Flash Memory Checkup Application
SD Scan Utility

Supported Memory Cards:Sony SF-G Series

Flash memory used in memory cards has a limited number of write cycles because it gradually wears out as data is overwritten repeatedly over time. Once a memory card has reached the limit of write cycles, it is no longer able to accept data for recording, even while shooting.

SD Scan Utility helps you check the condition of your SD memory card. By scanning the flash memory, it tells you whether your SD memory card is working in good condition or is about to reach the limit. Knowing the condition in advance, you can avoid missing your important moment or scene to be recorded.

Just install SD Scan Utility on your computer. It will automatically check your SD memory card when it is inserted to the computer, showing an easy-to-understand warning message if the memory card is coming close to the limit of write cycles.


01 Automatic Scanning When a Supported SD Memory Card is Inserted to Your Computer*

Inserting a supported SD memory card to the computer where this application is installed activates card scanning and instantly displays a result in the taskbar. (You can also manually start scanning.)

If the scanning result is "normal," it is just displayed through the icon in the taskbar without blocking your operations on the computer.

* Computer where this application is installed. You can use a card reader as well.
* After installation you need to select the drive into which you inserted a SD memory card. (for Windows PC)

02 Easy-to-Understand Scanning Result

The scanning result is indicated in an easy-to-understand manner through the icon and simple messages.
By clicking the icon in the taskbar (or on the menu bar in the case of the Mac), you can display a message window to learn more details.

03 Alert Message to Call Your Attention

If your memory card is close to the limit of write cycles, you will be alerted by a message recommending the use of a new memory card (this notification feature can be disabled according to your needs).

If the message “Your memory card is wearing out” appears, it is recommended that you use a new memory card, as soon as possible, in order to avoid a problem where the card suddenly fails to record data in the middle of shooting.

If “No more data can be written to your memory card” appears, you cannot record any more data to it. Use a new card immediately.
