Mar 12, 2015 - How-To: Choose the best external hard drive for your Mac (or iOS device!). Backup Plus Slim portable drives are similar up until the 4TB mark,.
I have a 2013 iMac 27' with 750GB SSD and i7 running latest release of Mavericks OSX 10.9.3 (13D65) and have been using a Seagate Backup Plus 4TB USB Drive exclusively for Time Machine Backups. Seagate's Website says the Drive has the latest Firmware Update (I checked because earlier posts suggested this as a solution to similar problems). The Drive and Time Machine worked great together until 20 days ago when Time Machine Began reporting that the system had not been backed up recently (I should say it now reports it has not backed up in 20 days.
I can temporarily remount the drive by unplugging it from the USB Port and it's external Power Supply and rebooting the iMac and then Powering up the Drive and then plugging in the USB Cable. This is how I was able to check on Seagate's website to make sure the firmware was up to date. It will begin a Time Machine Backup and then give an error message stating Do Not Remove the Drive without Ejecting It Properly. I have not tried to eject the drive it simply stops being recognized by my iMac. Time Machine sees the various Backups while the drive is working and will try to start a backup but then simply stops seeing the drive after 2-5 Minutes. The USB Drive was formatted by OS X Mavericks and as I said worked fine for several months.
I do extensive Book Design and App Development for a Ministry I volunteer my time for and for my local church and I am very concerned about not having a current back-up. My USB Drive reports that it has a little over 3TB of available space of 3.64 TB total so this is not a question of lack of capacity. I welcome any thoughts and suggestions. I am relatively new to the Mac World (this is my first Mac in many years) and although I know how to diagnose and usually correct issues with a Windows PC I am not there yet with the Apple Mac environment. I am a long time user of micro computers and am generally viewed as knowledgeable and capable. In fact I used to own a chain of computer stores that sold Apple, IBM, Compaq, HP and other brands but that was many years ago so I am only recently a Mac User again. Thanks very much for anyone viewing this and offering suggestions - I really appreciate any help.
Is the drive formatted with the Seagate software? It's best NOT to use the software that comes with the drive but to use Apple's Disk Utility to format the drive. However if you did use the Seagate software, you can try running Repair Drive from Disk Utility in Applications/Utilities on the drive. You'll know it was formatted by Seagate if you see a custom drive image in a Finder Window. You'll also see Seagate software on the drive. If this fails to fix, you need to reformat using Disk Utility. This will erase all data on the drive so you would have to backup first.
Finally, the 4T drives don't have the best track records.The Seagate 2T and 3T drives are more reliable than the 4T. Personally, I would rather have two 2T drives than one 4T drive. That's a lot of data to loose if the drive goes bad. From the menu bar, select ▹ System Preferences ▹ Energy Saver ▹ Power Adapter and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked. If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends. Try a different cable. If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac. If you're connecting it directly, try a different port. Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac. If the drive is bus-powered, but has an AC adapter, connect the adapter.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock. Apple Footer.
