Hello. I've a 4GB USB memory which is formatted as a single FAT32 partition. When I insert it, I get: > root: Unknown USB device: vendor 0x1e3d product 0x2092 bus uhub5 > kernel: ugen5.3: <USB0911B> at usbus5 > kernel: umass1: <USB0911B Flash Disk, class 0/0, rev 2.00/1.00, addr 3> on usbus5 > kernel: umass1: SCSI over Bulk-Only; quirks = 0x0000 > kernel: umass1:3:1:-1: Attached to scbus3 > kernel: da6 at umass-sim1 bus 1 scbus3 target 0 lun 0 > kernel: da6: <USB0911B Flash Disk 5.00> Removable Direct Access SCSI-2 device > kernel: da6: 40.000MB/s transfers > kernel: da6: 3855MB (7895040 512 byte sectors: 255H 63S/T 491C) > kernel: GEOM: da6: geometry does not match label (16h,63s != 255h,63s). > kernel: GEOM: da6: media size does not match label. > # ls /dev/|grep da6 > da6 > da6a (I'd expect da6s1, instead of da6a...) > # fdisk /dev/da6 > ******* Working on device /dev/da6 ******* > parameters extracted from in-core disklabel are: > cylinders=491 heads=255 sectors/track=63 (16065 blks/cyl) > > parameters to be used for BIOS calculations are: > cylinders=491 heads=255 sectors/track=63 (16065 blks/cyl) > > Media sector size is 512 > Warning: BIOS sector numbering starts with sector 1 > Information from DOS bootblock is: > The data for partition 1 is: > sysid 6 (0x06),(Primary DOS, 16 bit FAT (>= 32MB)) > start 63, size 7887852 (3851 Meg), flag 0 > beg: cyl 0/ head 1/ sector 1; > end: cyl 490/ head 254/ sector 63 > The data for partition 2 is: > <UNUSED> > The data for partition 3 is: > <UNUSED> > The data for partition 4 is: > <UNUSED> > # mount -t msdosfs /dev/da6a /mnt/ > # df > Filesystem 1K-blocks Used Avail Capacity Mounted on > ... > /dev/da6a 399904 4048 395856 1% /mnt Now... isn't that a tenfold error? > # df -h > Filesystem Size Used Avail Capacity Mounted on > ... > /dev/da6a 391M 4.0M 387M 1% /mnt The partition should be 4GB, not 400MB... Any hint on this? System is 8.1-RELEASE-p2/i386. bye & Thanks av.
