What is a Short DST Check?
A short DST (Drive Self Test) check is a diagnostic test run on some HP hard drives to quickly check the drive’s health status. DSTs are built-in self-tests that exercise and stress different aspects of the hard drive to identify potential issues or failures.
The short DST specifically checks the electrical and mechanical components of the drive. It performs a quick scan to detect any obvious defects or problems that would prevent the drive from working properly. This short test typically takes 2 minutes or less to run.
The main purpose of the short DST is to provide a fast way to determine if a hard drive has completely failed or has internal damage. It can identify issues like a mechanical failure, electrical failure, or firmware problem. The short test helps diagnose drive problems efficiently compared to longer, more comprehensive scans.
If the short DST check passes, the hard drive’s main functionality is intact. But if it fails, that signals there is a fundamental problem with the drive that prevents it from working correctly. Failed short DSTs usually require drive replacement or professional data recovery services.
Causes of Short DST Fail
There are a few common causes of a short DST failure on HP hard drives:
Bad sectors – If areas of the hard drive platters get physically damaged and develop bad sectors, this can lead to read/write errors that cause a short DST failure. Bad sectors often indicate the early stages of a mechanical failure.
Mechanical failure – Issues with the physical hard drive components like the read/write heads, motor, or platters can prevent the drive from reading data correctly. This will show up as a short DST failure.
Firmware bugs – Sometimes bugs in the drive’s firmware can cause incorrect results or failures during short DST checks, even with no hardware problems. HP has released firmware updates in the past to address short DST errors.

Symptoms of Short DST Failure
When a hard drive is experiencing issues that lead to a short DST failure, there are several common symptoms that may arise. The most severe symptoms indicate the hard drive is failing and data loss or corruption has occurred or will likely occur soon.
One of the most noticeable symptoms is complete system freezing or the inability to boot into the operating system. This occurs because critical boot files and drive sectors are becoming inaccessible due to deterioration of the physical drive. If rebooting does not resolve the issue, it indicates a serious problem with the hard drive itself rather than a software or OS issue.
Frequent blue screens or crashes during normal use and operations are another indicator of short DST failure. As more sectors fail and data corruption spreads, the instability will lead to crashes and error messages. The system may run slower as well due to excessive bad sector remapping and error correction.
Finally, users may encounter file read/write errors, inaccessible files and folders, and the inability to save new data. This occurs when data loss and corruption has already occurred within files stored on the faulty sectors of the drive. Valuable user data can be permanently lost if the damage is significant.
In summary, freezing, crashes, read/write errors, and an inability to boot clearly indicate a hard drive that is deteriorating and failing short DST checks. Users should immediately backup data and replace the faulty drive before catastrophic data loss ensues.
Affected HP Hard Drive Models
HP laptops and desktops use a variety of hard drive models that can be impacted by short DST failures. Some of the common HP hard drive models affected include:
- Hitachi Travelstar 5K750
- Western Digital Scorpio Blue
- Seagate Momentus Thin
- Toshiba MQ01ABD050
- HGST Travelstar Z5K500
These 2.5 inch hard drive models from major manufacturers like Hitachi, Western Digital, Seagate, Toshiba, and HGST are commonly used across various HP Pavilion, Envy, Spectre, EliteBook, ZBook, ProBook, and other laptop product lines. While primarily seen in laptops, some desktop models like the HP Pavilion Slimline may also use these hard drives and encounter short DST failures.
The issues seem most prevalent in hard drives from 2012-2015, which aligns with the manufacturing timeframes for many of the models listed above. However, HP laptops and desktops with hard drives from other manufacturers and years may also occasionally exhibit short DST fails.
Fixing a Failing Short DST
If your hard drive is failing the short DST, there are a few options to try and repair or replace the drive:
Run the full diagnostic test – Sometimes running the more comprehensive long DST can reveal different results than the quick short DST. Use the hard drive manufacturer’s tools like SeaTools for Seagate drives.
Update drivers – Outdated disk drivers can sometimes cause short DST failures. Update your HDD controller drivers and SATA drivers to see if it resolves the issue.
Replace the hard drive – If diagnostics continue to show a short DST failure, the hard drive is likely faulty and needs to be replaced. Check your warranty status and contact the manufacturer about a replacement if still covered.
Data recovery – With any drive replacement, your data is at risk. Be sure to backup important files before swapping out the hard drive. Data recovery services may be able to rescue data from a failing drive.
Some key things to remember during short DST failures are to stop using the drive immediately to avoid further data loss. Also refrain from running intensive programs like chkdsk, which could cause more damage.
Preventing Short DST Failures
While Short DST failures can happen unexpectedly, there are some steps you can take to help prevent them:
Perform regular backups of your data. Backing up important files and system images allows you to restore your system if a hard drive failure occurs. Consider using backup software or services that perform automatic, scheduled backups.[1]
Consider upgrading to an SSD instead of an HDD. SSDs have no moving parts, making them less susceptible to mechanical failure over time. However, SSDs can still experience failures, so backups are still recommended.[2]
Monitor your hard drive’s SMART data and attributes. SMART provides insight into the drive’s overall health and can warn of potential issues before failure occurs. Use tools like CrystalDiskInfo to check SMART regularly.[3]
Long vs Short DST Comparison
The main differences between long and short DST checks are the duration and scope of the testing. A short DST typically takes just a couple of minutes, while a long DST can take several hours to complete.
In terms of scope, a short DST performs a quick check of the hard drive’s basic functioning and components. It verifies that the drive can spin up, the heads can move, and basic communication is working. A long DST is much more thorough and comprehensive. It does a full scan of the drive’s surface, mapping out bad sectors and checking read/write functionality across the entire disk (Reference: https://www.gillware.com/hard-drive-data-recovery/hard-disk-short-dst-failed/).
So in summary, a short DST is a quick test of the drive’s critical components while a long DST fully examines the health of the entire hard disk. A short DST failure suggests a hardware problem, while a long DST failure confirms more serious issues.
Limitations of Short DST
While the short DST check is quick and convenient, it has some notable limitations:
The short DST is not comprehensive – it only checks a few critical components of the hard drive. So it can miss problems that a more extensive test would detect. This means a hard drive can pass the short DST but still have faults that impact performance and reliability.
Short DST checks are also prone to false passes. Since the test is so brief, it may not uncover issues that take time to manifest. Intermittent or latent defects often go unnoticed. So a hard drive can pass a short DST check but develop problems soon after.
Due to these limitations, workarounds are often needed after a short DST. Users may have to resort to trying a long DST, using advanced diagnostics, or replacing the hard drive. So while a short DST pass seems promising, it does not guarantee the hard drive is healthy.
In summary, the brevity of the short DST means it lacks the comprehensiveness of a long DST. This can lead to both false passes and undiscovered faults. So the short DST has clear constraints as a diagnostic tool.
Alternatives to Short DST
While the short DST check is a quick way to identify potential issues with an HP hard drive, there are some alternatives that can provide more comprehensive testing and repair capabilities:
Long DST
The long DST check is a more in-depth version of the short DST test that scans the entire hard drive surface for defects. It can identify problems that the short DST may miss. However, the long DST takes much longer to complete (source).
Full Disk Scans
Tools like CHKDSK in Windows or fsck in Linux can scan the full file system for errors and attempt repairs. These examine the logical file system structure rather than the physical drive surface, complementing the DST checks.
Manufacturer Tools
HP provides the Drive Protection System Utility for more comprehensive drive testing and maintenance. Other manufacturers offer similar tools to scan drives and check SMART status. These go beyond the built-in short DST.
Overall, while the short DST delivers a quick check, other more thorough options can help better identify or resolve hard drive issues.
The Future of Short DST Checks
As hard drive technologies continue to advance, the future of the short DST check is uncertain. While the short DST check has been relied on for many years to test drive reliability, new developments may replace or improve upon it.
According to a Reddit discussion on r/Hewlett_Packard, while the short DST check is useful for initial drive testing, more comprehensive long DST checks may become standard for fully evaluating drive health and reliability [1]. Long DST checks stress test drives more rigorously and can detect issues that short DST may miss.
Industry experts predict machine learning and AI will be leveraged to analyze drive telemetry data and predict failures more accurately than DST checks. As explained by DiskInternals, AI-based tools could detect failure patterns and alert users to replace drives before they actually fail.
Overall, while the short DST check still serves a purpose for basic drive verification, future advancements in AI and long-term drive testing may provide more robust alternatives for evaluating drive health.
