[j-nsp] Sandisk Extreme III 1G CF card compatibility

[Dave Diller]

This is an FYI, and a separate issue form Pekka's discovery that these  
faster cards can hog CPU when being written.

It turns out that some SanDisk Extreme III 1G cards are Juniper  
friendly, and others are not.  We purchased three at the same time  
from the same CompUSA.  Of the three, two do not work and the third  
one is fine. The symptom is that the non-functional ones time out and  
you can't install anything on them (but 6509's are fine with them, so  
they'll be redeployed there ;-):

and it keeps trying and timing out for 20 minutes or so.



This one:
ad0: 977MB <SanDisk SDCFX-1024 HDX 4.03> at ata0-master PIO4
is the one that works.  The card has ID BB061004765B printed on the  
edge.

The two that do not have code BB070504765B, and they ID on boot as
ad0: 977MB <SanDisk SDCFX3-1024 HDX 4.08> at ata0-master PIO4

The difference in the beginning portion of the printed code looks like  
a date code.  The 4.03 version looks like late 2006, and the 4.08  
early 2007.  So old stock seems fine; later ones do not.

FWIW, the older one that works has "ESP technology" printed UNDER the  
1.0GB part of the label, while the newer ones have the ESP logo to the  
LEFT of the 1.0GB.
