Unable to Access Storage Device using Android File Transfer with Kindle Fire !

Bug : Unable to Access Storage Device 

         ( SanDisk 32Gb SD Memory Card ) 

This bug occurred sometime after purchase & usage, But for a time, it was accessible & i was able to load about 4.11Gb of Data onto it. 

            1,202 Photos

            702Mb of Music

            701Mb of Games

            4 Audio Books

            39 Books

            1 NewsStand Item

            3 Personal Videos

The SD Card itself seems to be working properly; as i am able to access all files located on it with The Usual Fire Methods & The File Manager App. 

The Bug is that when i use my Macbook Air with The Android File Transfer Application; The Storage Device becomes invisible; But The Screen on my Macbook Air reveals that The SD Card is in Use & that 25±Gb are Free.

After looking on The Internet for Occurrences & Solutions for this Anomaly, i have discovered that it is occurring across The Board on other Devices; With The Android File Transfer Application as The Common Denominator.

Solutions that i’ve Tried :

            Tried Connecting to The Fire with 3 Different USB Cables, 1 with The White Bar, & 2 with The Black Bar on The Computer End Connector. 

             — Error Remains

            Tried Fiddling with The MTP Options Selector in The Notification Shade ( Comes up while connected to The Macbook Air ) / it has two Options MTP & PTP. MTP is The Default Connection Mode. There is no AFT Setting, which is mentioned in The Internet suggestions. 

             MTP = Media Device / All Purpose Default Setting

             PTP = Camera / Dedicated Photo Transfers ( ? )

             — Error Remains

            Tried Connecting while both The MacBook Air & Kindle Fire were Connected to Wifi Internet.

             — Error Remains

            Tried Connecting to my ‘Other’ ( Earlier Version ) Kindle Fire & The Storage Device on it WAS Accessible. 

             — Error seems to be with The New Gen 5 Kindle Fire, But under what circumstances did it begin ( ? ) 

             If i were casting stones; i might blame an App, probably one that uses a lot of memory, like Real Racing 3. 

            Tried Connecting to The MacBook Air, Turning off The Kindle, So that it would ‘Charge’ more efficiently; then Turned it back on, Connected with The AFT Application.

             — Error Remains

            Tried Connecting to the MacBook Air, turned The Kindle Fire off by holding The Power-Key down for 5_seconds or so. Waited for a few minutes. Turned it back on, then reconnected to The MacBook Air with The AFT Application. 

             Had to pull The Cable several Times and Reconnect to get the AFT Application to Connect with The Fire.
