Lost datas.

[Silverthorn]

That HD can be bugged in two ways.

Easy problem: only the MBR is broken; means: all your files are still uncorrupted on the HD, just the index went suicidal. There is some software allowing you to retrieve data. Helped me when my computer crashed like 8 years-ish ago. Don't remember what I used, though.

Hard problem: actual files are corrupted. Those will most likely be lost -- you can still try to recover the others.

Either way, I guess you guys should start creating backups once or twice a year to avoid crashes to that extent. Considering that external HDs are fairly cheap, this would be recommendable in the future.

Hope you get it sorted.
