How to Repair a Corrupted Memory Card + Correct treatment of a memory Card

In this post, i shall share with you how you can
Repaire A Corruptted MMC And Correct Treatment of your MMC:
Physically, memory cards are quite fragile pieces of
high technology, susceptible to damage from various
silly things like excessive heat, condensation, strong
magnetic fields, physical damage from rough handling
and/or bending! (similar to most electronic devices
then..)
Given the natue of mobile memory card products,
they are constantly being taken in and out of some
form of interface with a mobile phone, a camera, a
laptop, or desktop PC, or a separate memory card
reader. The number of different devices they have to
be able to interact with is in the thousands.
It is not too surprisingly, then that sometimes the
state of the file system on the memory card can get
damaged.
This may happen for a number of different reasons,
including:
> removing the card from a device whilst an
application is trying to read/write to it.. (Just be
patient…)
> battery drain on a device whilst in use meaning an
insufficent voltage failure whilst writing to the card.
> a poor implementation of the MMC standard on the
device using the card
> poor connectivity software drivers on the device or
the Windows PC/Mac
> physical damage like card or device being dropped,
bent, getting wet etc…
> lots of others i am sure..
As often as not, the problem is not terminal for your
memory card, but just a software issue ( or in
physical terms, it could be called “a temporary
disalignment of the all the bits and bytes on the
card”).
The fix for this problem is the same as for any other
file storage device (like a floppy or hard drive) with
corrupt or invalid file system, namely; re-format the
file system.
Re-Formatting your MobyMemory MMC Card:
It is possible that your mobile will offer you the
option of formatting the memory card if it is found to
be invalid. (However, the likes of Nokia nGage, Nokia
6600, and Siemens Sx1 often just prefer to reject the
media as corrupted).
In that case, to format the card, you will need access
to one or more of the following:
> A Windows PC or Mac.
> A separate multi-format memory card reader
(verify that it is compatible with the MultiMediaCard -
MMC- standard).
> (This can come in USB or PCMCIA flavours. If USB,
try and ensutre it is a USB2 device.
> Alternatively, many of the newest laptop and
desktop PCs now come with integrated Multi-format
memory card readers.
> If you are using a separate memory card reader,
then connect it up to your PC, and let windows
recgnize the device through plug-and-play.
Now you can insert your MobyMemory card into the
appropriate slot in the memory card reader. (Please
note that because the MMC card is pretty much
symmetrical it is very easy 2 insert it upside-down in
d slot
Open up [Windows Explorer] (or the equivalent for
MAC users..sorry not well-versed in OS X).
There should be at least one icon visible for a
[Removable Drive] in the list of available drives. (in
fact, there is often a list of about 5 or 6 Removable
drives, one for each of the different Memory card
formats that your reader is compatible with).
Find the drive that is mapped to the MMC card by
clicking on each in turn until it confirms there is a
drive present. (Sometimes it is easiest to do this by
trying a fully-functional MMC card in the MMC slot
first so you can confirm which drive letter it is.)
(NB. It will always be labelled as a [Removable Drive]
, don’t mistake it for one of your PC hard drives like
[C:] drive, as that could be catastrophic later on!)
At this stage it may give an error message saying
that the drive is unreadable.
By right-clicking on the drive letter, it will provide the
option of formatting the drive.
Select format the drive, and the [Format Drive] dialog
will appear (Double-check again to make sure it not
your [C:] drive!).
There is only one setting to focus on in this page, and
that is to ensure that the FileSystem selected for
formatting is the [FAT] option (not FAT32, or NTFS or
any other option)
(Note: All mobile phones, to my knowledge, and most
cameras (etc..) use the FAT file system (or at least are
compatible with it) on their memory card media.)
Now click on Format Now ( ensure [Quick Format] is
not selected as this will not actually restore the file
system space byte by byte, but only resets the
header information so the drive thinks its empty
again. This may not be enought to solve your
corruption problem.)
The PC will now - hopefully!- chug away happily until
it has restored the memory card space back to its
original configuration (of course, any information on
there is long gone by now!).
If you recieve an error message back from the
[Format Now] request, then your problem may be
more permanent, and not just a software issue. In
this case, it may still respond to a format request in a
different memory card reader or device.
If you believe it to be a failure of manufacture, then
the warranty on the card offers the prospect of a
replacement card, subject to a confirmation of the
fault upon return of the goods.
