I Can't Do A Nand Backup
« on: February 20, 2007, 05:52:08 pm »
Hello,
I'm trying a  NAND Backup in a C1000 (Akita) . I reach NAND Services menu and I select a NAND Backup in a SD Card.

Then, this message appears:




File: SYSTC100-DBK

Can’t ger free size.

The card has around free 400Mb (of 512 MB) and is unlocked.

I repeat the action in a 4GB CF microdrive, same message.


I Format SD card in Akit whith makefs.ext2, same message.


I try in NAND services SD Test Option y I obtain this message:





SD Card Write&Read Test

1 bit data transfers

No free sector [-1]



SD Card Write&Read Test

4 bit data transfers

No free sector [-1]



Other Info: ROM installed is pdaXrom


I'm lost, i don't knwo what to do... Can someone help me?

First thing to check is if your SD card is formatted as FAT16 (or FAT), not FAT32.
You will get the "Can’t get free size" message with a FAT32 formatted card.
I noticed your SD card is 512MB, so it cannot be a FAT32 card, try a FAT formatted CF card, or try reformatting your SD card, there may be a problem with that particular card.
Also, if you are trying to make a backup to a 4GB micrdrive, it's probably formatted as FAT 32.

The Zaurus backup backup/restore function in the NAND menu doesn't like FAT32, it only is functional with FAT formatted cards, (I haven't used a drive in the NAND menu, so I have no info on using a drive in this situation)

I'm pretty sure that I've successfully done NAND backups to a 512MB card, but I don't recall if it was FAT16 or FAT32.

In any case, I'm pretty certain that you cannot backup to an ext2 formatted card.  As Jon_J stated, you must format the card to FAT in order to backup to the card.

I also thought I had a problem backup up to a large (probably 4GB) CF card, but I'm not certain of this.  It may have been user error.

Can you format to FAT16 under Linux?

I know I have seen how to do this, but the methods I've tried still make is show up as "Linux" under fdisk -l, not FAT16.

Sorry for the dumb question, but it's been nagging at me.

Change the type under fdisk...

at the main menu, hit "T", then the partition #, then I believe "L" to list the codes...

seems that most problems people have with flash memory cards are either partition errors or, especially when flashing OS, fat32 and not 16!

I'm surprised that Sharp didn't update their emergency OS to cope with fat32, it would save a lot of headaches.

Or ext2, as the Z runs Linux. It would make sense to support a Linux filesystem.

well, I suppose so.. but I've never seen an off-the-shelf memory card that came with ext2 formatting, they're all fat16 'cept for the >=4GB SD and SDHC cards.

I'm not surprised by the lack of ext2 support, as Sharp apparently did not intend for people to be flashing a new OS.  I get the impression that they may actually be unaware of how their devices are being used by communities such as this.

In fact, is the diagnostic menu even a supported feature that's intended to be used by the end user?  Sharp probably did not intend for end users to be doing anything beyond using the factory configuration and possibly installing a couple additional apps.  Palm recognized the Palm developer community, whereas Sharp seems to have mostly ignored it.

how are the Japanese zaurus communities reacting to the news of the end of the Z?
