Yes, Sir. my BIOS can see this Samsung SP1203N/DOM is the second master HDD. In addtion, output of command dmesg | grep "^hd" includes hdc: SAMSUNG SP1203N, ATA DISK drive So, I think my box can find this harddisk. However, fdisk can not open /dev/hdc and mkfs.ext3 -c /dev/hdc shows: mk2fs 1.32 (09-Nov-2002) mkfs.ext3: Input/output error while trying to determine filesystem size. One thing I find is that if I just use this one disk to install redhat9.0, it can be find by install program and can be formatted. After connecting to the second master HDD, it looks fdisk and mkfs.ext3 will not work. I don't know why? I already tried 2 days. Warm regards, Z.
