btw this is where apple's time machine comes in handy. it's like a fully automated virtual tape device plus backup client, so you can use online storage as if it were offline, and just not think about it too much you can recreate the same setup using bacula client/server, but it's a lot more effort

Notorious b.s.d. posted:hard drives are not meant to be used as offline devices Well now I have like 4 8tb drives and a couple 4tb drives stacked away on a shelf with my precious files on it. What would I do with them? Stack all 8 of em in some sort of enclosure? I'd use Time Machine but I don't use any Apple stuff at all except for an OG iPad Pro Notorious b.s.d. posted:after you hit the error on linux, check `dmesg | tail -n100` (the last 100 lines of the kernel ring buffer) to find out exactly what poo poo itself Thanks for this but I gave up on trying to solve this in Linux. It just kept duplicating the crashing issue to any new drives. Definitely one of the more unique computer problems I've ever had. What worked for me finally was following the advice in this thread and disabling automounting of new hard drives via disk part in Windows. When I plugged in the hosed up drive (either the original one or the newly created one in Linux), it stopped crashing Windows. I ran check disk on the Linux-made drive and it deleted literally everything except some DS ROMs lol. I've never had check disk do that before. So I took the original drive and scanned it with GetDataBack and all it found was the DS ROMS. I hosed with some options that I don't really recall in GetDataBack and it did some deep scan which took almost two days. It found every single solitary file and dumped all of them to another 8tb drive I had. So far, I can't detect if any of them are corrupted in any way (I've had GetDataBack "find" deleted videos and pics for me in the past but most of the time they can't be opened). I still to this day have no clue what happened to this drive. I'm guessing repeat power failures while it was in use corrupted it somehow. But I have no idea how or why GetDataBack was able to get it back. It definitely wasn't a partition issue or anything like that. The other four hard drives were all revived by soldering a small wire across a 5v fuse on the reverse side of the PCBs of all four hard drives' boards. Luckily I'm one of those OCD nuts with old video game picture quality and I've been modding game consoles since my SNES Mini in 2003 didn't have S-Video wired up.

windows 10 has this thing called File History that you can point at an internal drive, external drive, or nas it's like a really lovely version of time machine but it works. the lovely part is if you ever need to do a full restore from it google explicit instructions b/c it's honestly kinda confusing alternatively just robocopy your poo poo every so often vOv

Tape media has similar problems to hard drives, the medium is very stable, but the tape drives themselves have lots of moving parts with belts, rollers, bearings, etc. Way more than a hard drive in fact. Those dry up over time just the same if not worse. And since drive technology changes over the years, you need to keep the drive for reading the backups with the backups themselves, lest there not be a compatible reader available in the future. So you're still needing to store a mechanical device with the backups that is prone to aging and failure. The difference of course is that you only need to have one working drive to be able to read all of your backups, whereas with hard drives each and every drive can fail, making those files lost. (Barring things like swapping platters and such.) Then there is the fact that after a couple of decades the interface standard, encodings, file formats, etc will fall out of use and won't be supported by modern hardware and/or software anyway. The only solution really so far is to keep "refreshing" your backups, transferring them to newer media every decade or so. When all the devices still work, and the older technology is still supported by modern machines.

I feel like this thread or its predecessors was where someone mentioned pfatt, a pfsense script that used netgraph to bypass the AT&T provided CPE so you could use your own hardware from the ONT. Well it's 2020 now and apparently you can downgrade the firmware on the AT&T CPE and throw some query params at it, get a shell, and extract the device's certs so you can use wpa_supplicant to do EAP directly and get that stupid AT&T box off of your network.

In windows you can set your display settings so that the edges “connecting” your monitors touch anywhere you like. so you can set the monitors in such a way that only the corners are touching which should prevent you from rolling over by accident I hope that made sense

So, following instructions from the laptop vendor's support, I reinstalled Windows. The pen is not shown in Device Manager at all, not even as a hidden device. There are no drivers available for the pen at the support site. It is an Acer Active Stylus, so the manufacturer's own solution and not eg. something by Wacom. How do I get Windows to detect & install the pen as a HID?
