Smart Check 通过，Short DST Failed(Smart Check passed, Short DST Failed)表明硬盘驱动器有问题。计算机的一个巧妙之处是它们能够进行自我监控。将要研究的一个进行自我监控的组件是硬盘(Hard) 驱动器(Drive)。硬盘(Hard)驱动器使用SMART（自我监控、分析和报告技术(Self-Monitoring, Analysis, and Reporting Technology)）来衡量其可靠性并查看它们是否出现故障。
让我们了解什么是DST(SMART)失败错误。
什么是SMART
SMART（自我监控(Self-Monitoring)、分析(Analysis)和报告技术(Reporting Technology)）被硬盘驱动器用来衡量它们的可靠性并查看它们是否出现故障。SMART功能内置于每个硬盘驱动器中，并测试其性能的各个方面，以确保其性能达到所需的标准。SMART将检查从Read/Write速度、错误率到内部温度等方面。每次计算机启动时都会执行一次短磁盘自检(Self Test)。
什么是夏令时
DST 表示磁盘自检，(Disk Self Test, )硬盘驱动器可以执行两种类型的自检。
每当您的硬盘驱动器执行短磁盘自检(Short Disk Self Test)时，它都会快速检查其各种组件。简短的DST只关注主要部件，如Read/Write头、ROM、控制板、盘片和电机。自检可确保这些主要组件正常运行，如果其中任何一个不正常，将返回警告消息。此检查只需要几分钟，在此期间您仍然可以使用硬盘。
在 Long/Extended Disk Self Test中，主要组件将与盘片上的数据一起进行测试。如果Long DST在磁盘上发现损坏或损坏的区域，它将尝试重新分配和重新映射损坏的部分。这将确保硬盘驱动器不会再次遇到这些坏区域。在Long DST期间，硬盘驱动器在测试完成之前不能使用。
短 DST 和长DST都是非破坏性测试，它们不会损坏或更改硬盘驱动器上的日期。
当硬盘驱动器出现长或短DST时，这意味着它不再能够正常运行。最好备份数据并更换硬盘。根据DST错误的原因，可能可以恢复数据(recover data)。可能会出现DST错误，然后硬盘驱动器立即死机，或者在几周、几个月甚至一年之后。但是，最好在DST错误的第一个迹象时备份数据。这很关键，因为您不知道硬盘驱动器可以工作多长时间。
智能检查(Smart Check)通过，短 DST(Short DST)失败
每个硬盘在启动时都会做一个短 DST(Short DST)。您的 HP 电脑内置了一个诊断工具，该工具将在启动时运行。当测试返回错误时，如果您尚未备份重要数据，最好立即备份。当组件出现故障时，您不能总是依赖计算机发回错误消息，因此最好定期进行磁盘扫描并备份数据。可能有也可能没有错误消息，指出存在短 DST(Short DST)故障，但有迹象表明这可能即将发生。这里有几件事可能意味着可能即将发生短暂的DST故障。
- 计算机速度变慢并且反应迟钝
- 电脑不断重启，硬盘灯间歇性闪烁
- 计算机硬盘驱动器无法启动，您会看到一个空白屏幕。
请注意，这些迹象也可能与其他问题有关，因此请逐步检查以排除其他潜在问题。
可以修复Short DST Failed 错误吗？
通常，当出现短暂的DST错误时，无法判断硬盘驱动器何时最终会出现故障。最好始终备份数据以确保其安全，以防硬盘驱动器停止工作。在短暂的DST(DST)失败错误的情况下，可以做一些事情。
- 主动
- 更新驱动程序
- 物理检查硬盘
- 更换硬盘
1]积极主动
最好的行动是在事件发生之前采取行动。定期备份(Backup)数据，以尽量减少硬盘发生故障(hard drive failure)时的损失。可以使用本地备份，例如外部硬盘驱动器。一些外置硬盘驱动器甚至提供加密技术来保证数据安全。
您也可以选择使用Microsoft One Drive将数据备份到云端。使用Microsoft One Drive的优势在于数据可以在世界任何地方访问。没有法律禁止同时使用这两种备份选项。最好将数据放在多个地方，以防万一失败。
2]更新驱动程序
更新硬盘驱动器的驱动程序以确保它是最新的(make sure it is up to date)。这将有助于消除导致错误原因的过时驱动程序的可能性。
单击开始(Click Start)并键入设备管理器(Device Manager)，单击箭头展开磁盘驱动器，右键单击驱动器，然后单击更新驱动程序(Update Driver)。
单击自动搜索驱动程序(Click search automatically for driver)。这将更新您的硬盘驱动器的驱动程序，或者它会告诉您安装了最新的驱动程序。
3]物理检查硬盘驱动器
短DST失败错误可能是由与硬盘驱动器和计算机之间的连接有关的其他原因引起的。如果连接电缆松动或性能下降，这可能会导致性能问题，因为数据无法正确流入和流出硬盘。重新连接或更换电缆可能会修复短暂的DST故障错误。
检查另一台计算机中的硬盘驱动器也可能会有所帮助，这在台式计算机上可能会更好。这将有两个重要目的，这将显示硬盘驱动器是否正常工作，如果正常工作，则可能表明计算机可能存在其他问题。如果硬盘驱动器在第二台计算机上工作，连接到另一台计算机也有助于备份重要数据。在某些情况下，可以将硬盘驱动器放在外部外壳中，然后通过USB端口连接到另一台计算机。如果硬盘驱动器确实出现，这将允许恢复数据。
4]更换硬盘
可能是时候面对现实，更换硬盘以最大程度地减少数据丢失了。保留硬盘驱动器可能会给人一种虚假的希望感，然后硬盘驱动器突然出现故障，数据丢失。简短的DST失败错误不会给出硬盘驱动器何时发生故障的时间表，它可能是几天、几周、几个月或几年。保持硬盘驱动器处于使用状态是一种风险，您必须愿意承担知道后果的风险。更换硬盘驱动器将使您高枕无忧，因为无需担心硬盘驱动器突然死机。
您可以将硬盘驱动器更换为普通硬盘驱动器，也可以选择速度更快的固态驱动器。评估情况，看看是否值得更换硬盘驱动器或只是购买一台新电脑。看看计算机是否已经完成了它的时间并在需要时更换它。如果计算机较旧并且其他组件可能出现故障，这可能是一个更好的选择。
结论
每当出现短暂的DST故障时，最好从排除过程开始。先做最简单的事情。
更新(Update)硬盘驱动器，进行物理检查，例如检查连接电缆和插座，然后检查另一台计算机上的硬盘驱动器。最好定期备份您的数据，(backup your data regularly)以尽量减少数据丢失。扫描磁盘以查找错误总是明智的，因为硬盘驱动器可能会在没有DST故障消息的情况下突然死机。
Fix Smart Check passed, Short DST Failed error on HP computer
Smart Check passed, Short DST Failed is a sign that there is something wrong with the hard drive. One neat thing about computers is their ability to do self-monitoring. One component that will be looked at that does self-monitoring is the Hard Drive. Hard drives use S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) to measure their reliability and see if they are failing.
Let us get SMART on what is DST failure errors.
What is S.M.A.R.T
S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) is used by hard drives to measure their reliability and see if they are failing. The S.M.A.R.T capability is built into every hard drive and tests every aspect of its performance to make sure it is performing up to the required standards. S.M.A.R.T will check on aspects from Read/Write speed, error rates to the internal temperature. Each time the computer starts a Short Disk Self Test is performed.
What is DST
DST means Disk Self Test, there are two types of self-tests that a hard drive can perform.
- Short Disk Self Test
- Long Disk Self Test
Whenever your hard drive performs a Short Disk Self Test, it quickly checks its various components. The short DST only focuses on the major components, such as the Read/Write head, ROM, control board, platter, and motor. The self-test makes sure that these major components are functioning properly and will return a warning message if any of them are not. This check only takes a few minutes, during which you can still use the hard drive.
In a Long/Extended Disk Self Test, the major components will be tested along with the data on the platter. If the Long DST discovers damaged or corrupt areas on the disk, it will try to reallocate and remap the damaged portions. This would ensure the hard drive will not run into these bad areas again. During the Long DST, the hard drive cannot be used until the test is finished.
Both short and Long DST are non-destructive tests, they will not damage or alter the date on the hard drive.
When a hard drive fails a long or a short DST, it means that it is no longer able to function properly. It is best to backup data and gets a replacement hard drive. Depending on the cause of the DST error, it might be possible to recover data. There may be DST error and then the hard drive dies immediately, or after a few weeks, months, or even year. However, it is best to backup data at the first sign of DST error. This is critical because you do not know how long the hard drive will work.
Smart Check passed, Short DST Failed
Every hard drive will do a Short DST upon startup. Your HP computer has a diagnostic tool built right in that will run at startup. When the test returns an error, it is best to backup important data right away if you were not doing so already. You cannot always depend on your computer to send back an error message when components are failing, so it is best to regularly do disc scans and back up data. There may or may not be an error message stating that there is a Short DST failure but there are signs that this may be near. Here are a few things that could mean that there may be an impending short DST failure.
- The computer slows down and is sluggish
- The computer restarts constantly, and the hard drive light flashes intermittently
- The computer hard drive won’t boot and you get a blank screen.
Note that these signs may also be linked to other problems so do a step by step check to rule out other potential problems.
Can Short DST Failed error be fixed?
Usually, when there is a short DST error, there is no way to tell when the hard drive will eventually fail. It is best to always backup data to keep it safe in case the hard drive stops working. There are a few things that can be done in the case of a short DST fail error.
- Be proactive
- Update driver
- Physically check hard drive
- Replace hard drive
1] Be proactive
The best action is to act before the event occurs. Backup data regularly to minimize the loss in the event of a hard drive failure. A local backup such as an external hard drive can be used. Some external hard drives even offer encryption technology to keep data safe.
You may also choose to make use of Microsoft One Drive to backup data to the cloud. The advantage of using Microsoft One Drive is that the data is accessible anywhere in the world. There is no law against using both backup options. It is better to have the data in multiple places just in case one fails.
2] Update driver
Update the hard drive’s driver to make sure it is up to date. This will help to eliminate the possibility than an outdated driver is the cause of the error.
Click Start and type Device Manager, click the arrow to expand disk drives, right-click on your drive, and click Update Driver.
Click search automatically for driver. This will update the driver for your hard drive, or it will tell you that you have the latest driver installed.
3] Physically check the hard drive
Short DST fail error can be caused by other reasons that have to do with the connection between your hard drive and the computer. If the connecting cable is loose or degraded, this could result in performance issues because data cannot flow properly to and from the hard drive. Reconnecting or replacing the cable may fix a short DST failure error.
It may also help to check the hard drive in another computer, this may be better on a desktop computer. This will serve two important purposes, this will show if the hard drive is working, and if it does it could be showing that the computer might have other problems. Connecting to another computer could also help with the backup of important data if the hard drive does work on the second computer. In some cases, the hard drive can be placed in an external enclosure and then be connected to another computer via USB port. This will allow for the recovery of data if the hard drive does come up.
4] Replace the hard drive
It may be time to face reality and replace the hard drive to minimize the loss of data. Keeping the hard drive in might give a false sense of hope and then the hard drive fails suddenly, and data is lost. A short DST fail error does not give a timeline when the hard drive will fail, it could be days, weeks, months, or years. Keeping the hard drive in use is a risk that you have to be willing to take knowing the consequences. Replacing the hard drive will offer peace of mind because there is no fear of sudden hard drive death.
You can change the hard drive for a regular hard drive or go for a solid-state drive which is much faster. Evaluate the situation to see if it is worth changing the hard drive or just getting a new computer. See if the computer has done its time and replace it if needed. This might be a better option if the computer is old and there is a possibility of other components failing.
Conclusion
Whenever there is a short DST failure, it is best to start with a process of elimination. Do the easiest things first.
Update hard drive driver, do physical checks such as check connection cables and sockets, then check hard drive on another computer. It is always best to backup your data regularly to minimize data loss. It is always wise to scan the disk for errors as a hard drive may die suddenly without a DST failure message.
