Cisco 2811 Flash card errors

[bryantsteve]

I have a C2811 router  with 12.4.15(t10) IOS at a remote site which failed to reboot after  a power cycling . I directed the on site tech to replace the flash card and reboot, and router recovered no problems.  I wanted to look at the "bad" card and requested the tech re insert this card.  As I executed a dir command, the router froze up and again had to be recovered using the spare flash card.  Any ideas about what could be causing this behavior? Thanks

From your description, a faulty flash card. Also check:
