[问题]我的IDE硬盘被识别成Sata了！

[nabisco]

RT，我的IDE硬盘被识别成Sata类型，导致我无法用hdparm来优化硬盘参数，现在的硬盘参数如下：
/dev/sda:

IO_support = 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 4864/255/63, sectors = 78140160, start = 0

Timing cached reads: 1376 MB in 2.00 seconds = 686.93 MB/sec
Timing buffered disk reads: 92 MB in 3.02 seconds = 30.46 MB/sec

好像速度有点慢啊。怎么办？
