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

I updated the drive's firmware, but didn't see anything that would address this issue in any new BIOS updates, so I didn't change the BIOS.

I disabled legacy mode and forced the USB drive to category "hard drive".

Still same problem.

Jeff,



I doubt it will make much difference but in your BIOS is there a
setting called Enabled / Disable USB Legacy mode? In my years of
experience with Dells, this option often made certain USB peripherals
work / appear. And just out of curiosity, have you tried to see if
there is perhaps a firmware update for your external drive? BIOS up to
date too?

        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:

        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:

                  

                  Filesystem

/dev/da0s1   1.9G    635M    1.2G    35%         /media/disk

                  

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?
