Not only are these counterfeit but they often contain less storage than the cards report to the computer. After filling up all of the real space, the card will respond as if it is storing the data but it is actually throwing it away.
The files will look like they exist but they are actually full of null bytes or completely corrupted. Scam SD cards are common. Remember, if the price is too good, the product is probably bunk. Do we have any alternative? My fastest non-phone net speed is 5Mb in and out.
App is brilliant! If these dodgy cards are made by getting a card to pretend to be bigger than it is, then is it possible to get it to stop pretending, and use it at the correct size? It depends. I ran h2testw on the card yes found Linux version , and after 16GB of data was written, you could no longer write to the card. Re-formatting, re-partitioning, deleting existing files: all failed.
The card was totally borked. I complained to the seller, and he refunded my money. I told the seller his inventory of cards was all junk.
He said he never heard of this scam before. This was a couple of years ago. Was it a fake or OK? The crazy thing with this scam is the fakes are sold by reputable retailers. It may not be the manufacturers fault, but why not provide a utility to verify if a product is legitimate? They could provide a utility that users could download from the manufactures website for testing suspect cards. Samsung could make a utility to identify legitimate Samsung cards, Kingston could make a utility to identify Kingston cards, etc.
Any one of them could make a utility to write to a card and do a capacity test. They make the cards, they should be the best at writing software to check them. They must have their own reasons, maybe this problem is not so widespread to warrant any attention. They probably know what they are doing, if you purchase your SD Card or Thumb drive from a reputable retailer, you have nothing to worry, and if it is fake, the manufacturer will take action and you can sue the retailer for money due to data loss.
There are plenty of fake and counterfeit products around and the world of computers is not exempt. In recent years one area has become more prone to this than any other, and that is flash memory storage.
You may think this problem only affects places like eBay but even Amazon and other legitimate retailers have been caught out too. Making sure the serial or code number on the stick is legitimate is one way, another is making sure the drive is the size advertised because most fake drives have a lower real capacity than listed by using smaller and much cheaper memory chips.
The drive may even be reported as the right size in windows. Software developers are also aware of this and some have written tools to help you identify if a drive is smaller than you expect and is therefore likely to be counterfeit. Here we have listed 5 for you to try that are designed to check for fake size drives. For several years H2testw has been known as the go-to tool for checking memory based flash drives to see if they are the correct capacity.
The problem is it was developed back in when flash based media was smaller in size. A scan with H2testw can run into several hours or even days on newer large capacity drives, especially if they also have slow write speeds.
However, it could be a price worth paying. The method used in H2testw is very slow but is still one of the most thorough and reliable ways to scan the drive for a fake capacity. H2testw works by writing large 1GB files to the free space and then reading them back. You can also select a custom amount of data to write which is useful if you suspect your drive might be a specific capacity. If you have the time and want a very thorough test, try H2testw. It defaults to German language but you can easily change it in the GUI.
Download H2testw. One component of RMPrepUSB is a quick test to check your drive and its real capacity, this is an extended and enhanced version of that and is released as a standalone executable. Unlike some other similar tools, FakeFlashTest is not that old so includes optimizations and methods better suited for modern flash media. FakeFlashTest tries to fix the main issue with H2testw which is the long time it takes for the process to complete on larger or slower flash drives.
This writes and reads bytes of data at set intervals across the drive and so finishes in less time. It starts at the end of the drive first so should pick up an undersized flash drive pretty quickly. The second test is similar to H2testw and writes to the free space on the drive then reads it back to verify.
The process has been optimized to hopefully complete the task much quicker than H2testw. Do note that the the quick test is destructive meaning anything on the drive will be overwritten, so make sure your files are backed up.
Download FakeFlashTest. It works in a similar way to H2testw by writing data to the device, reading it back and then comparing the two for differences. Any errors indicate a problem with the drive. This tool is made in Java so it can run on other operating systems like Mac and Linux as well as Windows.
It does obviously mean you need Java installed on your system. To run Quick Disk Test, you may have to right click on the.
Click the location button at the top to select a drive. How much data you want to write is up to you. Alternatively, use the leave free option to do the opposite. Data already on the drive is not overwritten but new data is added to fill to the selected amount. A useful function is being able to stop the process while writing data to the drive, restart the program later and continue filling where it left off. Download Quick Disk Test.
The programs listed above all work in the same way which is to physically write data onto the disk and then read it back to see if the data is correct or corrupt. Run the program and look for the information about the flash chip inside your device, a line will give the vendor and model number of the chip and hopefully its true capacity. Right click in the window to copy all the shown data to the clipboard.
Note: Be aware that ChipGenius generates a number of false positives with online virus scanners like VirusTotal. Final Note: Apart from ChipGenius, all other tools write data to the drive.
Whether the tests are meant to be destructive or not, it is highly recommended to backup anything still on the drive. Data has been known to get destroyed when drives have real errors on them or capacity issues. I have tried to download Chip Genius in both the Russian and Direct Download, and the same page is just reopened. Example of usage:. Your data should not be corrupt.
