I was doing a change in m ASA5505 today, but when I was trying to save it to memory, I got the message
%Error opening disk0:/.private/startup-config (Read-only file system)
Error executing command
What can I do to resolve this? I have tried reloading the ASA, but that did not help. I can not do changes to the filesystem (copy, delete) either.
ASA-5505(config)# fsck disk0:
It looks as if flash memory is corrupted. Command mentioned above does a file system check and attempts to fix corruptions.
