I also had a lot of hard drives die (like 7 by now). Also I have a lot |
| 19 |
of not to use anymore backup CDs and DVDs. They become old and that |
| 20 |
isn't to good for them. One should backup a CD/DVD every year or so |
| 21 |
(don't trust the "this dvd is golden and will be there in 100 years". I |
| 22 |
am extremely sure they did't test it, yet ;-) ) |

Also there have been articles that if one drive of a raid dies there is |
| 25 |
a chance that you cannot recover your data. This is based on the theory, |
| 26 |
that one of the other drives have hidden errors. The chances for this |
| 27 |
grow with the size of the hd. |
