data recovery - Recover SDHC card used in an SD card reader


A while ago when SDHC cards were fairly new and all the office computers had only SD card readers, I made a 4 GB Class 6 ADATA SDHC unreadable and unformattable by trying to get it to work in SD card readers.


Have methods emerged since that time to make such SDHC cards usable again? Perhaps using low-level interactions with the logic on the cards?


Answer



You may be able to use the SD Formatter 3.0 from the SD Association to resurrect your card using a compatible card reader.


If that still doesn't work, it appears from the page linked above that you may have corrupted the "protected area" secure part of the card's filesystem. It is possible that running the card through a "format" or "initialize" function present on another SDHC compatible device (like a camera or media device of some sort) might do the trick.
