data-integrity

I am moving data from an almost dead HDD to an external USB drive using linux , because for some reason Windows cannot see the data. I want to copy a large amount of data over from the HDD to the USB drive with integrity checking. I thought about copying everything over and then checking with md5summer but this would take a reaally long time because its a lot of data and this is not a very powerful PC.

What tool can use to do this on Linux?
