cisco 3750-Flash not detected

[youness10]

Hello ;

I have a 3750G switch that it has flash not detected on Roman mode, I try flash_init and dir flash: but no look as below :

switch: flash_init
Initializing Flash...
...The flash is already initialized.

switch: dir

List of filesystems currently registered:

bs[0]: (read-only)
xmodem[3]: (read-only)
null[4]: (read-write)

Can anyone help me fix that issue .

The syntax is incorrect.  Try "dir flash:".

I already do it, but I get
switch: dir flash:
unable to stat flash:/: no such device

Ok, console into the switch and reboot the switch.
Post the entire bootup process.

Ok, last try ...
1. Reboot the appliance; and
2. Try the command again "dir flash:".
If the problem still persist, try the command "format flash:".
And when it says "are you sure", enter "y".

As mentioned by Leo, if you want to look at the files in the flash, you need to specify the flash: as part of the dir command, ie dir flash:

See https://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/41845-192.html for some examples.
