I think modern drives run hotter, it's becoming an issue.
That does seem to be the case, yes.
Very possible. It just seems to be cycling that now. I'll probably hit the drive with a bulk eraser I've got somewhere in the basement before disposing of it. In the end, it was about 126 GB of space that was unreadable before it took the final crash.
Last time I had a disk go bad, with some bad sectors, I was able to recover an image of the disks partitions with dd; only one was really affected, and I had to do it with dd_rescue instead. On each bad sector it seemed as it tried to read, failed, maybe reset, then tried again. I think it tried 10 or 20 times for each sector, each attempt some seconds, and there were more than a few sectors bad. I left it running for half a day or more, but at the end I got an image I could run reiserfsck on it and recover some of the data.
And each attempt it did some clicks.
The rest of the disk had no problems at all, just some part of the surface gone bad. If the head or the electronics had been affected, nothing could have been recovered, I suppose. And the partitioning of the disk limited the damage to one partition, making the recovery of the rest very easy.
It seems that the problem is a bit more involved now; it's not even presenting on the USB bus the way it should, so I think the internal electronics are also toast. I could open it up and bypass them, but I also may have the option of returning the drive. Going to let it sit overnight powered off and see if that helps. I'm not real hopeful at this stage, but it is fortunate it was used mostly for backups and I still have most of the data in other locations.
Yeah, or at least twice the opportunity for a failure. New drive is a single drive, so hopefully that won't be an issue on it. A little concerned at how hot it seems to run, though.
Some enclosures are cooler than others. I like ones from "cooler master" named "xcraftlite". They have both esata and usb plugs, so that testing is easier connecting to the sata interface (which I still have to buy).
I heard of others with a little fan.
The new one actually does seem to be running cooler now - I had it laid down flat on top of the other drive (probably not a good idea in retrospect), now it's got plenty of ventilation on either side and it's not running as hot. So that's good news.
