its a bit over the top but it will zap flash media and much else
availble in normal places (but not MU anymore)

If it was sensitive data, I'd recommend Fileshredder first even before the format. FYI: You can format a drive, and still recover the data afterwards.

Formatting does not erase data that's a myth to proper erase data you need to write over it. To proper securely kill old data you should write over it 36 times this is called the Gutman Method 36 passes how ever that would take about 4 days and its what the government and police use.
One wipe over PASS should do the trick for everyday users then do a full format.
So what you do is give the micro card a quick format then use CCleaner to wipe the free space 1 pass will do but if its just a SD card choose the 7 pass method as it wont take long.
Once you have wiped over the free space then do a full format I guarantee nobody will recovering anything in a hurry.
Or you can use AVG tune up also.
here's a pic to show where the settings are.

With flash memory I found a format then changing the file system a couple of times was enough to prevent "basic" recovery programs recovering data (i.e. Piriform's Recuva and SanDisk's RescuPro). Though I have been meaning to retry it with those on Hiren's boot disc, I've not actually got round to it yet.
For mechanical drives a single pass of the Secure Erase method takes a few of hours for multi-terrabyte drives, and is as secure enough that the only theoretical method of recovery is via magnetic force microscopy (MFM). However, even microscopic recovery is supposedly impossible on today's high density drives: http://www.vidarholen.net/~vidar/overwriting_hard_drive_data.pdf

Thanks to all that have posted, I have run it through that panasonic delete thing and it secure erased, took about 40 minute, I have formatted it and formatted it all though I'd like to if I get the chance run it through some data recovery software to see if there's any thing on there at all, maybe in the boot sector or the like.
How ever I'm quite happy that it has wiped it clean but I'd like to check.
I can only format this in FAT32 and not NTFS, but can't remember if SD cards can only be formatted fat32 and not ntfs....
Thanks again.

Just tried with GetDataBack. Empty but previously used FAT32 formatted card, quick format to NTFS then back to FAT32, the photos were recoverable. To be honest, it was to be expected.
I'm able to format my SD cards and thumb drives to NTFS
I wonder why I can't format it too NTFS, ?!?! all though this item is selling now and will be sold in the morning, I'd like to think that there is no getting the data back. should have brought it home and then run the data through the recovery stuff that I have. How ever I was confident that the Panasonic software that I used at the beginning of this thread has sorted it, it did do a few writes and the like, forgot the exact ones it used, how ever it did mention that there was some sort of boot that could not be formatted and I'd have to use some other program.....

You could just admit you are a huge fetish porn addict so anything recovered on the card won't come as a surprise lol

@ POB are the micro SD cards you can format to NTFS or just SD ? I have had a few 8GB micro SD cards and have never been able to format them to NTFS
And Dibbers dont worry about a bit porn m8 and nude photos and stuff, Im sure your sexy as hell, I will look for you on youporn with your cucumber and yoghurt pot lol

It was a normal SD card. Will try a micro SD card when I get home from work.
NTFS is definitely a format option for micro SD too.
Why not just format (non-quick) in windows 7 with multiple passes? My understanding is this zeros the data.
...but since you have resurrected the post...
From Vista there has been an option to zero data but you would need to use the command for multiple passes:
format e: /fs:NTFS /p:2
Replace e: with the relevant drive letter - to do C: or XP and below you would need a Windows 7 System Repair disk.
