[c-nsp] CF format problems on 6500/7600 SUP720-3BXL

[john douglas]

hi all,

firstly i've read the threads about monlib etc, i tend to make it
standard practice to format the flash card in whatever chassis it is
currently in before use, however in this case, i cant even format the
flash cards. we are talking about genuine sandisk 1GB which seem to
work ok elsewhere but in the 6500 & 7600 SUP720-3BXL based platforms
everything appears fine until you go to format the card and then you
get this

Router#format disk1:

Format operation may take a while. Continue? [confirm]

Format operation will destroy all data in "disk1:".  Continue? [confirm]

%Error formatting disk1 (Format failure - Drive Communication)



and then the CF card promptly disappears

Router#dir disk1:

%Error opening disk1:/ (No such device)

Router#sh plat hard cap | i disk

         1  SP  disk0:                       128151552      78741504       61%



i have tried formatting these CF cards on other routers eg 7301, 1841,
bring them over to the SUP720, they look fine, but the moment you go
to re-format - splat.

i have tried formatting these CF cards on a PC using a CF card reader,
again they look fine, but again splat.

now, what is REALLY wierd

i format these CF card on a Canon EOS 400D digital SLR and they work
just fine in the SUP720
