- Something like "Data buffer overrun", followed by a "SCSI bus reset--
- target <blah> now syncronous at 4.0 M/s"?
-
- You may be SOL...I've know several devices that work fine on the NeXT
- but fail to work on Suns (specifically, SPARCstation II's and IPX's).
- One example was a Wangtek 6200 DAT tape drive that failed completely,
- another was a Fujitsu 2266SA (1.1 Gig 5.25" HD) that had to be
- reformatted on my NeXT for 512 byte sectors, rather than 1K, before the
- Sun would touch it.
-
- Sun boxes seem to have problems with devices that can't accept 512 byte
- sectoring. The NeXT is much more intelligent about such things.
-
- It might be helpful for you to describe what Sun machine you're using,
- and to possibly include a transcript of the SCSI bus errors.
