help 32 gb card keeps deleting files

I just upgraded to a 32 gb memory card and when it prepares the sd card it also deletes some files in some folders that I have. anyone else having a problem with 32 gb cards

Back everything up on your computer and format it.
Sent From My HTC Evo 4G Using Tapa Talk Pro!

what brand card to you have?
Me thinks the OP prolly has a cheap Egay card

it is a sandisk microsd class 4 and I have tried to format it and it still just deletes files for no reason

If its really a class 4 then you might have been duped, as far as i know (as as far as sandisk says) class 2 is the fastest their 32 goes. It could be "deleting" files because the card's been modified to report 32 gigs free space but is actually a card of a smaller size, once you pass the physical limit of the card it still reads as being able to address but there isn't actually that much space on the drive. Try loading only 16 gigs worth of stuff and see if it deletes any files then, and if it still does, go down to 8 and then 4 then 2 and see if it still does the same thing.

A friend bought one off ebay and said that it didn't work either.
I looked at it and after a day of not understanding why it wasn't working, I determined it only really has 2 gigs of real storage space in it.

maybe its fake? download "h2testw" its easy to find on google, and its free. scan the card and you can see the read/write speed and if it has bad sectors and its real capacity

[Q] Quick question on stock sd card size

Hi Guys,
I am having a problem loading some of the new 3.0 roms that are out now...and I was wondering if this might be the issue.
I have the stock SDCARD that came with my evo4g (8gb)...but when I insert it into a card holder in my PC, it only comes up as 5.67gb total. Even when I try to format it...it only says 5.67gb.
Is that normal?
Thanks!

The biggest problem with our SD cards is the type of card it is. our "class" is really low. they SHOULD have put real cards in our phones like class 10. I personally did test both on read and write speeds while in the phone and the class 10 was MUCH faster than the stock. get a 16GB.. btw, it'll never reach 8gb, or 16gb. it'll always be less.

Yes, I understand all that...class, etc...and I know that after formatting it will not be 8gb due to 1024 equals 1gb...but 8gb down to 5.67gb? That seems a little low right?

no. because as soon as you format it and put it back onto the evo... it re-adds its stuff to the sdcard. and also.... the math isn't right. you forgot about the partition table which takes even more away. Depending on how you format it if it is fat32, NTFS, WinFS*I REALLY WISH MICROSOFT WOULD DO THIS! LOL* well, the size of the disk will change. well, I mean the amount you can use. oh and also the unit size can change it.

Do you have an ext partition on the card (for apps2sd)? That's the most likely place the extra space would go. The space you're seeing reported in Windows is the FAT32 partition.
If you don't think you have one, have you ever had one? If you thought you had gotten rid of it, it's also possible you didn't really get rid of it, depending on what you did. Just reformatting it in Windows won't get rid of it.
An 8GB (marketing) card will normally have about 7.45 GB of actual space. So you're missing roughly 1.75 GB.

Empty 64 GB MicroSD card reduced to 32 GB Space available when empty?

I have a Sandisk 64Gb MicroSDHC card. I've been using it for sometime on Android and. I've used Android to format it but never to partition it. I've also used Android to wipe data on the card. I've formatted it varous times again on Ubuntu.
The card was working fine but today, I decided to format and clear all the data on it. Much to my dismay, after when plugging in the card and formatting it, Windows read it to have only 27.8 GB space even though it was empty. Ubuntu also showed 27.48 GB only.
I've not much problems with the card on Android and Ubuntu but today, this serious problem occured. Just how does a 64GB card reduce to 27.48GB? I've formatted the card to FAT32 and EXT4 multiple times to no avail with GParted.
Previously, some time ago, I've formatted the card to FAT32 and because the computer, I forgot if it was Windows or Ubuntu and because the computer read it as having 30GB space, named the card 32GB Volume or something like that (The name has long since changed to one of my choosing). However, Ubuntu still read the card as having 64GB of space and filling it up with more than 30GB worked just fine.
What happened? How do I resolve this? I need the card to work on both Ubuntu and Android.
This is my card. http://www.amazon.com/dp/B005V7WIA2 Based on reviews alone, it seems to be very good quality. I've used the card on Ubuntu, and Motorola Defy (Android), and the Motorola Xoom (Also Android). Both Android and Ubuntu have worked with the card just fine except for one thing Occasionally, when copying files to or from the card, I get an error message. Sorry but I don't recall what the message said.
Also, sorry for this mess of a post. I'll try to reword it once I have the time or overcome my exaggerated grief for this unexpected tragedy.

Use h2testw and check if it might be fake (i.e. actually 32 GB, but re-programmed and re-labeled to say 64 GB).
I got delivery of a new 32 GB thumb drive an hour back and am running the test as I type this. Makes sense to test out all new flash memory purchases as soon as you get them. Lots of fakes going around.
If at all yours turns out to be fake, then you're lucky you got a 32 GB, and not a 2 GB! Hope yours is not such a case!

Anyone using Adoptable Storage? All my old cards are too slow...

My cards say class 10 and 50 MB/sec. Android says they are too slow.
How fast of a one do I need?
I don't want to buy a 128 card just to find out I need root to tweak the buffer or that it doesn't work that well.
I posted a screenshot. Adoptable is the same as storage, sdcard, 3dots, format as internal

From my understanding there aren't any cards at the moment quick enough to serve the role efficiently. Just use it as an external storage until faster cards become available.

I was about to make a post concerning the best Micro SD cards do Moto Z Play, thanks for bringing that up!
I have a 128gb Samsung EVO micro sd, class 10, but it's 48mb/s and I got the same message you did, saying the card isn't fast enough and that the overall apps and system speeds could be slower.
I thought class 10 micro sd's were among the fastest and the Moto Z Play wouldn't have any trouble using it as an extension of it's internal storage, but as a matter of fact, there are indeed faster micro sds. After researching a little bit, I found Samsung EVOs with 80mb/s transfer speeds (the 48mb/s are colored orange, as the 80mb/s are little green ones):
I still haven't bought one, but I browsed through some forums and videos and people with the same problem said 80mb/s seems to do the trick and they didn't get any message complaining about the micro sd speed.
f you want even faster micro sds, try the Sandisk Extreme, with speeds up to 90mb/s:
I have to get a faster micro SD anyway, as soon as i do i'll post here my experience with it.
Hope this helps,
Cheers!

While running the adopted 50 MB card AFT fails on most copy operations.
I am afraid ? that 2 times faster may not be enough for the already challenged ATF, buggy as it is already.

Better?

Using this card with no issues. Formatted as internal storage. SanDisk Extreme 128GB microSDXC UHS-I Card with Adapter (SDSQXVF-128G-GN6MA). Got it at Amazon for 60 bucks. It is quite speedy as far as I can tell.

Do you play large music files (flac or dsf) ?
I do and getting them on such a card is via my Mac using Android File Transfer or from a SATA drive using OTG. On KK AFT did not work on large transfers. It has not been updated in many years. The OTG / drive method should be reliable but not with my 50 mb, slow card.
To boot, on the negative side of using adopted cards, you cannot pull the card in the case of a data wipe.
I will be abandoning this method.
Thanks to all for sharing!

In my use case, adaptable storage doesn't make much sense on devices with 32gb or more of internal storage. Unless you really need that much space for app installs, the limitations outweigh the benefits. My typical app load is around 8 to 10gb, so I have somewhere around another 10 available on the MZP, as long as I pull all my media into an external card. This way I know all my apps are using fast internal storage, and I don't have to wonder if a widget is available or not. And I can pull the card and use it in a PC or other device.
Now my Moto E 2 (with 8gb onboard) is a different story. But I use a hybrid card in that - 20gb as adopted and the other 40 as external. May consider this as an option when I get around to getting a card for the MZP

I took a 32gb card and combined it. It warned me too. After reading up on the function, Android evaluates what to put where. Having the card separate made it less useful only good for photos and video really. This way app data can be buffered there. Things like cloud services buffer files internally. Netflix now uses SD but that was an issue too.

Bought a new micro SD for the Moto Z Play and it works perfectly with no warnings about it's speed being slow!
It's a Samsung PRO 64 GB microSDXC Card, with 90 MB/s reading speed and 80 MB/s writing speed.
As you insert the card and format it to be part of the phone's internal storage, the system doesn't complain about the card being too slow or that it'll affect the overall app and system speed.
It's perfectly reliable for installing apps outside the device storage and keep the desired speed and all that good stuff.
Cheers! =)

It's a microSD. For these kind of cards it's quite usual that there is some percentage that fail after some time. Some cards only last for months, other years. It seems to be independent of manufacturer.
My personal advice: Whatever you store on a micro SD card, have a backup. I'd rather not use it for internal storage if it's not necessary to do so. It's slower than internal memory anyway. This is a personal opinion, you'll have or see different opinions for sure.

I agree but for me having a Mac I never want to use ATF it is buggy.
So I am left to getting large music files from an external drive over OTG.
It is so much more reliable to drop the file right to the SD and move the card to the phone.
If the adopted card fails , you need a data wipe or an update screws it up, you have a bad phone day!

I'm allowing the access via Windows filesharing (still OSX 10.6.8), and then access some drive on the computer using LAN plugin of Total Commander for Android. Works like a charm! It is a bit slower, but very convenient not having the need to put card or, put card in etc.

I'm quite sure that file sharing via smb: is available on nearly all versions of Windows and OSX.
You may start Windows file sharing in network settings of OSX. Then you can give access to some drive in Finder.
If you google a bit, you will find help I guess.

Buy? Total Commander is free of cost, including all necessary plugins. For Windows file sharing (smb) you need the TC LAN plugin.
Edit: By "a bit slower" I meant because it usually is being used via WLAN in your intranet

Just wanted to post back here - finally got around to picking up an sd card for the MZP. Went with Samsung evo 128gb, $40 on Amazon. Since it's got plenty of space, I decided to go the same route that I did with the moto e, and do hybrid storage. Formatted 25% adopted and 75% external. Gives me an additional 30gb internal space and 90gb external storage.
Device sees the storage space fine. A couple apps I've messed with so far (Netflix and Google play music) can save to external fine, but don't recognize the additional available space in "internal", or at last don't report it as available.
I don't plan to move any apps that I use frequently or anything that I use widgets from to adopted, as the advertised max read speed is only 20mb/s. Haven't actually tested yet. But I did move a couple low use apps over. Reported storage space on both internal and adopted updated correctly (an issue I've had in the past).
So far, so good.

HTC 10: A devourer of SD cards?

Hi!
Today my SD card died and took some pictures with it to the grave, fortunately nothing very important. It may not have been the most expensive card, but it was a fast one and I used it as internal storage. It didn't show any signs of deterioration before it died. I tried to read the card with my PC and two tablets but none of my devices is able to even see the card.
Before buying a new SD card I want to ask a few things:
Does the HTC 10 have more problems with SD cards than other phones in your opinion?
Should I use my new card as internal storage again or do you recommend to use it as external storage?
Is it worthwhile to buy an expensive card? I laid my eyes on this one: SDSQXCG-064G-GN6MA (SanDisk Extreme PRO microSDXC Memory Card Plus SD Adapter up to 100 MB/s, Class 10, U3, V30, A1 - 64 GB). It costs about 50€.
I hope that you want to share your thoughts with me.
Regards,
Benjamin

If the card was inexpensive and fast, I would think that the compromise made was on build quality/reliability. Using the card as internal storage will wear on the sdcard more than using it as external storage (more reads/writes, more heat) because it will store apps and app data on the sd card.
I don't think the HTC 10 has a problem with sd cards, I haven't heard this issue come up before.
If you have enough space for apps on the internal storage, I would recommend keeping the sd card as external storage.
However, if you still need to use a card as internal storage, you definitely want to get a more expensive card.
Sandisk extreme pro is a good choice because it's made for use with devices like GoPros that do constant writing for extended periods of time, meaning that they can handle the heat that builds up when constantly writing to the sd card.
Sometimes it could really just be pure chance, maybe you got a bad card that died early, but I definitely think it would have lasted longer as external storage.
I'd be interested to know if anyone else has had a similar problem with any phone with an sd card as internal storage.

The thing is - current sd card technology is not suitable for adoptable storage. Multiple read write proceses are killing memory cards. So, until someone makes a card that can take the beating of multiple read write proceses, just use your card as it's ment to be used - as a removable storage and you'll be just fine [emoji6]

Thank you both for your well formulated and competent response.
I've taken all these points into consideration when I chose to use my first SD card as internal storage. I really would like to know if a high quality card could last the expected lifetime of my HTC 10 when using it as internal storage. I wanted to avoid the limitations Google imposed on write access to the external card but when I saw the limitations of the internal storage solution I was unsure if it was a good decision.
It's good to hear that you do not have the experience that the HTC 10 has a problem with SD cards. With that information in mind I can buy an expensive SD card with good conscience.

Let's hope that more users are going to share their opinion with us.

I've just sent back my second SanDisk Extreme PRO card in 18 months. The first one stopped working after just 4 months in the HTC 10, the second one a few weeks ago. The circumstances were identical, I wrote larger amounts of data in a short time and the phone started saying that the card has to be formatted. I could use a reader connected to my laptop to get most of my data back, but the phone insisted on a format. I'm not sure if it was the SanDisk cards or the phone, either way, I ordered a Samsung card this time. Luckily amazon.de is extremely customer friendly and just gave me my money back in both cases.

I always use transcend, I've had a 128gb external SD card in since may 2016, all camera shots goto external card, all flashing and backups goto external card. Never had a problem, touch wood ?

Guys, are any of you using Spotify? I have consistently had microSD cards die after downloading songs for offline use i.e. two phones and three different microSD cards.

I use a Samsung evo card as removable storage since January, never had any problems with it. They are a bit more expensive, but it is worth it in my opinion. I use it mainly for Spotify and Netflix downloads as well as pictures (wallpapers) and ringtones... Don't use a rather inexpensive card as adoptable storage, since they are too slow. Or even expensive cards for that matter In a few years, sd cards will be fast enough, but not today. Also, I fail to see a practical use for using the card as adoptable storage as of right now since 32 gb are plenty of space for apps

I'm going to buy a card produced by a reputable company this time, for sure. But I thought that cards with the A1 specification (Application performance class] would be fast enough for use as adopted storage. But you are right, 32 Gb is a lot of space for apps.

Actually, if Spotify recognises your sd card as removable storage, it even is the default setting

I've used Samsung evo and Sandisk Ultra Extreme and the both failed a short time after downloading Spotify songs!

I've had a Transcend 64GB card fail after a few months. It was inserted as external storage and I was able to recover its contents on a PC. I was able to put it back in the phone without formatting it, just tried a few times until eventually it worked.
It happened when it was very hot outside, not sure if this is related or not. I wonder how many failed cards are failing during hot weather, during heavy phone use, or in hot climate areas.
I've switched to a Samsung 128GB evo plus now, u3 speed, so far so good. Fingers crossed. Judging by this thread though, it does seem that this phone kind of eats through SD cards.

This is precisely what I wanted to know in this thread. Before buying my first card for the HTC 10 I read a number of threads that suggested this phone specifically has problems with cards bigger than 64 GB. But the reaction to my thread doesn't seem to be so hysterical to me.

I been using a Toshiba Exceria M302 128GB as external storage since the phone first launched and it hasn't failed on me yet, touchwood. Although I only been using up to around 50GB usage, I have re-download my Spotify collection a couple times.

The SD card in my HTC 10 is going on 15 months old, and it's still ticking. I have never used it as adaptive storage. It just stores photos taken on the camera (which are backed up to Google Photos). Some games offer to save data onto the SD card, so I do that as well. It's a Samsung 64GB PRO (class 10).
Not sure if the UHS-1/3 cards will fare better.
