I've never seen a hard drive lie to me before, didn't occur to me to check these numbers. > What does dmesg show about da0? da0 at umass-sim0 bus 0 target 0 lun 0 da0: <Generic STORAGE DEVICE 0.01> Removable Direct Access SCSI-0 device da0: 1.000MB/s transfers da0: 488MB (1000945 512 byte sectors: 64H 32S/T 488C) I get the same results when I try on a separate machine. I also get the same results when I use a second identical flash card. Any suggestions or pointers? How can I deal with a flash card that's obviously lying or brain-dead? I apparently don't know the right Google keywords, because I can't find a solution there... ==ml -- Michael W.
