From: M on 12 Feb 2010 19:54 See this link about formating SDHC cards to FAT16 or 'FAT' as opposed to 'FAT32' http://uk-mkivs.net/forums/p/216666/2212312.aspx#2212312 I have used a 4GB SDHC card in a RNS-310 sat-nav - music system. The RNS recognises $ gb capacity on the card (only when it was formated in FAT16 or 'FAT' it was not recognised when formated as NTFS or FAT32 Werner \Menneisyys\ Ruotsalainen [MVP - Windows - Mobile Devices] wrote: Strange - FAT16 has always been supported, from WinCE 1.0. 11-Oct-07 Strange - FAT16 has always been supported, from WinCE 1.0.

I know the HTC Touch supports them (well, Micro-SDHC), as I currently have one in my device :) But you're right, if you have a SDHC card with a Fat32 file system and your PPC can't read it, it's likely because the PPC doesn't support SDHC. -- --------- Scott Seligman <scott at <firstname> and michelle dot net> --------- Strange, isn't it?

Actually the OP didn't seem concerned about FAT32. He was asking about FAT16 to allow compatibility with a car stereo. I imagine that means the car stereo takes SD cards, but only reads FAT16? First I'm not sure FAT16 supports 8G...does it? Second, I would guess that a stereo that only supports FAT16, wouldn't support SDHC. It's fairly new. newer than FAT32, and way newer than FAT16. Third, if the stereo actually supports an external USB drive, and that is the connection approach, it wouldn't matter what file system is on the Touch, only that it can be configured as a USB drive. Don't know if it can or not, but it would be unusual if it could. Most WM devices can't. -- Sven MS MVP Mobile Devices "Scott Seligman" <seligman(a)example.com> wrote in message news:feh778$2lq$1(a)panix5.panix.com...

Does a formatting utility exist which allows a FAT16 format on larger disks? Or is there some kind of hack for the standard Window/DOS utilities? Is it possible to partition an SDHC card so that a 2GB partition can be created and thereafter formatted in FAT16? Is it possible to compress the disk so that it is only 2GB in size? Is there any way on God's earth that my SDHC card can be formatted to FAT16?

The only way of sing it is creating a 2G partition on it and using it. Is your player able to handle multiple partitions on a card? If it isn't, then, you will only have access to the first 2G one. -- -- Werner "Menneisyys" Ruotsalainen - Microsoft MVP - Windows - Mobile Devices Please see the Pocket PC Mag Expert Blog (including mine) at http://www.pocketpcmag.com/blogs/ - you will definitely like it. <ryanwpenfold(a)gmail.com> wrote in message news:1192016770.396975.12390(a)57g2000hsv.googlegroups.com...

I have one gps as an example plus have run into a few other devices over the past few years so I think this is Rype's blockade. Windows (on the desktop) maintains both fat16 and fat32 tables on cards... not sure about the current state of windows mobile, but the early versions only created fat32 entries on the ppc... i.e. a memory card's "My Documents" folder created on a ppc would not appear in a dos command window when the card was accessed via a windows pc using a card reader. y'know... the stuff that keeps us on our toes ;-) Beverly Howard [MS MVP-Mobile Devices] On Wednesday, October 10, 2007 11:14 AM Werner \Menneisyys\ Ruotsalainen [MVP - Windows - Mobile Devices] wrote: Windows Mobile has had FAT32 support since 1998 (that is, WinCE 2.0).

I understand the lure of doing it "just because I can". But you're only attacking one end of the problem. How do you know that your car device can play a NON-STANDARD format card? Does it support SDHC at all? Sometimes scaling back your expectations is the rational thing to do. If you drive 24 hours a day and use a 2gig card, you'd have the annoyance of swapping cards every day and a third. If you don't drive for a living, 2gig can last a very long time. -- Return address is VALID!

From: Beverly Howard on 12 Feb 2010 20:04 What is the capacity shown when you format in FAT or FAT16? It has been my understanding that FAT would be limited to a max of 2GB Beverly Howard
