>Description:
The Western Digital WD400EB disk (40 Gb) is reported by the AlphaBIOS as
`WDC, WD400EB-00CPF0, 06.0, 38166 Mb' (Atapi#0, SCSI bus 0, SCSI id 0) and
operates OK; i can create partitions and format them with the AlphaBIOS, so
the hardware is working .... Western Digital's conception of Gb in the
specs is 10^9 so thats consistent too.

NetBSD, as well as the SRM however (the unix/OSF part of the ``bios'' like
a OFW)  does detect it but doesn't recognize it but only reports a broken
identifier string just like NetBSD does and even Red Hat 7.1 Linux. This
string and the description it gives are allways the same... i.e. its not
noise. The OSF-pal is version 20116.

Have looked at the blocks the disc returned but there might be either
problems with the DMA or so but PIO mode 4 alone (forced with flags)  
doesn't work either...

Accessing the wd0 with `atactl wd0 identify' gives the following results :

Nov 30 03:07:22 starbuck /netbsd: stray isa irq 14
Nov 30 03:07:32 starbuck /netbsd: pciide0:0:0: lost interrupt
Nov 30 03:07:32 starbuck /netbsd:       type: ata tc_bcount: 512 tc_skip: 0
Nov 30 03:07:32 starbuck /netbsd: pciide0:0:0: geometry timed out
Nov 30 03:07:32 starbuck /netbsd: wd0c: device timeout reading fsbn 0 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
..... repeated a few times until it stops logging stray isa irq 14's and 
gives :

starbuck# atactl wd0 identify
Model: oÿo?, Rev: o , Serial #: 
Device type: ATAPI, fixed
Device capabilities:

so i am a bit puzzled but might confirm my ATAPI `sd' type disc hunch ....  
even though several ppl. on ICB have corrected me over and over again that
that was sooo unlikely .... that it wasn't so.

Dunno what to do to fix it... i've had several debug patches and i still 
can't really put my finger on it ...


The uncut dmesg is as follows :

--------------------

	
>How-To-Repeat:
Put the harddisc in a DEC PWS 500au machine and boot the ALPHA kernel; it 
won't recognize the harddisc correctly and accessing it gives trouble. 
Going into the AlphaBIOS when typing in `nt' or `arc' shows the detected 
harddisc correctly.

	
>Fix:
Might be an ATAPI harddisc ? only *new* BIOS'ses can detect and work with
it i was told ... see also the www.wdc.com website for details.
