microSD HC card read problem
 
I'm fairly new to the forum, I did some reading but I'm still having problems, sorry if it's a repost of same issue.

I installed rockbox version r15924-071214 on my e200 firmware 1.00.12A
While in MSC mode I attach USB to my PC then insert Sandisk 4GB micro SD HC card and "Removable Disk K and L" appear in My Computer. The K drive is my sansa and all the folders are there and I'm able to access them. The other drive L I'm assuming is SD card but I cannot seem to drag and drop files to it. If I double click to open it says "please insert a disk into drive L"

If I connect my sansa to PC with the SD card in it then system refreshes and same thing as above occurs.
Also rockbox reads the card because it says there is 3.87 gb of space on MSD.
I didn't format the card or anything, and if it has to be done I'm not sure how to do it in rockbox.
I've tried different ways of connecting and nothing seems to be working.
Can anyone help?
thanks

It is because OF will not read or see microSDHC cards. You need to use a card reader that can read them.

So I need to transfer the music to my SD card through a card reader, adapter or any other way but not through my sansa via usb?

advcomp2019 09-15-2008 10:11 PM

Yes, you are right there. Whatever you use needs to read SDHC cards.

Well I took my Sandisk 4GB SD HC card to work and used SD adapter, plugged it in to Verbatin 15 in 1 card reader, two drives popped up in My Computer and I can't access either of the drives. I get "Please insert a disk into drive xx"
What is going on here? Could it be the reader, adaper or card?
Any ideas?

It could be that the card reader sees the card, but does not like the adapter or SDHC cards.

Are you sure the card reader is SDHC compatible? If not, it would show the drives (the card slots on the flash drive), but not the card in them. Happened to me. I got a Kingston 9-in-1 reader. Works great.

I think you might be right. The 15 in 1 reader says SD/Mini SD on the slot but I couldn't find Micro SD or SDHC. I assumed that as long as you put MicroSDHC into SD adapter than it should show up since SD is compatible.
Weird.
thanks

SD is not SDHC compatible, so that won't work.

What is the highest size memory card a rockboxed e250 can take?

How to get stuff onto your SDHC card if you dont have an SDHC card reader:

(1) Boot your sansa into the OF
(2) Copy music into the sansa's internal memory
(3) Uplug sansa, reboot into rockbox
(4) Using rockbox's context menu, move the music from internal storage to the SDHC card
(5) Repeat steps 1-4 until the card is full.

Note that it's worth being careful as the card gets nearly full, i'm not entirely sure rockbox detects when the card is full correctly, and it can 'wrap around' and start overwriting existing files.

This USB Test Build Might Help
 
There was a USB Test Build posted a few days ago on the Rockbox site.

Rasher said:
"After r20032, there's a good chance that Rockbox USB will work nicely on PP5022/PP5024 devices."

This includes the Sansa e2xx players. I don't know enough about Rockbox protocols to know if or when this unsupported build will be part of the official release but this seems promising to me.

I installed it over my existing Rockbox installation and it seems to be functioning OK. The first time I reconnected with Rockbox running my Vista SP1 setup gave me the "installing drivers" popup and half a minute later I was able to transfer files to and from the 4 Gb SDHC card installed in my e250. I have been using the card as I would any external drive with no problems.

The one thing I noticed was that like before if a large capacity card in in the player and it is plugged in while turned off it will try to go to the OF and freeze. If Rockbox is up and running when you connect you see a USB symbol and the card is visible and usable as an external drive.

We're looking to have it enabled in official builds within a week. There's a few more tests we'd like to do before we enable it. We're hoping to have the kinks ironed out in time for the 3.2 release so that the stable version will have Rockbox USB support, in which case I'm hoping the bootloader behaviour will be changed so that it doesn't default to the OF when USB is detected.

skip252 02-21-2009 07:26 AM

Thank you for the information and all the work you and all the others have put into the Rockbox project. I will look forward to the 3.2 release as I experiment with the test build. Having a fully functional USB stack is very convenient.
Thanks again.

Oh, this is HUGE. I'll be watching for 3.2. Being able to basically ignore the OF all together is a wonderful thing. :D

sansaguy 02-21-2009 02:23 PM

finally!...Rockbox USB support. That sure is music to my ears. Can't wait. :D

trebo 02-22-2009 04:42 PM

what... oh man thats great news

i use my e260v1model with a 8gb msd card, what i do is copy stuff on internal memory and with rockbox on my 8gb msd card - no news..

@ Daveybaby you are right with my card also, somehow when the card is full or almost i become no msg and its never ending copying files to the card, and i guess i lost some data, no clue what, without msg or sth.my 2 cent.s ;>

Llorean 02-22-2009 06:52 PM

If there are issues with full cards, why has nobody actually filed a bug report?

trebo 02-23-2009 07:51 AM

what i can tell, is that the usb test build from rockbox is working for me and thats a big step for me with my e260v1 without cardreader.

copying files from windows directly to the card, delete, move, edit, no problem, well. i should have visit this forum some days earlier ;)

whats not working for me, is to see the properties from my 8gb msdhc card from sandisk, its failed to gather information, when i am in rockbox, but i had this problem also before, with the internal memory.
