I faced a similar problem with pix sometime back. When looking out for solutions, I read somewhere that erase flash doesnt completely remove ios from flash but compress & stores it. Probably thats what the delta content represents in your output. have u tried delete command. I dnt exactly remember, whether its delete or something else to completely remove ios from flash. Searching..... will post back.
If the router has a bad Flash, it will not be able to download the Cisco IOS software image. If you issue the show flash command, it will not be able to recognize the Flash. Below is an example of a bad Flash:
8192K bytes of processor board System flash (Unknown flash)
Directory of flash:/
%Error opening flash:/ (Invalid argument)
No space information availableIf the Flash is bad, it should be replaced.
I ran into this when trying to take my PIX 525 from 6.3(5) to 8.0. Wasn't making sense because the device has the required 16MB flash, but it wasn't working. During the intial reboot in the upgrade process the new code rewrites how it addresses and uses flash and allows you to use a flash amounts greater than 8MB, but before that on 6.3(5) I believe you can only use 8MB chunks.
You might check to make sure you're using PIX code 7.0/8.0 code and not ASA 7.0/8.0, which was my issue. I know better but for some reason it wasn't clicking that the code would be specific to the firewall hardware. Also the PIX code stays under 8MB while the ASA includes more bloat that gets it up into the 14MB.
You'd think if you're using the wrong code that it would tell you, but it does not, at least on 6.3(5). It simply says insufficient memory. However on newer releases it does state image not valid for platform.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
