Is the SD only with T3's???

[n0m0n]

I ran across this on another forum and thought it might be of interest to T3 SD owners.
I have also copied a response that re-directs the issue to SanDisk.

It's true, my T2 fried my new Sandisk 128Mb SD card!

I've been using the SD card without any problem for about a week until I downloaded some MP3 songs and tried using the RealOne player for Palm from the SD card, the Palm suddenly freezes.
After a reset, the card is totally unrecognisable, not even cannot even be formatted from a SD reader on a pc. Looks like my SD card is gone.

I've emailed to Palm 2 days back, so far have not hear any response.

Response:

This may not be the Palm's fault. I had a Sandisk 128mb SD card go bad in my m130 after 5 monthes with no problems. I got SanDisk to replace the card and have been using the replacement in my Zire 71 for 3 months with no problems. Many people have had problems with SanDisk SD Cards going bad. The T3 issue is it fries cards other than just SanDisk.


Again I ran across in another Forum, so I hope this is ok to post here.

Just as an FYI, a buddie of mine bought the Zaurus PDA when it came out and that thing fried every SanDisk card that was put in it. Sharp had to issue some sort of patch to fix this, and I think most cards were restored to working order. This has to do with SanDisk, from what I hear

Now I'm confuse :confused: Sandisk SD card problem or device problem?

From what I read, there are some PocketPC machines having issues too. I think Dell Axim being the biggest one. It also doesn't appear to be just SanDisk cards. From what I was reading somewhere on the net it appears to be a SD controller problem that may have been used on PocketPC/Palm PDAs.

I am sure it a device problem. It's just the Sandisks can't handle it as well as the others.

It's partly Palm and SANDISK

Good post.
I was looking for a comparison like this one
Thanks.

A quick rundown for some:

There is a standard for making SD cards. This standard includes a set of commands that the SD card should be able to accept.

SanDisk does not make controllers to this standard.

They do however make their cards significantly faster (number made) and cheaper (wholesale) than most others. This means that other manufacturers have a habit of rebranding them. Due to the difference in their controller chip some SD devices are not able to handle them correctly.

Normally this isnt a problem in devices such as cameras and MP3 players where it is a simple slow read write.

The problem occurs when devices get smart. The device tries to call commands to access the filesystem. These commands are different on a SanDisk SD than everybody else's. This causes failures eventually and at the end of it the controller will burn out.

In other words - either SanDisk makes thier controllers to the specification or every SD device manufacturer out there makes their device controllers able to understand SanDisk's unique command set.

Just get Lexar cards. They are a good card and as long as they aren't SanDisk underneath - your fine.

[n0m0n]

Well As long as the Lexar card was not manufactured by SanDisk and labeled as Lexar .
There are only a 2 or 3 companies that manufacture cards.
They are then labeled for which ever company purchases them and repackages then for sale .
When you get your card go to card info and check who the manufacture was.

Interesting how one can find that not just the T3 fries cards! I keep repeating that I fried cards on my 505 and T, but everyone still believes that only the T3 does it. It might not even do it more than others!

Not sure what you are saying is totally accurate.
I don't believe that people are saying that ONLY T3 units are frying cards.
I think that since the T3 is the newest, and best, and that a whole lot of people who ran out to buy the T3 when it first came out, it is now the loudest.
So you will hear more people, see more threads, it gets more attention, to the SD problem then with a m5xx series.
Remember the electro static issues with the m5xx cradles???
Also I know that it was a few months before I purchased a SD for my m5xx unit when I first bought it...
Now I purchased a 128 MG right away with my T3.
So I would have noticed the problem, and would have been a bit louder, then if I waited months.
The price tag is fresher in my mind within the first month, so I don't want any problems.
Now I have not had any SD issues so I will sit await for Palm to address this.
I personally hope they don't take to to long for that would be abusive in my opinion.

[rawbear]

Right to the point and I agree with you. I was one of the early adopters for the 505 and bought a couple of 64 meg SD sandisks right away when it came out. They were actually quite hard to find!

What I'm saying is that there was maybe as many issues with the 505/SD as there are T3/SD. Most people didn't have SD cards then. Who knows about the T? Suddenly, everybody wakes up! Sure, it touches more people, but it mighr have been the same issue all along, for two years!

[n0m0n]

Well It believe that you can make a possible connection on one issue.
Palm units have always been slow to support large SD cards...
At first the 16 MB cards worked but anything higher had issues.
Seems that you can go up to 128 MB now.
Possibly same old story, not sure though, but history does seem to repeat itself with Palm.
