We get lots of questions from readers, but one that never gets quite the right answer is what to do about memory cards that are on the way out. So what do you do if an SD card is failing, and what happens if you accidentally break one?
The topic of memory recovery is one of those things we get asked about generally when it’s already unfortunately too late. It usually occurs when someone trie to take images off a card, and either finds nothing waiting for them, or accidentally chips the card when trying to take the card out of a device, likely a camera, a tablet, or a computer.
But memory recovery is one of those sticky subjects that rarely offers the right answer, because while you can often salvage a hard drive, memory is a little more complicated.
When memory cards fail, the information isn’t necessarily easy to find, and in many cases, can phase in and out of being readable, with the files there one minute and gone the next. This can make the recovery of information difficult, because when a card is failing, it is unreliable.
Technically, your files are still there, so that’s positive, but the degradation of the memory can make it hard to see, and the index that categorises all the files on your card may be corrupt, making it very difficult to get the information you need.
How it happens
Memory is a complicated thing, and while it might seem like a card is just a bit of plastic that holds images and movies, it is far more complicated than that, with millions of transistors sitting inside, a processor to tell the card where it should be storing things, and then how these bits are treated and made.
And there are several factors that make up a card, determining if the card you bought it good enough to last a week, a month, a year, or longer.
In fact, there are four basic questions tech people like this writer have for anyone that asks us to take a peek at their memory and tell them what is wrong. They are:
- What brand of memory card did you use?
- What size was it?
- How old is the card?
- Where did you buy the card?
Each of these questions can give you an indication into what has gone wrong, and while they won’t necessarily help you recover the files, they’re useful to know to help you in the future, and possibly a professional if you end up paying for one to look at your files.
For starters, the brand is important. Almost every brand has a different way of fabricating the memory needed to make the memory, and there’s more to a memory card than just a block of storage, because there’s a small processor thrown in, too.
As such, the big names, brands like SanDisk, Lexar, Kingston, Samsung, Sony, Toshiba, Corsair, PNY, and PQI are likely the names you want to take a look at first, because they’re already established players in the memory market and have a fair degree of experience making storage products in the first place.
Smaller names can pop up here and there, but unless reviewers (like GadgetGuy) have said good things, tread carefully, as these can often be cheap, but cheap for a reason, and when it comes to storing your precious memories, cheap and nasty is the last thing you’re going to want.
Next is the size, and this is vitally important because larger sizes generally denote delays for people making backups.
