Some interesting numbers to compare with your maxtor. The following is using UDMA-33 with near minimal optimization in Mandrake 7.2: Model=IBM-DPTA-372050: /dev/hda: multcount = 16 (on) I/O support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 2495/255/63, sectors = 40088160, start = 0 /dev/hda: Timing buffer-cache reads: 128 MB in 1.08 seconds =118.52 MB/sec Timing buffered disk reads: 64 MB in 2.95 seconds = 21.69 MB/sec Model=IBM-DJNA-371350: /dev/hdb: multcount = 16 (on) I/O support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 1650/255/63, sectors = 26520480, start = 0 /dev/hdb: Timing buffer-cache reads: 128 MB in 1.07 seconds =119.63 MB/sec Timing buffered disk reads: 64 MB in 3.98 seconds = 16.08 MB/sec Tom Berkley Leopold Palomo wrote: > > > I have a maxtor and you the following > > > > hdparm -X66 -u1 -d1 -m11 -c1 /dev/hda > > > > and its works much faster, with no problems > > > > I have tested some parameters and here is the results of hdparm test.
