Yes, few people seem to even know of its existence and even fewer seem to know about ut. Thems that do do not appear to be too forthcoming in the enlightenment dept. To me, it is because of all these mirrors and smoke that fraudsters get a foot up into our bank accounts and that if things like SD secure areas were more transparnt, the we would all be safer - and that includes the manufacturers too! I have no doubt though, that this is all so secretive for a reason. That stirs my curiosity!
The secure area is fundamental to the "Secure" in "Secure Digital" SD cards rarely actually use their secure function, despite their name, if they do however use it then the encryption keys are stored in this secure area, having this visible for all to see would allow you to easily wipe the keys and render everything on the card useless (having access to the area does not make it possible to decrypt the data without the original device it was used with). This area is also used to store information about the card which is common in fake cards, its also believed to be used to make the cards appear faster in certain tests to help them gain the "class" rating. There is really no need for anyone to have access to this area of the card and doing so can potentially lead to problems.
Absolutely everything you write just belittles you in every way and proves me write. I stand by what I say in that you do not fully read everything, consequently you go off half-c_o_c_k_e_d and look all the more foolish because of it. Read back from pages 4-5 of this thread where you will see that jokiin and I did not have the best of starts and that he has indeed been rebuked by me for what I thought was his unhelpful comments. That we are now so quickly getting on so well should be a lesson to you and testment to the fact of the benefits to be gained from an intelligent and mature approach to things. Do I value jokiin's input due to his undoubted superior knowledge of this subject. You bet I do. That is precisely why forums like this exist (not to win points for how many threads you add comments too however inane) and it is for precisely the same reason nothing whatever that you have to contribute can or will be of any use to anyone unless and until you grow up a bit and stay focused on the tasks at hand rather than acting like an immature, spoilt brat!
Your rambling, can you also try and explain your comments, immature?, spoilt brat? ill put your show of disrespect down to your age.
Well how in the hell would you know anyway. You weren't even born then!
I know because I am capable of learning and have spent all of my life learning, it is a tad arrogant to assume that ones knowledge of history begins at their birth. Presumably you are aware of the Second world war? that predates yourself but I wont assume your know nothing about it, you could well be professor of history.
so why assume that someone here who is younger than yourself who actively engages with people to help them and to better their own understanding of technical subjects is going to be ignorant of the history of technology? you assume my friend that some other people are below your level of understanding. I wont pretend to know everything, this is why I push the envelope of my understand and test issues such as these SD cards, I have built up a great deal of knowledge around SD cards and how they work, I do not know everything but do not dismiss this unless you have actual knowledge to the contrary at which time I will take my hat off to you and graciously learn something new.
My goodness. I had no idea that every SD card has its own Micro controller. The 1st 20 mins of this video were very interesting but from there on out (when talk of code 8051 got thick and fast) it all went over my head a bit. Nice too to know that SD cards do not actually store data but at best only store an approximation of it. Just makes me wonder if I should curb my impulse to go to SSD drives in my PCs until I learns bit more about their CONS as well as the obvious PROS!!!
Generally speaking SSDs are fine, get as big a drive as you can afford which will help offset the gradual decline of its integrity. If your looking for storage that's bomb proof then HDDs or SSDs are not what you want, both can easily be corrupted. For all intends and purposes, SSDs today are more than adequate to use safely without fear of them dying, in fact your more likely to get a mechanical HDD fail than an SSD after the first year of use.
I absolutely and categorically disagree with you on this point. No other device that I know of rejects cards like this F750 (see my post later on). Cards rejected by Thinkware are accepted by just about any other device I can lay my hands on. When have you ever heard the likes of Apple, Samsung, Lenovo, HP et al ever state SD card acceptance nay be problematical? Exactly, the never do. So all this nonsense points to Thinkware being the problem NOT the cards (given you have what Thinkware state if pressed - a UHS-1 class SD card up to 64 Gb formatted in exFAT with sector size of 125kb - but then it must but not work - Ye Gods what utter rubbish!!!).
Why do you disagree? I actually hope you have learnt by now that your presumption of thinkware being the problem is incorrect, if you have reached that point then I hope you also see how your comment has come across as being wrong, I further hope that you then take the next step and concede that other people know things that you do not which IS the reason we are all here.
Try answering why despite your claims of being impossible so that you and another insist I should take it on the chin, that Thinkware can do what you claim is the impossible by selling SD Cards that are guaranteed every time to work. Then perhaps we might think you have something worth contributing.
And no, I do not see that there is any diffence in a 1Gb or 1GB drive. To me they are exactly the same thing and anybody that says different will indeed be teaching me something. So come on then Dee82 teach me what you imagine to be the difference between 1Gb and 1GB.
"So come on then Dee82 teach me what you imagine to be the difference between 1Gb and 1GB"
THIS is the kinda thing you need to work on and why you come across as being rude, "what I imagine to be the difference"!?! Blimey man can you just try and have some respect for other people! I don't imagine anything to be the difference, I KNOW the difference otherwise I wouldn't have brought it up!!
Thinkware can guarantee what cards work by simply testing them and having them manufactured to very strict criteria, other manufactures may not have the same degree of criteria, even within the same company two same models of card may function differently if they were not designed to the correct spec of the camera.
GB and Gb. B=Byte b=bit. Usually one refers to storage matters in terms of Bytes and transportation of data in terms of bits.
There are 8 bits to every byte. So an 8Gb HDD is actually approx. 1GB (which indecently, didn't exist in the home market in the 80s and I'm not sure that it even existed as a single drive in the enterprise market)
So to directly answer your question, 1Gb is about 125MBs, 1GB is approx. 1000MBs ( its not quite that simple, 1GB is actually closer to 1024MBs but with the sizes of storage we now talk about its more or less redundant, back in the day however that error of 24MBs could be a big problem, it also doesn't take in to account that storage isn't 100% efficient, file system and cluster sizes effects the actual amount of data that can be stored)
There you go, I do hope you have learned something, respect being one of them.
