Hello,

I found a ST-225 drive at a local hardware surplus.  First I initialized
the drive with a RQDX3 controller:
- changed the drive select from 1 to 3
- put a PDP11/23+ in the BA23 enclosure
- run XXDP's ZRQC??.BIN on the RD31 -- seemed to work okay

I replaced the PDP11/23+ with a KA640-A, in the same BA23 enclosure.  And
netbooted NetBSD 1.6.  There appears to be some bad blocks:

ra0: drive 0 soft error datagram: unit 0: small disk error, cyl 35: data error (uncorrectable ecc) (code 8, subcode 7)
ra0: drive 0 soft error datagram: unit 0: small disk error, cyl 39: data error (uncorrectable ecc) (code 8, subcode 7)
ra0: drive 0 soft error datagram: unit 0: small disk error, cyl 41: data error (uncorrectable ecc) (code 8, subcode 7)
ra0: drive 0 soft error datagram: unit 0: small disk error, cyl 563: data error (uncorrectable ecc) (code 8, subcode 7)

I assume you have to run rabads to replace the blocks:
- get rabads from
    http://highgate.comm.sfu.ca/pups/4BSD/Distributions/odds-ends/rabads.a.out
- still using the same RQDX3 controller
- netboot rabads

I cannot get rabads to find the RQDX3 controller.  What am I missing?  TIA.
