Some 'new to me' drives that are now living out their life in an old eol nas unit. All this hardware was destined to be trashed, but now lives on as a network scratch drive. :)

It can join the other seagate I have that seems to be of the same family. :D That is just an awesome POH and one heck of a drive.

These old Seagates are amazing, especially the .7, .9, .10, .14 series units.
The .14 series, if it is the version with only one plate, are usually very reliable, those that equip 2 disks are no longer so reliable.
There are also the 1TB ones (1SB102 and 2EP102) (Both are series 14) that are coming out very well.

You know, I don't know why there isn't a 'data safe' series of drives that uses only a few platters and writes the same info in different places on the drive for an effective 'mirror' on a drive itself. This could decrease the error rate by probably one more order of magnitude (1 in 10^7 vs 10^6 or 10^5) if not multiple orders and be really valuable in situations where there simply cannot be data loss.

I did have to break out my SUPER DUPER optical drive and install Windows 7 32bit, as that is the last version of the 2940UW controller driver.
My motherboard won't boot from a USB Thumb drive. It will boot from all kinds of USB devices, Zip, Floppy, HDD, CD, but not a thumbdrive for some reason.

Wow. I had no idea they made an optical drive that could read BluRay AND HDDVD discs. And presumably, DVD and CD as well.

Doesn't make sense because some hard drive problems are complete failures. Issues with the electronics and firmware can go from working to not very fast. If a head crashes into a platter that can get real bad real fast, too. Better to mirror to a separate device for real time protection (even better if that separate device isn't from the same batch, with the same firmware, and the same power on time; lots of stories of firmware bugs resulting in dead drives when a power on counter rolls over; other more elusive firmware errors are likely to hit both drives if the access patterns are nearly identicial), and back up to a far off location for long term protection.

True, but I can imagine certain cases where an individual 'hardened' drive is easy to manufacture and pretty simple in logic like the spare sectors on enterprise SSDs, except actively using them to store redundant data. My thought is that if a 1 platter drive is so reliable, a 2 platter doesn't change the design much, but could be used as a redundancy vs increase in capacity. I'm sure some of these use cases are covered by an SSD (like high shock environment), but then it almost makes sense to have something like a hybrid drive with a full SSD/hardened HD mirror on the drive.

Ya, that one read BD, HD DVD, DVD, and CD. Pretty cool drive. That is what I used in my HTPC back in the day since I was buying some HD-DVD's for cheap when Bluray won the format war.

I also had the HD-DVD drives for the Xbox 360. I bought 2 since they also worked on the PC and I wanted a backup to play my discs if one of them failed.

Nice! I think we should have a movie night at Zepher's--a bunch of movies it would be a hoot to watch with all of you. :D
 
My 500GB Seagate is still fighting, there is little left to reach 100,000 hours.
The other photo that marks 99,998h is my uncle's hard drive (Seagate 1BD142 (It's the same disk model as mine)), which already turned 100,000h last week.

I also have a Kingston V300 240gb, the first version which is also the best, I'm using it in potato pc right now,but there are not many hours, only 5521

What do you think you're doing that's resulting in such remarkable POH consistently?

Leaving them powered up. ;) Those 2TB drives were enterprise drives from a Sepaton disk-based backup system.

Thank you! I've doing this for years as well so maybe that will help my drives live some long lives too. :) The HGST/Hitachi 2TB drives are some of the most stout I've ever seen. I wonder what the record POH is for these? I guess time will tell since they have been on since shortly after they were made. :D

Right, those 2TB are in mirrors in a ZFS pool since I got them used with 6ish years on them already, as I've had them around 6ish years. The 8s are slowly getting replaced with 16s, I need to pick up the pace on that work.
 
Wow 6yrs and you put another 6 on them? Amazing. I have some that I bought brand new and they have some years on them (scared to check how many actually), but haven't had any issues except for one that failed under warranty a few years back.

What impresses me the most here is the no the hours, but the power on count--I think most drives die before that type of power cycling!
Click to expand...

Power saving features over the past 25k hours pretty much account for the majority of power on counts with this drive... but yes, it is like starting a car, 90% of the wear is on start up.

This drive only has redundant (3rd copy) backup data of some really old videos on it... so it really isn't hit much at all these days.. but it did get alot of use out of the first 50k hours in a raid 0 config. This drive outlasted the drive it was paired with, so will use it until it throws SMART errors.

Really amazing how it has stood the test of time. What was environmentally different than its twin in the raid 0 setup? I'd keep using the drive even after smart errors--bad sectors are still a thing that can be mapped out by a full format. Back in the day, you could even manually mark/unmark bad sectors, but that was expert level tinkering.

Sad news... my dear Seagate 1BD142 It's already starting to show signs of a catastrophic failure, it's held up like a champ for 5 years with me, I got it from a PC that was in the junkyard marking 57,000h, it's been working 24/7 as a torrent disk, until today, now the disk is working but I'm already considering removing it for fear that it will die completely and the server will freeze.
 
My oldest drive on my Unraid server are two 8tb Western digital drives (WDC_WD80EMAZ-00WJTA0_7JJ7XZ7C) they have 6 years of power on time, (These were shucked hard drives from an Easystore External hard drive.) I recently upgraded some to 20tb and 14tb drives. Eventually I will replace these two with 20TB drives.

LOL. 127028 Load cycles. That's destroying your hard drive. With 2500 online days, that's 50 load cycles a day. Quickest path to unnecessarily wear the drive.

That's nothing; I've got 1537684 on one of my drives, with 37051 hours, 4tb WD Blue model WD40EZRZ-00GXCB0. I had not realized the timeout defaulted to like 6 seconds or something. Also have a Seagate 4tb ST4000DM005-2DP166 with 675182 load cycles and 49188 hours. Same thing. And an 8tb WD WD80EAZZ-00BKLB0 with 636341 load cycles at 25169 hours; that one was stupid, cause I knew better when I got it, but didn't do anything to stop it. Whoopsie. My 4tb drives are in 'fun array' mode and were offline for a while before I figured I wanted to do that with them... the 10 tb current drives are around those hours too now, time to start thinking about replacing.

In my low end hosting box, I've got one drive with 120874 hours and 8 load cycles (power cycle count is 24); the other drive had to be replaced, so it's a young one with 22309 hours, 4 power cycles and 6 load cycles (but maybe it's older and the smart stats were wiped, I dunno). I'm not the first user on the old drive, but I might end up being the last :)

What's the big deal with the load cycles? Isn't that part of the hard drive design? From what I found online on stack exchange, "Load/Unload Cycle Count is how often the actuator arm is parked in the loading zone. The actuator arm holds the head which reads/writes to the disk. ...The head parking behavior is not usually controlled by your operating system. It is controlled by the disk drive itself. Each disk has it's own method of choosing when to park the arm. For example, a notebook drive might be a lot more aggressive in it's arm parking because it designed for a portable computer which might be jolted around a bit. An enterprise server drive, on the other hand, doesn't expect to be moved around as much (if at all!) and will also be expected to have the fastest possible access, so it won't park the arm as much."

It can be a weak part of the design. Used to be the parking ramps were expected to last 100k cycles max; modern desktop drives do a lot of parking though, so they beefed up ramps on many drives. If the ramps crack, that's probably going to be a rapid descent into an unusable drive, as the head arm is probably going to get tweaked and then the head might touch the platter and there's probably no warning either.
