However, even SSD Trim doesn’t securely delete data. Because the SSD hardware controller does the
job independently, you cannot say for sure when it actually trims all blocks. Furthermore, SSD drives use
some unallocated space as a buffer during the wear leveling to keep data records there.
Only the so called "Secure Erase" function can help you to irreversible and completely delete data from
SSD. Many SSD manufacturers include it into their hardware management tools. Our Linux-based
recovery environment also contains this capability. So if you need a guaranteed permanent deletion of
data from your SSD or NVME SSD drive, please use the secure erase.
The list of supported wiping algorithms may vary for your product.
The "trim" command works for individual volumes, entire drives, and remnants of deleted files.
To create a new wiping algorithm, define up to four wiping patterns, number of passes for each wiping
pattern and for the group of patterns. The Mask spinner control allows you to set a hexadecimal
character value ("0" by default). The available range is from "0" to "FF". You can also choose whether to
carry out residual data verification or not specifying the percentage of sectors to check.
- Mark the Set wipe stamp option to add information on the used wipe program, algorithm, device
serial number, and other properties to the MBR (Master Boot Record) of the wiped storage device to
get notified during the boot phase how and when the storage has been wiped. Please note this option
is available when wiping entire disks only.
