Sta znam polovni diskovi pogotovo nvme , kazu da je njima lagano softverom resetovati podatke da na kraju svi budu kao novi, bukvalno upises sta zelis.

Ovaj nema ni godinu i po dana. Ali, sve je moguće.

Pa citao sam po forumima da ima softver gde bukvalno svakom nvme disku uneses koje god zelis podatke da prikaze i to radi bez problema i tvrde da je to dosta teze uraditi klasicnom HDD ili SSD, a da je za nvme diskove to bas lagano.

Changing what an NVMe drive reports about its health, reads, and writes to utilities like Hard Disk Sentinel or smartmontools is not straightforward and is generally not supported on consumer hardware. Here’s a detailed breakdown based on current knowledge and your query:

How NVMe Drives Report Health and Usage

• NVMe drives report health, reads, and writes via standardized log pages and SMART attributes defined by the NVMe specification. Utilities like Hard Disk Sentinel and smartmontools simply read and display this data; they do not generate or modify it themselves

• .
• The reported values (such as total bytes written, available spare, percentage used, etc.) are maintained by the drive’s firmware and are, in principle, immutable from the host side for security and integrity reasons

• .

Is It Easier to Manipulate NVMe SMART Data Than SATA?

• There is a perception that NVMe drives are "easier" to manipulate because their firmware and reporting mechanisms are more modern and, in some cases, more accessible for research or attack purposes
• .
• However, on standard consumer hardware, there is no supported or documented method to alter the SMART data (such as total writes or health percentage) reported by the drive. The values are stored and updated internally by the drive’s controller and firmware, not by the operating system or user-level software

• .
• Advanced attacks or modifications—such as those described in academic research—require custom firmware or a specially crafted NVMe device (e.g., using an FPGA or a research platform) to spoof or alter reported values
• . This is not possible with off-the-shelf drives using standard commands or utilities.

What About Firmware Updates or Vendor Tools?

• Firmware updates can sometimes reset or change how certain attributes are reported, but this is at the discretion of the manufacturer and not accessible to end users for arbitrary modification
• .
• Some enterprise or datacenter SSDs may support vendor-specific commands for resetting certain statistics, but this is rare and not available on consumer NVMe drives
• .

Security Research and Spoofing

• Security researchers have demonstrated that a malicious or custom NVMe device can be programmed to spoof SMART data, health, and usage statistics, effectively reporting any values the attacker wishes
• . However, this requires building or modifying the drive’s firmware or using a programmable research platform—not something achievable on a locked, commercial drive.
• In summary: spoofing or changing NVMe-reported health and usage data is only possible with custom firmware or hardware, not through standard utilities or commands on consumer drives

.
Conclusion

• You cannot change what an NVMe drive reports about health, reads, or writes to utilities like Hard Disk Sentinel on consumer hardware using standard methods.
• Any manipulation of these values requires custom firmware or a research platform, which is not practical or possible for standard users

• .
• The perception that it is "easier" than with SATA SSDs or HDDs likely stems from research environments, not real-world consumer scenarios
• .

If you need to reset or spoof these statistics for legitimate testing or research, you would need to use a programmable NVMe device or develop/flash custom firmware—something not feasible on regular commercial drives.
