16 GB Cruzer blade turned to 64MB Firebird

Hi all,

Recently I received a San disk cruzeer blade 16GB pen drive as a gift.

When I plugged it into my laptop, it asked for format and I was not able to format also.

It changed to 64 MB San Disk Firebird and the pen drive size remains the same.

Kindly help me in this regard. Thank you

IMO It is either counterfeit or defective and needs to be returned to where it was purchased or to SanDisk directive.
