1811 lost space on the flash. CF corrupted?

[MaximBudyonny]

Hello.

I want to upgrade IOS on 1811 from 12.4(11)T3 to 12.4(15)T16.

As a standard CF size in the 1811 is 32 M, so I have to free some space.

Here the strange things starts.

dir issued on the router shows thet ther is no image on the flash!

dir

Directory of flash:/

No files in directory

31940608 bytes total (12771328 bytes free)

sh ver shows that

uptime is 19 weeks, 2 days, 9 hours, 22 minutes

System returned to ROM by power-on

System restarted at 15:21:30 EEST Tue Jul 26 2011

System image file is "flash:c181x-advipservicesk9-mz.124-11.T3.bin"

The other strange thing is that some space is allocated for something!

(flash size) 3194060 - 12771328 (free) = 19169280 (space allocated to ???)

Just now router is running  IOS c181x-advipservicesk9-mz.124-11.T3.bin

The size of this IOS  is 19 155 816, that is approximately equal to the size that allocated to something invisible.

fsck flash and format flash doesn't help.

Bug Toolkit doesn't show any bugs similar to my issue.

How can I free space on the flash?

Don't know if this is going to help, but try "squeeze".

[MaximBudyonny]

Thank you for reply, but 1811 has class C file system. squeeze is not supported on class C.

Then you got a faulty CF.  You can replace it the right way or the "that's about right" way.

And if you are going to buy a new flash card, you may as well get a 128Mb one, so you don't have to run out of space anytime soon.
