May be. But I have just finished testing its first 41 GB with |
| 32 |
# badblocks -sw -b4096 |
| 33 |
|
| 34 |
Three passes with different write patterns took about 2 hours 10 minutes, |
| 35 |
that is about 33 minutes per pass. |
| 36 |
|
| 37 |
So, the full one-pass write test with badblocks should take about 3 days, |
| 38 |
if I do not err in my calculations. |
| 39 |
|
| 40 |
The same amount of time should take formatting it with |
| 41 |
# mke2fs -cc |
| 42 |
But I have not tried that so far. |

My WDC WD15EADS (it is Green) already works (hosting my /home) |
| 52 |
for more than 10 years and the systems reports that it is still ok. |

(I work at this computer from 6 to 8 hours daily.) |
