Sounds like you already have smartmontools installed. Use smartctl to look at your disks SMART data and also run the built in diagnostics.
ddrescue is a good tool to recover your data. Look at the example section in the manual. info ddrescue. The first pass will read the whole disk with a large block size, skipping all read errors to save as much as possible as quickly as possible. The second run then reads only the failed sectors from the first run with smaller block sizes and retries multiple times. Then fsck the fresh copy and hope you got everything. I just did this successfully on a windows drive. Only one 512b block failed completely.
