without leaving any marks?
The 32GB MicroSD card I purchased in May no longer retains files that are written to it, the files that are on it can't be deleted and no software I've tried can successfully format it.
SDFormatter complains that it is write-protected. Windows XP, HP USB Formatter and other programs are unable to complete a format. My Symbian phone appears to successfully format the card, but when the card is mounted in Windows the old files are still there.
Attempts to rewrite the partition table with EaseUS Partition Master and TestDisk have been unsuccessful.
An HD Tune error scan showed 1.4% damaged blocks and a subsequent scan reported a higher percentage. A surface scan with EaseUS Partition Master shows bad blocks and gets hung up without completing.
Some of the files the card stubbornly retains contain private or personal information and I don't want to apply for RMA until I 'm certain the files are deleted or the card is rendered unreadable.
The manufacturer's tech support suggested wiping it with PartedMagic but that was ineffective too.
Are there any other ways to make it unreadable?
