Overview
What Is NTLB - No Traces Left Behind?
NTLB is our own profile for drives that must come back as if they were never touched. It runs the same engine as DSP-DPDP India: the drive's own erase command where the drive supports it, careful handling of weak and bad areas, time limits on every read and write, and picking the drive up again if it drops off the bus.
It then writes zeroes over every sector from 0 to the last one and reads the whole drive back to check that each sector is zero. No wipe mark, header, footer, timestamp, software name or wipe detail is written to the drive. The certificate stays with you, not on the disk.
Best For
- Drives going back to a customer or a leasing company
- Refurbished drives sold on, where the buyer should find a blank disk
- Jobs where even a record of the wipe must not stay on the drive
Good To Know
- This is a Data Sanitization Pro profile. It is not a government standard.
- The drive is left empty and not initialised, so Windows asks to initialise it when it is next plugged in.
- A sector the drive refuses to the very end cannot be zeroed. The run then reports the drive as incomplete and lists those sectors.
Which Drives It Suits
SATA SSDs
The drive's own erase where it is offered, then zeroes and a full read back.
NVMe drives
NVMe Sanitize where supported, then zeroes over the whole namespace and a full read back.
USB and memory cards
Zeroes over the whole stick or card and a full read back. Nothing is written after.
How A NTLB Run Works
- 1IdentifyModel, serial, capacity and interface are read from the drive.
- 2SanitizeThe 1 pass sequence above runs across the full surface.
- 3VerifyThe standard requires a read back, so it always runs.
- 4CertifyA signed certificate records the device, method, result and operator.
NTLB Questions
How Is NTLB Different From DSP-DPDP India?
The engine is the same. NTLB always ends with every sector set to zero, reads the whole drive back to check it and writes nothing of its own on the drive. DSP-DPDP India leaves a small signed wipe mark on the drive.
Will I Still Get A Certificate?
Yes. The certificate and the log are produced on your computer and in your account. They are just not written to the drive.
Why Does Windows Ask To Initialise The Drive Afterwards?
Because the partition table is zeroed too. Nothing is created on the drive after the wipe.
