Normally, there is not so many files in your USB stick, so the process is very quick and you can hardly feel it.īut if you have huge number of files in your USB stick, the process will be extremely slow and it will take a long time to boot into the menu. In reality, I suspect that the back-and-forth head actuator is less of a problem for new drives than the platter motor and drive circuits and logic electronics are, so I never got around to it.By default, Ventoy will search all the directories and subdirectories for the image files. With that in mind I've thought about making a image file of a typical badly-fragmented Windows installation, then I could write that to the disk and defrag it, to simulate heavy head travel. I set the number of rounds to a high number to make sure the tests continue for days.Ī slight problem with DBAN for this purpose is that it only does long linear writes, so something that excercises the head travel more (for example, a defragmenter working on a typical NTFS volume) would also test the head travel better. In my case I tend to use DBAN - a disk wiper that writes then verifies. Like all complex mechanical or electronic systems HDD have a reliability curve, plotting failures agaist time will show a classic "bathtub" curve - this article by Backblaze is good reading - in this case it compares their classic 2013 article with more recent data and discusses why the curve shape has changed over time.īackblaze 2021 datacentre HDD reliability If I hadn't checked the drive, 30 hours of use would have meant that the disk would be full of important data by then. I've even scalded a finger on the top (yes, the top) of a faulty drive case before - bearing problem meant that the whole drive case got abnormally hot after 30+ hours running. Because an obviously faulty drive will be, well, obvious during this time as it will throw up errors, noises or get very warm compared to others in the batch.īuilt-in drive SMART tests are relatively short term compared to a 4 or 5 day DBAN run. What I meant by "burning in" was simply running the disk under very prolonged heavy write/read loads (many hours or days long) after purchase in the hope that any mechnanical or electronic failures would occur before any important data was put on the disk. r/HomeNetworking - Simpler networking advice. ![]() r/pfsense - for all things pfsense ('nix firewall) Might be able to find things useful for a lab. r/hardwareswap - Used hardware, swap hardware. r/buildapcsales - For sales on building a PC r/linux - All flavors of Linux discussion & news - not for the faint of heart!
