May be. But I have just finished testing its first 41 GB with # badblocks -sw -b4096 Three passes with different write patterns took about 2 hours 10 minutes, that is about 33 minutes per pass. So, the full one-pass write test with badblocks should take about 3 days, if I do not err in my calculations. The same amount of time should take formatting it with # mke2fs -cc But I have not tried that so far. > Testing the drive with dd and copying files to the > drive is very slow. Don't touch "Green Drives". > They die like flies. What do you mean by this? My WDC WD15EADS (it is Green) already works (hosting my /home) 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.)
