dscheck(da8): b_bcount 1024 is not on a sector boundary (ssize 4096)

[Rod Person]

Hi,

I'm attempting to mount and external usb ntfs hard drive: 
  <Seagate Backup+  Desk 0406> Fixed Direct Access SCSI-6 device

In FreeBSD I mount it using the fuse driver, but being it isn't
available in DragonFly, I'm just attempting with mount_ntfs. I get
Invalid argument not matter how I try and mount it. I noticed the error:

dscheck(da8): b_bcount 1024 is not on a sector boundary (ssize 4096)

showing up in the dmesg and once when attempting to mount in the
console before starting X. That error doesn't show if I try and mount
in xterm, only writes to dmesg. I assume the the sector boundary is why
I can't mount it, but is there any way around this?


atomizer-dfly# mount_ntfs /dev/da8 /mnt/usb
mount_ntfs: /dev/da8: Invalid argument

also tried /dev/da8s1 same result

atomizer-dfly# dmesg | grep dscheck
