Sandisk Cruzer Blade 32GB problem

I have a problem with my Sandisk Cruzer Blade 32 GB.

I got it a month ago (even earlier) and now it’s pretty dead and i don’t know why.

It was good for a long time but later i couldn’t write data on it - an I/O error.

Then it said to me that Cruzer isn’t formatted. I tried to format it but it hasn’t formated.

The system couldn’t format it. Other programes like HP … couldn’t do it too.

I’ve got Vista 32-bit. I think i tried everything and read all Net.

Help me please

I think i tried everything and read all Net.

Then you know what to do.  Return it for a replacement.

Additionally, make sure to test it first before accepting the replacement if applicable.
