SD Card problems « on: March 16, 2017, 06:17:24 PM » Author: wattMaster
One of my cameras are acting weird, whenever it tries to write to a particular SD Card, the files are corrupted and causes the camera to crash. The other files are still readable, luckily. Is the SD card already worn out from repetitive writes?

Where are daylight fluorescents when you need them?

Sounds like the SD card is probably shot, they're cheap so just get a new one. :lol:

I've went through a few XD cards myself.
Always starts with write errors/corrupted files.

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

One of the great disadventages of flash memory (One of the reason why I stay away from SSDs) is that they are limited amount of writing times. When all the area of the card is consumed, writing problem may arises.

SSD's are made by far more reliable than "disposable" flash devices

With that said, i only install SSDs at work (IT) or to family (to make the refurbished PCs i made for them work fast). As for me, i use old HD's (which i get for free from trashed PCs). Also, SSDs are far more expensive than HDs for storage space unit

I've heard that SSD crashes caused by power interruptions is very common, in contrast to mechanical HDD.

Yep they don't like being interrupted during a write cycle and a mechanical disk has enough momentum while spinning down to even park the heads they are actually designed to do this so they survive surprisingly well. But you can get power loss protected SSD's they basically use DRAM memory and a capacitor to support the DRAM to the large NAND memory writes should there be a power loss, however there is a cost to this so they are not normally found in consumer products, and UPS's are getting cheaper and offer more protection and allow for an orderly shut down and can even keep the desk light running so you have time to find the flashlight, so unless you have critical data, the UPS makes more sense for consumer products, and if you have critical data the UPS would already be there to support the generator turn on delays, and you would have enough fuel to support the mag tape write times which will keep your data for fifty years or more..
