Bests & Worsts Reviews from Amazon

While downloading files from laptop to Amazon Fire with Sandisk 128GB microSD card, the download froze after 90% complete. Card is corrupted and partial data on card can not be removed. Card can not be re-formatted and additional data can't be added. I've spent hours trying different things to restore the card without success (reformatting, deleting files, registry editor, youtube video searches, etc.) The problem seems common based on large number of internet posts with similar complaints. Worthless and expensive. And I'm hesitant to return the card since it has personal financial tax data that I can't delete.SanDisk 128 GB micro SD Memory Card for All-New Fire Tablets and All-New Fire TV
