I recently bought a Seagate Backup Plus Portable Hard Drive with 1TB of storage. The first time I used it, I was able to drag and drop around 100 photos from my Mac without any problems, but the second time I plugged it in a few weeks later, it won't let me add any files at all to the drive. I am very confused about how to go about fixing this problem, and this is my first hard drive, so I don't really know where to even start.

Connect the external drive to a different computer, and try to copy a few files to it. If you still get "I/O Error", then the unit has malfunctioned.

I would say if you still have your receipt you can always give it a shot...

Hi Hugh
Go to my computer and from the list of drives right click the one that is the seagate drive (probably F ) click open then click and drag files to C;

Make sure your computer has found it and it's supposed to be working fine then replace the USB cable, try another port, uninstall the harware from windows, then unplug the drive and reinstall you may want to try the previous version of software if you can. Also check firmware updates and double check correct windows / OS and bit level.

You can buy USB 3 cables online. like the

5ft USB 3.0 Superspeed Black Cable Cord for Seagate Backup Plus 4TB 3TB 1TB 500G on Amazone for $8.00

USB 3 0 Cable eBay
Perhaps other firms are cheaper?
Perhaps your local electronic store has these cables in stock?

The software is telling you one thing and the Webmaster another. I would trust what the software error is saying to you. I can't even register my Samsung Tab 3 on their site, it asked me to enter the purchase date which I did, 11/16/13. When I tried submitting the form, I got an error telling me the Tab 3 was manufactured 11/30/13, making my purchase date incorrect. Really??!!! My Best Buy receipt didn't lie and I was there at the store that very day, and had purchased the Tab 3.

I don't believe the DVD player would have the resources to translate the files on the hard drive or possible even see the format of the drive.

i am having trouble trying to download music onto my hard drive it will not let me please help
