I've been using an adaptec 2940W for sometime with narrow drives and it
has worked flawlessly.

I've hooked up an

ahc0: target 1 using 16Bit transfers
ahc0: target 1 synchronous at 10.0MB/s, offset = 0x8
(ahc0:1:0): "CONNER CP31050 1.05GB 160D" type 0 fixed SCSI 2
sd1(ahc0:1:0): Direct-Access 1013MB (2074880 512 byte sectors)

which works pretty well, but every once in a while I get a slew of:

ahc0: Target Busy
ahc0: Target Busy
...

and an I/O error message from pax or whatever I am using to do the transfers,
for example:

brian@apt>pax -rw Mosaic-src-2.6b2 /usx/home/brian/src
pax: Access/modification time set failed on: /usx/home/brian/src/Mosaic-src-2.6b
2/src/Mosaic-2.6b2-static.gz <Input/output error> 

And some of the data is messed up.

Any ideas what is going wrong?

I'm running 

    FreeBSD 2.0-BUILT-19950601
    P5-90
    16MB/512K Cache
    2940W	                   (terminator off)
      Wide chain
	CONNER CP31050 1.05GB 160D (terminated)
      Narrow chain
	 DEC RZ73     (C) DEC T392
	 TEAC CD-ROM CD-50 1.06    (at end and terminated)
	 WANGTEK 6130-FS 3.04
    Digital DC21040 Ethernet
    Matrox PCI VGA


Lastly, I've tried two different Conners and both experince the same
problem.

Thanks in advance for any help,
