[QUOTE="MacInWin, post: 1903892, member: 396914"] In the first post the OP said: What I suspect is that the hardware is just fine, in the sense that it communicates, but that the formatting/partitioning information has been scrambled by the improper ejection. In addition, in post 1 the things the OP tried didn't return errors that the drive wasn't there, but that drive was, in fact, there (tested ok for "diskutil verifyDisk disk2" but then failed for various format checks. This article from three years ago showed the same issue, and the problem seemed to be a corrupted superblock on the drive: [URL="https://apple.stackexchange.com/questions/344011/how-do-i-fix-hard-disk-error-69845-file-system-verify-or-repair-failed"]How do I fix hard disk "Error: -69845: File system verify or repair failed"[/URL] No fix was identified. One poster did suggest their own home-brew inspector, but that has it's own risks and may or may not run or work on newer versions of macOS. For [USER=397885]@vmvmvm[/USER], you mentioned Time Machine. Was this drive a Time Machine backup drive? Also, what Mac, and what version of macOS are you running? [/QUOTE]
