137 | This setting is irrelevant for most IDE disks, with direct memory | ||
138 | access, to which multiple sector mode does not apply. Multiple sector | ||
139 | mode is a feature of most modern IDE hard drives, permitting the | ||
140 | transfer of multiple sectors per Programmed Input/Output interrupt, | ||
141 | rather than the usual one sector per interrupt. When this feature is | ||
142 | enabled, it can reduce operating system overhead for disk Programmed | ||
143 | Input/Output. On some systems, it also can increase the data | ||
144 | throughput of Programmed Input/Output. Some drives, however, seemed | ||
145 | to run slower with multiple sector mode enabled. Some drives claimed | ||
146 | to support multiple sector mode, but lost data at some settings. | ||
147 | Under rare circumstances, such failures could result in massive | ||
148 | filesystem corruption. | ||
