4 GB SD by Sandisk Not quite ready

Well, I just received a 4 GB SD card by Sandisk. I had some problems getting my computers to recognize the card until I found the right memory card reader. After formatting the card, I was able to see it in every computer, including my Imate Jam. I believe it would work in the Jam; however the problem is that every time I transferred a large amount of files, such as music, video, jpegs, etc. I get an error message everytime. Something about a hardware or I/O error. All the computers get hung up on this card and eventually "My Computer" does not respond. Thankfully, the retailer gave me a full refund and I will send it back to him. I really wish these 4 GB cards were more compatible with our memory card readers. My 2 GB SD card from Sandisk works like a charm in all my computers and readers, so I know it must be the 4 GB card.

have you patched you magician like this

if so that's the card problem,try to change another one

I'd suggest insatlling Pocket Mechanic... it has a very advanced formatting utility..
You can choose the FAT system ( 12 - 16 - 32 ) and cluster size ( range between 1 - 512 ) , also you can choose the typical card usage ( for insatnce vidio and multi media, or larg file.. etc. )
and BTW, Happy New Year :wink:

I spoke with the retailer I purchased the card from. It seems that he is able to transfer files without problem using another card he has. The difference is that he is using a Sandisk card reader. I have not tried that since I don't have one. I plan on purchasing a Sandisk reader and letting you know the results. It may just be the card.

I bought a Sandisk Mobile Card Reader which supports USB 2.0. When I inserted the 4 GB SD and tried to format, both my laptop and desktop could not complete the format. I am sending it back to the retailer and he is sending me one that supposedly works. I can't figure out why this card isn't even working with normal card readers and even a Sandisk reader? Both my computer and laptop are relatively new (less than 6 months old) and both have Windows XP.

8 gb memory card???

hey ya'll...
considering purchasing an 8gb memory card for my htc herald, have any of you tried this sucessfully??? the storage memory for the internal memory is not that great as you know and even things that you store in the memory card take up shortcut room in memory...what do you think?? are any of you running the phone on 4 GB memory stick? thanks ...

I have no problems running a cheap 8gb micro-sd from a no-name brand in my HTC P4350,
However, mine does feel a bit slower (yes its possible), since the upgrade from a 2gb card.

Ive been using a 8GB for about 6 months now and havent had ANYproblems with it. I actually had more problems with my old 1GB. It runs perfect!

i have the 8 gb card from amazon and i used it in my shadow and now my wing, its awesome, i keep all my phone supplies there and music, movies, vids, ebooks...keeps on going, lol its worth it, will be looking into the 16 gb soon just to be able to have an even bigger collection for on the go

I've got an 8gig Sandisk SDHC in my wing. No worries at all.

I've got an 8gig Sandisk SDHC in my HTC P4350. And it work´s nice with movies and music.

i've been using a 8gb card from kingston, don't pack it too full or else your phone will lag, i use it for mostly music and i find that when i fill it up all the way it gets a little corrupted
looking @ buy.com for the 16gb cards, 40 bucks...just needs to drop a little moer....

i got a sandisk 8gb loaded with movies, mp3s, ebooks basically everything and it runs smooth

yep..8gb is fine. slower than my 4gb, but not too bad

now using 16gb, no lag. works great

ok..sorry for disturbing the hype, but I need to post this:
I upgraded from 1 to 2 GB and now to 8gb..since then I encoutered issues:
First I copy and pasted everything from my 2gb card onto my 8gb SDHC class 2 card and everything run smoothly..but after some days I realised that all my pivtures I took were gone..than I saw that all folder were weired named--re-named...BUT it changed again and besides that the pixx were gone, all run ok again..
but now..since Yesterday..it is the same..folders re-named..pixx gone and my display says please insert storage-card, but it is included AND I can see the content via file explorer or active sync...its the same with the 2gb card..displays shows the "please insert screen" but I can access via onboard file explorer (fyi all folders are ok..not renamed on the 2gb card)
My idea is, that my simply copy and paste from 2gb to 8gb card was not the proper way to do it..or??
Can someone suggest how to manage this? I have no card reader and I havent found a way to format the 8gb card..to do the copy paste or whatever again..
Any ideas are appreciated!

I have 8, 8gb cards filled and use everyone of them and no problem at all

Did you try right-clicking on the storage card and re-formating it to deault thats what i had to do when i had that problem and havent had a problem since if that doesnt work then you will need to find a cheap usb card reader online....... and if that doesnt help let me know and i might have another solution to help you re-format it

hey phaze, right click within active sync does not allow "format" ..so i tought as well of the card reader thing..or where could I be able to use right click-format option?

do sdhc is correct to use for htc 4350? I hear dform mycard supplier that only sd is usable? so is that my mistake?

New SD card

Heya
i just got myself a brandnew sd card with 32gb capacity and wanted to use it right away. So i just plugged in the old sd card and the new one and copied everything from old to new via Windows.
After unplugging I put in the new card, switched my htc on and was surprised to find only a few directories and thats all. Its like everything got deleted right after unplugging or inserting. I also seem to have problems downloading pdfs with the new card :
any ideas?

Are you sure it is a genuine 32GB card?

well yea oO
Not sure how to find out and make sure though

Did you simply unplug it or did you actually 'eject it'.
Some devices and cards under windows are not set for immediate eject, which means while the progress of copying may appear to be done, it's still finishing up the transfer in the background which would have warned you if you attempted to 'eject it' as opposed to simply unplugging it.
Did you try formatting the card in the phone first, and then transferring files to it? The manner in which windows may format it may not be entirely compatible to your phone especially at 32GB size (at the edge of SDHC support, as the DZ/G2 does not support SDXC).
Also what brand, model, etc etc etc is the 'brand new 32gb sd' ?

Mh I just did a test with H2testw and it says the sd card is probably faulty :/
Gotta do a callback I guess

128gb micro sd card problems

Hello All
I bought a 128gb micro sd card for my z3 compact only to find out that i will need to format the card to fat32, which seems to be impossible now, i cant even format mat it to anything now let alone to fat32.
I have tried as many way to do this as possible but i keep getting errors of "format didnt complete" or some variation of that.
I have tried using cmd prompt, GUIFORMAT, windows disk managment and multiple youtuve videos.
I have read that the phone can take this type of card if you can format it to fat32. If someone has achieved this or has any advice, it would be greatly appriciated.
Thanks

Get a refund as soon as possible. You almost definitely received either a dud or a counterfeit. If you do end up being able to format it (any file system will do) run this:
https://www.raymond.cc/blog/download/did/77/
If that reports it's stable, try formatting it as NTFS in Windows. FAT32 can't handle files larger than 4gb, and exFAT isn't compatible with Android, iirc.

you sir are a great man.
i think the card is messed up, i cant even open it in windows, acting if its not even there. Even in the properties i get no deteials, everything is 0. Putting it in my phone even says sd card is damaged.
I keep reading people have these cards in tehir phones and tablets. Are you aware of a way to do this?
im sending this card back and getting either a smaller one or research into how others have managed to do it.

If it is a sdxc card, u tried to Format it via phone? Never had problems with my 64gb card

I have 128GB card too. Just put it in the phone and let it determine the type it wants. After insert the card, open setting - storage - erase SD Card. Then the 128GB should become exFat.

I have a 128gb SanDisk card in my phone atm. I formatted it to exfat on Windows 8.1 and then inserted it into my phone and formatted it again using the phones format sdcard option. (cus I'm thorough like that)
Currently it is listed as being formatted as texfat.

I'm not sure what you're asking here exactly, but when a card works *properly* you can just insert into basically any device and it'll format it in a few different ways, not unlike a usb flash drive.
I've had your exact problem before, though. I bought a 128gb sd card from a seller with a really high rating on Ebay, but it was for $55 and I should've known better. It was almost definately a 32GB or 64GB disk that had been re-partitioned to look like a higher capacity drive. The 'new' disk would destroy any data copied over to it after a certain limit was reached, a limit that got smaller and smaller the longer I held on to it. I'd format it, start copying, the copy would fail, the disk would eject itself, Windows wouldn't recognize it until formatting it, rinse repeat forever. I wasn't even trying to fill it to the brim, 'just' my 55ish GB music collection. I ended up actually finding one for $80 on Amazon, which ended up working flawlessly.
If you don't mind my asking, where did you buy it from? How much did you pay? What was the seller's ranking and review history like?

I have had similar experiences myself with micro sd cards from eBay. It seems to be inconsistent regarding particular sellers and the quality of the cards. I would imagine there are sellers also getting scammed by wholesalers claiming to have legitimate cards.
Needless to say, I only buy micro sd cards now from sellers that are
A) in my home country, where I know they are bound by local law regarding faulty goods
B) selling brand name micro sd cards in their original packaging.
I might not save as much money by playing it safe, but it's worth it to be able to rely on a product and have a local warranty to back it up.

I've had problems with Busybox installed on phone and it corrupting SD cards somehow, "Busybox on rails" was the fix for me, also it seemed to fix the damaged??? SD card after a reformat.

I also experienced similar problems with my 64gb card. It worked flawless in my Phone for some months, but when i put it in a defective card reader and connected it to my NAS, the card seemed dead. My Phone said the card was corrupted and it wasn't able to format it. My Windows PC didn't recognize it at all. Also "sd formatter" which never failed in the past, couldn't get the card back to life.
So I checked the card with fdisk under linux and I could see, that the partition table was totally messed up. I deleted the partition table and after that the card was working again.
No problems in the last 2 months. And since I have a fully automated daily backup to my local NAS, there is no need to exchange the card "just in case".

SD card issues

My Yoga Book always says that my SD card is missing and I need to reinstall it. I install it as part of the internal storage, this might be the issue. I have gone through three different brands, Samsung microsd card does not work at all for me. Simply will not read, says it is incompatible. The other two work for about a couple hours but then I will reboot and sudenly it will not read and say it is not inserted, when it is. So frustrating. Also when the microsd card is unreadable, I have the second issue of the Book not coming back on after it sleeps or when the screen times out. To get the screen to come back on I have to take out the microsd card and the screen will come right on, but than says " the is no sd card, please insert." Any one else having this issue? I really want to like this little machine but it seems REALLY underbaked.
I have an idea of what is happening with my cards. I have a very good Samsung microsd but the machine first said "This card is too slow" !!! I set up the microsd card as "internal" storage not media storage. Well, the Book formats the card, uses it but on reboot it looses the card and says the card is either "not in" or, the card is "not compatible". So I try to reformat but the Book will not format it and neither will my PC or any other device. I keep getting that the micro sd card is now "write protected" or "cannot format raw data", so now I have two expensive micro sd cards that are completely useless and I am very very upset. I have one other card I can try to use in the Book and format it as "media" instead of "internal" but Im afraid it might raw format it too and Im stuck. AAARRGGHH. Any ideas on how to re-format these micro sd cards?

Hi! Any update regarding the issue? Would be really glad to know if you have resolved it as I am currently experiencing something similar with my Yoga Book (Windows). I have a 128GB microsd and sometimes it suddenly stops recognising it. I've never had the too slow error though. My card was formatted using NTFS.
Wondering whether the card tray design is bad, and if the card gets displaced when moving around. I'll try another card, and will update this post later.

Android must be formatted to fat32, although the best way is to format it in a Android device like your phone if needed. Not sure about your other issues. Is there an update from Lenovo maybe. My card reader is just fine. #knockonwood

Sadly I ended up buying a new microsd card. My two cards that I started with are still un accessible and useless. I format it to Fat32 and inserted into the YogaBook and designated the card as media. It's been working great ever since. Still annoyed that I am out $100 worth of micro SD cards
Good luck to you. I have the Android version.

Hi! (In my case) I think it was due to the "thickness" or dimensions of the microSD. I had one that was slightly thicker than the original card I was using for the Yoga Book. I swapped them, and haven't had any problem since then. Sorry to hear that you had to shell out another $100. That really sucks. Mine was sheer luck. (Thanks to the added "chunk.")
Hope this bit of info will be useful for other YB owners.

Unfortunately I can confirm that ;/
In my case I observed the same...
I have a model with windows. It's EXTREMELY slow! Generally, no just the SD card. Almost impossible to work on it. Lenovo sucks!
According to the SC slot I've tried many different SD cards and always the same... Time of copying 2GB file, calculated by windows, about 672 hours... Only...
This is my second computer from Lenovo, and the last one.

If you're migrating files, try doing small amounts and copy not cut and paste. Otherwise just take the card out and do it on a more robust pc.

I'm using an SD card and it seems to be running fine. Are you using it for something that needs regular access to your SD card? Like, installing Windows or a program on it? Because that will make transferring to and from the SD card very slow, or at least a lot slower than what it would usually be. The technology in the Yoga Book's SD card slot is old, so it can't handle stressful situations.

Hi, Thanks for your answers,
My main HD has 64GB, its not a lot of, so I thought about changing location of My Documents and all my files on the SD card. But after setting of paths to SD the computer froze due to it couldn't read SD fast enough.
So, I decided to move my personal folders back and tried to move files manually.
But the situation is the same :/
Don't you think that transferring of files on the another computer to SD card has no sens??
It is needed for me to move files from YB to another computer, so while I can't do it than the SD slot and whole Yoga Book is totally useless for me.
Do you think, guys, that it is possible to install Android on it?? There is a possibility to boot from the external USB-CD or just USB, but I couldn't find the Android version for YB.
Maybe with Android it will work??
Did someone of you tried to do it??
Thanks

I did delete Windows 10 and try install Android, however, I was not successful in getting it usable. So right now, Android is a no-go for those who have the Windows 10 version (although, you can install emulators that allow you to run Android apps). I usually try to minimise how many things I have on my Yoga Book - keeping apps to a minimum, and I've got my Downloads and Documents on my SD card and it's fine. Maybe your SD card is an old one?

Believe me, I've tried all possibilities, which came to my head
I bought three different SD cards (actually I have SanDisk Extreme microSDXC UHS-II, 128GB, formated in exFat) and nothing.
I tried also to run linux, and I noticed a small difference in relation to Win10, that in linux the copying process is pending all the time, while Win10 is breaking the process every time and ordering me remove the write protection.

Hi guys,
I found a solution!!!
I don't know why, but I created two 64GB partitions (almost, just 50% and 50%) on the card and formatted as a fat32 and.... Suddenly it works!
Thanks for your attention!

Has anyone tried the 200GB or 265GB micro SD cards yet? google search seems indicate that it might work but not able to get any concrete proof.

Yes, I use a Samsung 256GB micro SD card fine in my YB. Insert it and format it using the YB and it'll format it as FAT32. Only problem with that is I need to convert/compress my larger than 4GB movie files to something smaller.

thanks to PPC_Ed's confirmation, I ordered a 200GB drive and was able to get it working on my Yoga Book Android.

I bought a cheap 512GB sd card on eBay for less than $12 from China. I have stored tons of stuff on it. Downloaded a 1080p movie onto it using the adapter on my laptop and the lap top wanted to fix issues. It did, and everything still is fine. It actually might not be 512gb, but I have more than 200gb on it and it works fine - no speed issues at all. Android still reports 512gb total capacity (499 gb). I couldn't be happier with the $12 spent.
