I had genuine cause to run chkdsk from a command prompt yesterday (on my 8yr old Acer) because Acronis 2015 which I'm beta testing reported a problem imaging the drive (a bad sector).
I wondered... once chkdsk has run then the bad sector must be marked as non usable for future reference. Is that information held somewhere on the HDD (modifying the firmware) or is it somehow stored in within the OS.
If the former then its "permanent", if the latter then the information would be lost if for example you recovered to a disk image made prior to running chkdsk. Anyone any ideas ?
