flash_erase errors with PP V3 Pro (3 replies)

Hi,

I'm trying to use a PogoPlug V3 Pro as a wireless squeezebox player, and I ran into an error from flash_erase while following Qnology (GreyMan?)'s instructions for V3 Oxnas at this link:

MTD Erase failure: Input/output error

I can still ssh into the box using 'ceadmin', and I'm looking for assistance with deciding what I should do next. It looks like the uboot environment goes at the location that I had trouble erasing.

~ # /tmp/fw_printenv 
Too few good blocks within range
~ #

Should I try erasing again, programing the env, and seeing what it looks like with fw_printenv? Or can I locate the env at a different address?
