3560G Flash Failure

[paxinos]

Greetings, 

Its looking like I have bad flash in an old 3560G.   'flash_init' fails as per below.   And when I try to format, it displays the question on y/n but doesn't give me an option to answer... it just exits...

Any hints on what I can do?   Is the flash user replaceable (I'm an EE)?  Or other options?

Thanks,

Pax.

ok, I got further...  one problem was user error - flag to send cr/lf was set... that was causing the apparent 'n' to the format command.

However I now get:

Post complete console output to understand the issue.

Thanks!

unfortunately 'fsck flash:' also fails with the same errors as seen below

here is the boot sequence

Can you post complete console logs when you do all the commands  to understand better.

I believe your Flash is Dead, do you have contract with Cisco so raise an TAC case for RMA.

If i were you i try other option - 

1. dir flash:

2. delete the exiting image ( that proves you able to delete )

3. From Xmodem you copy another version of image to Switch.

4. Boot with new image

5. once it boot with new image successfully,

6. change the boot varilable and boot againg and test.

post the outcome.

Sadly I think you are correct - dead flash.   And no contract.

switch: dir

               flash[0]: (read-write)

if i were you i replace with one of refubished kit available with cisco partner or ebay, since you do not have contract.
