Cisco – Can’t Upload New ASA Image (I/O Error)

ciscocisco-asa

I'm trying to upgrade the code on a fresh, out of the box Cisco ASA 5510. However, whenever I transfer the code via TFTP I get the following message –

Writing file disk0:asa847-k8.bin...

%Error writing disk0:asa847-k8.bin (I/O error)

When I run the dir command –

Directory of disk0:/

No space information available

The No space information available is kind of concerning. Is it possible the disk is bad? Anyone experience this issue before? Any tips or troubleshooting steps to get around this?

Best Answer

As mentioned in the comments; The Cisco Support Forums suggest there might be something corrupt with disk0. Since this is a new setup, (optionally) backup the contents, and reformat:

ASA(config)#format disk0:
Format operation may take a while. Continue? [confirm] y 

Then upload your new image (e.g. TFTP):

ASA(config)#copy tftp disk0:
