jbleonelli Posted September 8, 2014 Share #1 Posted September 8, 2014 Advertisement (gone after registration) Hi everyone, Just bought a Lexar 256 GB SD card and the M Typ 240 does not recognize it. Is it normal? Tried the card on a Canon 5D and it was working without any pb. Thanks for your help! Link to post Share on other sites More sharing options...

thighslapper Posted September 9, 2014 Share #2 Posted September 9, 2014 Probably....... I sincerely doubt Leica supports this size. Are you mad ? This is equivalent to 20x 16gb cards .... and I am hard pushed to fill one of these on a days shooting .... Are you producing full length movies ???? Is the camera constantly on 'C' ??? Multiple smaller cards is a much safer strategy .... and this is one area where bigger is not necessarily better ..... or faster ..... Link to post Share on other sites More sharing options...
jaapv Posted September 9, 2014 Share #3 Posted September 9, 2014 It is indeed an astoundingly unusual size. It is very hard to imagine a reasonable use for it - I use 8 and 16 Gb.... Link to post Share on other sites More sharing options...
lct Posted September 9, 2014 Share #4 Posted September 9, 2014 The OP's question was not to know if he was right or wrong in his purchase but if the Lexar 256GB card can be used on the M240 or not. The M240 instructions manual (page 250) say: "SD cards up to 2 GB / SDHC cards up to 32 GB / SDXC cards" which means that there is no limit for SDXC cards implicitly. Did you try to format your card with SDFormatter? Just curious as i have no experience with this card. 64GB is more than enough for me but i don't do video at all.

01af Posted September 9, 2014 Share #5 Posted September 9, 2014 Just recently I bought a SanDisk SDXC Extreme Pro 64 GB card, and the M (Typ 240) happily accepts it. In particular, start-up time has improved slightly but significantly; with the new SDXC card it's now just under two seconds. With my older SDHC 32 GB cards, it used to be between three and four seconds, even after having formatted them with SD Formatter 4.0. And if a device using SD cards is compatible with the SDXC standard then it shouldn't make a difference whether the card's capacity is 64 GB, 128 GB, or 256 GB. So, jbleonelli, probably there's something wrong with either your card or your camera. Maybe you should try re-formatting your existing card with SD Formatter 4.0. Or try another SDXC card in your camera. Or try your card in another M (Typ 240) camera. By the way, if using an older computer running Windows XP then make sure it has been updated to recognise exFAT which is the file system used with SDXC cards. A computer unaware of exFAT won't see any data on SDXC cards. In this case, DO NOT re-format the media or it will get damaged! Link to post Share on other sites More sharing options...
01af Posted September 9, 2014 Share #6 Posted September 9, 2014 Multiple smaller cards is a much safer strategy ... To the contrary. One big card actually is the best strategy. The more cards you're juggling, the more likely you will lose one of them, step on one of them, or confuse them and re-format and overwrite the wrong card (has happened to me, thank you very much). User error is much more dangerous to your data than hardware failure. Moreover, when using 20 cards then a hardware failure is 20 times more likely than when using only one card.

jaapv Posted September 9, 2014 Share #7 Posted September 9, 2014 Advertisement (gone after registration) Well, yes, Olaf, it can be argued both ways, I prefer 16 GB max and back up to a laptop or image tank, but 256 GB?, as the loss would be 20x larger as well. It is not long ago that that was a large Hard Disk.... Anyway, whatever the rights or wrongs, the camera should be able to accept it. I wonder if the OP formatted the card in his 5D, if so, a reformat in the M (or to exFATin the computer first, if the camera does not see it at all) might clear the problem.

01af Posted September 9, 2014 Share #8 Posted September 9, 2014 ... the loss would be 20× larger as well. Only if the card is actually full, which it won't be most of the time. It is not long ago that that was a large hard disk ... It is not long ago that people using 8 GB cards were considered fools for taking the risk of using those outrageously big cards rather than, say, a couple of 512 MB cards ... Moreover—would you really recommend to refrain from using, say, 2 TB hard-disk drives and to use a dozen 512 GB drives instead? No? Then why so with memory cards? I wonder if the OP formatted the card in his 5D, if so, a reformat in the M (or to exFATin the computer first, if the camera does not see it at all) might clear the problem. The Canon EOS 5D and EOS 5D Mk II have no SD card slots in the first place; the EOS 5D Mk III is SDXC-compatible. So formatting the card in an EOS 5D Mk III should be fine. Of course, it still is a good idea to re-format any memory card in the very camera it's going to be used in. Link to post Share on other sites More sharing options...
lct Posted September 9, 2014 Share #9 Posted September 9, 2014 Better lose a 8GB card than a full 64GB folks. Not a good thing to put all one's eggs in one basket. I use only 8 or 16GB cards when shooting for my job personally. YMMV. Link to post Share on other sites More sharing options...
pop Posted September 9, 2014 Share #10 Posted September 9, 2014 I do not think the comparison between fixed disks and SD cards very useful. Disks have built-in redundancy and error detection. Operating systems can detect when disks start failing, hopefully before much damage has been done. In the case of a hardware failure, it is not all that likely that you will lose all data stored on the disk. None of these apply to SD cards. I have lost more SD cards due to technical failures (2) than due to operator error (0) so far. Touching wood. Even so, I use RAID systems to keep my critical data on fixed disks or else some very frequent snapshots. For my personal usage pattern 16GB is the optimal size for storage cards to be used in the M. It's largely a matter of opinion. Refer to Mark Twain re keeping all eggs in one basket. Link to post Share on other sites More sharing options...
colonel Posted September 9, 2014 Share #11 Posted September 9, 2014 When I am on holiday I use the biggest SD cards I can. I backup the pictures each night to a laptop and send to dropbox or flickr the important pictures to backup, so the card therefore acts as an additional backup since I don't erase cards away from home. Having a large card means I rarely have to use more then one for an entire holiday, and definitely not within a day unless I am taking video. Link to post Share on other sites More sharing options...
wattsy Posted September 9, 2014 Share #12 Posted September 9, 2014 I wouldn't worry, it's a Leica – the shutter will probably die before the card is filled. Link to post Share on other sites More sharing options...

In the case of a hardware failure, it is not all that likely that you will lose all data stored on the disk. None of these apply to SD cards. Actually, SD cards have micro-controllers that do error detection, bad block flagging, write tracking, and so-forth. In fact, most of them can be hacked, and counterfeits are always hacked. They are very sophisticated in error correction because they have to be: something like 80% of the read/write bits are corrupt at the manufacturing level, but the flash chimp is used anyway.

LocalHero1953 Posted September 9, 2014 Share #16 Posted September 9, 2014 User error is much more dangerous to your data than hardware failure. I like this. I would extend it to say that the risks to your data, in decreasing order of importance are (1) user error (2) hardware failure (3) burglars, house burning down etc. But if you read forum threads about data security, you'd believe that the order is the other way round. Ah, well, human nature. Link to post Share on other sites More sharing options...
LocalHero1953 Posted September 9, 2014 Share #17 Posted September 9, 2014 If your SD card is so big you only take it from the camera to plug it into the PC, you're less likely to lose one than while managing half a dozen small ones while travelling.

bocaburger Posted September 9, 2014 Share #18 Posted September 9, 2014 I was fine when there were 36 exp on a roll. I use the same 2GB cards I used with the M9, and M8. In fact with them I had to shoot RAW so the capcity was more limited than it is on the M240. Carrying a slew of them is no problem at all. I have a number scratched in the plastic so I know which is which. It's an ingrained habit to flip the lock switch when I pull a full one out. Never lost one, stepped on one, swallowed one, or any other scenario one could contrive to support the assertion bigger cards are somehow less of a risk. If someone gave me a couple larger cards I'd use them but I'm not about to go buying any as long as the one's I've got still work. Link to post Share on other sites More sharing options...
01af Posted September 9, 2014 Share #19 Posted September 9, 2014 Disks have built-in redundancy and error detection. [...] None of these apply to SD cards. Even so, I use RAID systems to keep my critical data on fixed disks ... Certainly you are aware that RAID systems increase data availability but reduce data security, aren't you? For my personal usage pattern 16 GB is the optimal size for storage cards to be used in the M. So it is for mine ... most of the time (but not always). Still, I bought a 64 GB card because SDXC cards don't come in smaller sizes. And I wanted an SDXC card for the increased speed (i. e. shorter start-up time in particular). This 64 GB card now is so huge I can hardly imagine why someone would want an even bigger card ... but then, I hardly do video. Anyway, a 256 GB SDXC card should work just fine—so no, it is NOT normal that the M (Typ 240) doesn't recognise it. Link to post Share on other sites More sharing options...

However, the resulting reliability when used in cameras is not quite comparable to that of the hard disks in computers. Link to post Share on other sites More sharing options...
