(Note that this is the best effort option, so it will silently ignore it if the hardware doesn't support it.) So in most cases you can simply ignore the problem, install Linux, and the installation process will do all the cleanup you need. I note that mke2fs has the -E discard option that should trim the partition when creating the file system, which is enabled by default. There are many options for this, including those mentioned already. The only concern is that the drive should know that the space used previously by Windows is now free, to optimize SSD use. Though if you just want to wipe the drive to install Linux (as per the question), you don't need to do a full wipe. (I was checking on a Dell Precision 5510 laptop from 2017.) This is probably a widely used option in corporate environments, so many vendors probably include it now. By default, Smartctl is included in the default repository of all major Linux distributions. A root password is configured on the server. A server or Desktop running Linux operating system.

On a laptop I just checked, there's an option to do a secure erase of all attached media on the next boot. In this post, we will show you how to check SSD and HDD health on Linux. How can I make all blocks appear as empty using TRIM?Ĭheck to see if the BIOS on the computer supports this. Option: an LBA starting address, a colon, and a sector count, This optionĮxpects one or more sector range pairs immediately after the Scheduling for wear-leveling of the flash media. Use by the firmware's garbage collection mechanism, to improve This will run a short test that takes approximately 2 minutes. sudo apt install smartmontools Step 2: Run the command sudo smartctl -t short -a /dev/sdX (in place of sdX, use the name of your SSD). This makes those sectors available for immediate Step 1: Install the smartmontools package with the command sudo apt install smartmontools. smartctl -a /dev/sda grep MediaWearoutIndicator. For 100 means your ssd has 100 life, the lower number means less life left. The MediaWearoutIndicator is what you are looking for. USE THIS OPTION!! Tells the drive firmware to discard unneededĭata sectors, destroying any data that may have been present For Ubuntu, Mint, or Debian based distributions.

From its manual page: -trim-sector-rangesįor Solid State Drives (SSDs).
Hdparm seems to be the program to do it, but I'm not sure if it clears the disk OR cleans empty blocks. I've seen the answer How to enable TRIM, but it looks like it's suited for clearing empty blocks, not wiping the disk. I believe that dd if=/dev/zero of=/dev/sda just fills the blocks with zeroes and thereby taking another write (correct me if I'm wrong). It does not have to be a "secure wipe", I just need the empty the disk in the most healthy way. For testing purposes, my dealer put Windows on it, but I want to get rid of this and install Kubuntu on it. I've just received my new SSD since the old one died.
