Folks,

I have a Seagate drive that will not let me edit mode pages. 

scsi -f /dev/rsd2c -m 1 give me this:

------------------------------------------------------------
AWRE (Auto Write Reallocation Enbld):  0 
ARRE (Auto Read Reallocation Enbld):  0 
TB (Transfer Block):  1 
RC (Read Continuous):  0 
EER (Enable Early Recovery):  0 
PER (Post Error):  1 
DTE (Disable Transfer on Error):  0 
DCR (Disable Correction):  0 
Read Retry Count:  27 
Correction Span:  12 
Head Offset Count:  0 
Data Strobe Offset Count:  0 
Write Retry Count:  1 
Recovery Time Limit:  65535 
-----------------------------------------------------------

If I execute scsi -f /dev/rsd2c -m 1 -P 3 -e (and even if no changes are 
made), I get this:

------------------------------------------------------------------------------
SCIOCCOMMAND ioctl: Command accepted.
return status 3 (Sense Returned)Command out (6 of 6):

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

The disk is a Seagate ST-43400N Download Revision Code 0116.

Anyone have any ideas?  The other 3 drives like this one accept the mode 
changes gracefully.  They are a different revision code however.

Thanks,

Craig
