content: so, I bought eight SCSI-hard-disks, one doesn't even respond, the other seven have bad values when I query smartctlBut the seller insists that the records are acceptable ... and that I'm too picky and fussyso, let's see what I have used and seen on the consoleCode:# smartctl -a /dev/sda=== START OF INFORMATION SECTION ===Vendor: FUJITSUProduct: MAW3147NCRevision: 0104User Capacity: 147,086,327,808 bytes [147 GB]Logical block size: 512 bytesRotation Rate: 10025 rpmSerial number: DAA0P6801RGBDevice type: diskTransport protocol: Parallel SCSI (SPI-4)Local Time is: Fri May 27 21:33:04 2022 -00SMART support is: Available - device has SMART capability.SMART support is: EnabledTemperature Warning: Enabled=== START OF READ SMART DATA SECTION ===SMART Health Status: OKCurrent Drive Temperature: 35 CDrive Trip Temperature: 65 CManufactured in week 32 of year 2006Specified cycle count over device lifetime: 10000Accumulated start-stop cycles: 129Elements in grown defect list: 0Error counter log:Errors Corrected by Total Correction Gigabytes TotalECC rereads/ errors algorithm processed uncorrectedfast | delayed rewrites corrected invocations [10^9 bytes] errorsread: 0 28 0 0 0 24327.545 0write: 0 65 0 0 0 6244.290 0Non-medium error count: 142No self-tests have been loggedThis disk is considered "acceptable", but it's not as described, it's not "brand-new" because1) it has Non-medium error count > 1 (it means that the connection with the HBA has failed several times)2) it has processed 24 Terabyte of data3) probably it worked non-stop for months, 24 Terabyte of data with 129 power On/Off cyclesok? So, that's why I say "not brand new"This disk is the best of the whole lot, there are disks with terrible values, it may be acceptable (but not for the price I paid as "brand new") because it has ZERO "uncorrected errors" and ZERO "Elements in grown defect list".I consider these two values as an index of hardware failure, specifically how close to death are Disk read/write heads and platters.Am I wrong with this? What do you think?And, isn't there any other health testing software simpler and with explicit assessment of the state of health of the hard-disk for Paypal employees to understand?We are talking about 600 euro, and when you fill a claim and you open a dispute, Paypal wants to read documentationI used smartctl, part of thesmartmontoolsproject by Bruce Allen, Christian Franke.

content: Can confirm that the errors there are ECC and non medium which suggests problems with the HBA interface rather than the actual disk. Usually shitty firmware in the controller (HP I'm looking at you). They look fine to me from a "used disk" perspective.If you paid for them as new though, show paypal the power cycle count and say they have been turned on and off 129 times and that they are definitely not new.

content: You could also try this:smartctl -t short /dev/sdXWait until finished, then run smartctl -a again and thedisk run time should show up in the list of self-tests(NB: for some disks the hours will turn over at 65535).Update Nov 24th 2022:Just wiped some SAS drives, and the hours were stuck at65535 (both before and after wiping which took ~2 days).

content: They're clearly used and were advertised as new, no need to go farther, refund or replace time.

content: Shouldn't there be a count of power-on hours? SATA drives report that via smartctl.

content: If sold as brand new, I agree that I’d focus on the power cycle count (and hours where implemented) as the primary thrust of the argument.You could include the other data (TBW, etc), saying that it corroborates the drives as not brand new, but I’d try to keep one clear and obvious line of reasoning that any customer service person can read and understand as “yeah, this isn’t new”.

Just chuck it in a box, return it and sent it tracked. Ignore the seller comms entirely past telling them you are rejecting the goods.Notable NEVER buy anything consumable on eBay. It’s hard enough finding stuff on Amazon that isn’t used (just got an unsealed box Samsung 1TB evo plus this morning which was shipped from Amazon)

content: Quote from: bd139 on May 28, 2022, 05:19:46 pmFaster, larger, cheaper ... all true, but "better failure modes"?nahhhh, That's false with SSD!When an SSD fails it simply unplugs the plug, and it's gone with all data vanished; I told something similar in my topic about how poor reliable Flash is.It happened several times, the last one with an SSD disk on a MIPS laptop. In the end I gave up with its resurrection. Luckily, I had a backup on hands, I bought a new SSD disk from Amazon, and restored the image.When a SCSI drive fails ... well my Fujitsu-2GB has half of its list full of bad-blocks, but you can still load a kernel from it (yes, I am doing it ... well, it's the only 50pin SCSI disk I have here, at the moment), and its electronic circuits are still alive, it's just a problem with its platters. There are some bad blocks, but until the disk gets completely dead read/write heads, some bad blocks on platters don't affect the entire disk.With SSD I have always had bad luck, and on a couple of occasions all the data on the disk just vanished without any warning, and since then the disk has ZERO bytes of capacity, simply because some flash cells must be so damaged that the firmware has decided to pull the plug.Also, SSD sucks for RAID! For a real modern RAID, you have to buy NAS-SATA disks, specifically made for NAS. I opened a discussion here on the forum about that.

content: I disagree. I have data from over 2000 M2 SSDs used in production datacentres. They are at least two orders of magnitude more reliable than any mechanical disk. To the point we didn't actually impact storage reliability by not bothering with RAID. All redundancy was moved to logical machine level.As for the data disappearing I have never seen this. Not once. The only failure mode I have seen is it dropping into read only mode and that was after an insane TBW in a database server. But that's not an issue as there was a hot replica node.It of course depends what vendor you go for. Samsung 850 series and later Evo and Pro are fine as are Hitachi enterprise at least. Others, not so much.When you get to the TBW limit, replace it. I still have some of the exceeded TBW limit drives sitting around. They are fine for low reliability desktops (admin etc) and will probably last 3-4 years fine anyway.

content: I've seen one or two SSDs just up and vanish. It's not common these days, but it happens. I've had several fail with data corruption, most are after 2-3x their minimum TBW spec on very low cost drives, but I've seen a few lemons which are just plain faulty.. Ah yes, this Micron 1100 is one of those. I'd plug it in for the relevant stats but my USB adapter mysteriously karked it since I last needed it.I've also got some junk 'industrial' SSDs which just corrupt data in the background, and one which at a random point around a month of uptime, will just cease operating and require a power cycle - that was fun to pin.They seem mostly reliable, but the lower cost TLC and QLC units unsurprisingly have the higher failure rates IME, and I feel like a lot of them are firmware bugs than actual failure of the flash.

Assuming the kernel driver is working fine(2), if { HBA, cable, terminator } is the problem, then you should see increasing the "non medium error" value.It didn't happen with the new setup, hence the LVD-setup is fine; indeed, there are Fujitsu 10K rpm and Seagate 15K rpm disks that have perfectly passed all the "badblocks" tests (8 hours burn-in)Good point, howeverI will add a function to check the "non-medium error" value, in order to stop the test program if the value is seen to increase due to a bad physical SCSI configuration rather than due to a physical problem(1) with the disk under testing.(1) physical problems that I cannot test directly appear on the SCSI interface (hence to my testing program) like a communication/service disruptionworn out bearings -> read/write delayed correction or I/O abortworn out read/write heads -> read/write delayed corrections or I/O abortworn out brush less motor -> read/write delayed corrections or I/O abortworn out SCA connector -> wrong "tag phase reported" by the Linux kernel, disk not recognized, channel too noisy with too many retries (you have exactly this symptom if you use a bad cable, or a bad SCSI terminator)worn out electronic board with semi fried chips -> read/write delayed correction or I/O abortedit:Yup, I also have to write a function to monitor what the kernel complains for. Not yet done.(2) there are certain SCSI devices { CDROM, DVDRAM, MO, CD-Jbox, Tape{DDS, LDO, ...}, Scanner } that have SCSI-quirks, but I have never observed anything similar with SCSI disks.When a quirk arises, you see the kernel complain about phases and tags, with a lot of verbosity.If you don't see it, it's mostly 99.97% ok.

content: (What I really find annoying ... sATA/SAS and SCSI disks have a different way to respond to queries.When you simply want to read the serial number, you have to write two different piece of code, one for SCSI, one for sATA/SAS, the same applies for all the other variables you may want to see the value.SMARTtools, somehow, hides this under the same user interface)

content: I would throw something like the following in. That gives a chance for the vendor to actually test the disk before sending it out as it's probably not shipped from the manufacturer.Start-stop < 20corrected errors > 10uncorrected errors > 0grown defect list > 0Also to note I had some problems with actual HPE shipped SAS disks a couple of years back. The bearings seized after a few power cycles because they were stuck in a warehouse for half a decade. So storage is a consideration that needs to be made too. This put me right off any mechanical disks. In fact we have no mechanical disks at all now.

content: Quote from: bd139 on June 06, 2022, 12:54:19 pmI can consider this only by monitoring the phase-tag errors reported by the kernel.It only works for SCSI, it's not rock-science but it can somehow summarize some possible problems concerning the aging of components: oxidation of connector, or deterioration of electronics or heads.They can manifest in a sneaky way, not enough to cause a failure, but enough to cause too many retries, and in this case the kernel can report the problem via the SCSI verbose module.I will add soon

content: Worth pointing out active monitoring here.Last place I worked were using this:https://github.com/prometheus-community/smartctl_exporterThat then gets scraped by prometheus and alerted on by alertmanager. So when the DB SQL write master disks finally gave out, it'd autonomously wake up a troll who went and failed the node over and swapped the disk out.But they moved to EC2 / EBS where disk failure is Amazon's problem as it's a logical volume abstraction

content: DiTBho where did you get it from?Sorry I didn't see there were three pages already.I take pictures from the time I receive stuff to the testing. For something like that I'd start a surface scan with something like MHDD. I have a machine dedicated just for that for many years with a Scsi controller that works with it.https://hddguru.com/software/2005.10.02-MHDD/No I don't need to test it if there are signs of use but I do it to add weight to my argument of how used it is and I had a quite a few that were very well used so they can't come close to being described as "new". I expect it to help speed up a returns delivery form without any arguments and to eliminate having to hear the following claptrap excuses such as; well I have used it a little here and there, it's an ex demo etc...

content: Quote from: Ed.Kloonk on June 03, 2022, 10:51:18 amI still have an old RAID system like this intact and stored away. I got them in 2006. It is in a Coolermaster stacker case with a Tyan S2720 serverboard, Dual Xeon 3Ghz and 6gb ram with a Megaraid Enterprise 1600 (128mb battery backed up sdram) SCSI 2 with 6x 32gb Fujitsu 15000rpm drives in raid 5 and many cooling fans in the front to cool the drives. I got the board and controller second hand but I think I got the drives new old stock in 2007 for £30 each. I had some IDE drives in there too and was using it as a file server and run experiments on. Seemed quite reliable over the years I was using it. I did have two Seagate's in there both 36gb 15,000rpm as part of the raid at the beginning but they kept on going offline and causing all sorts of problems. When I tested the Seagate's individually they seem okay, when using them alone they are okay so I find that strange despite being the same specification. I stopped using it in 2017 when I brought a HP DL380 G5. That one 6x 72gb scsi3 drives in raid 5. Two of the drives were failing but I picked a couple up for £10 each.Just looking up the name on the email and according to his Linkedin Profile to the company he works it looks like he's a salesman:https://www.linkedin.com/in/damian-oduli%C5%84ski-1b0814135/QuoteI just found the sellers profile:https://www.ebay.co.uk/usr/apress24Not looking good.Other buyers have complained about being sold used as new:QuoteQuoteQuoteQuoteJust found their ebay account is in his name:https://www.ebay.co.uk/usr/apress24QuoteSo they have been going since 2011. Top seller rated. If it is true they have been sellingall used/damageddrives as brand new look at the amount of people they scammed so far, 2,570.Many people may not know what to look out of or understand if it is used and works and I have seen this sort of thing before and even sellers that go to lengths to have negative feedback removed.If you look at a few of their listings.I all I see are what looks like STOCK photos and I'd be wary when they do that.I'd only accept stock photos when I buying from somewhere like Ebuyer or Scan or somewhere I know is reputable and get them direct from the manufacturer.https://www.ebay.co.uk/sch/apress24/m.html?_nkw=&_armrs=1&_ipg=&_from=https://www.ebay.co.uk/itm/173483626670Wait a minute, looking at the decorations, the large stock photos and the affiliates.I suppose I could also get fooled into thinking I am getting old stock or stuff directly from the manufacturers with these people.

content: Quote from: MrMobodies on June 06, 2022, 08:24:55 pmYou were lucky. I paid 600 euros for 8 discs (~75 euro/disk) , and wasted another 32 euros to return them to the seller via UPS because I have a deadline to meet; I hope Paypal will refund me, and I have yet to find some good SCA disks.Moral for the story, although it is a very frustrating situation, the upside is that at least it motivated me to write a test program, which is a very educational experience, and very useful

They are usually quite quick as well I.e within a couple of days.If they work out they’re not making any money out of him after the refund or his bank doesn’t honour the refund transaction they will freeze him, close his account instantly and go “lol” and he’s out of business.
