    32k wouldn't work for me, but 16k did. Will see if it's any faster. Using run-of-the-mill Sandisk 2GB.

    Update: 16k blocks are NOTICEABLY faster, especially in pTunes and CallRec. 4k was DREADFULLY slow in CallRec, but now it's excellent!

    With my 512mb SD card, I couldn't use mVoice's "best" 86k/sec quality setting without noticible skipping in the resulting .WAV file. Since switching to 32k, the audio comes out crystal clear!

    Well I had to revert to "Default Allocation Size" because the larger chunks wasted so much space. On a 2GB card, I only had 800MB of mp3's and .avi's, but it technically filled the card to its limit because of the wasted file space. What's the solution to that????

    4GB card?

    That's not quite a solution if 40%-60% of the space is going to be wasted?

    Must depend on the types of files you're storing or something. I've got 1.23GB on my 32k-blocked 4GB card, which actually occupies 1.35GB. I'm not sure why I'd see less loss with larger blocks, unless my files happen to be bigger--which being a collection of ROMs, family pictures, Palm apps, and mp3s, I doubt is the case.

    Well I had one 400MB avi file and 500 MB worth of mp3's - but that showed literally over a gig used up on top of the original 900MB.

    FYI, I used this command: format E: /FS:FAT32 /A:16K

    You must have something else going on. At the most you should only "waste" 1 allocation block per file. The missing 1.2GB would correspond to over 37,000 files if each wasted 32K. If you are using 16K then it would be twice that many. Have you checked the card's capacity on your PC?

    Does it report the same amount of wasted space on the PC? Try running

    chkdsk /f CARDDRIVE:
    I'm thinking maybe there are bad blocks on the card, or some that weren't marked "available" when files were moved or deleted. If chkdsk can't fix anything, copy everything to the pc, reformat, and copy back.

    Yes reports same wasted space on PC.

    physical bad blocks or memory errors? Card works fine when formatted at the default, which appears to be 4k.

    ...fine, albeit slow on FAT32. On FAT16 it was normal.

    I have to admit I'm baffled, at this point. Have you tried the 8k median between the default 4 and wasteful 16?
  15. #35  
    Okay, I have results from formatting in Windows (XP, in a cmd prompt) using 8k allocations.

    Then I have results from formatting the card on the Treo 650.

    As you can see, formatting in Windows produces bad sectors. Anyone know why?

    This is Windows formatting:

    I've got a guess for you, Beagle, but it's only a guess. I'm thinking Windows format does some error checking that the Treo's format app doesn't. When the Treo tries to report how much space is available, it runs into the bad sectors it hadn't detected during the format. If you would, do a few more tests:

    First, with the card formatted to 16k, use FileZ to select the card and hit the details button. It'll pop up a screen that tells you how many files are on the card, and how much space they take up. Does that size reflect the correct ~900 megs?

    Does this same missing space issue occur with 8k blocks as well?

    Next use Windows format, format the card with the default 4k chunks. Does it still report nearly a gig lost to bad sectors?

    super, in between my last post and your most recent post I added /q to the syntax (for quickformatting) - appears to have alleviated all of my problems. Not sure why, but with /q there are no bad sectors.

    Also, does anyone know why some people can get 32k and others can't (like me)?

    Quickformat doesn't do any error checking. I'm suspicious that they're still there, undetected.

    Pretty sure it has to do with the card size. You're on a 2gb card if I recall correctly? I bet if you were formatting a 4gb card, you'd be able to use 32k blocks, too.

    Bingo. The following bullet is from MS info on FAT32 limitations

    A volume must contain at least 65,527 clusters to use the FAT32 file system. You cannot increase the cluster size on a volume using the FAT32 file system so that it ends up with less than 65,527 clusters.

    2GB cannot provide more that 62,500 clusters of 32k blocks.
