Re: fat32 question

[Tomoaki AOKI]

According to "Real Hardware Gotchas" section in [1], FAT32 fs creation
of FreeBSD seems to have some problems.

Try formatting by the hardware you're going to transfer files from
FreeBSD, if available. Once formatted by other OS, read/write/delete
files in FAT32 formatted media would be OK with FreeBSD.

If not, and if the file you want to transfer is small enough, partition
the media and use FAT16. (The safest maximum is 32MB, but maybe under
2GB would be OK.)

FreeBSD has no problem when the file system is directly on the device.
Other operating system have problems with it as they expect partitions.

fdisk is a bit outdated. Use gpart for partitioning.

First, thanks all for replies!
After a bit of puzzling, I found that the problem was every Transcend
usb stick I have. They are all fine for mundane tasks and newfs_msdos
makes it able to work on freebsd. My music player was picky and has
something to say against. When I inserted old and forgoten Verbatim
drive, without making f32, it presented itself and files were ready
to play. Unbelievable.
Yep, I did fdisk step after I posted the question. No go on Transcend.
Might be hardware incompatibility or else. Btw, I always do just newfs
on back up usb disks and never had any problem, so far, on freebsd.
Once again, thank you for help.

Zoran, re Brandon's "won't understand it any more."
Dont despair & discard stick, you can rebuild the MBR: man fdisk
from memory start with fdisk -i -B /dev/da0 

sometimes I then remove & reinsert or even reboot, to make certain
the OS has the new numbers.  I don't recall I've needed to reduce
from FAT32 to FAT16.

Ive not read the uefi page as happily no boxes are uefi here,
but I've often created FAT32 partitions, my notes at
http://www.berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/jhs/etc/devd/berklix.conf

The advice about letting the other native MS FAT device format if it will,
is quickest solution though.

PS Max size of FAT32 = 2TB

This was probably a mistake; USB sticks are partitioned, and you wiped out
the partition table by using da0 instead of e.g. da0s1. Most other systems
--- and automount utilities even for FreeBSD --- won't understand it any
more.

Re: fat32 question

[Bruce Burden]

When I mount a FAT32 fs, it is /dev/daXs1, where X is 0, 1, etc.

I would not expect to see /dev/da0.

>From my fstab file:

/dev/da0s1  /usb_flash  msdosfs rw,noauto   0   0
/dev/da1s1  /usb_flash2 msdosfs rw,noauto   0   0

FWIW, this is 10.0 STABLE.
