I hadn’t lost any data specifically although certainly have lost the hard drive. The hard drive of my laptop stopped without any warning one day. It was impossible to recover the data on it using disc utilities. I eventually recovered the data. It cost me about £600 from a data recovery company.
I was lucky and the data came back 100% correct, there was no imperfections in it. What often happens in situations like that as you recover the data but you don’t recover all of it. It is distorted or degraded in some ways.
For text files, it doesn’t matter too much. If you have an SPSS data file you only need one byte of that data to be out of place for possibly the entire file to be useless. So backing up data is something to be encouraged.
