Sandisk MicroSD Adaptor Problems

Hi,
I recently bought a SanDisk 4 Gig microSD. My former phone (a Hermes with WM 6.0) was able to read the card and show its capacity correctly.
However, when i insert the card into its SD adaptor to use on my desktop or laptop computer, both systems were not able to detect the card.
What should be the problem: is it the microSD, adaptor or my computer systems ?
thanks in advance..

There is a problem reading some SD memory cards in Windows XP and in Vista - are you running Vista or XP or.......?
MSKB article http://support.microsoft.com/kb/939772/en-us gives more information for Vista users.
MSKB article http://support.microsoft.com/kb/921413/en-us gives more information for XP users.
Hopefully one of those will help you
Cheers,

It's probably your SD reader; it needs different firmware to read SDHC. When you bought your SanDisk, you should have gotten a USB-based reader that has the right firmware. Use it -- it will work.

actually, it didn't come with a card reader...it came with an adaptor: should there be a separate driver for the adaptor too? here is the URL of the product:
http://www.amazon.com/SanDisk-Micro...6?ie=UTF8&s=electronics&qid=1191048055&sr=8-7

Definetely problem with the reader. MicroSDHC needs a special reader that usually come with the card.
I bought SanDisk 4GB and I got the reader for free. It works fine with my XP (and fast).

if your in the us there is a great compactthumb drive styled reader at compusa fo 10 bucks. iforget the brand but its a major brand. works fantastic. i got it for the same issue you have

Is it the Iogear brand
please, is this the one:

There are some 4 GB microSD that are not microSDHC.
8 GB ones are microSDHC.
I'm using a sandisk 8 GB microSDHC in my Cruise and everything is fine
On you exact question : what is the difference I know that SD is using Fat FS and SDHC Fat32 FS. There might be other differences, but I don't know what they are.

Did you check the wiki? I'm sure this had to have been covered before

microSD and sdhc
"sdhc" is a standard for microsd/minisd and sd for sizes larger than 2GB. Thus all 4GB and 8GB (and 16GB and 32GB) cards will be "sdhc" to work.
Or if you are talking about an adapter that takes a microsd and converts it into a standard SD, you would of course require a sdhc adapter. Whether you need one will depend on you, using activesync to transfer large files is painfully slow so putting the 8GB microsd in an adapter and putting that directly in your laptop/desktop can be much more efficient.
I use softick's card export to mount the kaiser drive directly on my desktop and can easily transfer larger files efficiently.

SDHC - secure digital high capacity
i don't know what's the difference between sd and sdhc (besides capacity), but there is some difference. however, device specification shows what it supports and kaiser supports sdhc

SD officially doesn't support more then 2GB. There are some out of spec 4GB ones, but they don't work in all devices as it's not an official format. To allow for greater capacity the addressing system has been changed in SDHC, along with the default format now being FAT32 instead of FAT16, and the reader/device must support that to be able to access SDHC cards. Some old readers won't read them for example.
So for 8GB you have no choice, 8GB SD cards don't exist.
But SDHC works like a charm in the Kaiser
EDIT: BTW while we're at it... does somebody else have some performance experience with the SanDisk 8GB microSDHC?
It's a class 4 card, so if we believe the specs this should mean 4-6MB/s write speed.
Now the other day I've bought a little Kingston set with a 2GB microSD, micro to mini and micro to SD adapter and tiny keyring USB microSD reader. The idea was to use the USB reader and supplied card as a USB key always on my keyring, while the adapters would be appreciated spares as I always manage to lose them...
The added benefit over a standard USB key being that I can swap the cards with the phone if I need to transfer large files.
So naturally I've put the 8GB card in the reader and started transferring some files to check the performance. Now that's where it becomes odd... I was getting sustained 14-15MB/s writes on the card! I'm not complaining at all of course, but it just seems rather strange nowadays that something exceeds the rated specs that much when everyone is battling for performance!
I've triple-checked with several large files, purposedly unplugged the USB reader right after the copy ended to be sure there wasn't some caching going on, but no, the files were always readable and complete...
Impressive, I've never seen such performance from either a SD card, let alone a card reader that often are slower than the cards... Even my good and fast USB key is slower than this topping at about 11MB/s...
The SDHC speed classes are pretty obscure though, the 4MB/s are supposed to be a minimum under some precise conditions...

Mny PC SD Card readers are not SDHC compatable, so you'll need to mount them via the Kaiser/Tilt/Vario via Active Sync.

Well one compnay here has 3 different 8g microSD cards..
one is 40eur - 8G normal
one is 43eur - 8G ultra II
one is 53eur - 8G sdhc
so still, which one will be faster in the pda?
i have a SD card reader that supports sdhc, so its no problem getting one of them, just want to know if the card sdhc will be slower in the pda couse of the secure stuff?

Normally, the 16GB micro sd card should be in stores this month.
If you have the time and money, I suggest you wait a bit longer and get one of those...

speed of the sd depends on it's class rating:
What is Class Speed Rating?
The SD Association has created and defined 3 speed
classes to help you identify speed and performance
capabilities/minimum requirements of SD/SDHC,
miniSD/miniSDHC, and microSD/microSDHC cards and
the host products. The SD Speed Class Ratings specify
a minimum sustained write speed for
SDHC/miniSDHC/microSDHC cards (Class 2: 2 MB/s;
Class 4: 4 MB/s; Class 6: 6 MB/s*).

You most likely won't be seeing a difference. PDAs are usually not capable of accessing a card at more than a couple MB/s, way less that what cards are capable of.

ok thanx... so cheaper / better
maybe ill wait for those 16g, if the phone will support it...
now im using card for navigation (need 2 gig), for pictures (cca 500megs), for Mp3s (cca 1 giga) guess 8g is more then enoug anyway ....
will get the cheapest, hopefully it will be readable on all sd readers
thanx everyone.

As said before, 8GB SD cards do NOT exist. Even if not noted by the vendor, any 8GB card will be SDHC, and will require a SDHC-compatible reader.

For my Polaris i'm using this one : http://www.amazon.fr/Sandisk-Carte-...2?ie=UTF8&s=electronics&qid=1215248577&sr=8-2
Works good. Transfer rate is not too bad.

16Gb micro SDHC working

Not seen any mention of this so far - can happily confirm my new 16Gb Sandisk micro SDHC (from mobymemory) and my micro-mini SD adapter (from a HK ebay seller) work in tandem on my Ameo.
Was sceptical they were going to work - no idea what I'll do with all the space but this seemed like a sensible upgrade.
Used space 32.0Kb
Free space 14.8Gb
Have read of some problems with micro-mini adapters and I had a couple of issues myself. Couldn't read a 128Mb micro card on my Ameo, and my new adapter doesn't work with my PC mem card reader - need to plug the 16Gb directly in to the micro slot, rather than via the adapter in the mini slot.

Thanks for the note. I know I'm buying one shortly. I can use all the space I can for pix & movies of the newborns (and the music.. and full movies.. etc)!
Good to know it will work!

Which micro mini SD adapter did you buy? I am looking for one too.
QAN

I bought mine for £1.50 from overseabridge, search for "MicroSD to miniSD adapter converter SD card - FREE S/H".

I purchased also one 16gb microSD fron mobymemory and works flawlessly in my X7500 with the miniSD adaptor. The sequential max speeds (in a PC) are 18MB/s read and 14MB/s write and this make it a very serious option to upgrade the storage capacity.

Great upgrade!
Can confirm too that this card works without a hitch. Filled mine to within 150mb of max (audiobooks, music, video, photographs & programs) and saw no problems at all. My X7500 now has 24GB of memory! I'm now using the 8GB microdrive as a large file transfer solution.
Buckle my shoe!

Is that possible? I heard it's a Class 2 card (= ~ 2MB/s read/write).

Yes, is possible, i used two different benchmark programs ans the results are almost identical.
Also i used Total commander (this program have a transfer speed measure utility) copying large files from and to the card and the result is 18 MB/s in reading speed and near to 14 MB/s writing files.
The specifications says Class 2, but really are more than a Class 6.

thanks, good to know. looks like it's on my Christmas watch list.

hi, I think You are wrong. Class in SD specification meens the minimum transfer, not maximum. If You send large files, transfer is different, much bigger. If You send a lot of small or very files and the card is fragmented the minimum transfer can be about 2 MB/s in class 2.

thanks for telling me that. I have a class 2 and a class 6 card, and when I write a 700 MB file to each, the class 6 card takes about half the time as the class 2 does. that said, the writing speed of the class 2 card is definitely faster than 2 MB/s, so your explanation is at least partially true, I think.

It depend of card, for example SanDisk microSDHC Ultra 8GB Class 6 write 18MB/s, read 20MB/s, and SanDisk microSDHC 16GB Class 2 write 14MB/s, read 20 MB/s it is maximum speed of the cards. Minimus speed is during write small files.

I have on my Advantage 7500, WM 5.0, a Sandisk SDHC8GB with adapter micro/mini SD.
My 7500 read the SDHC8GB, but:
- the available memory displayed on my 7500 is only: 3700 Mb
- My 7500 could only open first 4 Gb files
- the others 4 Gb on my 7500 are visible but not available. If I tap on those files my 7500 isn't able to open it
I ask you:
- are you sure that all the 16 Gb in your Ameo are available? If you fill completly the card an then you tap on all the files, the Ameo open all the files?
- if really you can open all the files coul you tell me which brand of adapter micro/mini SD are you using?
...

In my X7500 the system shows the whole available card capacity (14.8 GB). I filled the card with large and small files, the X7500 is perfectly able to read and write in the MicroSD without any problem.
I hope it solve your doubts.

Your 7500 has Windows Mobile native 5.0 or you upgraded it to 6.0?
Wich brand of adapter micro-mini SD are you using?
And where can it buy?

I upgraded the X7500 to WM6 and the MicroSD to MiniSD is one unbranded.

It's possible with an HTC 7500, Windows Mobile native 5.0 (without upgrading to WM6.0), to use a Sandisk SDHC16GB with adapter micro/mini SD?
If yes, in wich way?
Thanks

16Gb
I've just plugged a 16Gb microSD card thru an adapter into my 7500, and I can't get it to see the card - all I can find is the microdrive. What important step have I missed out on?

SD CARD size
i was told the largest Card a X7501 could use was an 8GB sdhc mini card, ?
by HTC.
Anyone with an X7501, Please confirm your personal results, Include brand of card and where you got it.

I was looking at this card for my Dopod U1000 wm6:
http://www.buy.com/retail/product.asp?sku=210881762
and getting the Micro to Mini adapter.
Can anyone tell me if there is a better choice out there?
This is Class 6 and 16GB micro.
Thanks!

Hmmmm seems to me like the reader isnt functioning properly, or your computer is having issues with windows built in drivers ( Unlikely ). Have you tried to put the reader/card into another PC to see if it recognizes there ? If not I would send it back under warranty.
The reader and card are certainly paired and made to work for SDHC so there isnt a compatibility issue. It if works in another PC, it would tell me that you may want to back up and reinstall windows. XP does get shaky sometimes with driver issues but not normally with something so common as a card reader.

One more thing. It seems others have had some issues with that specific combo. If you have USB ports on the front and back of your computer, try using the back ones if youre using the front one now ( Or the reverse if that happens to be the case )
**Edit**
Also take the card in and out of the reader a couple times. Some people are saying its a loose connection between the card and the reader's pins that can cause an issue.

I have the same combo that came with a 2GB card, the reader worked fine with my 8GB card as well. However the reader seems fragile. It works very well when it does and is extremely fast, but now as said it has bad contacts with the card. The problem is different than the one the OP has though, the reader is recognised properly, Windows just says "Please insert a disk in drive X:" when clicking on it. If I squeeze the reader with my fingers it does then touch the card and works. Not really usable that way though
