newfs error in 5.0.2 with SanDisk SD card



Hi, all.
This is a 128Mb sd card with the usb adaptor. I try to format it with the
steps below:
tree# fdisk sd0
fdisk: Cannot determine the number of heads

Do you want to change our idea of what BIOS thinks? [n]

Installed bootfile doesn't support required options.
Update the bootcode from /usr/mdec/mbr? [n]

We haven't written the MBR back to disk yet.  This is your last chance.

Then I use 4.0.1 boot disk to try it again and no error happen and the disk
can be mounted successfully.

After that, I take the disk under 5.0.2 and try again:

I gor the same error. Does the kernels of 5.0.2 and 4.0.1 treat the disk
in much different way?

p.s. I cc this to port-i386 because I think it shall be happen on i386, too.
     Please also reply to my mailbox, thanks.
