Vista Won't Recognize Seagate External Hard Drive

    I've been searching for ages looking for a solution to this problem but with no luck.

    I have four external hard drives, all Seagate, which are no longer detected by my Vista computer. They don't show up in Computer, or in the Disk Management section. The drives aren't the problem though, because an XP computer reads the drives just fine. The drives are okay, as are the cords, so I'm pretty sure my Vista box is the problem. It takes a while but I can transfer files from XP to the Vista so I have a workaround to use.

    The problem is that there is one of these Seagate drives that was formatted for Mac *and* PC, and the XP box can't read it. It can recognize that there is an external hard drive attached but just shows 0 bytes on everything in Properties, and there's no way to get files off of it.

    So what I need is some help trying to get that Seagate drive to show up on my Vista PC. As mentioned, it plugs in and runs fine as far as I can tell. It's getting power and isn't making any loud noises. But if I go out to Computer or look in the Disk Management section, it doesn't show an external drive attached at all.

    Any suggestions? I've run TSG SysInfo, and here are the results:

    If it was initialised as a GPT drive rather than an MBR drive XP 32 bit can't understand GPT and that's the problem with the XP PC.

    Vista should work with a GPT drive though.

    uninstall Avast, reboot & try to plug the drives in then
    I will hazard a guess that Avast is blocking the drives as an untrusted drive because you ignored a prompt from it or accidentally pressed block drive

    Hi, and sorry for taking so long to reply, I came down with a killer flu virus and only just now got around to trying this.

    Unfortunately, it didn't work. I completely uninstalled Avast, but the drives still don't show up on my computer. Any other ideas? Thanks!
