Can't format Hyperdrive in WinXP
To be truly portable, formating with the WinXP NTFS will likely mean it won't work in a lot of computers. Therefore, the manf have programmed the format in the firmware for FAT32.
Don't know what the big deal is with the formating in WINXP. I just installed a new hdd in my Hyperdrive HD80 copied the Format file downloaded from the website from my PC onto an xD card, followed the instructions on page 45, followed by the page 16, 17, 18 instructions and the drive is formated. Simple.
As far as wanting to be able to format the Hyperdrive in WinXP this is similar to the desire to want format a memory card in a card reader, but almost all recommendations are to format it in the camera to be safe. With the Hyperdrive it's a similar situation. It's usually better to use the format software provided by the firmware in the device used.
