Faulty SD Card

I have a faulty SD card taken from a Sony phone which has loads of pictures on it.
The phone no longer sees it and neither does the computer when I plug it via the phone or a USB card reader.
I have tried various trial software to read card but to no avail.

Can anyone recommend a course of action orsome software that is likely to work.

The problem at the moment is that the card does not appear as a
logical drive and hence the software can not interogate it. Any technical advice would be very much appreciated.
