I put the micro hc 4gig sd in the adapter, but my usb card reader does not recognise it, and also my toshiba laptop sd slot reader does not read it either, all my other normal sd cards work fine, and they are up to 2 gig sd cards, I purchased this 4gig micro,hc card for my mobile Phone, any help would be much appreciated
Does the micro sd card been detected by your computer? If not, you may try other card reader, or other computer. If still does not detected, you may try to go to device manager and see whether the sd card is there, if yes, then you can assign a drive letter to the sd card.
Once SD card shows as a drive letter on PC, you can download sd card recovery software to get back your files. recommended asoftech photo recovery that helped me before. download it from link below
SD Card Recovery Software
You can refer to this card recovery tutorial
Recover files from SD Card
If above does not work, you may have to format the memory card (use quick format), and then use Asoftech Data Recovery to scan again the memory card and recover your files.
The problem is that a 4 GB micro sd card is HC (High Capacity). You will need to buy a card reader that can read HC micro sd cards (cost +/- € 8).
Very important: check if your mobile phone works with high capacity micro sd cards because a lot of phones don't work with HC micro SD cards.
Don't forget to rate, thks
SD cards are not created equally! There is so much more to know than just the
capacity.
There are many things about SD cards most people are not
aware of. After having numerous problems
with my cards, I thought I would share what I learned, mostly from online
articles, trial and error!
There are SD cards (Secure Digital)
SDHC cards (SD high capacity)
and SDXC cards (SD extra high capacity, high performance)
Speed Class: There
may be a C with a number inside the C printed on the card, (or a U with a 1 in
it) - if there is no C or U on your card, it is a C2 card.
C2 is for basic data and photo use and has a slower
processing speed.
C4 and C6 are acceptable for up to basic video.
C8 and C10 are high performance, fast processing speeds -
and cost more.
The U1 symbol indicates fastest processing speed available,
and will cost the most. For large size,
HD videos.
If you are trying to use a basic SD2 card (no C rating or C2
rated) for a high quality or high speed video or large RAW photo, you may have
problems with your device. The card may
not be able to keep up speed-wise. These
are generally older, or lowest priced cards.
More information and photo examples on the speed class here: https://www.sdcard.org/consumers/speed/speed_class/
Your device will read SD cards up to the capacity it is
capable of. A device with SDHC capability
will be able to read basic SD cards, but might not be able to read an SDXC
card, so you may think you have a defective card when you actually just have a
device that does not have the capability to read it.
If your computer's SD reader or
peripheral card reading device has an SD card reader and it cannot read SDHC
(high capacity) or SDXC (extra high performance/capacity) it will reject or not
see the card and you might think you have a defective card. Put the card in your camera or other device
you are going to use it for, and then using the USB cord that came with the
device, plug that into your PC. The PC
will be able to read the card that way, edit it, etc.
After copying all files on the SD
card to your computer, you may wish to format the card before using it
again. When formatting the card,
IMPORTANT: Make sure you have copied all
the data you want to keep onto your hard drive, and make sure it is formatted
FAT32. I kept formatting a card FAT (which
was the default for this card), and the recordable capacity of the card kept
getting smaller...and smaller...a 2GB card was only allowing 350, 250, 125 MB of
data to be stored on it! I kept hitting
a brick wall trying to copy files onto it.
I kept formatting the card, thinking there was some de-frag issue or
corrupted portion, and the capacity of what it would store kept diminishing -
until I formatted the card FAT32. ONLY
THEN was the card able to store to its true capacity. I was able to do this in Windows in Explorer
- right click the drive the SD card is in, select Format, verify the Capacity
(card size), verify the File System (use the pulldown menu to select FAT32 if
it is not selected), and then click Start and allow the computer to remain
undisturbed until the format is complete.
I found a web page that covers this:
http://pvillecomp.com/
There is an SD website that offers a
download for proper formatting of your SD card, with downloadable
instructions. I was using Windows to
format my SD cards, but the SD website recommends using software that
specifically formats SD cards. Here is
the site: www.SDcard.org. Click the Downloads section.
Some older devices can only handle
smaller SD cards (2 GB or smaller), so if your device cannot read a particular SD
card...check your owner's manual. There is
usually a limit to the size, capacity, speed, type, etc. of the cards each
device can handle.
It is also possible to partition an
SD card so it can be read by more devices, or separated for organization
purposes. I prefer smaller SD cards when
possible to avoid a huge loss if the card becomes damaged, lost, etc., but for
those who have cards that are 16+ GB in size they may want to partition
them. Here is a website for that:

Hope this helps!
Mine was working then i the phone says you need 2 gb of free space So when I try to delete stuff It didn't work and when I tried to format it it said not allowed but when I took it to best buy they Said it deleted everything and the reader was bad so I bought a new card reader and it won't let me save anything Same goes with the new micro sd card
SOURCE: Micro SD 2 GB just stopped working
I had this same issue added music to my card did a safe remove from my comp. placed in phone and it stated "No memory card inserted" and wont read in adapter in computer Im so Sad i lost all my pics/memories :( it just means that the Card is Fried (Burnt Out) no way to fix this their just like SIM cards In 3G phones and if the copper bars get scratched or bent just the slightest bit it kills the SD card.
SOURCE: pc not recognizing sandisk micro sd
The Card Reader you are using is probably not compatible with SDHC Memory Cards (High Capacity SD). You may need to get an SCHC compatible reader or check the website for your product to see if the is a driver update. You can get a new reader for about $20 bones if needed. I had the same issue.
SOURCE: Hello,
Hi , the most likely cause is your card has been flexed and this causes internal damage to it , sorry but no repair is possible , i have a sizeable collection of cards that have been damaged the same way .
