I am attempting to upgrade the flash in a Cisco 2621 router from 8M to 16M. The router appears unable to write to the flash, and I've reseated it and tried different sticks of flash. It recognizes it and reports the correct capacity. I've attempted the procedure below with 2 sticks of flash, all with the same results. What, if anything, am I doing wrong here?

Have you tried to Fsck the flash?

If so; what was the result.

Unfortunately, the only IOS's I am able to boot from at this time (32MB DRAM) do not have fsck (or format, for that matter), and from a quick search through Cisco's feature navigator, I come up with no IOS that supports this feature for the 2621.

It would appear that I just had a string of bad flash sticks. What luck :(
