I was just commenting on your statement "Rockbox supports only up to 128 GiB" which is very absolutely untrue. As I said, clearly, the only limitation is the hardware, so I don't understand the point of your following comments. You proceeded to repeat "Yeah, but what if the hardware won't support it" which is something I'd already covered.
As it stands, even if you can't access more of the disk from the PC it's still quite possible to use it within Rockbox, as Rockbox can be compiled to see multiple partitions and thus you can copy data to it in two phases (copy it over, move it to the other partition, then copy the remainder over).
See

for more details.

im useing a 16GB card (at this time for intermediate use...need to get the 32 put in) and im experimenting with the possibility of putting SD cards in the pod at the same time (one CF card adapter that has one or two SD/MSD slots) to get more expandability...

Pretec 233x 32GB into a iHP-140 (svc 19572 w/ RTC,) had some initial partition corruption problems, fixed after disabling Database Auto Update.
Something to watch out for: the Pretec case is metallic.

Just installed a 4GB Hitachi microdrive (recycled from iPod mini) and a noname CF2IDE44 adapter in my Jukebox-Studio 20 - rockbox-flashed. Works like a charme without any sw modifications ...

Directory corruption resurfaced after iHP-140 shutdown due to low battery.
Both "Directory Caching" and "Database Auto Update" were disabled.
Updated to 19751, will run the battery flat again to see if this happens again...
--- 2hrs (format and copying back the tracks) and 23hrs (playback) later ---
A message was displayed, but only managed to read the word "EMPTY" before it shut down.
After 1min on charge, the player switched on and resumed from previous track. I've now stopped the player and am running a disk scan to see if .rockbox is corrupted.
I wonder if the corruption to .rockbox directory last time was due to "battery low power off" while the player was updating the random playlist position on the CF card.
--- Check Disk completed without any error ---
Though it's good news, I'm not comfortable with any message that says "... EMPTY...". I think I'll make sure I set sleep mode on in the future.

The message is something like "Battery Empty. Shutdown Now" I can't remember exactly, and I'm not at home to look. What is uncomfortable about that? The battery is low and so Rockbox shuts down.

I'm hoping it is indeed that message, but it disappeared too quickly for me to read. Previously, with HD, it stayed on a fraction longer than it does now with CF installed.
I had a quick look in the codes, and did find the line "Battery empty! RECHARGE!". However, I was fairly sure I saw the word "EMPTY" in CAPS instead.
I was uncomfortable because out of 4 times I've let the battery run down, only once did it power back on OK after recharging. Other times it was:
- ./rockbox became empty
- the CF became empty
- ATA error, the partition became corrupted
I'm hoping none of these is due to the CF being a Pretec.
--- Battery finally went flat,
/.rockbox is again corrupted.
I'm guessing that whilst rockbox tried to save its current state it was not able to complete the write before it shut down.
I hope by using multiple volumes will save me from having to copy over 29GB every time. Hopefully any future corruptions will limit to the partition where .rockbox exclusively resides in.
Is there a way to increase the battery threshold so the player will shutdown a little earlier than at "critical" state?

So I finally did it - after being a lurker and running Rockbox for two years on dual boot i bit the bullet.
So now from a stock H120 that I've had for a good 4 years Ive done the following mods:
1) Bigger battery
2) CF Card Mod
3) Fully rockboxed (RAM/ROM)
Now the problem - following the CF mod my player now randomly freezes when navigating through menus or occasionally when loading or creating bookmarks
I will upgrade to the latest version of Rockbox, anything else I can do?
Lft
EDIT: it happened again today and I got the message: Error Accessing Playlist Control File

Whenever my player "stutters" it is generally a sign of corrupted file system. You may want to run a chkdsk/scandisk...
BTW, I've just noticed that quite often after the the player is turned on with hold switch set and subsequently shutdown (by default,) I get file corruption on the CF.
I'm glad I've split the CF into 2 partitions, so far the 2nd partition of 29GB of music has survived from file system corruption. The damage has been limited to the 1st partition which is where .rockbox lives.

I installed a 4GB ADATA compact flash card into my ipod mini when the original hard drive broke. It only lasted 2 months. My ipod no longer shows up in itunes or as a usb drive. I've ran RockBox on it for the past week and it would freeze sometimes when selecting a new song with Dynamic Playlist turned on. When I turned it off I had no problems running Rockbox. I think it was just a bad card because I was getting "Cannot Sync Ipod" errors in Itunes before installing rockbox.
I wanted to upgrade the card to either a 16GB Transcend Card or 16GB Kingston Card. Do these two work with RockBox?

My results with an F10 Gigabeat and an A-Data 16GB CF card have not been good. After a few hours of use it crashes with a corrupt filesystem, the boot loader and or kernel report a 'file not found' error. Reformating the card and reloading EVERYTHING (or sometimes just the .rockbox directory) being the only cure. I've read on other mp3 player forums of others having the same problem with CF conversion on the Gigabeat. However, others report success (but NOT with the A-Data CF cards). Maybe the AData isn't fast enough (it's only 40x, 133X cards seem to work?) Also there is a better CF-50pin IDE adapter that is built into a metal case the size of a 5mm thick 1.8" hard disk (available on ebay for $11-$50) that seems to work better.
If you have long term success (say it's been working for over a few months with daily use) with a CF converted Gigabeat F, please post what you did (which CF card, which adapter, any rockbox or bootloader patches, etc). Put it on the rockbox CF wiki too (so far there are only TWO entries there for the Gigabeat and mine was posted before my file system corruption started showing up).
I will probably get the better adapter (it won't bounce around inside the player!) and one of the OEM Toshiba 133X CF cards on ebay (reported to work with ipods) and try again.
UPDATE ----------------------------------------------------------------------------------------------
I got a new 32GB CF card off ebay on friday. It's a generic OEM card made with Samsung parts. It was reported that both the 16 and 32gb flavors of these worked with iPods, so I took a chance.
Still using the el-cheapo 50pin to CF adapter, but I cut down the jumper pins and soldered a wire on the back of the board (the case jumper was pushing against the back of the player).
This time I didn't have the usual problems of the USB transfers stalling out it I tried to drag and drop whole directories (or *GASP* directories OF directories) at a time. Also no failures to create directories either. I got it loaded with about 4.5gb of mp3 and ogg files now and so far (knock on wood) hasn't yet crapped out with file corruption (Jinx Jinx).
It DOES seem to take longer to shut down than with the HD though (why?).
What worries me is that rockbox might be constantly updating files tracking playlists and ratings which shorten the life of a CF chip (limited write cycles). IMHO, when using CF rockbox should not write to ANY files on the disk, and keep everything in ram UNTIL the unit is shut down. Then during the shutdown process save as little as possible to 'disk'. Config files are kept on the 'disk' but are only written when the user actually changes something.
The other little complaint is that the 32GB card 'only' seems to hold 30GB. I know disks are rated in DECIMAL GB and software reports HEXADECIMAL units. But I thought flash memory was rated in HEXADECIMAL units, so why the reduction in storage size?
?
PS I wanted to change the CF wiki, I have a password and was granted permission to write to it awhile ago, now it won't let me in (takes my password, but the edit link returns a blank screen) do I need to ask for write permission for EVERY update?

I've had a 16gb Kingston Pro Elite card in my ipod mini second generation for about a month and it seems to be working properly.
Since compact flash cards are thinner than the original ipod harddrives I used some double sided tape to attach a strip of rubber from a cut rubber band to go in between the card and the case. I could hear and feel the previous adata card I had used rattling around.
