![]() ![]() Someone not demonstrating "anti-disaster" protocol :-( "disaster advice" from someone who buys used cards. "Files are actual not deleted on the format,īut those cards were, most likely, NOT put thru Sony's Once you install it just run a deep scan. Recover deleted files or files from formatted sdd is Recuva. So the software I would recommend to use to It is kind of fun to see what people will Anyhow I have recovered many files of the sd cards I Matter are only overwritten when something else is write on top I was aware of most of that, so the lecture wasn't absolutely necessary, but I do see your point about improved write speeds and that does make sense.įiles are actual not deleted on the format, only the drive table is.įiles on the sdcards and hard drives(not true for SSDs) for that That last point is the important one, IMO, and its only sensible explanation for why Sony is erasing the SD cards during format - to improve write speed, particularly for video. This means, for write speeds from camera to the card, it is actually faster to erase the entire block during format so that the above situation is avoided and you can get maximum write speed when using the camera (important for Video) - just write the block (no read, modify, erase cycle needed).This means if you want to write a 0 to a place already holding a 1, then you have to actually read the block to memory, change the 1 to a 0 in memory, erase the block on the SD card, and then write the modified block back to the SD card. A storage mechanism which only allows binary 0's to be changed to binary 1.The controller is smart enough not to erase sectors which have not been written to, so actually its often relatively fast since it should skip already erased segments/blocks, but still slower than a simple format.So it is actually easy and fast - the overhead of sending commands is low, and the SD controller takes care of doing the actual erase internally. a command set which includes the Erase command, for segments, blocks and the whole device.They see block 0 to block X, sector 0 to sector Y. a controller which takes care to manage wear, the file system does not do that. Normal file systems do not manage wear.quite a long life, if your card had 10.000 write cycles (most have more), and you formatted it each day, it would last 25+ years.The program earns a score 4.5 rating points for its excellent performance in recovering and restoring the lost files and its overall ease of use.
