Sansa Fuze memory

(1/3) > >>

schachwhiz:
I have a 4GB Sansa Fuze. I recently put Rockbox on it, and I love it. But I seem to be missing some memory for some reason. I have 41 albums on it, which on my Linux computer, is supposed to be 1.6GB. However, when I look at the free space using Linux, it says I have 2.4GB used, and 1.4GB free, with a total capacity of 3.8GB. When I use "Disk Usage Analyzer", it say I have 1.8GB used, which is probably accurate, considering that Rockbox probably needs some space to work. On the Sansa Fuze itself, Rockbox says I have "Int: 1.39GB/3.79GB". Any ideas where this memory went?

AlexP:
Nowhere.  Hard drive manufacturers uses powers of 10 so they define a gigabyte as 1,000,000,000 bytes whereas operating systems generally use binary prefixes, so it defines a gigabyte as 1,073,741,824 bytes.  As a result your hard disk is quoted as 4 GB by the manufacturer which is 4,000,000,000 bytes, which the OS reports as 4,000,000,000/1,073,741,824 = 3.73 GB

As a note, to try to avoid confusion the binary version has been defined as gibibytes, GiB so you have 4 GB, but 3.73 GiB :)

See e.g. http://en.wikipedia.org/wiki/Gigabyte#Consumer_confusion

Thank you for replying, but I'm not concern about the "missing" memory of 4 - 3.73 = 0.27GB. I'm wondering how, if I put 1.6GB of music onto the player, I have 2.4GB used. What is taking up 0.8GB of space? Is that all Rockbox?

AlexP:
No, Rockbox takes about 20 MB with fonts and all.

There are a few options.  One is that you have songs still on there that you copied over in MTP mode in the Sansa firmware, that Rockbox doesn't see.  Two is that you have loads of space taken up in a recycle bin.  Three is that the free space reporting is wrong (unlikely, but can happen in Rockbox as Windows doesn't update the FAT properly).

Try removing all folders created by the OF.

I don't believe that there are any files on it from MTP mode. Also, I deleted the ".trash..." folder. If I were to delete the folders from the OF, which ones would I delete? The ##MUSIC## folder?
