USB HDD ExFat partition became read only

Question

Iron

Again something happened to the USB HDD (Toshiba 320GB). It seems that during the recording on it, the ExFat section became read-only, i.e. files were not deleted from it and were not written, Windows offered error scanning, but it hung at 0%, while the first FAT32 partition worked fine.

upd: I transferred it to the computer (137GB and the suggestion to format it was after mounting it into a virtual machine with ubuntu), now it has returned to its initial state: read only.

Answer 1

Fixed by removing the flag that makes the ExFat partition read only (replaced 02 at offset 6a with 00), forum.ixbt.com/topic.cgi?id=11:43421-63#1880 . While it seems to be working.

Anyway, in this situation it is better to copy the data somewhere, format it and upload it back. The soul will be calmer.
