Mobile phone TF / SD card (mobile telephone memory card is smaller than the modest fingernail microSD card) Pc can recognize the card, can recognize its capacity and may read the files inside the card, but can not write files, nor format! Attempted the following solutions to no avail:
(1) Use the Windows formatting prompt 'Windows can not full formatting'.
(two) Enter 'CHKDSKH: / F' below the MS-DOS command, the completion degree is 0%, and stop.
(three) USBboot, formatted with HDD, can proceed smoothly with out error, but following the completion, the files inside the card are still there, as well as the difficulty remains.
(four) SDFormatter, prompting the card 'The storage medium you selected is in a write-inhibited state'. It must be explained that there's no create protection switch on the TF card, nor around the card reader.
(5) Use a digital camera for formatting and low-level formatting, and automatically exit when it reaches 50 or 60 %. The files in the card are nevertheless there, and the trouble remains.
(six) Delete the files inside the card beneath windows, it appears that it can be deleted typically, there isn't any error message, however the card is pulled out and reinserted, the files in the card are nevertheless there, along with the dilemma remains. When employing a file shredder for example 360, and choosing deletion options for example prevention of regeneration, put it overnight and nevertheless prompt 'in progress.'
To add: use various unique card readers to install the card, and use other TF cards for comparison, and use other computer systems to test, and distinctive operating systems. And use a number of different mobile phones to attempt. The result is that the issue remains.
I've attempted different methods previously handful of days. I'm afraid that the tf card has turn out to be read-only. I am not the only one encountered. The several strategies on the internet are invalid. You'll find data inside the card, photographs, and so on. It's not simple to ask for warranty. Just remove the card reader:
Very low cost card reader. I purchased five of them inside the mobile phone shop at that time. The speed can also be incredibly slow. It is low-cost and low-cost. I stumbled upon a needle in the deck that may be a sauce purple drop:
Why do you pinch? So I searched the datasheet on the tf card and identified such a component of content material:
It turns out that the sd card and tf card also possess a spi mode. This spi mode makes use of two fewer pins, which can be handy for communication with all the microcontroller. Is the design and style of this pin on the card holder various? I guess if an external slider is added, plus the slider is pressed to depress the needle, in order that it can not get in touch with the tf card, can the card reader enter the spi mode? To understand that you'll find not many people who have attempted to access the tf card in spi mode on the personal computer, and the result is unknown. I ought to be a crab eater, haha, just do it:
See, as long as you cut a piece of transparent tape and stick the initial foot with the tf card, you could force in to the spi mode! Just before
http://www.google.com , the content material of your file around the card was displayed on the laptop as a result of the partition, the capacity is less than the original, (click the name to download) usboot can not operate typically. Now plug it in, the personal computer straight prompts that it's not formatted, let I format the card, I go, and use usboot application:
What is the result, guess? The result is not surprisingly repaired.
If you possess a terrible card in your hand, give it a try.
image data recovery software do n’t assure that all card readers support the spi mode. Only my two card readers can do that. The card reader on my laptop wo n’t operate either. Repair the undesirable card youngsters ’s footwear. Leave a comment in the comments under.
