If you want to format your device, the best recommendation is to
place it into MSC mode. This is the Sansa's mass storage mode and it
allows the device to be treated as a drive. Go to the settings menu and
find USB Mode. There are two choices, MSC and MTP. Choose MSC. MTP
is for music transfer using a media player software like Windows Media
Player. If you don't have a way to set MSC mode with a menu on the
device, engage the 'hold' switch, and while holding down the left
or right button (others report also using the center button), plug the
device into the USB connector. Make sure the USB is already plugged
into the computer. You shouldn't need to do this with a standard e250;
the menu should work.
After you have connected the
device in MSC mode, right click My Computer and choose Manage from the
menu. Find Disk Management and select it. The disks should be
numbered, starting with 0 for the C: drive. You should see a drive that
says SANSA E250, or something similar. Write down the type of file
system if it is shown. My e260 says FAT32. I believe that the 2MB
e250s are FAT, but check to be sure. There will be two partitions on
the disk. The larger of the two is for your music files. The smaller
is for when the device goes into "hibernation" - it's so you'll be back
to the exact same song when it powers back on. Right click the larger
partition and choose Format from the menu. You will see the format
dialog. Set the volume label to SANSA E250 (I believe that's your
device type), set the file system to what you wrote down earlier (do NOT choose NTFS!) and
leave the Allocation unit size at "Default." Do not check either of
the two check boxes. Click on OK. Keep an eye on the partition in Disk
Management and you will see the percent complete.
it's done, look in the System Tray (by the date and time). You should
see an icon for safely removing hardware. Double-click it to bring up
the safely remove hardware dialog. Click on the USB drive representing
your Sansa device and click Stop. Another dialog will come up and
you'll have to do this again. Close the dialog when the device has
stopped. The device will restart and initialize the music database.
You're done! Now change to MTP mode and sync the device.
Whenever you are in MSC mode, ALWAYS
stop the device as I described in the paragraph above. That way you
won't corrupt the drive. Hopefully. I haven't yet. My e260 is a gem!
