Thank you John, Just more info about it. Last night i did not give up and tried any BIOS settings i could think of but still the problem existed except when i tried:
chdir to /extra ( this is on /dev/hdc1 ) tried a ftp session to retrieve a zipped file - lo and behold, i can download it ( 300K size ) at 3.1K bytes per second. quit to session and cd to my home directory ( /dev/hda ) started a ftp session and download the same file to that directory BAD now, the transfer rate was 2.6 K bytes per second. This could mean that there are some problems with my /dev/hda which is a quantum fireball 1G disk. So far i did not get bad sectors in dos, linux always started and said disks clean. PS: the drive on /dev/hdc is an old Maxtor 345 M harddisk (ATA mode 2 ). I may try your suggestions later and hope that will solve download problem. Regards. Paul John T.
