I have a WD Ultra 'My Passport' external hard drive and had originally configured it to my MacBook pro, but I just received the surface pro 4 as a gift and I'm trying to use the external hard drive with this device. I saw a post about getting the WD app, and I did that, but it doesn't recognize my device, or at least it is not detecting it. Can I reconfigure it to be read by my surface? I'm not really 100% sure what to do. Hi, We want to make sure that you get the best out of your Surface Pro 4. Here's what we can do to make your external hard drive be detected or recognized by your device: • Please.

Time Machine will back up most of your Mac automatically, but you might want to exclude certain files. Open System Preferences on your Mac. Click Time Machine. Click Options. Click the + button. Choose the files or folders that you wish to exclude. Click Exclude. Time Machine 'Preparing Backup' Process Takes Too Long. Check to see if the preparation process is stuck: Launch System Preferences by clicking its Dock icon, or selecting System Preferences from the Apple menu. Open the Time Machine preference pane by clicking its icon in the System area of the System Preferences window.

• To isolate the issue, you may try another USB drive to make sure other devices are working. If the USB port works fine with other devices other than your external hard drive, here are the troubleshooting steps that you can follow: • Make sure that your Surface Pro 4 is plugged in and connected to the internet. • Press on the Windows key + Q. • Type in Troubleshooting in the search box. • Click on Troubleshooting and choose Hardware and Sound then select Hardware and Devices. Windows f9 shortcut. • Click on Next and follow the on-screen prompts. Let us know how it goes.

To all of you; Apple uses a customized NTFS file system which does not exist in the drive table recognized by Windows and there is no patch or fix unless WD may have an app that can be installed. A hard disk formatted from a Windows computer can be read on a Mac but you cannot write to it (it will tell you it is locked). Since you already have the hard disk formatted for your Windows system, keep it that way. On the Mac, go to the App Store and download/install OneDrive for Mac and transfer your files in that fashion. If you want a drive to backup your Mac, you can get another WD hard disk and reformat it via the Disk utility on the Mac and it will be totally usable 'on the Mac only'.

You can use it to backup all your files on the Mac. The hard disk you have now, use it to backup you Windows system.

Apple did this deliberately a long time ago and there is only one universal solution and that is to get a NAS (Network Attached Storage) drive which hooks up to your router. Those are not machine dependent and both systems can use it. Yea, I had hooked up my mini-HD to my Mac mini to test it out and thought to explore 'why'.

Apple modified a NTFS file system format which does not exist on the drive table listing for formats. There was a regular hard disk at one time that would but it came with a program that you installed on the Mac. The app would act as a 'converter' when accessing the drive and allowed read/write operations. Another reason why Apple never really makes it in the business world. I found out the format structure on my Linux system by taking a spare hard disk and formatting it with my Mac mini and then plugged it into the Linux system which can read/write to both formats. La Cie' may be the maker of that hard disk I mentioned before but has been a really long time before I looked at the issue of using external hard disks with Apple machines. USB pendrives and SD cards are no problem.
