disk transfer error

[Cathy Accettura]

Last week I was doing a dump and I got this error

DUMP: (this should not happen) bread from /dev/rra1c [block 151984] :
      count = 6144, got -1


I am running Ultrix 3.0 and have a MicroVaxII.  The disk that is 
causing me problems is a Fujitsui Eagle.  

Is there anyway I can use badsect or bad144 to get around this problem
without format the disk.  I thought that badsect was my best bet but
I could not figure out how block and sector related to each other.

The uerf program does show something but no sector number
---- UNIT INFORMATION ----
UNIT CLASS			DSA DISK
UNIT TYPE			RA81
CONTROLLER NO.		      17.
UNIT NO.		      0.
ERROR SYNDROME			DISK TRANSFER ERROR

Should I give up and reformat or is there a way to write the bad sector
into a file.
