I followed this thread, and couldn’t remember ever having the same issue. |
| 11 |
But today I was bitten: It’s a 3 TB external USB drive from Intenso. |
| 12 |
|
| 13 |
Yesterday I was in the middle of a backup (it’s my main backup drive), but I |
| 14 |
had to sleep and so sent the machine into standby. I had to start the PC |
| 15 |
again a few minutes later in order to unmount an sshfs of it on another |
| 16 |
machine, and sent it right back to sleep. |
| 17 |
|
| 18 |
Just now I switched the PC back on and the drive was gone and off (USB |
| 19 |
enclosures tend to spin down the drive when USB disconnects). So I pulled |
| 20 |
the USB cable and plugged it back in for the drive to start and be |
| 21 |
rediscovered. That worked and I resumed the backup, but this enclosure has |
| 22 |
the nasty habit of sometimes intermittently disconnecting on its own. |
| 23 |
|
| 24 |
Its device was not gone (it usually disconnects for a tiny moment and then |
| 25 |
comes back, probably a USB issue), so I just tried to open it again in |
| 26 |
Dolphin, which gave me: |
| 27 |
Error unlocking /dev/sdd1: Failed to activate device: File exists |

I don’t quite like this bad habit of the enclosure, but a 3 TB drive is a 3 |
| 48 |
TB drive. I just looked at smart to see how old it is, because it has only |
| 49 |
350 hours of power-on time, but it must be at least 5 years old. And |
| 50 |
smartctl tells me there is a firmware update available! (for Windows, Mac |
| 51 |
and—lo and behold—a bootable ISO, let’s hope it works with USB sticks). |
| 52 |
|
| 53 |
Perhaps this fixes the issue. Dale, maybe you should look for the same. |

Emacs is a great operating system, which only lacks a good editor. |
