Totus Copy is a utility for transferring data off of a failing hard drive. OS X has a number of safety features built into it's copy functions, if it detects an I/O error or a stalled read the transfer will fail. OS X also gets file information for all files before it even copies the first one. While these are great functions to prevent further damage to a hard drive it makes it very difficult to transfer data.
Totus Copy will scan a failing hard drive and recover the files from it onto a separate functional hard drive. It does this by using a very gentle non-intrusive scanning method. Unlike other transfer utilities there is no timeout for file copies. If the data is readable Totus Copy will transfer it. Although this will cause more damage to your hard drive it has a high success rate of retrieving data.
