I get this when trying to newfs my new drive:

# newfs /dev/rsd2e

...

sd2(ahc0:2:0): data overrun of 5108 bytes detected. Forcing a retry.

   I'm running current from a couple weeks ago:

NetBSD wheel.tiac.net 1.2G NetBSD 1.2G (WHEEL) #2: Thu Aug 14 20:31:06 EDT 1997     gary@wheel.tiac.net:/altroot/local/build/NetBSD/sys/arch/i386/compile/WHEEL i386

The drive is:

sd2 at scsibus0 targ 2 lun 0: <MICROP, 4345WS, x43h> SCSI2 0/direct fixed
sd2: 4340MB, 4811 cyl, 11 head, 167 sec, 512 bytes/sect x 8890029 sectors

And it is labeled as:

Is this likely a hardware or config problem? newfs seems to write most
of the superblock copies before it eventually dies. I'd prefer a
software bug, of course...
   Thanks.
