If you must interface with Window$, you should look at the Debian package ntfs-3g; there is a manual page and a wiki (www.debian.org/NTFS). As an experiment: (1) I used a laptop running Window$7 to reformat a new (FAT32) 32Gbyte SDHC; I used the laptop because it had an internal SD slot. In the format dialogue, I gave the device a label (SDHC-NTFS), and I UNchecked the "quick format" box. It appears that a "full format" is necessary if the file system is being changed from FAT or FAT32 to NTFS. The formatting process took a half hour or longer; thankfully, M$ included a progress bar. (2) I plugged the newly-formatted SDHC into a SIIG "USB Multi Card Reader" (USB2) and then I plugged the cable of the reader into a USB socket (USB2) on a desktop running Debian Squeeze. In a few seconds, a "File Browser" (Nautilus 2.30.1) window opened, displaying the (empty) contents of the SDHC device. With the command "/cat/etc/mtab" I discovered that the SDHC was mounted at "/media/SDHC-NTFS". (3) Using the "dd" command, I created on the hard drive of the desktop an ISO image from a software installation DVD. (4) I used "rsync" to copy the ISO image from the hard drive to the SDHC card. (5) I plugged the SDHC card into the SD slot of the W$7 laptop, but W$7 was unable to access the card; instead, W$7 requested permission to format the card. (6) I returned to the Debian desktop machine and used "mkfs.ntfs" to reformat the SDHC card. (7) I repeated step #4. (8) I repeated step #5, with the same result. (9) I then removed the SDHC card from the W$7 laptop, plugged the card into a card reader (this time, a SIIG "USB 3.0 Multi Card Reader"), which happened to be at hand, and I used the "Disk Utility 2.30.1" to verify that the file system of the card still was "clean". (10) I then plugged the cable of the same card reader into a USB port of the W$7 laptop. The card was recognized immediately, and the ISO image was displayed by Window$ Explorer. (11) As a final check, I then plugged the SDHC card into the SIIG USB2 card reader, and plugged the cable of the reader into the W$7 laptop. Again, the ISO image was displayed by Window$ Explorer. I do not understand why the internal card reader of the W$7 laptop was unable to read the card. A reader which I purchased years ago worked with SD but not with SDHC; however, the internal reader of the W$7 laptop is able to read FAT32 SDHC cards.
