I suppose the output of hdparm -t /dev/yourdisk is not very cheerful with dma turned off. I recently built a new system and it defaults to dma turned on. I've not edited /etc/defaults/hdparm or /etc/hdparm/.conf. So as to why yours seems to be turned off I do not know. I get this: cevnet:~#hdparm /dev/hda /dev/hda: multcount = 0 (off) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 2048 (on) geometry = 65535/16/63, sectors = 80293248, start = 0 cevnet:~#hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 92 MB in 3.14 seconds = 29.31 MB/sec the other disc does better than that though: cevnet:~#hdparm /dev/hdb /dev/hdb: multcount = 0 (off) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 2048 (on) geometry = 24792/255/63, sectors = 398297088, start = 0 cevnet:~#hdparm -t /dev/hdb /dev/hdb: Timing buffered disk reads: 172 MB in 3.02 seconds = 56.95 MB/sec -- Chris <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
