See http://en.wikipedia.org/wiki/Serial_ATA Did you stop learning about the technology once you learned enough about DOS to do what you wanted? A lot of what you post here seems to be based on 25 year old ideas about how this stuff works. The technology has progressed a bit, and you seem to be making assumptions that may not be true for current hardware and OSes. > When I try to format very large SD chips with DOS; the software just gives > up.

And it's not clear why you would *need* to format an SD card of any size. Depending on volume size, they come formatted as FAT16 or FAT32. I've formatted them for other reasons, like using a Linux ext3 file system or NTFS. I put the card into an SD adapter and do the format from my desktop machine. It's quite quick, thanks. > cheers > DS.. ______ Dennis https://plus.google.com/u/0/105128793974319004519 ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
