Default Anyone try a 64gb micro card in the J3?

I have sd card support in my jvc car stereos, so I'm looking at doing dual duty with the J3 and was wondering if anyone had tried this yet. Even if I couldn't use the full extra space due to total file # limit it would still be nice to have a couple of hundred extra albums in my pocket.

Just based on how clunky some of the cowon players are, I suspect it's doubtful. jvc only advertises 2gb support officially but still works with 8, 16, 32 & 64 gb cards, and I was hoping for the same type of situation.

p.s. first post, been reading the forums for a couple of years now but finally broke down and joined.

I believe anything larger than 32GB is no longer SDHC, but rather SDXC.

The J3 only supports SDHC, so there' no point trying a 64GB card.

It's the same with the regular sd cards, the 64gb are sdxc. I can't remember if I did xfat vs fat32 because I lost my first 64gb card a couple of months ago so I can't verify.

A member got a 64 GB card to work in his Clip by formatting it to FAT32. I would assume the same for the J3, though it's use at your own risk.

..And if you decide to try that out, please report back - would be great to know if the 64GB support counts for the J3 too by formatting it to FAT32!

The price difference for regular sd card 64gb (which I know works in my car stereo) is about $110, so I went for the known quantity for now. It may be a while before I can get experimental.

Just a quick update, there was a significant price drop on a sandisk micro card, so it's on the way. I should know one way or the other within about a week.

Thumbs up

SUCCESS!

(Your mileage may vary)

Using firmware 2.26, and a SanDisk 64GB Mobile Ultra MicroSDXC Class 6 card.

I formatted it in fat32, and loaded up approximately 6000 songs on it. I was using sleep mode, so the manually initiated database rebuild attempt did not work, it just blew out the old database for my 32gb card. Turned sleep mode off, shut down. Started and database built with no issues.

Went from approximately 5800 songs with 32gb internal 32gb external to almost 9000 songs with a 32gb/64gb combo.

It seems a little slower starting song 8890, but I guess it's because it's at the end of the card.

If only my car stereo was more generous with its song limit (5000).

Anyone know when 128gb micro sd cards are coming out?

THANK YOU

Now I definitely know what I'm getting for myself after Christmas! I am going to order the exactly same card as the one you use (Sandisk microSDXC 64GB Ultra Class 6) so chances are that it probably will work too. ^^

As for 128gb cards I don't think you should try.. Even from a technical standpoint it wouldn't work as 128gb SDXC cards use the SD 4.0 Specification. Only 64gb SDXC should be compatible with SDHC slots I believe...

Just looked around quickly and I didn't see anything better than $185.00 for the sandisk :/ ... guess I wait for a bit ...

The dealer I have found here in Denmark asks 160$ for it. It's still quite a lot money but I would rather pay for a SDXC card that follows the SD 3.0 Specifications now than wait 6 months and risk that all SDXC cards now is following the SD 4.0 Specifications. This is just a wild guess of course, but I'm still a bit concerned. To quote razorblader (Source):

No problem.

Too bad about the 128gb ones, I was trying to end up with a flash mem pseudo-x7. I'm sure a hard drive wouldn't last long with me, but even 150-160gb is too small for me.

Perhaps the next step would be replacing the 32gb SSD flash drive then? :P

Has Cowon upped the file limit? Last time I checked it was something like 8000 audio files.

(from the manual)

- Number of files and folders recognizable
COWON J3 : up to 12,000 folders / 12,000 files
(music/video file: 8,000 + others: 4,000)
MicroSD card : up to 12,000 folders / 12,000 files
(music/video file: 8,000 + others: 4,000)


16k total I guess. Now that I ordered a d2+ after quokka's success on a 128gb card, I wonder if I'm going to hit a limit or finally switch over to .wav.

Looks like I loaded the card outside the j3 in the SD to microSD adapter (included) and put it in the j3, as pointed out by davide37

http://iaudiophile.net/forums/showpo...5&postcount=10

So loading will be a little more cumbersome than plug in and copy. Sorry for that miss.

Interesting.

I have NEVER been able to get ANY of the microSDHC cards I've bought to be usable when inserted into the micro-to-SD adapter's that come with the micro cards. But that may be because of a problem with the card reader I have, which is part of a Mitsumi FA404M combo-drive. Simply never worked... the light on the drive went on when the adapter was inserted but it just hung.

I ended up buying an IOGEAR GFR209 12-in-1 external USB card reader, which had a microSD slot in it. So I could put the microSDHC card into it directly. WORKED PERFECTLY.

I now use the J3 itself as my "drive" for the inserted microSDHC 32GB card, but initially I did use that IOGEAR reader. Adapters for me never worked.

Anyway, I've not had my hands on a new 64GB SDXC card yet to play with, but if I did I would plan on using that same IOGEAR USB reader with the microSD slot to format it to FAT32 and then place the card in the J3, and be done with it forever.

Just to mention that I am now using in my J3 a Sandisk microSDXC 64GB Ultra Class 6, bought it from B&H. I reformated it to FAT32 with gparted (I have a linux/gnome desktop, fairly recent install), and it works like a charm. Already filled up some 45GB in the card. The internal 32GB were already full. Some 13500 ogg files, working really well.
The card came with an adaptor and linux had no problems reading it.

The only glitch I've noticed is related to the UCI. I have a ton of classical music albums with very long "artist" names and browse my collection in library mode, by genre. Using the nice UCI's by kizune (Sense+Leaf) and I started to notice weirdnesses in the album list generated by the the Leaf browser with some albums showing out of order (e.g. one of my Rachmaninoff shows in-between two Bartok albums). I guess the problem is with the UCI.

Here's an excellent opportunity to wash away all confusion and ambiguity about the "file number maximum limit" subject.

The Cowon user manual claims 8000 music files plus another 4000 "other" files, on BOTH internal and external storage. That would suggest a maximum of 8000+8000=16000 music files in total.

Do you have a more specific breakdown for your own allocation of music files located on the 32GB internal and 64GB external storage drives than just "some 13500 OGG files"?

Thanks.
