SanDisk 4GB MicroHC card says card is dirty clean or format.

The LG620g works with microSD cards. Your 4GB card is actually a microSDHC card. While it fits into the slot, it's electronically incompatible and will not work in this phone. You need to use microSD cards, 2GB and smaller.

1. Be sure that the device you are using the 4GB micro SDHC card for,
is able to use this type (HC=High Capacity) of memory.
2. Check the memory card is working well on a notebook / pc with an adaptor
and/or a SD-cardreader.
3. Format the memory card and re-check.

my memory card is locked it is micro Sd 2 gb how can i open it .i dont now how it is locked ,my set is N95 nokia .

it should work fine. maybe the memory card is faulty.
have you tried the card in anything else to check that it works properly?

You shouldnt have to format it.Though it is possible. first check and make sure the drive is not locked. There should be a smll switch on the side of the sandisk. Second be Sure your device supports HC cards. Read This tip carefully If its your computer and it has a HD compatible slot insert the drive, open my computer , you should see its new icon as a drive. Right click on the drive and select Format from the list. But, as a reminder if your device supports the HC or XC format drive, it should work without a Format. Hope that helps ya, Gurvy

your samsung Gravity 2 wont read the HC format, there is not much you can do sorry. the SD HC is a newer format for devices in the last year or so. Older devices will not accept the HC format cards. I did the same thing! And im in the business, easy mistake. Keep it around though you'll use it soon, just not in your Samsung. Gurvy

You problem is most likely to be the fact that your micro chip is a HC chip. HC chips have a new program that is not backwards compatible to regular sd host ports. This is a simple fix, however. If you don't trust downloading programs for it on the internet, just go to target or walmart and get a USB SD card reader, and a SD adapter if you don't already have one. The usb adapter should only be like $10 at most.

THe HC chip set for SD's and micro SD's have different programming in them and are unfortunately not backwards compatable with a standard SD host port. For you laptop, I reccoment getting a USB SD chip adapter. They're only like $6-$10 depending upon the brand. For your phone, however, I reccomend you take it back to the store for a trade-in on a standard SD chip, or for a complete refund so you can buy one from a store that carries standards.

I guess you put the SD adapter into the card reader right out of the box? You first may have to partition/format it after unpacking it. Under WinXP I can recommend an utility "DiskPart" which you can start from the command prompt (Run... -> cmd). For further instructions (if it sounds to you to be the problem ) contact me again.
