HOT 284: Understanding How to Recover Deleted Files - Can You Recover Deleted Files?
Summary
Micah Sargent explains that while deleted files on traditional hard drives remain recoverable, modern SSDs use the TRIM command to physically erase data within minutes. He uses a library analogy to clarify how file systems mark space as available and why recovery tools are largely ineffective for internal SSDs. The episode advises listeners to check cloud backups and trash folders first, noting that recovery software is best reserved for external drives and memory cards.
