| License | The single-site license permits use on one computer at a time, while a company/business license permits unlimited compatible company computers and employees. | nvm is distributed under the MIT License, permitting use, modification, distribution and sale subject to retaining notices. |
| Purpose | DRevitalize diagnoses and repairs physically damaged magnetic media, including hard drives and some floppy drives. | nvm lets users install and use different Node.js versions from the command line. |
| Security | The maker says installers and executables are checked with several anti-spyware and antivirus engines. | The GitHub repository links to a security policy, but the README does not state a security certification or compliance standard. |
| Support | The site provides support through [email protected]. | The project states that only the latest nvm version is supported. |
| What it does | DRevitalize diagnoses and attempts to repair physical bad sectors on hard drives and, to a lesser extent, floppy drives. | nvm is a per-user, per-shell command-line manager for installing and using multiple Node.js versions. |
| Windows support | DRevitalize is designed to run on Windows 10; version 4.0 requires at least Windows Vista and .NET Framework 4.6. | The original project targets Unix-like systems and Windows WSL; native Windows users are directed to the separate nvm-windows project. |

In their own words
DRevitalize
DRevitalize is Windows software for diagnosing and attempting to repair physical damage on magnetic media, including hard drives and some floppy drives. It works around damaged areas by generating sequences of high and low signals intended to repair bad sectors. The listed current version is 4.10 for Windows and UEFI, and public demo downloads are available for Windows, UEFI, and DOS. Modes include scan-only checks and scan-and-repair read or write tests. Other functions include SMART analysis, raw-data copying, secure erase, Format Unit, ATA security operations, and Device Configuration Overlay controls. The software is intended for minor surface damage, typically a few bad sectors, rather than hundreds or thousands. It can inspect and modify SSD parameters, but cannot truly repair a defective SSD sector; it may reallocate that sector. UEFI use requires a 64-bit system and recent BIOS. Windows support information says the product is designed for Windows 10, while version 4.0 requires at least Windows Vista and .NET Framework 4.6. License ordering is no longer available and the project is on hold.
nvm
nvm is a free, MIT-licensed command-line tool for installing and managing Node.js versions. It is designed for installation per user and invocation per shell, and works in POSIX-compliant shells including sh, dash, ksh, zsh, and bash. Users can install specific versions, switch between them, set aliases such as a default, and use LTS aliases and commands to select long-term support versions. A project can specify its Node.js version in an.nvmrc file; documented shell snippets can support automatic switching. During installation, nvm can reinstall global npm packages from another installed Node.js version. With the --offline flag, it can install a version that was previously downloaded or cached without network access. The project documents use in Docker, including an example for CI/CD jobs. On Windows, nvm can work through WSL and may work with Git Bash or Cygwin depending on the environment. Fish shell is not supported, and the project points users to community alternatives. The project states that only the latest nvm version is supported.
