SD Card reading problem

Hi Ro Bobo

If it works in the other laptop it seems the issue would be the card readers or computer. Do you have access to another computer with a card reader, preferably a fairly new computer? Moreover,never ever use SD card Adapters for formatting.Always USB card readers as they are more efficient.Generic operating system formatters don’t provide the optimum performance.And,sometimes,can result into SD card death and less picture-saving space.

Full format once in awhile is recommended to prevent possible corrupt files, lengthen the life of the card and achieve the most available space possible.

This tool is compatible with Windows XP and vista however Windows 7 users can run this tool in Compatibility mode for Windows 7.You can also try the HP USB Format tool: Download HP USB Disk Storage Format Tool | PCWorld

Generally, older card readers have problems with newer SD Cards. I see this every Day when I am repairing computers. Try that USB Format tool above see what happens.

Hi Dan,

Thanks for your great reply!!!

I am using the SD card reader embedded in the laptops. Will it be better to use an external SD card reader to carry format, read and write?

Thank you again!

Robo you cam do that, but make sure it is Isn 2.0 or 3.0 so there is no question on compatibility.  If you need more help let me know.

As even the internal reader is most lightly USB then that should be a good solution. Then it should be consistent no matter what your connected to

USB 1.0 has issues with some of the newer SD Cards and Readers.  They have been known to corrupt data and erase data. I have had issues in the past where some of my clients data on their SD cards from their digital camera were either not saving correctly or erasing data on the card. USB 1.0 even has issues sometimes with it's own  version of card reader. Case in point, I  had a gentleman doing astronomical picture processing and he has a picture processing of Saturn and it deleted the processing and original pictures.

They fixed most of the issued in USB 2.0 and above.

Most internal devices are in fact  USB as it's just the simplest way of putting all the stuff from different manufacturers together with some chance of success. I find the USB1 devices to be a bit cheap and awful. I use a Kingston USB3 card reader and obviously get very high read write speeds. Compatibility can sometimes be an issue but more when you are writing Gigabytes of Raw data so I often use smaller block sizes like 64K for 'dd' and the like.

Writing at the very highest speeds can sometimes be problematic and some unexpected compatibility issues can arise.

No point talking in the general other than it does sometimes happen compatibility is obviously an individual problem
