Peter H Posted December 13, 2015 Share #21 Posted December 13, 2015 Advertisement (gone after registration) My SanDisk 64GB Extreme Pro 95MB/s has always been formatted with exFAT. exFAT is a requirement on ALL cards that are larger than 32GB. Maybe thats why this specific card has always been considered to be faster than many other (smaller size card, and thus, formatted with the old FAT16/32 formats). What do you mean by "exFat is a requirement on ALL cards that are larger than 32 GB"? Do you mean it is advisable, that you prefer it, or that they all are formatted that way and that there is no alternative? Sorry, but the way you put it makes it unclear.

indergaard Posted December 14, 2015 Share #22 Posted December 14, 2015 What do you mean by "exFat is a requirement on ALL cards that are larger than 32 GB"? Do you mean it is advisable, that you prefer it, or that they all are formatted that way and that there is no alternative? Sorry, but the way you put it makes it unclear. The FAT32 filesystem isn't supported on devices bigger than 32GB. That's why all devices bigger in capacity than 32GB are formatted as exFAT from the factory. This might be the reason why the 64GB cards in specific have been recommended for so long, simply because they use exFAT as the filesystem as default. A 16GB card formatted with exFAT might offer just as quick start-up times I would assume. Link to post Share on other sites More sharing options...
Guest JonathanP Posted December 14, 2015 Share #23 Posted December 14, 2015 Tested 2x Sandisk 16GB 95MB/s cards - they were originally formatted as FAT from the factory, and thats how I've been using them in my M240. I then formatted them one at a time in Mac OS X 10.11.2 to exFAT. Start up times measured by holding down shutter button and switching on, tried several times: FAT: 2.5 - 3 seconds to shutter open exFAT: ~1.5 seconds to shutter open Thanks Andreas for the tip! thats a worthwhile improvement, even with these smaller cards. Reformatting them in camera keeps the exFAT format, so only need to convert them once in computer. Jonathan Link to post Share on other sites More sharing options...

fdotr Posted January 1, 2016 Share #25 Posted January 1, 2016 Cards can be formatted to exFAT in Windows or Macs. However, Macs do something Apple-flavoured. This is from a thread titled exFAt on Mac OS X 10.6.8 in discussions.apple.com "It's a known issue that, depending on how big the drive is, formatting exFAT in OS X uses too large of block (cluster) size that Windows doesn't like. Format the drive from within Windows with a block size no larger than 1024 and you should be able to use the drive on both platforms." My 240 read a Lexar SD card formatted to exFAT in a Mac. Curious if it makes any difference to read time in a Leica. Link to post Share on other sites More sharing options...
rocheung Posted January 2, 2016 Share #26 Posted January 2, 2016 Great info. I just tried to format in my Mac without any stopwatch. The result is obvious. Link to post Share on other sites More sharing options...
jim0266 Posted January 5, 2016 Share #27 Posted January 5, 2016 Advertisement (gone after registration) I'll throw this into the mix: The fastest startup time I was able to achieve, from turning the camera on to being able to make an image, was 1.6 seconds. That was with a Panasonic Gold 8GB card. Time of other cards I tested: 16GB Sandisk Extreme Pro (95MB/s): 1.8 seconds 16GB Panasonic Gold: 1.9 seconds 16GB Samsung Pro (90/60 white card): 1.75 seconds In order to measure the time, as I turned on the camera while holding down the shutter button, I recorded this on video. Using Audacity I imported the files, allowing me to “see” the sound of the “on” switch being turned and ended with the sound of the shutter opening, allowing for a precise time measurement. Formatting the SD Card as exFat seems to be the key. I also tried SD Card Formatter alone and in conjunction with formatting in the camera. That didn’t seem to make any difference. Once I formatted the cards as exFat on my Mac I recorded my fastest start-to-shoot times. The 16GB Panasonic’s start-to-shoot time when the card was formatted only in the camera at the card’s default MSDOS FAT format was 5.2 seconds. Formatting the card first in my computer as exFAT, then formatting the card in the camera reduced the startup time on this card to 1.9 seconds.

Philjh Posted January 10, 2016 Share #28 Posted January 10, 2016 Sandisk Extreme 16GB (60/90mb version) Formatted: Using SD Formatter - Fat32 - 1.8 secs Using Win 8.1 - exFat - 1.8 secs No advantage for me. Link to post Share on other sites More sharing options...
rocheung Posted January 18, 2016 Share #29 Posted January 18, 2016 I am using Toshiba flashair one 16G one 32G on my M240 and M246. I found cannot transfer files after formating in exfat. Wifi can be connected, but seems the Apps on my iphone and ipad cannot access the data inside. Anybody knows why? ThAnks. Link to post Share on other sites More sharing options...
Jared Posted January 25, 2016 Share #30 Posted January 25, 2016 Are you shooting "DNG + JPG?" If you shoot DNG alone there will be nothing to transfer since mobile devices can't read anything but JPG's. It may be unrelated to the formatnof the SD cards. - Jared Link to post Share on other sites More sharing options...

wlaidlaw Posted February 17, 2016 Share #32 Posted February 17, 2016 The Nikon AR-3 cable release fits and works perfectly with the M240 and is very nicely made (be careful you don't get a nasty cheap clone on Fleabay). It has a locking facility. It fits better than Leica's own cable release, which with the altered thread on the more recent Leica shutter buttons, is a bit hit or miss.

edwardkaraa Posted November 13, 2016 Share #34 Posted November 13, 2016 Formatting as exFat, or with SDformatter, produce similar results? Am I correct? Link to post Share on other sites More sharing options...
Joakim Posted November 13, 2016 Share #35 Posted November 13, 2016 I tried to use an exFat formatted card in my M9 but it didn't work. Since using the SDFormatter makes the M9 accept the card again it can't be the same as exFat, at least not on a Mac. On a side note, my Mac thinks that my SanDisk card is a Lexar card, hmmm Link to post Share on other sites More sharing options...
Gregm61 Posted November 13, 2016 Share #36 Posted November 13, 2016 Wow! Absolute result. Only thing at the back of my mind is that is exFAT as reliable as a card formatted by the Leica firmware? Anway, the results Leica M 240 Sandisk 16 GB 95MB/s Startup time with Leica format 3 seconds Startup time with exFAT format 1.5 seconds Thanks you! BTW I discovered before that a slower and smaller SD card (4GB 30MB/S) starts up in 1.5 seconds too with the Leica format Don't know if the smaller size or slower speed made for a faster startup but the guys at Leica Mayfair don't recommend fast, large cards Figure that one out! This mirrors my experience with my M262. Startup time as well as the time it takes the camera to format the card is now a very noticeable half what it was since I formatted my 32GB Sandisk Extreme Pro SD card to exFat. My M9 is on pretty much at once when I turn it on. It's just this latest generation of bodies that seem to take a little extra time to fully power up.

lct Posted November 20, 2016 Share #38 Posted November 20, 2016 On SDHC cards, exFAT did not improve startup nor wakeup times significantly last time i tried. About SDXC cards, SD Formatter formats them in exFAT already so i go on using SD Formatter for both SDHC & SDXC cards anyway. As an aside, rescueing damaged cards proves almost impossible when they are formatted with Sony cameras for some reason. No problem when they are formatted by SD Formatter though so all my cards are now formatted by SD Formatter only. FWIW. Link to post Share on other sites More sharing options...
dugby Posted December 9, 2016 Share #39 Posted December 9, 2016 I am using Toshiba flashair one 16G one 32G on my M240 and M246. I found cannot transfer files after formating in exfat. Wifi can be connected, but seems the Apps on my iphone and ipad cannot access the data inside. Anybody knows why? ThAnks. I use the Toshiba FlashAir W-03 32GB, formatted as FAT32 with the WIFI function working as designed in my M240 (FW 2.0.3.0) After extensive testing, I have found that if this card is formatted to exFAT, the WIFI function ceases to operate as expected. Upon reformatting to FAT32, the card's WIFI function is again usable. ------------------------------------------------------------------------------------------------------------------------------------------------------------------- I also use the Toshiba Exceria Type 2 64GB, formatted as exFAT, which does indeed boot up in 1 to 2 secs in my M240 (FW 2.0.3.0) M240 (FW 2.0.3.0) Link to post Share on other sites More sharing options...
edwardkaraa Posted December 9, 2016 Share #40 Posted December 9, 2016 I formatted my cards to exFat and if there is any improvement, it's not more than maybe 0.5 second, subjectively. Link to post Share on other sites More sharing options...
