Tip & How-To about Cell Phones


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...

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.

hi, i have the conon 7D with a sandisk memory card. i am a photographer and i just did christmas pictures today for a family. when i got home i tried to put them onto my computer and the computer told me to reformat my disk because it cannot read it. when i clicked reformat, it said that all my pictures would be deleted if i reformatted it. i cannot loose these pictures for anything! im sure you understand. when i put the disk back into my 7d it says to reformat it too. then it shuts off. could you help me figure out whats going on?

It sounds as if your SD card has failed. It may be physically (electrically) damaged. Do NOT put the card in your camera any more, as it could make things much worse.
You may be able to use a disk recovery program to get some or (hopefully) all the files off of the card. Be patient when using any programs like that - they can take several hours or even a couple of days to get the data off of a bad card.
If you are linux savvy at all, you can use the program "ddrescue" to recover the files. It may also work on a Mac in the commandline.
Another possibility is that the card is physically ok, but the filesystem is corrupted. Using a filesystem repair program could work in this case, such as "chkdsk" on Windows, or "fsck" on Linux or Mac.
I had the same thing happen with a 4GB Sandisk SD card back in May and was able to recover 95% of the data using ddrescue. My card was electrically damaged and had to be replaced.
There are also disc recovery companies that will do data recovery from a damaged or corrupted card, but they are quite expensive ($500-$3000, depending on difficulty of recovery).
I do it sometimes for others for reasonable. www.ruelphoto.com
I will also assist you in any way I can and have time for.

Engine stalls on any speed, day or night. Replaced PCM, Ignition Coil, MAP Sensor, Ignition Switch, Crank Sensor and much more. Any ideas?

Its always a good Idea to check and clean the MAF (mass air flow) sensor when you have symptoms like these use electrical parts cleaner and a tooth brush be carefull it is a fragile piece, If you already done this, check the spark plugs to see if they look kind of lets say frosted over this means your cylinders are running hot, if they are check your catilytic converters by going on a 5 to ten mile test drive to see if they turn cherry red letting you know there plugged, make sure temperature sending unit is correct and its not running hot-only if spark plugs show excessive heat. Also a thing to think about is people always like putting high performance stuff in like spark plugs, but for an average car the do no good and have a lesser life in milage, just replaced some bosche high end plugs in a 4 runner that was stumbling consantly put the regular 1.99 champions in it and it quit. the high performance plugs have an extremely small surface area that wears out or corrodes fast causing driveability problems. theres some other thing that could be wrong like a intake vacum leak that can be tricky to find but these are some good checks that can cause these symptoms without spending money.
