My desktop or laptop hard drive may be defective, how can I test it? SMART errors reported by the BIOS and third-party utilities after Seatools passes all tests. Seagate USB External drive diagnostics. This is a very popular storage benchmarking tool because it’s versatile and can produce good results for just about everything from USB drives, to memory cards, RAMDisks, SSD drives and mechanical hard drives. CrystalDiskMark is very easy to operate too, just set the test size between 50MB and 4GB, the drive to test and the number of passes to run.
If you want to see how fast your network really is, or test the speed between two hard drives, then you need files to do it. Today we’ll tell you how to create “dummy” files so you can perform such tests.

Say you’ve installed a fast new solid state drive in your computer, and want to see how fast they really are. Or maybe you’ve finally upgrade your entire setup to gigabit ethernet or wireless AC, and you want to know how well it performs. Maybe you even want to compare the two.
The “theoretical” speeds on the box won’t really tell you how something performs in your home–you’ll need to test those transfer speeds yourself. To do so, you’ll need a file or files of the same size. Luckily, you can create dummy files of any size in Windows to serve this purpose–no extra software required.
How to Create Dummy Files on Windows
All you need is to open a command line and type a few quick commands. It works in any version of Windows, too. Press the “Windows + R” key combination to open the Run window and then type “cmd”. Press OK.
With a command prompt open, you can start creating dummy files to your heart’s content. To do this, we’re going to use Fsutil.exe, which is a built-in file system tool that allows you to perform file system operations from the command line.
Here is the syntax we want to use for creating dummy files:
The length of the file needs to be in bytes, so if you’re unsure how to convert a large file into bytes, then here are the values you need to enter to actually obtain the sizes you might want:
1 MB = 1048576 bytes
100 MB = 104857600 bytes
1 GB = 1073741824 bytes
10 GB = 10737418240 bytes
100 GB = 107374182400 bytes
1 TB = 1099511627776 bytes
So, this is what we’ll use in our syntax for creating a 1 gigabyte dummy file:
Just enter or copy-paste that text into your command line and hit “Enter” and your dummy file will be generated.
Once we create our new dummy file, (entering the true byte value of 1 gigabyte), we can right-click and select “Properties” to see its size, which is exactly 1 GB.
Of course, you might not be able to remember the exact byte size of one gigabtye or a terabtyte, but if you really need to, you can just refer to this article!
Now you can easily create dummy files of any size on your Windows PC–no more searching your computer for files of approximate sizes. With just a few key presses, you’ll be able to create exactly what you want and get the answers you need.
Testing Things Out
Once you’ve created a dummy file, you can use it to test out transfer speeds for anything ranging from a simple USB flash drive to your fancy new home network. Pcsx2 games download for pc.
Hard Disk Test
Testing transfer speeds with a dummy file is about as easy as you can imagine. For example, let’s say we want to test how long it takes to write a 10 gigabyte file to a flash drive over USB 2 versus USB 3. To do this, all we really need is a flash drive , a computer with both types of USB ports, and a stopwatch.
We’re going to use a 10GB file because we’re more likely to see a difference in transfer times with a larger file than with a smaller one. With smaller files, the difference will be significantly less noticeable.
First plug the flash drive into a USB 2 port (they are black, while USB 3 ports are blue), then drop the file onto the drive and start the stopwatch as you do.
As you can see from the following screenshots, the difference to copy a 10 GB file to a flash drive over a USB 2 connection versus a USB 3 connection is quite significant. On the left is the USB 2 time, and on the right is the USB 3. The USB 3 transfer is over two full minutes faster than USB 2.
You can repeat this test for any kind of transfers you desire. Feel free to test how long it takes to move a file from one computer on your network to another, to a cloud drive, or compare speeds between devices, such as how long it takes to transfer a file to one drive versus another.
There’s no limit to what you can test and time so if you’ve been wondering about the performance of your various devices, Internet connection, or network transfers, then create a dummy file and wonder no more.

One of the most important hardware components inside your computer is obviously the drive that holds the operating system. If you have Windows installed on a slow hard drive, it doesn’t matter how powerful the other components like CPU and memory are, the system will boot slower, load programs more slowly, and lag quite badly while multitasking.
This is a reason why high performance hard drives and especially SSD’s are so popular these days. It’s because upgrading just that one part can breath new life into a computer and make it feel a lot more snappy to use. The actual hard disk or SSD performance under Windows is determined by several factors so how do you know if your drive is performing well, needs tweaking or is even holding the system back?
Thankfully, the internet is full of websites to show you how well nearly every drive around can perform. Also, loads of programs are available that can give your hardware a performance test to see how well it’s doing. There are many paid suites around like PCMark or Passmark that can test the whole system, but here we list for you 10 free tools that are specifically designed for testing the performance of hard drives and SSD drives.All tools were tested on Windows 10 64-bit and are also compatible with Windows 7 and 8.

1. CrystalDiskMark
This is a very popular storage benchmarking tool because it’s versatile and can produce good results for just about everything from USB drives, to memory cards, RAMDisks, SSD drives and mechanical hard drives. CrystalDiskMark is very easy to operate too, just set the test size between 50MB and 4GB, the drive to test and the number of passes to run. More passes obviously should produce more accurate results.
Then click All to run a full test or any individual colored buttons below to run single tests. A useful extra option for SSD drives is whether to fill the test data randomly or with 0’s or 1’s. This will affect the results on drives with hardware compression such as those with Sandforce controllers. Portable, installer and custom skin versions are available.
Download CrystalDiskMark
2. ATTO Disk Benchmark
ATTO Disk Benchmark is a popular portable tool used by many hardware review websites and is also recommended by manufacturers such as Corsair to run speed tests on SSD drives. All the tests are sequential and are taken for read and write operations using block sizes of 512 bytes up to 64MB. A test file length of between 64KB and 32GB is also available, both are selectable from drop down menus.
Leaving Direct I/O enabled will rule out odd results due to any system caching. An I/O size of over a couple of Megabytes will produce virtually the same scores so probably isn’t needed for many users. Results can be saved out and loaded again at a later time. A look around the internet will likely find someone else who has posted ATTO results for similar hardware to your own.
Download ATTO Disk Benchmark (via Softpedia, the official site requires filling a form)
3. AS SSD Benchmark
AS SSD looks a bit like CrystalDiskMark and is designed primarily to benchmark SSD drives. It is another popular tool being used by hardware sites such as AnandTech’s SSD benchmark charts (which also includes ATTO) to show their results. The program uses incompressible data so some SSD’s will show much lower scores than usual if they compress their data.
Sequential and 4KB read and write scores will be shown along with access times and a final general overall score. The results can be changed to IOPS if you prefer from the View menu. A couple of useful additional benchmarks are available in the Tools menu like a Copy benchmark which simulates copying an ISO, game and a program, and also a read/write compression benchmark. AS SSD is also completely portable.

4. Anvil’s Storage Utilities
For an SSD or hard drive benchmark and test utility that really puts drives through their paces, they don’t come much more comprehensive than Anvil’s Storage Utilities. While being able to perform a complete read and write test using sequential and random operations, it displays a full set of results including response time, speed in MB/s and also IOPS (Input/Output Operations Per Second).
A total combined read/write score is shown in the yellow box. Also included are 3 extra IOPS tests, an endurance testing function and the ability in the settings to alter the amount of compression to use on the test file. More functions like a system information tab and a screenshot saver round off an impressive tool. Anvil’s Storage Utilities doesn’t seem to be developed anymore and the last version is from 2014. https://intensiveyou.weebly.com/tune-up-utilities-free-download.html.

5. HD Tune
HD Tune is probably the most well known hard disc drive benchmarking and diagnostic utility and will likely be in every tech users USB toolkit. The free version 2.55 is getting old now having not been updated since 2008 and might have minor issues with some of the latest hard drive models. Some functions like error checking and benchmarking should still work fine.
After a test, the benchmark result graph will show the minimum, maximum and average read speed along with the average access time in milliseconds and the burst rate. The block size can be changed in the options from 512 bytes up to 8MB and a slider can move between faster less accurate or slower more accurate test speeds.

Hello, i am looking for a Hard Disk/Drive utility that can scan and “repair” weak sectors.
Also interested to know if there is a tool that scan a hard drive surface from back to front and also randomly perhaps?

Naval architecture course. Bad sectors are usually a sign that your drive is starting to fail. If you have a high number of bad or pending sectors it is highly recommended that you replace the drive rather than attempt to repair it.
WD Data Lifeguard is a free disk diagnostic tool from Western Digital. It can run a “basic test” (checking SMART info), an “extended test” (full scan that locates bad sectors), or completely wipe the drive.
If bad sectors are found during an extended test, you will be given an option to attempt to repair these sectors. However, like I said above, it is recommended that you replace a failing drive.
You can also use CrystalDiskInfo (from the makers of CrystalDiskMark) to display SMART information and monitor drive health in real time. CDI once saved me from having to pay for expensive data recovery by showing an alarm for pending sectors before my drive died 2 days later.

CrystalDiskMark installs a hidden program on your computer that forces your browser to use a particular search engine.
ReplyThat’s because you are downloading the version with ads, get the one without ads to not have it install opencandy adware.
ReplySo how do you know which version your are downloading? With or without ads?
ReplyIn fact, there is no version with ads any more, the author removed opencandy earlier in 2016.
ReplyThanks for the heads up,
I was looking to download and use CrystalDiskMark, but not now!!

SSD drives aren’t effected by fragmented disk, so no shouldn’t effect the results
You should never run de-frag programs on a SSD, ever.

Yes and no. Defrag on a HDD, from Win 7+, it run Optimize, which is the trim command. This is very important. Why? simple.
An HDD is seperate into block and then into pages. It can only do 3 operations on block: Read, Write and Erase. It cannot overwrite like a hard disk. But it function the same way: When you delete something, it marks the pages related to these data as available, but not empty. A problem though, on page, it can only do Read and Write, not erase. Product key finder crack.
https://sigmatree412.weebly.com/firewatch-mac-os-x-download.html. When you have to erase a page because you run out of empty page, the ssd controller must copy all the good page in cache from the block (Read action + write action in the SSD cache), erase the block so all pages are empty and write back the good page from the cache. This operation take time and this is way your SSD speed degrate with usage.
Thus, in the early days of SSD, Trim appeared to fix this problem. When Trim is run, it does the operation above on all needed block and pages, thus leaving the SSD only with good and empty pages. This process does add some wear on the drive, but very little.
With time, OS and controller have implemented various way to bypass this problem, like doing the trim action on each erase, never leaving bad pages.

ReplyI did not see Hard Disk Sentential among your programs. I’ve been using it for years now.
3 years back it told me the bad sectors of the 750GB hard disk in my Dell 545 Inspiron had increased and its performance had dropped to 80%.
The system was still under warranty so I contacted Dell. After a lengthy phone call discussing the problem, they a sent a technician out. After 90 minutes, he agreed the drive was problematic, and gave me a 1TB replacement drive.
I installed the new drive, made it the boot and moved everything important over to it.
I made the 750GB drive a secondary just to see how long it might last. About one week later it failed.
I am sure those programs you list are great but I am thankful Hard Disk Sentential was recommended to me and have it on all of our computers.

Hard Disk Sentinel is a completely different type of software and is not a tool specifically for bench marking your drives.
Besides, it isn’t even free and this article is specifically about free software for the job.
ReplyInstalled HD Tach on Win 8. It will not run and displays a message that it will only run 2000 or XP.
ReplyGo to the Simpli Software program files folder and run the hdtach.exe in Windows XP compatibility mode, works fine then.
