After reading a lot of posts in this forum regarding problems creating good backup images on external USB 2.0/Firewire drives, I thought it might be helpful if those who have drives that work well with very large files would post the specifications here. Some have mentioned the specs of their working drives, others have not. Rather than hunting all over, it would be nice to have them listed in one thread. Since the chipset seems to make a big difference in some cases, we need information such as the make/model of the external drive enclosure, the USB 2.0/Firewire chipset it uses, the chipset of your motherboard if using motherboard USB 2.0/Firewire ports or the chipset of your USB 2.0/firewire PCI or laptop PC Card if you are connecting the drive to one of those. My interest is in finding a good external USB 2.0 or Firewire enclosure for my WD 250 GB IDE drive that works well with the nVidia nForce2 chipset on my motherboard. Of course, by "works well" I mean can read/write large (>10GB) Acronis images and other files without corruption. If nothing works well with nForce2, I'll have to go with a PCI card. Others will have different configurations for which they need a working solution. Thanks in advance for any useful responses in this thread. I am sure there are many who can benefit from this information.
