Are you sure your camer supports 8 Mb? Check your manual. If you don't have one, download it:

If it is supposet to support 8Gb SC cards, get a microSD card USB reader and insert it in the computer. Can you ree it as Remvoabvle disk?
It the computer won'r recognize your card, it is BAD.
If you can see it, try to format it to FAT32
Again, if can't, card is BAD

No problem. Simply put your microSD into an adapter and use it. Most microSD chips come with the adapter. I have a drawer with about 20 in it. You may have to format it to FAT32 if it isn't already.

This may be the formatting type you have on the card. Is it NTFS (better) or FAT32 (not as efficient)?

The 1390t works with microSD cards. Your 8GB card is actually a microSDHC card. While it fits into the slot, it will not work in older devices.
You need to go with microSD cards, 2GB and smaller.

You need to use a microSD card, not a microSDHC card. microSD cards max out at 2GB, anything larger is a microSDHC.

If you have a USB card reader you can open the card in Windows and tell it to format FAT32. That should give you a full format.

If the camera have limitation on memory capacity and this 8GB memory is larger than the limitation, the camera may can't read the memory.
Or the problem came from the formatting process. What kind of formatting did you use, FAT or FAT32? Sometimes a gadget can only read one of this format, FAT or FAT32. Maybe you can try to reformat with different type of formatting. For example, if you have formatted this card with FAT then this time try to format it with FAT32.

Hope this help and be kind to rate this answer.

The 'FAT' file-system uses 16-bit arithmetic, and thus is limited to about 2GB in size.
The 'FAT32' file-system uses 32-bit arithmetic, and thus can easily format an 8GB device.

So, be sure to choose 'FAT32'.

Also:
Click Start
Right-mouse click My Computer
Choose Manage
Click Storage
Click Disk Management (local)
Does the card show a 1.87GB "partition", plus 6.13GB of "unused" space?
If so, then delete that "small" partition, and then create a new partition that "spans" the entire 8GB.
Then, FORMAT that partition.

Format your memory card in PC using FAT (no NTFC or FAT32), then insert it to your HTC and format again. Also do an back up before formatting.

I been at it all night downloading programs and using dos commands, the only way to make it seen by device is useing fat file system, and my winxp will only do fat32. However, my microsd is 8gb, not 4gb. so my problem might be slightly bigger than yours. Mine didn't come with any software, but it was $30, so I got what I paid for. shrug
