4gb sd card not format problam format uncomplet

My 4gb memory card SD showing 30.1mb and can't formatted it{Transcend}

The DA5 works with SD cards. Your 4GB card is actually an SDHC card. While it fits into the slot, it is electronically incompatible and will not work. You have to use SD cards, 2GB and smaller.

The DX7630 works with MMC and SD cards. Your 4GB cards are actually SDHC cards, not SD cards. While they will fit into the slot, they are electronically incompatible and will not work. You need to use SD cards, 2GB and smaller.

You haven't told us what kind of camera it is, but I can guess at the problem. There are two possibilities.

1. Your camera will only read SD cards, not SDHC cards. You've just bought a new memory card, not noticing that it was SDHC. The new cards don't work in your camera, not because they or the camera are broken, but because they're not compatible.

Cards up to 2Gb are generally SD. Cards over 8Gb have to be SDHC. 4Gb cards can be either SD or SDHC, but are almost always SDHC because they're cheaper. (I would avoid the rare, expensive, and problematic 4Gb SD cards.)

Your solution is to go find a 2Gb card, and be extra sure that it doesn't say "SDHC" on it. (If it does, it probably means that they made a 4Gb card, but there were some error locations and so they disabled half of it and packaged it as a cheap-brand 2Gb.)

2. You formatted the card NTFS, whereas the camera needs FAT32. You can format the card using Windows, but there is a complication: Windows defaults to "NTFS" when formatting, but memory cards normally use FAT32. Before you attempted this, you should have connect the card, and checked the 'properties' on the drive that appears. It probably said "FAT32". In this case, you could have gone ahead and formatted the card, but be sure that you chose "FAT32" from the drop-down list. If you format it NTFS, your camera won't be able to read it!

In this case your solution would be to format the card again, but using the FAT32 format.

You might find it useful to check your camera on dpreview (dot) com, and see if the memory card type is shown as just SD or SD/SDHC.

The official oprating systems of the HX4700, WM2003 and WM5, do not support SDHC card format. Since most 4Gb "SD" cards are in SDHC format (check the label on your card), the file format of your card is likely to be incompatible with the PDA. Get a 2Gb SD card, or go for a Compactflash card for 4Gb to 32Gb of storage space.

The Optio S4 works with MMC and SD cards. Your 4GB card is actually an SDHC card. While it fits into the slot, it is electronically incompatible. You need to go with cards 2GB and smaller.

The DX7590 works with MMC and SD cards. Your 4GB card is actually an SDHC card. While SDHC cards will fit into SD slots, they are electronically incompatible and won't work. You need to use SD cards 2GB and smaller.

You can't. The Z612 uses SD cards. Your 4GB card is actually an SDHC (Secure Digital High Capacity) card and is incompatible with SD devices.

For SD cards (2GB and smaller), you'll find the Format operation in the Setup menu. Press the Menu button, then use up/down to select the wrench, then press OK.

Hi,
Your Kodak LS743 camera is built to use the SD memory card standard - which only goes up to 2GB. Any SD card over 2GB is a new format called SDHC (high capapcity) and isn't compatible with the previous format. This is why you can't use your 4GB card - you have to use a 2GB card.

I believe sandisk makes a special program to format their cards
