Unintentionally powered off external HDD when moving some files with the move command. Now the move target folder is "The file or Directory is corrupted and unreadable".
chkdsk E: /f /r /x
Failed during the process ("An unspecified error occurred").
NTFS is said to can tolerate power outage with something like transaction logs, then how can this happen? The external HDD is NTFS and set to "fast remove" mode too.
(1) Can HDD tracks be damaged in a hardware way during power outage? Won't The magnetic head be lifted when the HDD detects an under voltage to protect the tracks?
(2) If tracks are not damaged, then the maximum damage will be some inconsistent written file contents and directory entries. But NTFS as a robust FS with logs, why can't even chkdsk recover the problem and the whole folder is just unreadable and not fixable? Doesn't NTFS have backup mechanism for the directory entries?
updated: Although chkdsk doesn't work, I connected the external HDD to PC again and a message box asked whether to repair the problem and I choosed repair and the unaccessible folder disappear and appears in the folder one level up, all contents are there. This is how the problem is solved, but not an answer to the question (1)(2).
