    Slow copy from CDROM


    Hi guys
    a simple inquirie, that I'm sure you'll have answers on
    I have a problem with a cdrom of mine,
    It work perfect Usualy... except under linux
    I'm trying to copy from the cd to my HD, and the transfer rate is from 1.5Mb (rarely) to an average of 50Kb/Sec... which doesnt satisfy me at all!

    I though that mabye the dma wasnt on... but it is...
    I dont really know if any other param could change something... so here my reading on hdparm...
    Code:
    /sbin/hdparm /dev/hdc
    
    /dev/hdc:
     HDIO_GET_MULTCOUNT failed: Invalid argument
     IO_support   =  1 (32-bit)
     unmaskirq    =  1 (on)
     using_dma    =  1 (on)
     keepsettings =  0 (off)
     readonly     =  0 (off)
     readahead    = 256 (on)
     HDIO_GETGEO failed: Invalid argument
    Thanks a lot for your suggestions

    That is weird... I don't think this is it, but check what the dma settings are in the BIOS.
