I've googled and found that this particular product might be "defective by factory". Anyone has an idea how to make it accessible with FreeBSD? In order to have maximal abilities for data transfer, this stick is msdosfs formatted. But no proper device will occur if plugged in. Some data here: umass0: on uhub3 da0 at umass-sim0 bus 0 target 0 lun 0 da0: Removable Direct Access SCSI-0 device da0: 1.000MB/s transfers da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present umass0: at uhub3 port 1 (addr 2) disconnected (da0:umass-sim0:0:0:0): lost device (da0:umass-sim0:0:0:0): removing device entry umass0: detached There is only /dev/da0. % fdisk da0 ******* Working on device /dev/da0 ******* parameters extracted from in-core disklabel are: cylinders=977 heads=255 sectors/track=63 (16065 blks/cyl) parameters to be used for BIOS calculations are: cylinders=977 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 11 (0x0b),(DOS or Windows 95 with 32 bit FAT) start 44, size 15679396 (7655 Meg), flag 0 beg: cyl 0/ head 0/ sector 45; end: cyl 975/ head 254/ sector 63 The data for partition 2 is: The data for partition 3 is: The data for partition 4 is: Sothe partition data can be read, why is there no device file to access the partition? because of the line "da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present" I think it's not possible to get rid of this problem by reformatting the stick. I think about returning it to the vendor with a hardcopy of dmesg which reveals that the stick is defect. :-) Thanks for any recommendations. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
