Message-ID: <1420@cit-vax.Caltech.Edu> Date: Sun, 4-Jan-87 00:00:54 EST Article-I.D.: cit-vax.1420 Posted: Sun Jan 4 00:00:54 1987 Date-Received: Sun, 4-Jan-87 03:45:53 EST Organization: California Institute of Technology Lines: 7 Keywords: hp.c bad block replacement I'm thinking of changing the way 4.3bsd hp.c does its bad block replacement, to allow other I/O requests to be satisfied in between retries and revectors. This means that multi-sector transfers will not necessarily be atomic. Is there anything that depends upon disk transfers being atomic?
