Memory Card

Note that it is made by Samsung.

This is a 1 Gig chip, the only physical difference from a 512 is the lettering on the chip.


No components are user servicable except the flash memory card

Thanks to "turbodog" on the anythingbutipod forum for information on the chips.

The DM 621 battery soldered on the m200 circuit board is to keep the Real Time Clock (RTC) alive during power off.  The clock is only used to check expiration of timed items such as borrowed books from libraries, etc.  Since the m200 series is an "economy" model, SanDisk chose not to include a clock in the display.

The chipset also supports a recovery button, but again, SanDisk left that off.  Since the m200 is no longer manufactured, there's no hope of having it added.

Awesome addition. Thanks go to the original poster.

Re: Adding a bigger memory chip to the m200

I did just that.  I bought a m230 (locked up) and a m240 (broken display) from Ebay for $6.99 shipping included. Took the memory chip from the m240 and plugged it into the m230.  The m230 has a version 2 board and the m240 had a version 1.  The m230 is now a m240 version 1.  The version (firmware) followed the memory chip. Can't guarantee this will work for everyone, but it worked for me. 

Incidentally, the sound has gone out on the second circuit board, so I now have two non-working units. If you buy a "locked-up" unit, chances are very good it is the memory card.  The m230 would not power on and was not recognized by the PC, but it works great with the m240 memory card (except for no sound).

Do you know if the "8. DM 621 Battery" is replaceable?

I have a M200 series and it is giving me the "Sync Notice" until I reload the new firmware.  I just noticed the other day that the battery was going low, and when I changed it I started getting the "Sync Notice" again.  I think that the internal battery might be dead and causing the error. 

Also if the battery is replaceable, are there any tricks or special tools needed to take the case off? 

Thanks in advance for the help!

I doubt you can find a replacement battery.  I have tried several times and failed. It is a simple button lithium battery as in watches, but it must be rechargeable.

To open the cover, you may be able to just pull it apart, if not, insert a flat blade in the seam around the edge and pry it.  You may scratch the case doing this.

I doubt you need a new battery.  It should recharge from the AAA battery.  Don't let your battery get below 1/2 on the display.

A search on Google for "m200 sync notice", "m230 sync notice" etc for m240 & m250 turns up lots of hits concerning Rapsody and lots of devices being fixed by formatting. 

I had the error once myself when I first got the m250 but don't remember what I did to fix it. I do know that formatting (both MTP and MSC) cures lots of ills.

Great information and especially at those links, and thanks again. After reading your own page on the m200 I realize more than ever how necessary it is to be careful with these units. Don't just stretch and push them to the limit unless you don't mind dealing with having a piece of junk on your hands. I'm going to try to give the problem areas a wide berth, such as letting the battery get too low (and I do use NiMH, good ones, though from now on!!) and not filling the capacity (i.e. MB's) anywhere very near the 2 GB of the m250.

I'll drop a little piece of trivia here: I didn't have the advertized Stopwatch function until I turned on Smartmenus. Once I did that, the Stopwatch function was there, even after turning off Smartmenus. This is with the latest 4.x firmware.
