Thanks for your help, I was going to I guess an old tutorial I found my searching google....
http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html and http://www.linuxgazette.com/issue79/punk.html im using an old Compaq Presario MB that has a slot1 p3 550, and it wouldn't take the 69, so I had to go back to the 66 and it worked...still only 4MB/sec though, as for the ones on the ATA133 card here are the results when I get the info on the drives: /dev/hda: Timing buffer-cache reads: 128 MB in 1.32 seconds = 96.97 MB/sec Timing buffered disk reads: 64 MB in 14.93 seconds = 4.29 MB/sec /dev/hdb: Timing buffer-cache reads: 128 MB in 1.28 seconds =100.00 MB/sec Timing buffered disk reads: 64 MB in 14.69 seconds = 4.36 MB/sec /dev/hde: Timing buffer-cache reads: 128 MB in 1.29 seconds = 99.22 MB/sec Timing buffered disk reads: 64 MB in 43.21 seconds = 1.48 MB/sec /dev/hdf: Timing buffer-cache reads: 128 MB in 1.30 seconds = 98.46 MB/sec Timing buffered disk reads: 64 MB in 1.84 seconds = 34.78 MB/sec /dev/hdg: Timing buffer-cache reads: 128 MB in 1.30 seconds = 98.46 MB/sec Timing buffered disk reads: 64 MB in 1.94 seconds = 32.99 MB/sec /dev/hdh: Timing buffer-cache reads: 128 MB in 1.29 seconds = 99.22 MB/sec Timing buffered disk reads: 64 MB in 45.16 seconds = 1.42 MB/sec /dev/hde: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 0 (off) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 16 (on) geometry = 155061/16/63, sectors = 156301488, start = 0 busstate = 1 (on) /dev/hdf: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 16 (on) geometry = 155061/16/63, sectors = 156301488, start = 0 busstate = 1 (on) /dev/hdg: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 16 (on) geometry = 14589/255/63, sectors = 234375000, start = 0 busstate = 1 (on) /dev/hdh: multcount = 0 (off) I/O support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 0 (off) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 16 (on) geometry = 14589/255/63, sectors = 234375000, start = 0 busstate = 1 (on) why didn't it turn on anything on for hdh? And it didn't turn DMA on for hde? Hdf and hdg look good.... Here is my config: hdparm -q -X66 -u1 -m16 -c1 -a16 /dev/hda hdparm -q -X66 -u1 -m16 -c1 -a16 /dev/hdb hdparm -q -X69 -d1 -u1 -m16 -c1 -a16 /dev/hde hdparm -q -X69 -d1 -u1 -m16 -c1 -a16 /dev/hdf hdparm -q -X69 -d1 -u1 -m16 -c1 -a16 /dev/hdg hdparm -q -X69 -d1 -u1 -m16 -c1 -a16 /dev/hdh also I have been getting errors at boot even before I started messing with this stuff....here is some of the stuff I get with dmesg.....
