The test length can be set to scan the drive just once, several specified passes, or leave it running until an error is found, or you tell it to stop. Other than checking for drive errors, it can also determine the read and write speed. To access the actions of “Read stability test”, “Save image”, “Load image” and “Full erase” you have to change the Access type from temporary file to a logical or physical drive. There are 3 access types and 6 action types for you to select. If the device is able to survive after a few cycles, the USB flash drive should be OK.

I have used this tool several times to run a burn in read and write test on USB drives. So here are 5 tools you can use to test the current condition and performance of a USB flash drive.Ĭheck Flash (ChkFlsh) is a very simple flash drive testing and maintaining tool. Windows comes with scandisk or chkdsk which I can use to scan for bad sectors but it lacks any soft of burn-in test or a test to check the true capacity. With all this in mind, I told him that I’d like to test the USB flash drives first before buying and he agreed. I have also heard several stories of people buying USB flash drives from places like eBay and their true capacity being only a fraction of what was advertised. The only thing I am afraid of is using a stick for a few times and it couldn’t read the files or can’t detect the drive anymore. So I thought that the possibilities are they could be either stolen or are rejected stock from the factory. He also told me that there won’t be any warranty if the USB flash drive fails. He couldn’t reveal how or where he got it from and that alone got me a little worried about the quality of the USB flash drives. It’s a very good deal when you can buy a $20 new USB flash drive for only $8. He had about 200 pieces, they are all new and are about 60% below the current market price. One of my friends came up to me a little while back and asked me if I was interested in buying some USB flash drives from him.
