Unable to write to flash

[Marius Gunnerud]

My client has had to replace their ASA 5510.  Upon importing the image to the brand new ASA they are unable to write to the flash.

They have run fcsk disk0: to no avail.

show file system show 0 and 0 for Flash size and Free space on disk0.

Is there anything that can be done, short of formating flash and trying to reinstall the image?  I have asked them to reload the ASA but they are reluctant to do so as they don't want the site to lose connectivity.

Thanks

no haven't formatted it.  I am wondering if there is anything we can try before resorting to formating?  As you can see below, I am bit curious why size and free are showing up as 0.

ASA#   sh file system

File Systems:

    Size(b)     Free(b)      Type  Flags  Prefixes

* 0           0           disk      rw      disk0: flash:

          -           -  disk      rw      disk1:

          -           -  network   rw      tftp:

          -           -  opaque    rw      system:

          -           -  network   ro      http:

          -           -  network   ro      https:

          -           -  network   rw      ftp:

          -           -  network   rw      smb:

When the format on the Flash is lost, the size will be read as 0 as it cannot read the spaces free or taken. That wont cause a thing and it is the most common procedure when we get cases like this.

So formating the flash is the only way forward?

[Maykol Rojas]

From this point forward. Yes.
