HP 50g & SD Cards: Performance, Format, Notes

[JDW]

Bob,

Thank you for your reply.

But the SD card in question has never been partitioned, ever. I am speaking about my 256MB SD card. And as I said in my previous post, I used a Win8 PC today to format it, but still when I insert it into the 50g, I cannot delete things off it, nor can I format it via the 50g.

But for the sake of formatting it again on my Mac, I opened the Terminal and typed the following:

diskutil partitiondisk /dev/disk3 1 MBR "MS-DOS FAT16" "NONAME" 0B

That formats it FAT16 with no partitioning at all. But again, when I put the card into my 50g, I can view the hidden file content, but I cannot PURGE any of those files, nor can I FORMAT the card within the 50g.

So I then went back to the Terminal and used the following line to format it FAT32 (instead of FAT16):

diskutil partitiondisk /dev/disk3 1 MBR "MS-DOS FAT32" "NNN" 0B

But I still cannot PURGE files or FORMAT the card when that SD is placed in my 50g.

I then put tape on both sides of my SD to make absolutely sure all indentations in the card are covered. Still, I cannot PURGE or FORMAT.

I'm going out of my mind!!!
