Sandisk 4Gb read-only on PC

I recently purchased a Sandisk 4Gb microsd card for use with the Tytn II. The card works correctly on the Tytn. I wanted to transfer a large file to the card by means of the card reader sddr-113 that came with the card. I plugged the microsd card into the sd adapter, put the latter into the card reader, and plugged the card reader into the usb port of the PC.
On trying to write the file to the card an error message popped up saying the card was read-only. I double-checked that the read-only tab on the sd adapter was in the correct position to enable writing but the error persisted. I formatted the card on the Tytn but to no avail. Sandisk support does not list any known issues.
Knowing that several users have purchased a similar card for the Tytn II, has anyone encountered such problems, and is there any fix/workaround? Thanks.
EDIT: Note that there is no problem reading files from the card on the PC. Transfer speed in this case seems quite good. MY PC is WinXP.

You might check the microSD adapter. The adapters that are a std sized SD card have the small "read only" switch on the side of the card, you may have bumped it. Mine isn't even labeled, it should be switched forward, towards the gold contacts.
Good luck.

As I said, I checked that the read-only switch was in the right position. That said the adapter may be defective, and I'll try to put the microSd into another adapter. However any news from others with possible the same problem will serve to see if mine is an isolated case or not.

Oops, sorry, yup I'd try a different adapter, they're pretty cheap/fragile. I have only seen this once, on a friends card. The tip is that the native microSd card is writeable in another device so it really points to the adapter.

I am also experiencing this issue with the exact same card & adapter.
GRRR it really take age to copy data across active sync...

I had this problem as well. I later found that my PC wanted me to format the card when reading it with the adapter. Luckily my card didn't have anything important on it at the time. When I pulled the card to use it in my Tilt, the new device couldn't read it either.
I was able to use the card & adapter with a program found in a post on this forum to repair my corrupted card.

Can the Advantage use a card reader?

I'm interested in using the Advantage to have as a mini laptop/phone access/gps and camera card backup device.
As such it would be spot on, small enough to fit in my rucksack but usable in the field.
But can you use a USB or other card reader to backup CF cards to the 8/16gb internal memory?
Edit: Just going to change me request, to who has tried a card reader? As i know it "should" work with one but who has?

Works fine on mine, using a cheap sd card reader.

Its CF cards i'm interested in. So i can back up my SLR images to the 8gb internal drive. Do you know if those work?

Well, I said cheap SD reader, but it's actually one of those multi card readers, and it has a CF slot as well. I don't use CF cards so can't test that, but the Athena reads SD, MMC and Sony Pro Duo cards through it fine, so I have no reason to believe that CF cards won't work.

Just read your post so whipped out the 4 in 1 cable and cheapie 25 in 1 card
reader and yes it sees the SD card NO it will not read the 2 gb CF
card from my Axim51v.

I wonder if it could be that the CF cards sucks more power, then if we use a card reader with an external power source, do you think that would work?
...

Ouch, hmm that could be a killer for me. Thanks for looking though its most appreciated.

Well I used the same reader and CF on my host pc and it works fine.
It's either a power issue or because the 7501 doesn't have a driver
relating to the reading of CFs.

The 7501 should read CF cards just fine - it's more likely a power issue or a FAT issue. I've just tested a few of my cards and found something interesting (I'm using the Dopod U1000) - the Athena will only read one external volume at a time. This was tested with a 4GB Sandisk M2 card with Memory Stick adapter, 2GB Transcend SD (SDIO1.0) card, and 1GB Transcend CF card, through two different multi-card readers, and with both the 4-in-1 cable and dock. All of the cards could be read, but only one at a time. A soft reset was also occasionally required.
This was surprising to me, because I once attached three FAT32 external HDDs to a Pocket Loox 720, and damn me if it didn't mount and read all three. Me being the curious type, I put both card readers through a powered hub and attached that to the Athena - same thing, only one card from one card reader could be read at any one time. I tried the same experiment on my Loox, and it also mounted only one card per card reader, but both card readers could be used at the same time. Just for fun, I added a usb flash drive and an independently powered 40GB FAT32 desktop drive in an external case, both mounted and could be read as well - I had Hard Disk 1 through 4 in File Explorer. At a guess, I'd say the one external volume limit is a problem with the Athena's mass storage driver, or something in the registry.
I also tried an 8GB Seagate ST1.2 CF Microdrive which couldn't be read in any configuration, with or without independent power to the card readers - as this card requires much more power than flash based CF, I'm not too surprised. I have an 8GB CF at home I'll try out later.

I've tried this card with both my card readers - it works just fine. I don't know what's going on with bigtsr's card, but my (flash-based) CF cards all appear to work.

[Q] XD Card Reader???

Anyone have a specific card reader that has worked with XD cards? Going on vacation and my underwater cameras are all XD and would like to be able to view on the A500.. Thanks!
P.S. all of the cards must be FAT formatted... Problem?

@smoothsl.....You might want to look at the "Targus TGR-MSR" I purchased mine in Walmart it was about $13 but I think you can get it cheaper on line. Mine clearly states that it is USB 2.0 and will read/write the following.....XD...Compact Flash...SDHC...SD/MMC...Micro SD...Memory Stick...SDXC. I honestly haven't used it for XD cards, only Micro SD & SDXC but those work perfectly. A note on formatting, if you use the proprietary SD application it may only format it as "Ext" (at least it did for my 64Gb SDXC card) and I found that the A500 wouldn't read or write to it so I had to use Windows to format as Fat32 and this worked fine. On my smaller 16Gb Micro SD there was no such problem.
Hope it helps.

can t you plug onto USB your camera ?
just asking, like with a cable, if yes well you normally will be able to get all picture on the tablet and import them without need of another Card Reader.
Else you need one on USB

Problems writing image to microSD

About a year ago, my wife got an NC and I installed CM7 on a microSD card. She loves the NC/CM7 combo. A week ago, I got a NC for my birthday. But I cannot get write the image to the microSD card. Any and all help would be appreciated.
My problem is that when I try to write the image to the card (on Win7, using three different image writers), I get the error message that says "Error in writing disk Disk 1, error 5, access is denied." I have browsed all the threads and searched them. I have also searched the internet. It seems that the problem is that something else is accessing the microSD card, or at least the image writer thinks that that is true, and write access is denied.
I have browsed all the NC threads on this board and searched the internet. It seems that the most common response was to use a different image writer. I have used WinImage, Win32DiskImager and RoadKill. I get the same error message on all of them. I have tried to track down what program/process might be accessing the card, and haven't found any. (Based on my reading in this forum, I have made sure that no Explorer window is open.)
The only advice I've read which I haven't tried yet is to use an external card reader. I have an HP G62 laptop with a built-in card reader. (And it was this system which I used to mod my wife's NC, so I know that the hardware used to work.) I would really like to NOT buy an external card reader, which is why I'm trying to track this down.
Any advice is greatly appreciated. Particularly, is there a way in Win7 to identify any programs/processes which are accessing the microSD card?
TIA
Doug

Why do you NOT want to buy an external card reader? It is most likely the cause of your issue. They are cheap (less than $5) and readily available. EBay has them for 99¢.

brand of the sdcard?
Any tries with different cards?

I don't think I need another thing lying around that I'll use once. But if it solves the problem, I guess it is worth it.

It is a SanDisk 4gb Class 4. I think my next step is to get a new card and see if that works. If it doesn't, then I'll get an external card reader.

SanDisk is absolutely compatible, so the brand is not an issue.

Since you are obviously using an SD adapter to be able to fit it into the PC card reader, that could be bad too. In fact some card adapters have a write protect switch on them to prevent accidental writing.
If you get an external micro card reader you can throw away that card adapter and have one less thing laying around.

Hmmm . . . I have gotten another microSD card (Sandisk 4gb Class 4); that didn't work -- got same error message. So I bought a microSD card reader. And I got the same error message. Win7 insists that something is accessing this microSD card at the same time I am trying to write the image onto it.
That just about exhausts the solutions I've come across in this forum and across the internet. So now back to the last question I asked in my original post:
Particularly, is there a way in Win7 to identify any programs/processes which are accessing the microSD card?
If there is a program/process accessing the card, I can terminate that process. Any help??

I have solved the problem, by seemingly breaking several "rules."
First, after inserting the microSD card into the onboard reader (nestled into its adapter), I then removed the card without properly ejecting it then reinserted it. Second, I then used WinImage to write the image onto the card using the "Write" command (after choosing the disc under the "Disk" menu and opening the image using "File/Open," I then used "Disk/Write"). Everything seemed to work as it should -- the progress bar incremented up until the files were written 100% and all seems to work fine on the Nook.
Doug

Thanks
Many thanks to leapinlar and Rastaviper for helping me through the process of getting this to work. I am now the proud owner of a NookColor which can be booted into CM7.2.

SD and Micro SD card support

Hello
I wanted to know if one plus 5 can read either the Micro SD or the SD card, if I use a card reader for this. I tried with one : https://www.amazon.com/Vanja-standa...martphones/dp/B01JJ1VDQK/ref=cm_cd_al_qh_dp_t
Though my laptop read both the cards (and my laptop has a SD card slot) but none of my phones or my tablet did. So I was wondering if one plus 5 has the support to read the memory cards.
thanks

Well, it has support for USB OTG (on the go), and I have tested the USB OTG with a USB C OTG flash drive and it did work. You have to enable it in the settings first, and I can't get TWRP to see it, but it works fine in file browser apps.

I know, I'm just saying, it has OTG support, which is what the thing you linked is. So in theory, it should work. But no promises.

OK, if you can get an adaptor to fit the sd card reader (usb-A to c), found one in my S8+ box, then you can use the sd card adaptor. Tried with one I have and an older sd card. Read fine...

can you send an image of the connection?
and also which card reader u r using?

It is something like this - https://www.officeworks.com.au/shop/officeworks/p/comsol-usb-type-c-to-type-a-adaptor-cocmafad or this https://www.firefold.com/adapter-us...OJySZV1E44FQIt58RIlHe51HLDHD67YaAv6LEALw_wcB- but all in one with a lexar micro sd reader attached.
I found mine in the Samsung galaxy S8+ box

what why just get a USB-c micro sd car reader. Slide the micro sd card into and plug it in. Forget all the crazy wired adapters. Something like this....
https://www.amazon.com/Lexar-microS...29&sr=8-3&keywords=usb+c+micro+sd+card+reader

Mine allows more than just sd cards - old school usb keys that aren't OTG, possibly HDD's/SSD's and other USB equipment.
If you just want micro sd cards though, that's a good idea....

Hello
Till now I have tried all these sd and micro sd card readers from amazon:
https://www.amazon.com/gp/product/B019PI2WPS/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1
https://www.amazon.com/gp/product/B01JJ1VDQK/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1
https://www.amazon.com/gp/product/B01NBECO3G/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
and I am sorry to say, that none of them work with One Plus 5. The phone does not read the cards at all. Is there something in the OS that maybe does not allow the cards to be read?
I really need something that works, or some workaround, since I have 3 different cards, with lots of my music on them.
2 cards are exFat and one card is vFat, if that helps.
The Flash drive with the OTG cable works OK.
thanks

No idea. I toggle the OTG on in settings and just plug mine in and it works.

Hello
OK I have got it working now. I installed Total Commander file manager and that read my sd card. So now ES File Explorer also reads it. The thing is that I have to keep total commander installed, otherwise ---- Es File Explorer stops reading the card.

Yep, OTG seems to only allow the Stock file explorer toread the OTG devices, nice to know the workaround...
