32GB Sandisk Micro SD suddenly stopped being recognized by Galaxy S3 phone

Bought SanDisk 32gb microSDHC UHS-I card(for mobile devices) around October 2012. The card worked flawless until 2weeks ago when I suddenly got a notification “bad removal” “card ejected” (the card never left the phone since the beginning). Already familiar with the tons of complaints (xda,Samsung, Sony- forums) regarding this type of card I began to fear the worst and after struggling for 2 days it just gone blank. No device that I triedsees the card. Also the pc can’t see it anymore.
28gb on video, documents and pictures, all gone.
The most people I read here on the forum mentioned they owned a Samsung device. I do not.
I own a Sony Xperia T (lt30p) with stock android 4.1.2 jelly bean, not rooted.

In those 2 days I had the card monitored by an app and only one time I had the phone restarted(counts for 1 mount and 1 unmount.
The following stats where logged:

Card mounted: 14 times
Card unmounted: 32 times
Card bad removal: 10 times
Card removed: 3 times
Card ejected: 23 times
