>Description:
I have a system with an IDE Compact Flash reader as 
a slave drive.  I've used it to succesfully mount 1Gb
MicroDrives, but when I boot with a 256Mb CF, I get the 
following:

  ad0: 19092MB <WDC WD200BB-00AUA1 18.20D18> at ata0-master UDMA100
  ad1: FAILURE - SETFEATURES SET TRANSFER MODE status=51<READY,DSC,ERROR> error=4<ABORTED>
  ad1: 244MB <TOSHIBA THNCF256MMA 3.00> at ata0-slave BIOSPIO

attempting to run bsdlabel ('bsdlabel ad1s1') on the drive causes 
the system to loop, or in some cases, panic:

g_vfs_done():ad0s1d[WRITE(offset=1740455936, length=10240)]error = 6
g_vfs_done():ad0s1d[WRITE(offset=1740455936, length=10240)]error = 6
g_vfs_done():ad0s1d[WRITE(offset=1740455936, length=10240)]error = 6
g_vfs_done():ad0s1d[WRITE(offset=1740455936, length=10240)]error = 6
g_vfs_done():ad0s1d[WRITE(offset=1740455936, length=10240)]error = 6
