(Whoops, ninja’d.)

If the drives are not encrypted, just stick them in an external enclosure and connect them on a computer you are using to access the data. (I’m guessing they’re Windows boxes, no Bitlocker.)

If the data is encrypted... good luck.

To wipe... sdelete works fine. Search for Sysinternals sdelete: https://docs.microsoft.com/en-us/sys...nloads/sdelete

You can either format it or delete just the specific data, then run sdelete w/ -c flag and a 3-pass run.

For the drop-off... best to do a format & fresh install if you have the discs.
