I have a functional old PC operating under XP home, handles basic tasks and internet well. It is networked and I use it as a temporary back up device also. I have a 40GB IDE drive (NTFS) as the primary and a 8 GB (NTFS) as the secondary. Apart from the details listed, the controller is Intel 82371AB/EB PCI Bus Master IDE. I would like to increased the capacity of the IDE slave to the largest capacity that the system will handle. I realise that some would advise it is not worth the electrons or time in maintaining the unit but it is still functioning well, within the limits of the technology of its day.
I would appreciate advice in regard to what currently available new IDE drives would function in this sytem, max capacity, possible limitations and potential problems.
