SDHC cards : Not reconised by SD reader?

[fubol]

Hello ,

 

 

 

Last week my uncle bought an 8GB SD(HC) card but when he got home , and tried to put it in the cardreader , it was not reconised by his pc , we tried using an external card reader (also a normal SD reader) but no succes either..

 

 

 

Now he asked me to try on my PC , and so I did 10 mins ago , but yet again , no succes.

 

 

 

Now , I saw that it says : "SD HC instead "of "SD" , is there much different and is there any way to use it? do we have to buy another (external) card reader?

 

 

 

PS. I have no experience with SD cards , but I use one for my digital camera (11megapixels for those who are interested :D ) but can you store other things on it (like videos , programs , games (for carying around) )?

 

 

 

pleas help :)

SDHC has a higher transfer rate and can exceed a certain amount of gigabytes. This is great and all, however, it's not backwards compatible. That means, unless your device specifically says that it supports SDHC, you're going to need another card reader.

If you think that's bad, there will be a 3rd standard, and worse, they each have a common edge.

 

 

 

SD - up to 4GB

 

SDHC - 4GB - 32GB

 

SDXC - 32+GB

 

 

 

There are also possible compatibility issues with SD 1-4GB sizes

 

 

 

A further issue, is speed ranks, normally ranked similarly to the X od a CD-ROM, where 1x is 150kB.

 

Some speeds I have seen a few times:

 

8x - fallback speed

 

32x - best speed of the built-in system reader

 

88x - my best SD card in another reader, falls back to 8x in the built-in.

 

 

 

If you are in the UK, check out the Signalex USB card reader in Poundland. It can carry the card internally (like a somewhat oversized USB stick) and claims to support SD-HC. Not able to verify HC, but it is capable of running my difficult card at full speed.
