SD card readers sometimes won’t compatible with SDHC and SDXC cards, so SanDisk released a program to format these types of cards to their initial state and make sure the operating system shows full capacity of these cards instead of seeing 64GB card only displayed 32G when the reader device has a maximum support limitation. Besides, this tool always capable of overwriting cards
Download this tool from the official site
Steps of formatting SD card are easy to follow in this utility, the screeshot shows how to perform, just plug in the reader, select the card in the main window, leave the formatting option as Quick format, click the Format button, and confirm this operation when prompted, then you’ll have no problem to read from and write to this device
Disk Management is the built-in disk manager in Windows, it’s now easy to access in Windows 10, the entrance is in the right-click menu of the Start button, so go ahead and click the option to open Disk Management, in the disk map, the connected drives (both internal and external) will be listed there, if the SD card is showing the right capacity, right-click on it and choose the Format… option, then Windows will pop-up the warning message says:
Formatting this volume will erase all data on it. Backup up any data you want to keep before formatting. Do you want to continue?, click Yes to continue if you had a backup of important stuff, otherwise you can Cancel out this operation.
Then in the format window, you can specify the following items:
The default setting is OK to go with, but as for external storage device, the exFat File system is better, you can use this instead of NTFS (also acceptable)
Diskpart is the command prompt tool to manage disk partitions, we can run diskpart from the CMD tool or directly run it from the dialog box (to invoke this tool press Win+R and type
diskpart and press enter), if this is the first you run this tool, you can type
diskpart list to see all the available commands there to manage disk and partitions, basically all the operations you found in Disk Management can be found in the list of commands too, so here are the screenshot and commands for formatting a partition:
Alternatively, you can directly type the
list volume command to list all the volumes and select one to format
The format option not only exists in Disk Management or the diskpart command prompt but also in the File Explorer Volume right-click menu. Press Win+E to open it or just double-click This PC on the desktop, to visually check how much free space left on the drive, or how much space had used, we can click the Properties option and check the diagram, when the diagram is not showing the full capacity of the SD card, we can use the format option, click on it and you’ll see the screenshot below
Options in this window:
Click Start to format, again, exFAT is the best option for external hard drives or USB devices
Not sure if you’re using some partition software or not, but the Format function is the basic feature in any third-party partition managers, take the Partition Expert program as an example, you can easily perform the format operation within the following steps:
or check the video guide below:
Format is aiming for getting a new partition ready, setting the file system, partition table and meanwhile empty previous data, its main purpose is to use the partition, data recovery software is able to pick data up and restore it. Wipe, on the other hand, is focusing on removing data, permanently, main purpose is to get rid of data so that no data recovery programs can get back anything
Both FORMAT and WIPE will delete previous data, the difference is that DELETE only removes the header instead of the content of data, more importantly, it sets the essential info to the new partition, WIPE, however, is the overwrite process on each sector, making sectors clean and nothing meaningful in them.
Windows has no wiping programs, but if you’d like to remove something from the disk for good, Data Wiper is recommended, another program from Macrorit, specially designed for data managing, removing, to be more precise.
