SD Card shows corrupt file names

Mike5150 · #1 (**permalink**) 04-11-2010, 09:57 AM

I decided to upgrade my SD card recently, so while shopping around for the best price I found a 16GB micro SD for $20 on eBay. Not realizing it was from China, it took nearly 4 weeks to get here. After getting everything copied over to the new card, I happened to notice the root of my new SC looked normal, but clicking deeper into the file directory I find all kinds of files and folders with names that look like this /½ÅöPJ±.└⌡╝. I tried formatting the card through my phone, and I tried formatting the card with my computer and it keeps doing this. Is the card corrupted or is there something I can do to fix it?

when you reformatted via the computer, did yuo do a quick format, also did it give you the option to change the file system? it should be fat32, not ntfs or exfat.

Yes, I did do a quick format, and used FAT32 with allocation size of 32kb. Sorry for the title, I thought it looked more interesting that way

Thanks for changing it.

mebbe try a full format instead of quick format. i know it takes a while though.

maybe you could try formatting via the phone itself, instead of pc? good luck.

Try running chkdsk on your SD card (via the computer). Once that's done, do a full format again (also via the computer).

The difference between a quick format and full format is that the latter checks every sector and finds those that are damaged. It then writes to the file system to NOT place any data on the corrupted sectors.

I hope you have backups of your files... if not, back everything up now.

here is a windows app i use to format memory cards. it's designed by a subdivision of Panasonic.

extract to windows desktop, run the SDFormatter.exe as admin.. it's a small little app specifically for memory cards.

I tried the full format, and I tried running chkdsk before and after the full format. Chkdisk found nothing wrong with the card, and neither did the full format. I would think that if the card was corrupted that Chkdsk would at least find it right? I'm trying the sdformatter program now, what is the "format size adjustment" option? Should that be on or off? Any other ideas?
