    I have a non-functional 256MB SD card which suddenly stopped working in the Treo 600 GSM hardware revision B.

    It was working long enough for me to fully load it with MP3s, and then show it off to friends for a day, but then suddenly the Treo stopped recognising the card.

    Luckily, I bought the Treo and the card from the same place, and the guy there will either replace the 256MB card or replace it with two 128MB cards if I like (all Sandisk brand, unfortunately).

    Firstly, has anyone else experienced a Treo corrupting a card ? I know of the Tungsten 3 problem - I hope the Treo is not the same.

    I also know that Sandisk is not a highly regarded brand for PDA SD cards, but it was a "throw-in" deal at purchase of the Treo, so I didn't have a choice.

    Secondly, does anyone know if the T3 problem only occurs on writes (e.g. if I load the card elsewhere, and then write-protect it in the Treo will I be alright) ?

    Thirdly, does anyone know if the problem is limited to 256MB and above cards ?

    I just expereinced the exact same problem today with a San Disk 512 card.
    Did the two smaller cards work in your phone as they should. I'm wondering if I have a faulty card or faulty phone?

    When I iniatally insert the card it the phone reads the card info correctly. When I try to access it through an app it does not show up. Upon re-checking the card info the device ID and manufacturer show up as "unkown"

    I got a replacement 256MB card, so I never tested 128MB cards. I've just tested it with a backup with BackupBuddyVFS and it had no problems. But the other card only failed on the second day of heavy use on a full card. So I'm yet to really stress this one.

    My symptom was that the Treo did not even recognise the card when it was inserted. I would expect that a reformat in the Treo might fix your card.

    I have the 256mb Sandisc and it works great. Every once in a while I have to pop it out and then back in for it to recognize it. At most once a week.

    rhitby, I assume you tried reformatting the card and it still didn't work?

    Same here - so far mine is working just fine. When I first got the card, it did recognize it in the Treo, but I formatted it anyway.

    I couldn't reformat it in the Treo, cause the Treo didn't even recognise the card. I didn't have an external SD reader to reformat it either. I just took it back to the shop to get a replacement.

    Mine was fine until I used it in a card reader. Then the Treo said it couldn't launch what it needed to to see the card. It knows it's there, but can't access anything on it.

    I've heard so many problems with Sandisk SD cards. Not sure it is Sandisk or Treo or both that caused your problem, but I'd avoid Sandisk brands at all possible. It seems like a time bomb that can go bad at any time.

    ... i would advise not taking your SD out and putting it into a USB memory reader or anything like that ... also don't swap the SD around too much... I know that's what they're meant to do, but I corrupted mine a lot.

    Got replacements, but still going without a card sucks. I eventually narrowed my problem down to a faulty SD memory reader, bought a new one and always eject the device from my laptop before removing the card.

    These things I've noticed are sensitive. A lot of people on the Palms boards when I had my Tungsten complained and swore by Lexar.

    I stick with SD for cost and their tech support isn't half bad.

    I just became a victim of the "unknown format" problem after i tried using the Kanguru MicroDrive+ USB card reader with my 512MB card. I even put the SanDisk card in the Tungsten C with the same results. I bought the SD Card from Sears but don't think I purchased the replacement warranty. I wil put a call into Kanguru's Technical Support area. Now, the USB card reader keeps prompting me to "insert card into drive F:" I'm certain the the reader blew up my card....

    After my SD Card got fried, I Googled and found PC Inspector site which specializes in media data recovery. They have background information posted on their ABOUT US indicates that they were "entrusted with the recovery of data from storage systems that were destroyed in the attack on the World Trade Center of 11 September 2001." BONUS: Software is freeware and advertises that it is freely distributable.

    So far PC Recovery Smart Recovery has detected my fried SD card as removable data with 478MB free space in ready state.

    I've used both Sandisk 128 and 512MB SD cards with no problems. I had the 128MB card loaded up with MP3's and one or two apps, then got the 512MB card. It's probably about 60% full, MP3's mostly, but more apps. I've used both cards in the Sandisk 8-in-1 USB reader and my Treo, as well as a Sandisk PCMCIA adapter, and have never had problems with either card in any location. I initially had an issue with the USB device and my virus software causing a conflict, but a simple setting in the virus software fixed that.

    I loaded my sandisk 256 with MP3 files. This was fine until I went to change some files using the Dazzle card reader and the PC revealed that all file names and extensions were gobblde gook. I reformated card in the card reader and re-loaded some MP3s... worked in Treo 600. Put the card back into the Dazzle, and lo and behold, corrupt files again.
    The dazzle would not even reformat the card this time.
    Formatted the card in the T600, this time Dazzle loaded files.
    Back to T 600 and playing fine with Ptunes.
    Card back to PC/Dazzle, and again all files corrupt...
    Would not format using Dazzle and Windows XP.
    Back to T600, format, and back to Dazzle, agian able to laod files...
    what the Feck is going on! obviously the card is not damaged... the T600 works, Dazzle works, but all three together and it is disaster.
    Now, it you can follow all that, you are amazing, if you can fix it, you are a god!

    I too have the SanDisk 256mb card, a Dazzle 8-in-1 Card Reader and Windows XP. Your experiences are hauntingly familiar to me! Based on what I've read, I do think the SanDisk cards are more easily corrupted than other SD cards.

    I also tried to bypass the Dazzle reader by using Softick's Card Export - software that basically lets the Treo become the card reader - but Card Export crashes my WinXP laptop hard. I'm bummed because Card Export is otherwise great and would have been ideal for me.

    Now I am looking into USB drives that can accept an SD card, and will see how that goes.

    Iíve tried a 128 FujiFIlm card and that couldnít be read from the Treo or from my computer, using a SimpleTech AllInOne reader. From the computer I received ďThe file or directory is corrupt and unreadableĒ. Then upon reseating the card I would be able to see some of the files but their names were jibberish. I tried formatting from the treo which took a long time (or I restarted the Treo, I forget), then formatting from the computer, nothing worked. I returned the card and purchased a 256 SanDisk card and that worked fine for about a week. I had mp3ís (using pTunes), saved pix, and stored SplashPhoto files on it. It was great until earlier today. I played an mp3 then about an hour later tried to play it again and received and err trying to read the card. Now the same thing as the 128 FujiFilm SD card has happened. If I insert it into my Treo is locks up and I have to reset it. If I view it on the computer the files are jibberish and folders are inaccessible.
    Very disappointing / frustrating. Any explanation as to why this happens?...
    Also, Iíve upgraded the system to the Treo600SprintUpdater1.10.exe (which is when my Treo had itís first system lock up and I had to restart, but thatís another story). Oh, the 128 card was used before the upgrade and the 256 was after. Just fyi.
    In a thin section it often exhibits a fluidal structure, marked by the arrangement of microlites in the lines of the flow of the molten mass.

    Re formatted with the T600 this morning and copied mp3's to it from the computer. Look at it thru pTunes & Filez and the dir structure is screwed up... Not what I had originally created when coping the mp3's. eg...
    original: /music/albumNames/filenames
    current /palm/albumNames/jibberishFileNames & /music doesn't have any of the albulmNames but does have /launcher...

    Any comments?

    Thanks

    Sounds like a problem with the Dazzle reader, to me. That's where your files all get scrambled, right?

    I've got a sandisk card, a Lexar card, and a Lexar reader, and have had no problems with any of the cards in the Treo or in the reader.

    Sent it back. Still waiting for a replacement. There are known issues with Sandisk cards, not just on the Treo 600.
