Not really. I doubt the person in the shop will care. Incidentally, I've discovered that you really don't want to buy flash devices from camera shops. It would seem that, like I guess might be the case with certain "audio CD" blanks you buy in stores, they don't seem to care about selling you a device with one or two known-bad sectors. You won't notice 512 bytes of lost data in many JPEG images (not that I am saying it's a good practice to have) but my Zaurus /did/ notice when I couldn't reflash it from a CF card with a fault somewhere around 8MB. After quite some time of screwing around with the filesystem by hand, I was able to ensure that something else was occupying the sector in question and eventually was able to reflash (all because it was a Sunday afternoon and we have silly Sunday trading laws here). When I took the CF card back to the camera shop, I took the Zaurus and did a test on potential replacement cards while in the store - explaining that my PDA had a "CompactFlash tester" installed, or something like that. It's amazing what you can get away with - akin to spending an hour in the store when I got my replacement Powerbook after finding a single bad pixel, testing every unit to find one without any, just to be happy :-) Jon. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
