    Ok... I've been holding off posting this because I was sure I knew what I was doing. Apparently, I'm not as smart as I thought I was...

    Here's the problem: I have TTN6 running on my 650. When I first got TT, all I had was a 256mb SD card and I was limited to using a small regional map with it. So I bought a PNY 2gb card for 29.99. Reinstalled TT with the full US map.

    Life was good until one day it was very sluggish and wouldn't calculate a trip. I figured something got corrupted so I reformatted the card and tried again. Same thing: after a few days TT started acting strange with the sluggishness and errors.

    No problem... I figured cheap SD card so I bought a standard SanDisk 2gb. Format and install TT. Use it for a few days. Guess what? Sluggishness, lock ups etc.

    I also began to notice that the card could no longer be read in my card reader although the Resco Explorer didn't seem to have any trouble accessing it on the Treo. I even installed CardReader from Mobile Stream and it works fine so I really don't think it's the SD cards.

    I happened to see a SanDisk 2gb Ultra II for 39.99 and grabbed it thinking it was a better than average card. Yeah right. Same problems as the other 2gb cards: sluggish performance, lockups, etc.

    The USA map was deleted and replaced by the same regional map I was using initially. I figured I'd try the same setup on both my 256mb and 2gb cards for comparison. No dicew... the 2gb still acts up.

    So I go back to my 256mb card. After almost 2 weeks, performance has been flawless. Zippy response from TT, no lockups, etc.

    What's the deal? Is there a reason my 650 doesn't like these 2gb cards? Is it an issue with TTN6 and cluster sizes? Yes, I've tried contacting TT support but get nothing helpful back except to reformat and reinstall. All the other apps I have on the card(s) work fine. It seems to be something specific to TT but I can't nail it down.

    Has anyone else had anything similar with TTN6 on a 2gb card in a 650?

    Hi Mark!

    SWAG thought: What directory is TTN6 in on the 256mb card? Has it been the same for your 2GB attempts?

    Another thought . . . a test for the 2GB cards . . . monitor the card hourly or each day. . . . is it's "free space" changing?. . . . is TTN6 handling the greater space differently and maybe leaving temp files out there that eventually clog up the works? Does TTN6 use a "memory cache" on the card? Is there a clear cache on exit toggle within TTN6?

    Both (all) cards have the same exact directory structure and contain the same files. As a matter of fact, the 256mb and 2gb cards currently in use are restored from the same backup.


    is it's "free space" changing?
    Not that I can tell.

    Not that I've seen.


    Does TTN6 use a "memory cache" on the card? Is there a clear cache on exit toggle within TTN6?
    I don't think there's any cache, and there's no clear cache command. I've ejected that card with TT running to see if there's any temp files but have never seen any.

    As I said, this behaviour only happens on the 2mb cards. I don't have any card between 256mb and 2gb so I can't test any further, but I think it has to do with the cluster size somehow. It's really the only thing different between the 2 card sizes.

    When using the 2gb card, if I let TT run, the sluggishness starts within minutes. It's almost as if the app/Treo are getting bogged down reading off the card. This is really noticeable when TT calculates a trip. Using the 256mb card, a trip of 25 miles calculates in about a second or two. The SAME trip from the same starting point on the 2gb card takes as long as 10-15 seconds and many times just hangs for over a minute.

    Unless it's caching all the "wasted" space in the card clusters, I don't think it's the Treo (dbCache, etc) since the 256 card never exhibits the slowdown, but who knows?

    I was hoping someone with the same setup (TTN6, 650, 2gb card) could confirm or deny this behaviour. I think I'll pick up a 1gb card and see how it works in this configuration.

    Mark, have you had any progress on this?

    Not really.

    I'm trying somes tips I read elsewhere but so far nothing and the sluggishness is still there on the 2gb card.

    You might reformat it given some of the threads on the subject with a different block size. I think the default is 16k, might try 32k..

    I've found my 2GB card slower than my 512M as well.

    I have TT6 on a 650 using a 4GB Sandisk. Recently upgraded from a 1GB Toshiba. Eventhough I have space for it, I do not use the full US map because it is significantly slower than with regional maps. In my situation, the 4GB seems to be slightly faster than the 1GB using the same map. I have not noticed a slowdown or sluggishness so I'm not going to be much help. Can't remember TT5 or TT6 ever hanging during a calculation but resets sometimes occur. I do notice that TT6 goes through a writing directions step after the route calculations but I assume that is using the DBcache rather than the SD. TT has always caused some resets (due to the heavy DBcache use) but this does not seem to be related to the size of the SD card. I am using the 32k cluster size for my 4GB card since that's what it came with. My install seems to calculate a 25mile route in about 5 sec. I'll let you know if I experience any of the problems you are having. I only just upgraded to TT6 about a month ago so I'm still getting used to the minor changes from TT5.

    T650, TT5, and 2g card. I used to see recalc slowdowns when dbcache was low (or at least that's the only thing I could attribute it to). Never had problems when upgrading card (256 > 512 > 1g > 2g). Seems apparantly dynamic, in that you say it works fine at first on the 2g but then slows down after some time. May be worth a shot keeping a closer eye on both free and largest free dbcache. You didn't mention, but figure you probably have done resets and retries after the problem occurs to see if it goes away (or used other methods to free some dbcache).

    Once the slowdown starts, nothing seems to help: exit and restart TT, reset, etc. The only way to get the performance back is to reformat the card and restore/reinstall TT.

    Once the slowdown occurs, can you exit TT, swap to the smaller card, restart TT, and find that the slowdown is gone (without resets in between)?

    Yes, I have confirmed this.

    The 256mb card runs fine each and every time. The 2gb card(s) run fine for the first hour or so and then go into slow motion. Once it slows, nothing seems to get it back to normal besides reformat/reinstall. It's almost as of the card is somehow getting corrupted during a write.

    Another thing I've noticed is that the voices start to "machine gun" when things act up; instead of hearing "turn left" I get "t-t-t-t-t-t-t-t-t-t-turn left".

    Puzzling AND annoying...

    It's kind of drastic but you might try going to a custom rom with FAT32. 2GB is the upper limit of the original FATFS so it may be something related to the card access process (probably read rather than write). Voices and maps are both stored on the card. My 4GB is a new standard SDHC so I have both the FAT32 and the other file updates needed for that in my custom rom. So far, I've not experienced any slugishness or hangs.

    Drastic indeed. I was considering FAT32 but my Treo's been near flawless since day one so I'm not eager to mess with it yet.

    Another odd thing is I wanted to try a smaller cluster size to see if it made any difference, but I can't seem to format the 2gb cards in Windows using anything but the default settings (32k).

    Have you tried using the format command at the dos prompt?
    If you enter help format, it will give you the syntax for various cluster sizes.
    You also have to watch out for making the size too small because there is a limit to the maximum number of cluster you can have for FAT or FAT32.

    Yes I've tried, but Windows will only allow 32k on a 2gb card (FAT).

    I would imagine, since the card is new, that the files on there aren't fragmented? I think flash cards are susceptable to fragging.

    As an update: One of the tips I was given was to turn off ALL POI's. Well, I did and have had TT running all day here at home. So far, no slowdown. Of course, TT isn't really doing anything, although I did try calculating several different routes and used as many features and preference changes as I could. I'll throw it in the truck tomorrow and see what happens in real use.

    Well, I've been running all day with POI's disabled and haven't had any problems. Response time has been what I expect it to be with no lockups either.

    It occurred to me that in addition to the standard POI database, I downloaded and installed a special Dunkin Donuts POI file. I'm wondering if it's that particular file that causes the problem? I'm going to re-enable some of the standard POI's and see what happens.
