I have just recently reformatted and installed windows onto an old hard-disk with a newer computer, and it works fine, but then when connected to an older motherboard it says disk I/O error (despite the bios autodetection working fine). Is there anything I could try to get it going? (The motherboard has worked with this hard drive in the past). Jon PCBUILD's List Owners: Bob Wright<[log in to unmask]> Drew Dunn<[log in to unmask]>
