[PC-BSD Testing] Dolphin thinks external HD is full but it isn't

I reformatted the drive to UFS2 after I bought it.  It was formatted for Windows - don't recall the file system.

I have a thread at FBSD forums too, but no joy yet.

Anyway, I have an internal 500GB HD that works fine.  Compare the two Fdisk outputs for clues.  Something doesn't look right:

******* Working on device /dev/da0s1 *******
parameters extracted from in-core disklabel are:
cylinders=121600 heads=255 sectors/track=63 (16065 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=121600 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:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
    start 0, size 50000 (24 Meg), flag 80 (active)
        beg: cyl 0/ head 0/ sector 1;
        end: cyl 1023/ head 254/ sector 63
------------------------------------------------------------------
Compared to a 500GB internal drive I also have:

        I removed all files from the drive and now it reports
1.2GB free.

        

# df -h shows:

Yet Dolphin reports the drive size as 931.5 GiB which seems about right.

        

Sysinstall shows:

Anyone else have this problem?

        

        
      
    
  



I've not run into this problem before... Your external disk drive is
formatted UFS though, right? Does FAT32 fare any better, since that's
what most of the external drives I've tested use?
