Cisco ASA 5525-X internal flash memory issue

[Samir Aliyev]

Salam Aleykum.

We have flash memory issue in ASA 5525-X.

it works from time to time , it has unstable hardware.

During working with flash (for example: write, delete, copy, etc.), we face the following error in Cisco ASA CLI. 

%Error opening disk0:/.private/startup-config (Read-only file system)

Error executing command

[FAILED]

fsck  and  formatting the flash did not help. 

We cannot even find the flash memory itself in ASA equipment itself. )

in next-generation firewalls cisco calls it - as internal usb or internal flash memory.

In an old firewalls it was easy to replace flash :) . Why cisco did such thing in next-generation firewalls?! 

Waiting your advice, and help.

Thanks in advance.

What command did you use to try to format the flash?

[Samir Aliyev]

format flash:     or   erase flash:

[nspasov]

Yikes! So you have tried both :( Sounds like you need to open a case with Cisco TAC. Please let us know of the outcome!

I have no permission to Cisco TAC.

But I will try Cisco Partner Help.  

I will inform you InwaALLAH. 

Can I use external Usb  as system flash?
