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 ;-): =================== Bootstrap installer starting =================== Initialized the environment Routing engine model is RE-4.0 Discovered that flash disk = ad0 , hard disk = ad1 ad0: TIMEOUT - READ_MUL retrying (2 retries left) LBA=79 ad0: TIMEOUT - READ_MUL retrying (1 retry left) LBA=79 ad0: TIMEOUT - READ_MUL retrying (0 retries left) LBA=79 WARNING: The installation will erase the contents of your disks.

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. -dd _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
