Did you lose data after you using a Mac? Recently, I encounter a data loss problem. In the process, I find Mac Data Recovery Software reviews and comparisons on the internet. After I tried data rescue and photorec, I have not recovered my photos successfully. At last, I have to seek some help from data recovery service. Except you used a data recovery software ever, you may not judge what is the best one for you. So please give us your experience if you have used a data recovery software on your Mac. This will be helpful for these people: 1. What will cause data loss and tell people how to avoid this. 2. The people can find this easy way to recover their lost data if necessary. Hope you can share this. Thanks.
