For some reason the my IDE is running extremely slow (which accounts for why this box feels so sluggish).
hdparm gives:
/dev/hda:
Model=Maxtor 53073U6, FwRev=DA6207V0, SerialNo=K607RFNC Config={ Fixed } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=60030432 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 *udma4 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive Supports : ATA/ATAPI-4 T13 1153D revision 17 : ATA-1 ATA-2 ATA-3 ATA-4 ATA-5
/dev/hdb:
Model=MAXTOR 4K040H2, FwRev=A08.1500, SerialNo=572124112782 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=32256, SectSize=21298, ECCbytes=4 BuffType=DualPortCache, BuffSize=2000kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=78198750 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no WriteCache=enabled Drive Supports : ATA/ATAPI-5 T13 1321D revision 1 : ATA-1 ATA-2 ATA-3 ATA-4 ATA-5
Both drives claim to be using UDMA if I read the above correctly.
However:
/dev/hda: Timing buffered disk reads: 64 MB in 16.27 seconds = 3.93 MB/sec
/dev/hdb: Timing buffered disk reads: 64 MB in 32.99 seconds = 1.94 MB/sec
1.94MB/sec is *way* to slow for a UDMA5 hard disk surely?
