Hi, The hard disk seems to be functioning ok but I cannot get it to accept any mode above UDMA2! 'hdparm -i /dev/hdc' says the maximum for that drive is UDMA2. 'hdparm -t /dev/hdc' gives a result of only 15MB/s. The DVD-ROM drive is also stuck in UDMA2 whereas an identical drive we have here in a Windows PC is reporting UDMA4. Much google'ing has yielded no solution - has anyone got a better result with this combination?

I have the same setup and the same problem with my SATA drive: Code: /dev/hdc: Timing cached reads: 2504 MB in 2.00 seconds = 1251.56 MB/sec Timing buffered disk reads: 46 MB in 3.11 seconds = 14.78 MB/sec sgreszcz@myth:~$ sudo hdparm /dev/hdc /dev/hdc: multcount = 0 (off) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 24321/255/63, sectors = 390721968, start = 0 sgreszcz@myth:~$ sudo hdparm -i /dev/hdc /dev/hdc: Model=SAMSUNG SP2004C, FwRev=VM100-33, SerialNo=S07GJ10Y514120 Config={ Fixed } RawCHS=16383/16/63, TrkSize=34902, SectSize=554, ECCbytes=4 BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=off CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455 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 UDMA modes: udma0 udma1 udma2 AdvancedPM=no WriteCache=disabled Drive conforms to: unknown: signifies the current active mode I'll let you know if I find anything - there is not much on the net...
