Please excuse this if its a configuration issue: The IDE drives i have are showing ~4-5MB/sec with hdparm in 2.3.51, they usually show 19-21 in kernel 2.2.x
cold:~% /sbin/hdparm -c1 -d1 -k1 -m16 -W1 /dev/hda
/dev/hda: setting 32-bit I/O support flag to 1 setting multcount to 16 setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted setting keep_settings to 1 (on) setting drive write-caching to 1 (on) multcount = 16 (on) I/O support = 1 (32-bit) using_dma = 0 (off) keepsettings = 1 (on)
