-         If you get this error, try to say Y here:
+       bool "Use multiple sector mode for Programmed Input/Output by default"
+       help
+         This setting is irrelevant for most IDE disks, with direct memory
+         access, to which multiple sector mode does not apply. Multiple sector
+         mode is a feature of most modern IDE hard drives, permitting the
+         transfer of multiple sectors per Programmed Input/Output interrupt,
+         rather than the usual one sector per interrupt. When this feature is
+         enabled, it can reduce operating system overhead for disk Programmed
+         Input/Output. On some systems, it also can increase the data
+         throughput of Programmed Input/Output. Some drives, however, seemed
+         to run slower with multiple sector mode enabled. Some drives claimed
+         to support multiple sector mode, but lost data at some settings.
+         Under rare circumstances, such failures could result in massive
+         filesystem corruption.
+         If you get the following error, try to say Y here:
          hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
          hda: set_multmode: error=0x04 { DriveStatusError }
