Description of problem: The hard disk on this PC was running with udma with Fedora Core 3. FC5's hdparm now says otherwise. Either it is NOT using udma or hdparm tells the wrong story. Version-Release number of selected component (if applicable): hdparm-6.3-2.2 How reproducible: hdparm -iv /dev/hdb Steps to Reproduce: 1. 2. 3. Actual results: hdparm says "no udma", because there is no "*" behind a udma mode. However, using_dma is 1. I do not remember, if udma mode was udma2 or udma4 on FC3. # hdparm -iv /dev/hdb /dev/hdb: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 16383/255/63, sectors = 156368016, start = 0 Model=SAMSUNG SV0802N, FwRev=TP100-24, SerialNo=S019J10XB28950 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=34902, SectSize=554, ECCbytes=4 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=156368016 IORDY=on/off, tPIO={min:240,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=enabled Drive conforms to: (null): ATA/ATAPI-1 ATA/ATAPI-2 ATA/ATAPI-3 ATA/ATAPI-4 ATA/ATAPI-5 ATA/ATAPI-6 ATA/ATAPI-7 dmesg suggests UDMA(100) is available: # dmesg | grep hdb ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:DMA hdb: SAMSUNG SV0802N, ATA DISK drive hdb: max request size: 512KiB hdb: 156368016 sectors (80060 MB) w/2048KiB Cache, CHS=16383/255/63, UDMA(100) hdb: cache flushes supported hdb: hdb1 hdb2 hdb3 hdb4 EXT3 FS on hdb2, internal journal EXT3 FS on hdb1, internal journal Adding 1052248k swap on /dev/hdb3.
