config IDEDISK_MULTI_MODE
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 }
If in doubt, say N.
