I want to be sure that some HDDs that i don’t quite 100% trust dont fuck up my data over time. Something that can check for files that should be unchanged but have changed anyways would be cool.
Most data isn’t changed often. If i were running a linux-based OS, i would just go for BTRFS or OpenZFS, but on windows that won’t work.
The tool does not have to be super sophisticated. Im thinking about writing something like this myself:
- make a checksum for each file and save it in a database, together with the files last modified date
- periodically go through all files (maybe once a month). Recalculate the files checksum. If the file has the same last changed timestamp as in the DB, compare checksums and alert me if something is off. Otherwise update the checksum.
