CHDK and Nikon Partitions on Same SD Card?
« on: 20 / September / 2016, 14:05:40 »

Hi,

Would like to divide a 64GB SD card between my CHDK and Nikon Cameras ( thought 32GB ea).

Searched and found Multi partition support A590 IS https://chdk.setepontos.com/index.php?topic=2798.5;wap2  but not much more.

Check wiki and found Using SDMinste to Create Dual Partition SD cards http://chdk.wikia.com/wiki/Using_SDMinste_to_Create_Dual_Partition_SD_cards but recommends using Stick http://zenoshrdlu.com/stick/stick.html 

Did some checking and found "STICK can't currently reformat exFAT cards as FAT32 or repartition them into FAT16 and FAT32 partitions, at least not reliably."

Appreciate suggestions!

Thanks

Ken

I really messed up the different font cut and paste.


How can I make everything the same?


Thanks

I have no idea what Nikon cameras do with partitioned cards, but I would suggest just buying more cards, UHS-1 32 GB cards are down to about $10.

Use the plain text editor (pointer in brackets icon at the end) and edit the tags to taste. You can set this as the default in your profile.

Is there any reason why the Nikon camera can't use the same partition as the Canon?

Even if you could create two partitions and use one for CHDK and the other for NIKON, I think you'd have real problems transferring photos to your computer if you are using Windows. Windows will only let you see the active partition - and its a real pain to switch.


Although STICK cannot reliably reformat EXFAT cards, it's relatively simple to reformat as FAT32 and then use STICK (you'll need to use a non-Microsoft app to do this to 64GB cards though).

Thanks everyone for your comments!

Zeno,  "I think you'd have real problems transferring photos to your computer if you are using Windows. Windows will only let you see the active partition - and its a real pain to switch"  Thanks for mentioning Did not even consider this!

"it's relatively simple to reformat as FAT32 and then use STICK (you'll need to use a non-Microsoft app to do this to 64GB cards though)."

Can you or anyone else recommend an app to do this?

Waterwingz,  "Is there any reason why the Nikon camera can't use the same partition as the Canon"  I do this all the time and have not had any problems yet.

reyalp, "Use the plain text editor (pointer in brackets icon at the end) and edit the tags to taste. You can set this as the default in your profile."  Thanks for info!  Is there a wiki that explains all the forum options? Googled using keywords  chdk wiki forum options
https://www.google.com/search?q=chdk+wiki+forum+options&ie=utf-8&oe=utf-8 but did not find anything relevant.

Here's one app that will do the job of formatting a 64GB card as FAT32. There's another one here

zeno,Thanks for the links to 1. Windows GUI version of fat32format   http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm
2. Fat32Formatter version 1.1  http://tokiwa.qee.jp/EN/Fat32Formatter/
Since posting I did some checking and found

3. Smartdisk Fat32 Formatter utility Could not find the "Official DL site"
4. Free SD Formatter  ??? got from http://download.cnet.com/Free-SD-Formatter/3000-2094_4-76457819.html  which says "Editors' Note: Download.com has chosen not to provide a direct-download link for this product and offers this page for informational purposes only."
5. MiniAide Fat32 Formatter  http://www.fat-32-formatter.com/ and  http://download.cnet.com/MiniAide-Fat32-Formatter/3000-2094_4-75701815.html  It has highest ratings at cnet.
Maybe some more?
Hope someone at CHDK Forum has tested these and possibly others.
Ken

Another option to format and partition cards would be using e.g. gparted in a linux VM or live CD/USB. This isn't user friendly, but IMO the user friendly solution is spending $10 a pop on newegg, amazon etc to get dedicated cards.

The forum runs SMF, it's not unique to CHDK. Generic SMF documentation should be available from google.

reyalp,


"The forum runs SMF, it's not unique to CHDK. Generic SMF documentation should be available from google"  Thanks Ged and found "Welcome to the SMF Online Manual" http://wiki.simplemachines.org/smf/Main_Page

"Another option to format and partition cards would be using e.g. gparted in a linux VM or live CD/USB. This isn't user friendly..."  At this time want to stick with something that is "Beginner Proof" (also called Idiot Proof).

Since posting checked SD wiki https://en.wikipedia.org/wiki/Secure_Digital  and found "Risks of reformatting[edit] Reformatting an SD card with a different file system, or even with the same one, may make the card slower, or shorten its lifespan. Some cards use wear leveling, in which frequently modified blocks are mapped to different portions of memory at different times, and some wear-leveling algorithms are designed for the access patterns typical of FAT12, FAT16 or FAT32.[98] In addition, the preformatted file system may use a cluster size that matches the erase region of the physical memory on the card; reformatting may change the cluster size and make writes less efficient.SD/SDHC/SDXC memory cards have a "Protected Area" on the card for the SD standard's security function; a standard formatter may erase it, causing problems if security is used. The SD Association provides freely-downloadable SD Formatter software to overcome these problems for Windows and Mac OS X.[99] The SD Formatter does not format the "Protected Area", and the Association recommends the use of appropriate application software or SD-compatible device that provides SD security function to format the "Protected Area" in the memory card."


Which is why I am interested to find out about others experience doing this!
