What cross-platform software for testing/checking a hard drive's condition/health would you recommend?
Also open to recommendations for similar diagnostic software for other data storage media like SSDs, flash drives, and SD cards. Just wanted to keep the title short and specific. If you're making recommendations for tools for the other types of media, please mention that.
i guess a fitting tool would clear and then re-write every sector of the DUT and inspect whether all went ok. an exhaustive test would make sure that each bit is at least once written in both states. i am not sure whether such tools exist apart from those proprietary solutions that happily sell you whatever you ask for without guarantee that your use is both reasonable and doable
