I have a CS1000 chasis on 4.5W and receive EDD007 when doing a data dump and a BKO to a PCMCIA. I tried rebooting and performing an EDD CLR. Nortel's knowledge Base mentions a DAT and SWP commands in load 43 to switch the main and .bak data bases. Perhaps then a BKO would work. I believe I have a corrupt C drive, but I have no current backup. Any ideas????
