It seems like a harddrive access problem, assuming the mp3's are local. Try (in single user mode) hdparm /dev/hda (presumably) and make sure that it looks something like: /dev/hdb: 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 = 8 (on) geometry = 116301/16/63, sectors = 117231408, start = 0 busstate = 1 (on)
If it doesn't, hdparm -t -T to test the speed, tweak the settings and repeat the test. SCSI is of course faster, but even IDE is pretty good: /dev/hdb: Timing buffer-cache reads: 128 MB in 1.01 seconds =126.73 MB/sec Timing buffered disk reads: 64 MB in 2.01 seconds = 31.84 MB/sec Enjoy. Steve
