How to recover the memory capacity of an SD card?

There are two main ways to recover memory card data:

1. Restore from a backup

That is, to restore the original data through a backup file in your computer's hard drive or cloud storage. It's very simple, completely autonomous, and it's quick and effective, with little to no failure. But it has a very harsh premise, that is, users need to back up the files in the USB flash drive to the computer hard drive or the cloud in advance.

Without this careful preparation, this method would not have been possible.

2. Use a professional memory card data recovery tool

For users who have not backed up in advance, formatting the data in the memory card is not unrecoverable. There is also a fantastic way that can help you get back your lost data, and that is by using a professional data recovery for memory card data recovery.

Let's take a look at the specific steps with the help of data recovery software.

Step 1: Connect the memory card you want to recover to your computer.

Step 2: RunLost data recovery software, select the "USB flash drive memory card" function to enter, and then select us to connect to the memory card.

Step 3: Select the file types you need to recover, and click Scan after selecting them.

Step 4: After the scan is completed, there is a lot of data, find the files that you think are more important and must be recovered, preview them, and preview them normally, it means that the files can be recovered, after confirming the files you want to recover, check them and click the recovery button below, so that all the data can be restored to the computer.

If you say eliminate volume, the capacity is a fixed amount at the time of delivery, like a bottle that can hold one liter of water, you can't change its size. If you say to eliminate the contents of the SD card, just format it, like you can't change the size of the bottle, but you can dump the contents of the bottle.

Use the 360U drive authenticator to test your memory card first, and if there is an expansion, its actual capacity will be reported. For example, if you take an 8G memory card that is expanded to 64G as an example, the USB flash drive authenticator will report: Nominal 63G, true capacity, expand, write down the real capacity!

The data is different from card to card, which doesn't matter).

02 Open, select the memory card, delete the original partition, and then create the partition, at this time, you need to pay attention, fill in the real capacity just now in the "Please specify the size of the new partition", in order to retain the maximum effective capacity, you need to convert: , you can fill in 7450M in the "Please specify the size of the new partition" (in order to ensure that it is effective, try to be slightly smaller than the real capacity checked out in the first step), and then select the FAT32 format in the file system, fill in the appropriate volume label, OK, select "Yes", and then execute. After completion, the disk becomes a USB flash drive equivalent to 8G specifications.

03 Use mydisktest to check the card, if the capacity selected in the previous step is less than or equal to the real capacity of the disk, mydisktest will confirm that the non-expansion disk is done, and it can be used normally. If the partition capacity selected in the previous step is larger than the real capacity, for example, 8000M, MyDiskTest will report that there is an expansion, and at the same time display the real capacity of the disk (it may be a little different from the 360 USB disk authenticator, it doesn't matter), at this time, you can repeat the PQ process above, delete the original partition, recreate the partition, and select a number slightly less than the real capacity. When you're done, check it with mydisktest.

This method has been proven to be effective after many practices, the equipment is stable, and the storage documents are complete and reliable.
