Taken care of with cards SD `asesinas'

Lately there have been enough problems with cards SD, that damage the reading unit of electronicses, like for example the Palm. In PalmAddicts they have found a page of the own Palm, in which one occurs to know one the causes, of that they cannot become responsible: the noncompatible card sale with standard SD (normally to lower costs).

According to Palm, market has detected in series of cards that does not cuemplen with the standard dictated by the SD card association, whose continued use can take to the permanent damage of slot of expansion of several devices, including the Palm. Palm argues that their apparatuses are designed to work with cards that follow the standard, reason why recommend not to use these other cards. Next they give some directives to detect these incompatible cards us, obtained after proving they themselves a great number of models:

  • Lack of the cracks: the card can not have the small cracks, typical of the cards that follow the standard, in the lateral ones.
  • Lack of the switch of writing permission: other noncompatible cards did not have the small switch of two positions, who allows or not operation it of writing, even though the documentation that accompanied the card said that it includes yes it.

  • Badly labelling: other discrepancies with the documentation also can identify noncompatible cards. For example a card of 256Mb that brings in the written label 128Mb. In case of thus detecting something, we will have to put to us in contact with the manufacturer of the card, to clarify the fact, or to remedy it.
  • Logo SD: noncompatible cards can take to form in the label the compatibility logo. So we do not have to trust by this fact.

The symptoms to use one of these cards can be the following: the first time we inserted that it, recognizes it to the Palm and we can use it, perhaps we removed but it, does not return it to recognize more never. The case that can occur slot does not return to detect no other card. In that case, it will have been damaged permanently.

If that were our case, we will be able reparala being sent it to a technician, but the being a damage caused by a product of third parties, will not enter within the guarantee of the apparatus. Additionally, we can put to us in contact with the manufacturer of the card on the contrary to obtain one that is compatible with the standard, or, to ask that our money is given back to us.

And this is everything what Palm says to us. So we must have well-taken care of and so we bought, and to watch the explained points. Of all ways, we either do not have to be too alarmist. I use a card SD of 512Mb of the recognized Kingston mark, with guarantee of by life, and have noticed that when coat the card and I return it to put, sometimes the Palm does not recognize it to me, but I repeat the then operation yes. I do not believe that my card does not fulfill the standard, although everything can be. It is more, are many other causes for a bad operation of slot SD. In order to learn more, we have the solution of problems with cards SD and MMC.
