At present, flash memory cards of digital cameras are mainly divided into SD, ms, CF and XD. The probability of problems between SD card and CF card is much lower than that between MS (memory stick) and XD card. Now list the matters needing attention in daily use one by one to protect our memory card and data:
1, don't format the memory card on the computer. At present, most computer systems of ordinary home users are Windows XP, and the default format is FAT32, while digital cameras are in FAT format. Therefore, the flash memory card can not be formatted on the computer, or it can not be used normally on the camera after formatting. If you need to format the memory card, it is recommended to operate it in the camera, which is fast and safe, but one thing should be noted, to ensure that the camera has enough power during the formatting process.
2. Do not install or remove the memory card while it is open. This is also a common mistake that users make in their daily use. Installing or removing the memory card when the camera is turned on will not only lose data and damage the card chip, but also damage the digital camera. In addition, you can't just turn off the power and dial the card immediately. Some cameras have slow storage speed and are still stored after being turned off. At this time, you will find that there will be an indicator light on the camera body, which will light up or flash, and you can operate after the indicator light is completely extinguished.
3. Inferior card readers or extension cords may also damage your memory card or data. Sony digital camera users often encounter the problem that they can browse the camera normally after the photos are taken, but after being transferred to the computer, some photos can only be displayed in half or in confusion. Users who have never encountered such problems may be puzzled. If there is nothing wrong with them on the digital camera, they will not be transferred to the computer. In fact, the reason is very simple. Your camera is normal. The memory card is also normal. The problem lies in the card reader or USB extension cable. The solution is also simple. Either connect the computer and the camera directly with the original data cable, or remove the redundant extension cable from the card reader, or replace it with a better quality card reader. So is there any way to remedy the photo damage caused by the previous connection error? Unfortunately, the picture information has been damaged, and there is no way out. Some user information is more important to get to Guangzhou digital camera repair station for processing, and the result is of no help.
4. Pay attention to the front and back when inserting and pulling cards. It sounds as if no one will make mistakes, but there are often many mistakes. The author learned in Guangzhou Southern Digital Camera Maintenance Center that many failures are caused by memory card operation errors. In recent years, Nikon D70, D70S, Fuji S2 PRO, S3PRO, Canon 350D and many other photo studio machines can't use the card slot because the CF card is inserted backwards or not in place. The damaged card slots are very small, and some can directly burn out the main circuit board of the camera. In addition, some people like to put their mobile phone TF or MINI SD card in the camera. It's not impossible, but I often hear that the card sleeve can't be pulled out. It's better to buy another SD card for digital cameras.
5. Physical damage such as heavy pressure, squeezing and impact can directly damage your flash memory card, but keep away from corrosive substances such as liquid. In addition, if there is dirt on the contacts or contacts of the memory card, it can be gently wiped with a cotton swab, and it is forbidden to be brutally cleaned with hard objects.
We may seldom use these digital tricks, but taking a few minutes to get to know them may save us a lot of unnecessary trouble. I hope the above mentioned content can help you!
