ATA Hard Drive???
i had a 120 maxtor hard drive and it's compatible with ATA/133/100/66/33.
Now, i had just installed my Red hat Linux 9.0 and unfortunately it had assuming my hard drive as 33 PIO Mode Is there anyway i could configure my hard drive connection to DMA ?? Or ATA/133?? any suggestions? |
you can play with the hdparm command...just type hdparm by itself and it will give you a list of available options...you will have to be root to do anything with this command, and if its not in your path then you will have to type /sbin/hdparm .... and just to note since you mentioned it,
hdparm -d1 /dev/hdx will enable dma, and you will replace x with the proper letter corresponding to your device... |
but ...
after i type
$hdparm -d1 /dev/hda5 which was my storage disk and it shows some thing like /dev/hda5: setting using_dma to 1 (on) HDIO_SET_DMA failed: Invalid argument using_dma = 1 (on) why there is a invalid argument? What's wrong? any idea? Also, would u further explain what does "-d1" means ? One more quesion, [root@localhost root]# hdparm /dev/hda5 /dev/hda5: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 14946/255/63, sectors = 73047492, start = 20081313 normaly, shouldn't the underlined phrase be 32-bit? |
