cannot delete file, Read-Only filesystem
i have a file a.txt i created on a external hdd. I wanted to delete it, but it complained that it is the "Read-Only filesystem",
So I tried "chomod 755 a.txt", it still complained the same thing.
I don't understand that i created the file, but cannot monify it?
is it has to do something with the external hhd has a ext_3 filesystem?
