Hello,

I've a dump(8) created from another USB key of ~3 GByte size and I'm
restoring it into a new created file system on a key which says on
attach:

ugen7.2: <USBest Technology> at usbus7
umass0: <USBest Technology Intenso Premium Line, class 0/0, rev
2.00/1.00, addr 2> on usbus7
umass0:  SCSI over Bulk-Only; quirks = 0x0000
umass0:3:0:-1: Attached to scbus3
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Intenso Premium 0.00> Removable Direct Access SCSI-2 device 
da0: 40.000MB/s transfers
da0: 3853MB (7892087 512 byte sectors: 255H 63S/T 491C)

after around 90 minutes of restore the taget file system says 19 MByte
used (i.e restored):

$ df -kh /mnt
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/da0s1a    3.6G     19M    3.3G     1%    /mnt

What is wrong with this? If this does matter: 8-CURRENT.

Thanks

	matthias
