+\fBdk%d%c: write locked\fP.
+An attempt was made to write to a drive that is physically write-protected.
+.PP
+\fBdk%d%c: controller err %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d) status %b ecode %x; resetting controller... retrying\fP.
+.br
+\fBdk%d%c: drive err %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d) status %b ecode %x; resetting drive... retrying\fP.
+An attempted transfer resulted in a controller or drive error.
+The controller or drive is reset, and the transfer is attempted
+a second time.
+.PP
+\fBdk%d%c: hard error %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d)
+status %b ecode %x\fP.
+An unrecoverable error was encountered. The filesystem block number reported
+is a logical sector number on the indicated partition;
+it is expressed using 1024-byte sectors.
+If the transfer involved multiple blocks, the block range is printed as well.
+The parenthesized fields list the actual disk sector number
+relative to the beginning of the drive
+(in 512- or 1024-byte blocks, as appropriate),
+as well as the cylinder, track and sector number of the block.
+The error status field of the device control
+block is printed in hexadecimal followed by a symbolic description.
+If this is an SMDE controller, the error code is also displayed.
+.PP
+\fBdk%d%c: soft error %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d)
+status %b ecode %x\fP.
+A recoverable error was detected by the controller.
+The fields are interpreted in the same way as those for hard errors.
+.PP
+\fBdk%d%c: soft ecc %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d)\fP.
+A recoverable ECC error was detected and corrected by the controller
+during the indicated transfer.
+.PP
+\fBvd%d: drive %d: couldn't reset\fP.
+The system was unable to reconfigure a drive during a controller reset.
+.PP
+\fBvd%d: controller timeout\fP.
+The controller failed to complete an operation within a reasonable
+time. This message is usually followed by another message indicating
+what operation timed out; e.g. ``during config'' for a configuration
+command.
