Title: SD 512m cards
Post by: genxweb on January 13, 2004, 09:17:00 pm
Wil the sd 512m cards work n the sl-5500. I see alot of people talking about the 256m ones but no one has mentioned the 512 ones yet.

Also Iam not talking about the sandisk card iam talking about th secure digital card.

Thanks

As far as I know it should work fine.

Sandisk are one of the leading manufacturers of SD cards, although they have a reputation for failure in their 512MB SD products, Lexar are a good brand to buy though.

I have the 512mb SanDisk card, and it works fine in my 5500 (as stated in other threads).  I also just got a 256mb SanDisk card from Costco real cheap... works great.

The people that say stay away from SanDisk are usually referring to a bad batch from Asia, but that was quite a while ago, and I haven\'t seen any posts recently from people with troubles...

How about the 1.0 gig sd cards do they work with the 5500, Is there really a limitation on the size of the mem?

Where can you even buy a 1gb SanDisk SD card...  you can\'t seem to from SanDisk direct or a couple of the online retailers...

Either way... I have a 1gb SanDisk CF card and it works fine... so I doubt there would be an issue with the SD... I think it gets questionable when you reach the ]2gb range... but I\'m not certain about that.

I saw the 1gig sd on ebay not sure if it is real or faked the image did not lock doctored and the seller had a feed back of 400. I did not bid on cause I could not find proof of its existents any where else.

Just checking Thanks

Cards with capacities over 2GB must be formatted FAT32, a newer variant of the FAT file system.

Actually, I\'d recommend ext3 on the Zaurus.

that\'s the funny thing... if you go to sandisk\'s site. .they show the 1gb SD card, but it\'s not available for purchase even on their site... they don\'t even say that the 1gb card \"will be released soon\" or something.

Many high capacity cards are on amazon.

Is ext3 a better choice than  ext2  for an SD card format?

I have a 512 MB Kingston SD card in my Zaurus, and it\'s been working fine.  Sandisk SD cards (of any size) definitely seem problematic; the forum posts I\'ve seen regarding them have been split pretty much 50/50 between \"always worked fine for me\" and \"flaked eventually, no longer usable\", even among the more recent reports.  Given that I haven\'t heard anybody complain about an SD card from any other manufacturer, I\'d strongly recommend buying anything other than a Sandisk; the cost difference is small enough that it isn\'t worth taking a chance on.

The first (Sandisk) 1 GB SD cards were announced at CES earlier this month, and should start becoming available by the end of the month; other brands will follow in the next few months.  For more information, see:

http://www.pcworld.com/news/article/0,aid,...d,114128,00.asp (http://www.pcworld.com/news/article/0,aid,114128,00.asp)

Even people who had no problems with their Sandisk SD cards using FAT frequently report problems when they try to use ext2 instead.  Don\'t specifically recall anybody having this problem with other brands, although I could be mistaken; I\'m pretty sure a number of people are using ext2 on Lexar SD cards without problems, though.

I have a lexar 512MB SD.  It seemed to work on the 700 w/ sukoshi kernel.

Since then, I\'ve only had a hell of a time with it.  I can write to it, but any sustained writes
seem to make it go offline and all subsequent writes fail until I reboot and fsck before mount.

try to install zdebian on it on 760? no way.... untar a file? offline.  under 760 cacko x11 rom --
try to install perl to sd? bewm.... offline.

I may buy a 256 sd just to have another sd, perhaps I\'ll get a card reader and just keep
data on them to be mostly read only (mp3s for travelling, etc)....

(heavy) writing to an SD?  forgetaboutit.

I have the same problem (no sustained writes) with my 512MB SD card (Hagiwara M series SD card).

came accross some interestring info while surfing today.....

Aparently tungsten T3 users are experiencing a tons of related SD card memory corruption...only common factor is Sandisk.

\"We strongly suggest that you do not use your SD card in your Tungsten T3 if it is manufactured by Sandisk.\".....bits \'n bolts

Has anyone used a Ridata 512 (or above) CF card? Just wondering if anyone had any good or bad comments. Thanks.

I\'ve been using a 512 MB Ridata CF card for over a year, been used in a few SL-5500\'s and an SL-C760; works fine, haven\'t had any problems with it.  Have another one in my digital camera, again no problems.

BTW, I just grabbed a 512 MB SanDisk card at Circuit City for $169 - $40 mail in rebate.  It ends up at $129 + tax, which seems to be a pretty good deal, especially since I had a $80 exchange-only item to get rid of.

Yes, the SanDisk card works just fine.

The cards that suffer from this problem are few and far between.

It is unusual for a lexar card to exhibit this problem.

Try and get it replaced under the warranty they offer.

My usual advice is get rid of the card and buy a lexar, I really hope Lexar have not subcontracted their card division to sandisk!

Go with a Toshiba SD card...made in Japan...no issues.

So basically, there is no guaranteed way of getting an sd card that will work from any manufactuerer!

It is a lottery no matter which card you buy.  Just make sure you can return it if you hit problems.

actually, I think it\'s just sustained writes... maybe even some formats
(ext2 vs vfat?) ... My plan is to use the thing for like mp3 source...
not a heavy read/write scratch pad.

Wanted to throw in my 2 bits here... I purchased a Sandisk 256M SD card last year, and it began failing miserably on me withing the first week.  By the end of the week the card would not even reformat in my card reader.  There were a large number of similar complaints around the same time period, all related to Sandisk 128M and 256M cards.  The interesting thing was that I found someone who had the same card with the same exact date stamp, and his was working fine.  So it appears that the cards were randomly failing.  I exchanged my card for a Lexar, and have had no further problems.

Now a question... Has anyone taken current measurements from any of these cards?  I\'m not familiar with the technology of serial memory, but I wonder if there is any additional drain from larger capacity cards?  1GB SD sounds incredible, and I have yet to use up my 256M card yet.

I think there\'s a rather huge irony in saying \"Don\'t use SanDisk, use Lexar\" given that I think SanDisk makes the SD cards for Lexar.
Or maybe just the CF cards.
