This newly updated post (first published two years ago)  has nothing to do with retirement or Asia. However, a mobile or cell phone, smartphone, tablet, notebook, netbook, computer, digital camera, pda or mp3 player has become a tool used by people of all ages, all around the world. Most portable devices have extra storage or ‘flash’ memory – a small removable card (micro SD) either inside the device or accessible through a slot or small flap on the casing.

There are quite a few types on the market from manufacturers such as Kingston and SanDisk, and they come in different capacities; several gigabytes are common on today’s new phones and tablets. For many, this extra memory functions as part of the system, without needing setting; they may not even be aware of the card or its features. But problems can arise when the card is nearly full and files need deleting, transferring to other storage, or replacing the current SD card with a higher capacity one.

Having had issues myself, I created a Micro SD page on the R-A website several years ago. Since then it has been consistently one of the most popular, receiving hundreds of hits every day – over 85,000 by 2010 and over 180,000 by 2012. There’s no doubt that many have problems and card failures; there are numerous forums where people post, including phone and card manufacturer support sites.

Two common problems:  microSD file transfer & Nokia phones with password-locked cards

1.  If a microSD cannot be recognised by a computer (read, write, format etc), it may not be the card itself but a microSD to SD adapter typically needed for it to fit in a standard size card reader slot. The adapter usually comes with it. This is the first thing to check for a fault. Try using a different adapter (Kingston seem to have dud ones); better still, get  a USB reader with a Micro SD slot for $3.50; in the UK for £1.40.

2.  Nokia phones with locked microSD cards that need a password for access (happens suddenly without user intervention). Retrieving or removing the password depends upon the model. Some Nokias have an “MMC store” folder; copy this to a computer and open with Notepad to find the password. Reformatting the card (losing all content) allows a new password e.g. 1234 to be set if needed.

Ways to copy/move files between SD cards or transfer to and from a computer

There are different options for working with files. One is with the USB cable supplied with the phone and used in conjunction with a software program also supplied by the manufacturer. e.g. Nokia Data Suite. Another is Bluetooth – a wireless link between the two, as also is WiFi. If you have a built in or USB card reader, removing the microSD card from the phone and connecting directly to a computer is easiest.

Some card readers now accept a micro SD card directly (see above); previously it needed a micro to standard size SD adapter often but not always supplied with a micro SD purchased separately and often the cause of problems, one of which is the write protect switch (on the adapter – the micro SD does not have this).

Whichever way you connect the card to a computer,  a file manager such as Windows Explorer should see an extra external hard drive . The drive letter (G in the image) depends on how many drives are already in the computer, including the CD or DVD drive.

The card’s folders and files (not always all of them) will be visible too and can be copied or moved by dragging and dropping them to a folder on another hard drive or perhaps burning a CD for archiving purposes.

Sometimes they are hidden or copyright-protected by the manufacturer and other means are needed to move or copy them. See our main MicroSD page for how to copy all SD card content to another location.

Due to the sheer scope of this topic, and the different problems that users experience, the web page  is long and rambling – even more so than this post – especially for someone looking for a ‘quick fix’. When I find the time, I will sort the information into categories and incorporate a summary on this blog, where issues will be easier to identify. Readers can also comment below and see answers which hopefully help others with similar problems.

NOTE: Before posting a problem with your SD card, PLEASE visit the MicroSD page at Retire-Asia.com. There are a lot of things you can try and tools you can download and use; most are free.

If you cannot find a solution there, (or you have found one and want to help others) you are welcome to post a comment. BUT you must provide the make and model of the phone, camera or other device, the card type (SD microSD, SDHC, SDXC etc), brand name and capacity (Gb) of the card. Describe the nature of the failure and the procedures you have already tried to fix it with the tools offered here or elsewhere.

Don’t comment “My card doesn’t work, I’ve tried everything; what can I do?” and expect an answer, but if you don’t see your problem listed here, below in comments, or on the R-A MicroSD page, then I am probably going to suggest you replace the card under warranty if possible, go to a phone service centre or ‘byte the bullet’ and just get a new SD card! They are pretty cheap now.
