The problem I was referring to was for drives LARGER than 2TB (I think |
| 30 |
the real limit hits somewhere around 2.1 or 2.2TB). So if your drives |
| 31 |
are 2TB then I don't think it's that problem. |

I use a 2TB external USB drive myself (LaCie brand, with a pair of |
| 34 |
spanned 1TB Samsung disks inside), formatted as ext4, and it works |
| 35 |
fine. However, that was not always the case. I had to replace the USB |
| 36 |
cable after I suffered a lot of corruption and random USB disconnects. |
| 37 |
Later on, the drive started going offline and making the click of |
| 38 |
death, and eventually failed to start up. It turned out to be a faulty |
| 39 |
power supply. They sent me a replacement free of charge, despite the |
| 40 |
drive being out of warranty, and it worked perfectly fine with the new |
| 41 |
power supply. And it has worked fine ever since. |
