Flash showing negative memory size

Guys,

I am seeing flash memory showing negative memory.

sh flash

-#- --length-- -----date/time------ path

1 23347192 Mar 5 2012 17:04:04 +00:00 c1841-advipservicesk9-mz.124-25c.bin

2 720 Mar 6 2012 17:12:36 +00:00 vlan.dat

-301072384 bytes available (23461888 bytes used) >>>>>>>>>>>>

dir

Directory of flash:/

1 -rw- 23347192 Mar 5 2012 17:04:04 +00:00 c1841-advipservicesk9-mz.124-25c.bin

2 -rw- 720 Mar 6 2012 17:12:36 +00:00 vlan.dat

No space information available

I tried verifying IOS in the flash to check whether it is giving flash access error but it succeeded.

The router is up since more than 43 weeks but wanted to check if any one has seen this though reload shoudl resolve.

Best regards,

Santosh Pawar

That's got to be an IOS bug.

Did you upgrade the flash? I have seen it when I inserted like 2GB flash on an Cisco device and it did not know how to read 2GB flash and reported negative size.

There is no memory upgrade but seems to be IOS bug. I have planned router reload. I will keep you posted.

Not that it helps the discussion much but I am seeing the same problem on a 2811 with c2800nm-advipservicesk9-mz.124-25f.

I'm using a 4Gb flash card. To be fair support for the 2811 is only supposed to be for cards up to 256Mb.

It can read and boot from the card no problem, and I can copy files to it on a PC but my biggest problem is that I can't create a vLAN database on the device as it can't store it to flash because it considers it to be out of space.

I'm wondering if there's a way of formating large cards that I'm unaware of.

A 4Gb CF isn't the problem.  I'm using 2Gb CF and I don't see this problem.  I'm suspecting it's either an IOS bug
