MacBook Pro won't read external HDD

Hi all,

I have an early 2011 MacBook Pro running OS X 10.9.5 (13F34). I have been using a Seagate 2.0 external USB HDD for movies etc, but all of a sudden about a month ago my Mac just stopped reading the Seagate HDD. I cannot access anything on the HDD through the Mac. It reads the HDD in Disk Utility, but if I try and erase/reformat etc I get the same error message repeatedly (Unable to write to the last block of the device).

Can ANYONE help me with this? Please!

Thanks in advance!

Daniel.

Hi OGELTHORPE,

Thanks for the reply. But that isn't working.

The HDD doesn't even show on my desktop.

When I hit COMMAND + I it has a pop-up for my desktop only.

Attach the HDD to the MBP and open Disk Utility.

Click on the Seagate HDD name and volume, each time clicking on the Information icon. See this example:

We have a big problem. The software for these forums occasionally does not show posted images. (not a fault of yours) I cannot see either of yours. Can you see mine?
