Howdy, |

I finally bought a 8TB drive. It is used but they claim only a short |
4 |
duration. Still, I want to test it to be sure it is in grade A shape |
5 |
before putting a lot of data on it and depending on it. I am familiar |
6 |
with some tools already. I know about SMART but it is not always 100%. |
7 |
It seems to catch most problems but not all. I'm familiar with dd and |
8 |
writing all zeores or random to it to see if it can in fact write to all |
9 |
the parts of the drive but it is slow. It can take a long time to write |
10 |
and fill up a 8TB drive. Days maybe?? I googled and found a new tool |
11 |
but not sure how accurate it is since I've never used it before. The |
12 |
command is badblocks. It is installed on my system so I'm just curious |
13 |
as to what it will catch that others won't. Is it fast or slow like dd? |
14 |
|
15 |
I plan to run the SMART test anyway. It'll take several hours but I'd |
16 |
like to run some other test to catch errors that SMART may miss. If |
17 |
there is such a tool that does that. If you bought a used drive, what |
18 |
would you run other than the long version of SMART and its test? Would |
19 |
you spend the time to dd the whole drive? Would badblocks be a better |
20 |
tool? Is there another better tool for this? |
21 |
|
22 |
While I'm at it, when running dd, I have zero and random in /dev. Where |
23 |
does a person obtain a one? In other words, I can write all zeros, I |
24 |
can write all random but I can't write all ones since it isn't in /dev. |
25 |
Does that even exist? Can I create it myself somehow? Can I download |
26 |
it or install it somehow? I been curious about that for a good long |
27 |
while now. I just never remember to ask. |
28 |
|

When I add this 8TB drive to /home, I'll have 14TBs of space. If I |
30 |
leave the 3TB drive in instead of swapping it out, I could have about |
31 |
17TBs of space. O_O |

Thanks to all. |
