I use my micro sd to flash custom rom to my htc hd2 and then today, I want to reformat my micro sd using sd formatter. When it is formatting it shows an error cannot format....... , then when I go to computers, the micro sd does not show up. I take it out and then put it back and then it showed up. Then I use minitool partition wizard to make a partition, my step are:

Delete partition>apply
that's my steps that I took, after apply the disk gone, just gone, I take it out and then put it back and then it showed up but only in minitool partition wizard. The file system says its bad disk, I can't do anything with it.
Is there any program or config that I can use to repair my micro sd or just buy a new one.
sorry bad English

thank you
