How to detect and solve storage device expansion problems

How to identify and repair expansion card

Today’s expansion card technology is more advanced, and sometimes the expanded capacity is still displayed after formatting. Therefore, when storing data, we will store it according to the expansion capacity. However, when we read the data, we may encounter content that cannot be read, which is really inconvenient. In order to test the performance of the expansion card, you can download two software: mydisktest and USBOOT. You can find these software with a simple search. These software can help us evaluate the performance and stability of the expansion card.

Use USBOOT to format the memory card first, because sometimes it may not be detected directly with mydisktest, which makes people sigh. Nowadays, people who make shady money have become more sophisticated.

After opening, an interface like this will be displayed

First, select the disk you want to format. Then, click Select Working Mode below and select HDD mode in the drop-down menu. After selecting, the interface will display the corresponding settings. Next, click Start and follow the prompts. During the operation, you will be prompted to remove the memory card, just follow the prompts and remove it. After a few seconds, you will be prompted again to insert the memory card, and then reinsert the memory card (note: I inserted it into the computer through a card reader).

After this is completed, basically you can see the actual capacity by looking at the properties of your removable disk!

Run mydisktest, select the quick expansion test after opening it, and wait for the automatic test to complete. The test results showed a complete failure, which is very unfortunate.

Then start the repair, click Start

I would like to remind you that after clicking this, the next step is to ask you if you want to continue. I habitually clicked continue without even looking at it, but ended up going back. After a closer look, it turns out that step is Click to cancel before continuing...

I also forgot to take a screenshot. Please take a closer look. Anyway, they are all in Chinese and everyone will recognize them.

I won’t explain the following step by step, because they are all in Chinese, and everyone will know it at a glance (mainly because I forgot to take a screenshot, hehe)

Then it looks like this

Then you will be prompted to format

After the formatting is completed, the repair will be successful.
