<div dir="ltr"><div>Well, if it weren't for the fact that you swapped the Kingston SSDs out for Intel SSDs and still experienced the same problem inside of a month, I'd have thought that perhaps the Kingston SSDs had failed. I had a bad rash of too-short-lived SSDs for a year or so period that spanned manufacturers and form factors (2.5" and M.2)...implying that there was perhaps a bad run of chips from a chip manufacturer that was sold to more than one SSD manufacturer. However, assuming the May 2018 Kingstons were replaced with brand-new Intel SSDs than then also experienced the same problem, I'd say you've probably mostly-ruled out failed SSDs as the root cause of your problem.</div><div><br></div><div>One thing further you may can/should do is to try to definitively determine if the SSDs are failed. One thing you can try is to take a "failed" SSD and attach it to a known-working computer either via a SATA->USB adapter (or M.2->USB adapter...whatever your formfactor/interface is) and see if you can reliably still access the drives without trying to boot from them. (You could also simply put them on a secondary SATA (or M.2) interface in the working computer.) If you're able to access the files from the "failed" SSDs, then probably your SSDs are actually fine and you can start looking elsewhere:</div><div><br></div><div>"Elsewhere" could perhaps be software (malware?) that's corrupting the boot loader saved on the SSDs or maybe something that's corrupting the firmware/UEFI info. If you're re-installing your OS from scratch each time you put a new SSD in a computer, then it's <i>probably</i> not software causing the problem (unless the bad software is getting re-installed each time) and so maybe you're looking at a firmware/hardware problem. Maybe verify that your boot order is correct in the firmware. Check to see if the SSD, once it has "failed", is still detectable by the firmware. (If not, is the interface/cable you're using on the motherboard marginal...maybe try a different cable/interface if you can.)</div><div><br></div><div>If this were one machine, I'd look harder at the hardware, but it's suspicious that several computers have experienced the same failure at exact the same time. That implies some sort of external <u>event</u> occurred that is the root cause of the problem. (ie: a power surge damaging multiple computers in an identical way...that's probably a stretch, or malware spreading and infecting multiple computers near simultaneously, etc...some specific cause than can span multiple computers at the same time.) If it were just a bad run of hardware, they might fail within a small time frame, but I wouldn't expect three SSDes or motherboards to fail in the same way <u>on the same day or even a day or two apart</u>, even if purchased at the same time. (It could fail identically over a period of a few months or weeks, but the same day/week would be very unlikely with a bad run of hardware.)</div><div><br></div><div>Nothing very obvious with this type of problem as you described it...You're just left with trying to use clean troubleshooting steps: Keep cutting the problem in half until you have your answer. Is it software or hardware? If you can definitively rule out software (perhaps boot record corruption in this case), then you can focus on hardware/firmware...so does the problem stay with the motherboard, or does it follow the SSD? If you can rule out the SSD's, then you can focus on the motherboard...etc.</div><div><br></div><div>HTH a tiny bit,</div><div>Good luck!</div><div><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div>______________________________<br><b>Chad Neeper</b><br><font size="1">Senior Systems Engineer</font><br><br><b>Level 9 Networks</b><br><font size="1">740-548-8070 (voice)<br>866-214-6607 (fax)</font><br><br><font size="1"><i>Full IT/Computer consulting services -- Specialized in public libraries</i></font><br></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Sep 9, 2019 at 10:28 AM Lynne Welch via OPLINTECH <<a href="mailto:oplintech@lists.oplin.org">oplintech@lists.oplin.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="font-size:10pt;font-family:Verdana,Geneva,sans-serif">
<p>Hello colleagues,</p>
<p>We have 5 HP Pro 3500 Series MT desktop units used by the public. All bought at the same time with the same specs from the same people. In April or May 2018 we replaced the hard drives with Kingston SSDs so they would be faster.</p>
<p>Early in August 2019 we came in one day and OPLIN 1 and 2 were just fine, but 3, 4, and 5 showed "Cannot boot". I've attached a screenshot.</p>
<p>New Kingston SSDs did not solve the problem, so we replaced them with Intel SSDs in OPLIN 3 and 4 last Thursday. We re-installed the original hard drive in OPLIN 5 since we could only get 2 Intel SSDs.</p>
<p>Today OPLINs 3 and 4 show the same "cannot boot" error, while 1 and 2 (on the original Kingston SSDs), and 5 (on the original harddrive it came with) are humming along just fine. Argh!</p>
<p>We are at our wit's end, especially with school starting back up. Any suggestions?</p>
<p>Thanks,</p>
<p>Lynne</p>
