I've got an old IDE disk (Western Digital AC2420H) that I want to copy
data off from. I plugged it into my fairly recent system (Gigabyte
7IEX4 motherboard, bought in 2000). However, linux can't read the
disk. The disk is identified, but the partition table and other data
can't be read from it. I tried reconfiguring the kernel with
CONFIG_IDEDISK_MULTI_MODE based on a google search and kernel config
documentation but that didn't change anything. Relevant dmesg output
follows. Any suggestions?
