Что-то меня достали тормоза на моём ноуте. Вроде машинка не сильно старая, но всё как-то медленно. Решил первым делом посмотреть на параметры винчестера. [denis@ogion ~]$ sudo -H hdparm -tT /dev/hda /dev/hda: Timing cached reads: 224 MB in 2.04 seconds = 110.01 MB/sec Timing buffered disk reads: 54 MB in 3.05 seconds = 17.69 MB/sec [denis@ogion ~]$ sudo -H hdparm -iIv /dev/hda /dev/hda: 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 = 65535/16/63, sectors = 78140160, start = 0 Model=FUJITSU MHV2040AT, FwRev=00000096, SerialNo=NS10T5C2E370 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=78140160 IORDY=yes, 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 udma3 udma4 udma5 AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled Drive conforms to: ATA/ATAPI-6 T13 1410D revision 3a: ATA/ATAPI-2 ATA/ATAPI-3 ATA/ATAPI-4 ATA/ATAPI-5 ATA/ATAPI-6 * signifies the current active mode ATA device, with non-removable media Model Number: FUJITSU MHV2040AT Serial Number: NS10T5C2E370 Firmware Revision: 00000096 Standards: Used: ATA/ATAPI-6 T13 1410D revision 3a Supported: 6 5 4 3 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 78140160 device size with M = 1024*1024: 38154 MBytes device size with M = 1000*1000: 40007 MBytes (40 GB) Capabilities: LBA, IORDY(cannot be disabled) Queue depth: 1 Standby timer values: spec'd by Standard, no device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Advanced power management level: 128 (0x80) Recommended acoustic management value: 254, current value: 254 DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=240ns IORDY flow control=120ns ... На сколько я понял, включен режим udma2. У меня такой вопрос, можно ли для этого винчестера включить более быстрый режим, или udma2 для него потолок? И можно ли включть 32-bit для IO_support, или не стоит? -- Всего доброго, Денис.
