SSD compliant way. As mentioned I tried Parted Magic, but it didn't seem to support my SSD drive for some reason.

 

Using the erase utility would still be acceptable I suppose even if it just reset the encryption key, because then the data would be deleted permanently by any practical means. But the problem is it doesn't seem to recognize my SDD as an SDD. Some pointers on how to successfully use this utility or otherwise wiping my SSD in an SSD compliant way would still be appreciated.

From your original post, it looks to me like the drive isn't encrypted so there is no encryption key to reset.  That's why I suggested writing zeros.
