 (drive relocated to sd0 due to some hot-plugging, but it is the same
 device.)
 
 netbsd# dd if=/dev/rsd0e of=/dev/null bs=64k count=4000
 4000+0 records in
 4000+0 records out
 262144000 bytes transferred in 8.804 secs (29775556 bytes/sec)
 
 this is comparable to performance under linux:
 
 linux# dd if=/dev/sdc1 of=/dev/null count=800000
 800000+0 records in
 800000+0 records out
 409600000 bytes (410 MB) copied, 12.66 s, 32.4 MB/s
 
 the raw device cannot be mounted by ntfs-3g under NetBSD:
 
 netbsd# ntfs-3g /dev/rsd0e /mnt -o force,uid=100,gid=100,umask=222
 ntfs_attr_pread: ntfs_pread failed: Invalid argument
 Failed to read NTFS $Bitmap: Invalid argument
