Device memory- Total is only 27GB?!
 
1 Attachment(s)
When I checked out settings - memory - details it says my total memory is only 27GB, not the 32 which it should be. Thats a drop of 5gig thats not in use by system files or anything. Anyone got any explainations? Is yours like this too?

Well that cuts 2gb off the list. What about the other 3?

The Maemo OS take up space . . . this is true with any computer . . .

offtopic is the rootfs 256MiB or MB?

e: checked things just to be sure:

27GiB = ~29GB
2GiB = ~2,2GB
768MiB = ~0,8GB

= 32 GB
seems to explain the phenomenon.

Run "sfdisk -l /dev/mmcblk0" from the terminal.

28,995,223,552 bytes for MyDocs
2,147,483,648 bytes for /home (and /opt, for applications)
805,306,368 bytes for swap

Total = 31,948,013,568 bytes. That's not quite 32,000,000,000 bytes.

Hey! We got shafted by 51,986,432 bytes! Where's my 50 megs gone? Oh partitioning boundary rounding probably.
