Dotaz: pomale citanie z ide disku

[foxicatko]

Hello.

kupil som si novy disk hitachi travelstar 5k100 80GB 2.5" ako nahradu za stary. zda sa ze bios (kernel?) zle detekuje jeho geometriu tak ju nastavujem pomocou parametra 'hda' pri boote.

pri defaultnej geometrii disk skoro neslo pouzit pre haldu chyb (zrejme nasledok poziadavkov na neexistujuce sektory).

odkedy je nastavena rucne errory zmizli, ale vysktli sa ine problemy... disk uplne zufalo pomaly cita data zo seba, pricom ledka neustale svieti, na gkrellm to vyzera tak, ze precita normalne zhruba 50MB a potom padne na 0-260KB.... ale zapis je v poho...

okrem tohto bezi s "-A1 -W1 -X udma2" - vyssiu udma asi nepodporuje radic. skusal som hadam vsetky kombinacie parametrov.. bezvysledne

hdparm -Tt /dev/hda:

Timing cached reads:   532 MB in  2.01 seconds = 265.22 MB/sec
Timing buffered disk reads:   58 MB in  3.04 seconds =  19.10 MB/sec

najdivnejsie na tom je ze hdparm -Tt cita disk v pohode ale akykolvek iny pokus je uplne marny.

presiel som dmesg a nevsimol som si tam nic podozrive co by sa tykalo diskov alebo radica.
lspci -v:

        I/O ports at fcf0 [size=16]


niekde som cital ze by to mohlo byt skosobene zlou kabelazou, ale stary disk siel v poho a je to v notebooku takze neviem ako by som sa k nej dostal.

co s tym? :(

Na otázku zatím nikdo bohužel neodpověděl.
