startup time

marcusgi · 06-14-2012, 22:30

So something I happened to notice with my C2. My D2+ boots up in about 15 seconds and my C2 takes about 35 secs? The D2+ has class 6 sdhc card in it, the C2 is a microsd class 4. Class speeds are more for write, not read. My guess is that the reader can't even read as fast as either card can produce.

It stays on my C2 version 1.17 for almost 12 seconds before it even starts to read the SD card. They both have the same songs on them, about 40gigs. Not that 20 secs is a long time to wait, but you would think that a newer device would boot faster, not slower.

first, clean up your tags if you havent, remove un-needed advanced/extra/extended tags, only leave what you actually need, this shortens db refresh drastically.

as to card speeds, i have a 32gb class10 and when i tested identical files on a class 2 and 6 card as well as my class10, the class 10 was alot faster for my c2.

if you are turning the player on and off alot, try using sleep mode rather then powering it fully off, this will allow it to boot almost instantly, the drawback is, if you forget and leave it in sleep, it will drain its battery given some time.

AshenTech,

Alot faster reading (not writing) the Class 10 card? Does it say "SDCard" at boot up for half as long?

AshenTech · 06-27-2012, 22:22

in my case, it was around 9x faster on class10 vs class2 if i remember correctly.

also note: some cards work better with some device then others, just like I have a class6 16gb card that gets class10 speeds

I have also seen class10 cards that worked at class10 or better speeds on/in some devices/readers but in others, they where limited to class4 speeds, yet, other class10 cards worked fine in the same reader at full speed....and the cards worked at full speeds in other readers/devices.

one thing to keep in mind at all times is that some cards just wont work well with some devices, and some devices wont work well with some cards....

thankfully my class10 adata card works great, my class6 kingston 16gb works well in the player as well...but its hit and miss with my 8gb cards, cards made in different countries work differently despite looking the same externally....

note with my 32gb within 400-500 of full, and internal with 144mb free, it takes no more then 25seconds to cold boot the device(just tested 4 times)

another tip/trick you should try is to format the card with the sdformatter (google it), once you do this it SHOULD make it work better, if the cards not been formatted this way, backup the data on the card, format the card, then copy the data back and test, I have seen this drop boot times/refresh times on some devices by a staggering amount of time...specially on my d2+ and fuzes.

biggest tip outside the format is the tagging thing, use mp3tag to strip all but one version of tags.

my suggestion(works for every player I own), use ID3V2.3 ISO-8859-1 strip all other tag types as far as i know, cowon players dont properly read ape tags(may be wrong)

also, removing special charactors is a smart move....keep it simple....its amazing how much cleaning up tags can help on top of formatting your card properly

I should also point out, i have thousands of files on my player between music(internal) and audiobooks(external)

Adata it is then, can hardly beat this price:

AshenTech · 07-02-2012, 12:32

hehe, thats the card I have, paid more for mine, but that was quite some time ago when class10 was pretty new stuff

just make sure to format it with the sdformatter when you get it, then load it up

( ihave over 6k files on my card alone, I checked earlier today!!!)

AshenTech,

Well, the Adata class 10 card came. Looks like it didn't make much a startup difference, but it sure did when I was loading files on the card, now I have a backup... Did some tests this morning:

Sandisk 32 GB Class 4 boots in 38 seconds
Adata 32 GB Class 10 boots in 35 seconds

1750 MP3 Files and 93 Folders on the player
3757 MP3 Files and 178 Folders on the micro sdhc

Winamp/Mp3tag tells me I have no artwork, and the ID3v1 and ID2v2.3 only have the track, title, artist and album. Same file structure as the D2+ and it boots in 15 seconds. Do I need to use a program like Mp3tag to remove one of tag versions, not sure exactly how to do that?

AshenTech · 07-07-2012, 11:23

the advanced settings/options, you have to check/uncheck the right boxes, Im at the office currently So i cant tell you what boxes, do some testing yourself and see what you come up with if you can.

I posted what version of id3v2.3 to use in the tips thread I made the other day.

cold boot in 35sec isnt bad really, better then many players I have used, not as good as some but the ones that boot faster force MTP transfer mode and use MTP to update their database rather then a per boot scan of the whole player.

I have close to 6k files on my card alone...lol

glad it helped at least a bit for you, the load time when sticking files on the card sure helps tho dosnt it.....at least your not stuck starting the copy and going to do something else for an hour or so

AshenTech,

Ok, I got all the v1 tags removed. no difference in startup time. But not a big surprise, since they are already really clean.

I think you hit the nail on the top of the head with this comment "the ones that boot faster force MTP transfer mode and use MTP to update their database rather then a per boot scan of the whole player." (or microsdhc) card. The D2/D2+ boots fast because it doesn't have to scan the sdhc card as the C2 does. It just assumes there are no changes if you haven't removed the card since the last time you used the player, much more smarter idea. Not complaining about either player, just pointing out differences. For what its worth, I like both.
