Looking for help with corrupted SD card

Hello, this is my first post and I am not techincally minded at all but I am desperate to sort out my micro sd card which has been in my HTC android phone and has become corrputed.

I will start at the beginning, firstly I broke the phone, I smashed the screen. So, being not technically minded I thought I would have to use a Micro SD card reader to recover all of the photos on the disc. Bad move!!! The card reader seems to have corrputed the disk. When I mount the disk back into the phone and look at the drive through my computer, under the properties of the selected drive it says unknown file system and 0 bytes. I have tried Recuva and it says the parameters are incorrect, I've tried EaseUS recovery but it again says there is nothing on the disk when I select the partition recovery option. (I've done all this by drawing information from the internet on the best way to recover it) nothing is working and I am at my wits end with. The disk has very imnportant photos on of my family. If anyone can help me I would be most grateful :-)

Can anyone help?

I'm a bit confused about your mentioning of the disk being corrupted. Which disk do you mean? Or are you talking about the phone's internal memory?

Do you mean you inserted a micro sd card to try and transfer the photos from the phone onto a card and now there seems to be nothing on the phone and nothing on the card?
