Formatting 16GB microSDHC

I have a 16GB microSDHC for my cell phone. A few days ago, my Motorola phone stated I needed to format the card, even though I had 18 movies and over 1000 MP3’s on it. I formatted it and it changed it from 16GB to 4GB. Is there a flash card format program to reinstate the original value. Killdisk did not help.

Hi,[QUOTE=tom51;2501441]I have a 16GB microSDHC for my cell phone.(…) I formatted it and it changed it from 16GB to 4GB.[/quote]Have you verified, your phone supports that kind of memory card?

Is there a flash card format program to reinstate the original value. Killdisk did not help.

Edit:

Many previous old cameras and portable devices do not work if the card is formatted as FAT32 or NTFS file system. One of the following errors may occur if your device does not support FAT32 or NTFS:

  • Error message asking to re-format the flash card.
  • Error message that the flash card is not formatted.
  • Error message indicating that the card is anomalous.

To resolve the above error, backup your data and reformat your memory card in FAT file system.
If the error persists, re-format the memory card using your camera or portable device.
