IOS image couldn't be copied to any file system

Hi All,


I'm having issues dowloading an IOS from FTP server. Connectivity was already checked and verified.

See error below;

switch#copy tftp bootflash:
Address or name of remote host []?
Source filename []? out/cat4500e-entservicesk9-mz.122-53.SG4.bin
Destination filename [cat4500e-entservicesk9-mz.122-53.SG4.bin]?
Accessing tftp://
%Error opening tftp:// (No such device)

When I tried to save a text file to the bootflash, it won't save.

switch#copy run bootflash:config.txt
Destination filename [config.txt]?
%Error opening system:/running-config (No such device)

I can write on the nvram

Building configuration...
Compressed configuration from 39462 bytes to 13833 bytes[OK]

Can we concluded that my bootflash is corrupted?
