I have an 8GB Flash disk (I don't know the exact model). I deleted partitions in GParted, and now it doesn't work. When I want to format the device, it says that "dev/sdb close device failed input/output error"
P.S I cant format disk "Error fsyncing/closing /dev/sdb1: Input/output error"
Output of sudo parted -l /dev/sdb:
Warning: Error fsyncing/closing /dev/sdb1: Input/output error
Retry/Ignore? retry

Your USB stick definitely has a physical defect, so you have to go and replace it.
It looks like a memory cell at some position around 3GB has died. This is not repairable at all (especially not by software)! You can see this because the dd command you used should just write 00h (all bits to zero) to every memory cell on your device, without caring about partitions or file systems. As this did not work, the error is beyond any partitioning and formatting stuff and therefore seems to be hardware.
Sorry for having to say this, but your stick is ready for the dustbin.
