Cisco Switches :: Cannot Make Any Changes To SF-302-08MP

This is the third series 300 switch I've configured, but have not run across this issue before.  I've attached to the switch via the console port and even tried with the web interface but get the same results.  Upon booting the switch asks for the default user ID and password, then it prompts to change the password.  I do this and then go to configure the device with the new IP address, add a new user ID and password and VLAN.  All changes seem to save as I get no errors.  However, when the device is rebooted, all changes are lost.  I've even went so far as to delete the startup-config file but still no luck.  Version information is as follows:
 
SW Version:            1.0.0.27 (Date:  28-Apr-2010, Time:  13:33:55)       
Boot Version:          1.0.0.4 (Date:  08-Apr-2010, Time:  16:37:57)        
 HW Version:            V01
