Jeni, Looks like Windows corrupted the NTFS. Although NTFS is better than FAT as they say, It has major problems on the low level. Try to put the card in the same Windows machine. Use the same profile you used when you tried copying the files in the first place. Then, try to do a complete format on the card without enabling compression. Right click on the drive letter and make sure under properties the security tab has everyone in it. It is a Windows profile if you have XP Pro or any other Windows greater than XP with an edition higher than home. Then, use your phone or MP3 player to wipe the card. I hope those help. If not, feel free to e-mail me off the list if the members do not want to cover Windows on here. At this point, it looks like a file system problem, but it could also be the device itself. You have to isolate the possibilities one by one. -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of Georgina Joyce Sent: Monday, March 22, 2010 6:19 PM To: speakup at braille.uwo.ca Subject: Pulling my hair out over a micro SD Hi 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 copy files onto the card via Windows. But I got tired of copying my oggs so stopped after copying about 6Gig. But what ever I do now I can't add any more. Furthermore, I can't destroy it either. If I run fdisk and press 'o' for a new partition table the linux machine sits there for a minute or two and returns me to the prompt. Then when I list devices 'fdisk -l' it's vanished. I've been reading forums about Sandisk cards 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 identify the SD as a floppy, obviously because it's not. So is there another tool I need? BTW: There's a HP USB storage format tool that doesn't touch it either on the Windows platform. This is why I thought I've have better luck on linux. I've tried mkfs.vfat again it returns me to the prompt after several 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 this thing formatted and start again? Something has had some effect as it's currupted something as the mp3 player just crashes when I attempt to use it with the card inserted. I'm waiting for a new card reader but I don't think that's going to make any difference because I've tried to get my phone to format it. My Victor Stream too. None of them can touch this card. Well I have destroyed partition tables with dd before now but wouldn't have a clue on whether this would help in this situation. Any help would really be appreciated.
