cisco catalyst 3640 read only file system

HI,

I have a customer switch that requires the configuration to be reset back to factory defaults but I'm getting a message,

Cisco Catalyst 3640 48 POE 4 x1G switch

File "flash:nvram_config" not deleted -- read only file system,

I've not come across this before so I would need a step by step support

output from switch

switch: dir flash:

Let the switch boot naturally

Let the switch boot naturally and then in enable mode, issue the command "wr erase" and this will factory default the appliance.

switch has booted up,

switch has booted up,

After powering up the cisco switch I'm faced with security banner and username to login,,

so pretty much in the same situation, is there a way to remove the flash files from read only to actually deleting them.

Thanks
