After reading this part (Page 12) of the ArsTechnica review of Lion, I'm quite fearful for my data.
"That feeling is compounded by the most glaring omission in HFS+and, to be fair, many other file systems as well. HFS+ does not concern itself with data integrity. The underlying hardware is trusted implicitly. If a few bits or bytes get flipped one way or the other by the hardware, HFS+ won't notice. This applies to both metadata and the file data itself.
Data corruption in file system metadata structures can render a directory or an entire disk unreadable. (For a double-whammy, think about corruption that affects the "HFS+ Private Data" directory where every single hard link file on a Time Machine volume is stored.) Corruption in file data is arguably worse because it's much more likely to go undetected. Over time, it can propagate into all your backups. When it's finally discovered, perhaps years later when looking at old baby pictures, it's too late to do anything about it."
Is there any way for us to prevent data corruption? I have lots of data that I have spent long hours on and would not like them to simply fade away in to the ether.
