I wondered if anyone could help?
I've purchased a 16Gb micro SD Sandisk card for a MP3 player. I
purchased one with a SD adapter because I don't have a micro HC
compliant reader. I put the card in the player and was able to
files onto the card via Windows. But I got tired of copying my
stopped after copying about 6Gig. But what ever I do now I
any more. Furthermore, I can't destroy it either. If I run
press 'o' for a new partition table the linux machine sits there
minute or two and returns me to the prompt. Then when I list
'fdisk -l' it's vanished. I've been reading forums about
and my head is spinning.
What logs or switches should I observe what is going on?
I found ufiformat a low level format tool but it refuses to
SD as a floppy, obviously because it's not. So is there another
BTW: There's a HP USB storage format tool that doesn't touch it
on the Windows platform. This is why I thought I've have better
I've tried mkfs.vfat again it returns me to the prompt after
minutes having not touched the file system on the card.
I could touch a test file and rm that file. But If I attempt larger
file transfers the device craps out with read write errors and the
device has vanished.
As Micro SD's don't have a locking switch how on earth do I get
thing formatted and start again?
Something has had some effect as it's currupted something as the
player just crashes when I attempt to use it with the card
I'm waiting for a new card reader but I don't think that's going
any difference because I've tried to get my phone to format it.
Victor Stream too. None of them can touch this card.
Well I have destroyed partition tables with dd before now but
have a clue on whether this would help in this situation.
Any help would really be appreciated.
