Flash card read only

I have not been able to write to 2GB SD flash cards. They attach as read only devices. I have tried two different manufacturers, Kingston and Crucial. Both of the cards are FAT 16 formatted. I can read and write to some 512MB SD flash cards that I have. Is there a size limitation? I did not see anyone else with this issue when I searched the discussion groups. Any help is appreciated.

A bit late for the original poster, but ... for anyone else searching for help now, like I just have:
I've just had the same problem, thought it was because I recently installed Leopard. Checked the Lock switch on my SD card, and it was set to allow writing.
In the end, I tried flicking the switch on the card to Lock, then back, and that resolved the issue. The internal mechanism must have been in a different position to the visible switch.

Satellite Pro A200 - Need Windows 7 driver for flash card reader

I have changed from Vista to Windows 7 on my Satellite A200-20N, and now I can't use the flash card reader in it. I have already looked for drivers, but I only find one for vista, also tried to install it, but was not successful.
How could I use my flash card reader under Windows 7?

Hi
Unfortunately I think you can only use the Vista driver and normally they also work on Windows 7.
Maybe you can explain what not successful means exactly
Furthermore you can try a newer card reader driver from another notebook model, e. g. Satellite A300.
Check this!!!

Expresscard/34 Compact Flash card reader?

Does anyone know if there is such a thing as a Expresscard/34 Compact Flash card reader?
Thanks
Mark

Yes, all pro digital photographers use CF cards and most use FireWire card readers. The rest use USB2 card readers.
Many of us keep a $7 PCMCIA card adapter for emergency backup but rarely use it because it is sooooooo sloooooow. It also takes over your computer not allowing you to do much else during the downloading of photo/files.
Do that a few times and you see the need for upgrading to a new standard.
It would be nice to be able to just pop a card into the side of the laptop without plugging in a reader.
On the other hand - Sprint and Verizon do need to make an Express/Card 34 for internet access. I may be getting a MacBook Pro next month and not being able to connect to the internet from anywhere is my biggest fear, more so than the PhotoShop problem.

Which compact flash card reader (still available) works with core i7?

Help! My card reader died. I'm having trouble finding a compact flash card reader for my iMac Core i7. I'm shooting with a Canon 7D. Any suggestions?

Maybe a bit pricey http://store.apple.com/us/product/H6333VC/A?fnode=MTY1NDA2NA&mco=MjQwODk2ODQ
In essence, all USB 2.0 Card Reader should work (SanDisk for example) as well.

I'm looking for a compact flash card reader that will work with the ipad 4 with the lightning port. please help?!

I purchased the ipad 4/retina diplay 64 GB model today and i need a compact flash card reader that works with it.
has anyone had any luck with this??
thank you.

I found this with a simple Google Search:
http://photojojo.com/store/awesomeness/ipad-cf-sd-reader/
http://www.amazon.co.uk/Camera-Card-Reader-Connection-iPad/dp/B005NN8V3M
But Diovonex is correct, use the standard Camera Connection kit and transfer them from the camera directly as described in this other thread.

USB Flash Drive: Read-only filesystem

Hi
I'm trying to format a usb flash drive using various tools but they all say that it's a read-only file system. The drive is not mounted and I'm running as root. If I try to mount the drive like so with the command
sudo mount -o rw,users /dev/sdc1 /media/myflashdrive
I don't get any errors and when I go to /media/myflashdrive I can see and edit all the files (only as root however). However, any changes are not persistent. For example, if I delete any files or run
sudo rm -rf /media/myflashdrive/*
it seems to work and ls doesn't show anything, but then if a reopen the drive, the files are back.
I've tried this on other computers and even in Windows but nothing can put a scratch on it. I heard something about there being a certain bit in the first sector which can be flipped to make a drive read-only but I think it only applied to Windows.
Any advice would be greatly appreciated, but if I can't format the drive I'll probably use some thermite to toast the data on it.

Hmm. I wasn't very clear: my drive was usable originally but it stopped working while I was using Windows (I just plugged it in one day and it was read-only) and now that I use Linux I thought I'd try to fix it (I have been told that linux can do anything but I'm not so sure). I suppose it could just be a physical error on the drive but it's not got any marks or anything.
Just a thought here, if it was a physical problem, would it be possible to 'reset' it with an electromagnet or by shorting it out or would this just frazzle the chip? Maybe not the right forums for that kind of question.

Why does my Macbook Pro make every flash drive read only?

Anybody else having this problem? I can write to a flash drive once on my Macbook Pro. After I remove it, it becomes read-only, but only on my Macbook (I still have read/write access on other computers). Happens with every flash drive, regardless of brand or size. File systems are all FAT 32.

I'd make a sound too if i was put into a bag haha.
Only thing i could think of it it has a mind of its own or your putting your computer to sleep. Try shutting down your mac before placing in your bag and see if that changes things.

PCMICA Media Card Reader only mounts once per session

After I restart and insert my PCMICA media card reader will show up on the desktop but only once. After I eject the card and reinstall it will not show up on the desktop. The card appears in the menu bar but no where else not on the desktop or in a finder sidebar. It acts like it is permanently ejected. The only solution is to restart which is time consuming during a photo-shoot (Sleep/Wake and Finder Relaunch do not solve this). I have two media card readers one for CF cards and a 4in1 for smaller cards. Both act in the same way and once one has been ejected the other wont mount as well. Both cards worked fine in system 10.3.9. System log does not show any difference in loading when it mounts and when it doesn't.

Well, I tried the hardware test and now we know it is a software problem(hardware checks out fine).
I checked out the Delkin website. That was disappointing. Looks like I need to buy more hardware to solve this one. Worse yet if I spend the $100 for two cards they wont work in my next laptop as I plan to get a MacBook as soon as PhotoShop is Intel ready.
So now the question is what do I do with this growing mountain of unusable peripherals. My business is small but we've bought a lot of macs. Close to 50 now. We had a few before Y2K and just before we replace all the PCs with iMacs and G4's. System 8.6 was great and every printer and reader and camera and scanner and external storage device (some going back to 1989) worked great. Now that we have "upgraded" the software so we can do really complicated things like properly viewing web pages and send authorized email nothing works right. I have faxes (Apple 56k in a G4) that can't detect detect dial tone when faxing but can connect to the internet as a modem. Printers that print fine in TextEdit (PS fonts and all) but can't print out of Excel. Dont even get me started about fonts. The list keeps growing and the only answer I hear is to replace perfectly good hardware with new stuff. Then when I do I find the software wont work. (I had to use a old laptop with 10.3 to run the latest software from Version to set up a friends home DSL.) I need to get out of this loop it is costing more than it's worth.

SSD Flash card reader for proprietary HDD

Hi,
Im an Apple service provider, I have a late 2010 MB Air which is damaged, client wishes to retrieve data from internal hard drive, which is a Flash card, the type that uses Apples proprietary interface (its a slim stick with a connector at the bottom)
Does anyone know of a sled or card reader that will enable me to read from the flash stick?
Thanks
Scott

Yes that is what I understood! As I told you before the Photofast SSD Upgrade Kit comes with an USB3-MBA-SSD-Flashdrive-Reader But it's not longer available b/c of Apple and they don't list it on their website. You can try to find one on Ebay.
Btw. the Taiwan website of Photofast still shows the product: http://www.photofast.tw/products/

Make flash drive read only with no copying

Here is the Situation. I have a 2h video of a high school play that i am editing and selling but with final cut you can only export 480 p video on dvd so i am going to sell hd digital copies on flash drives my question is can i make it so that the flash drive are read only and copy protected so it can't be distributed can i format the flahs drive insuch a way a way that prevents copying?

technicallly, to playback you have to 'copy' content (from stick/disk/whatever to device) ....
So, the harder you make it to 'copy protect' your content, the more inconvenient it gets for your paying customers!
for example, on commercial DVDs I'm 'forced' to watch minutes of promos and 'legal advice', talking to me like I'm a 1st degree suspect No fun! And: When I like to watch/listen on diff. devices. again trouble to 'rip' it (anyone remembering the first slogan for iTunes? "Rip.Mix.Burn." Holy innocence ........... LOL
Forget the few copy-cats. Convince by quality (e.g. spelling ) .
Deliver an excellent product, perhaps bundled with some 'extras' (a nice designed box, with pics/t-shirt/memorabilia/…) And, hey - who copies a school-play????

Please identify your notebook with the p/n on the barcoded sticker on the bottom and state your operating system.
I suggest that you install the essential System Updates for Window 7 for your notebook if your OS is Windows 7 32 or 64-bit.

SD Card read only [Solved]

Hi,
Do not think its an Arch related problem but I have an SD Card which will only mount read-only
mount: block device /dev/sdh2 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sdh2,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
It states card is write-protected it not write locked, of course not being able to write to the card I cannot reformat it.
Just wondered if card was faulty? or can I repair the filesystem on it? [ext3]
Thanks
MrG

ExFat Flash Drive Read Only

I let a friend borrow my 64G Flash Drive and he returned it with a bunch of unwanted files. At first I tried deleting them but all I got was a dull "beep" so I figured I'd just erase the whole thing and reformat. Opened disk utility and it was recognized but the options to erase are greyed out. Looked at the drive's info and it says "Read Only".
I have Paragon's NTSF driver installed thinking that would cure the erase problem but that did nothing. I know no one with a Windows machine so I can't ask someone else to reformat the drive for me.
How do I get the Flash Drive out of read only, erase and reformat to Mac OS Extended (Journaled)?

I don't know anyone who uses Windows and took it to a Coffee House to ask if someone there would reformat it for me. Most of the time I got a 'no' fearing it may harm their systems (???) and those willing to had no idea how to perform a reformat. I figured it couldn't be that difficult on a Windows machine, there must be a disk utility somewhere on the system, but they wouldn't let me look or even try.
I did contact the manufacturer and was told the drive should work under OS X but they have never tested it and would not allow me to return it because the purchase date was beyond the 60-day warranty. I did tell them that I would alert the Mac community about the problem and suggest Mac users avoid PNY flash drives or other drives.
Because it was a 64G flash drive I paid a handsome price for it from Staples. I returned it to Staples and asked for my money back but again, according to my receipt, it was beyond their warranty period. Of course, they took me to the locked flash drive cabinet and suggested I purchase another brand but I was ticked and promised I would not buy another item from them.
I've asked the (former) friend who borrowed it to replace it with a different brand and mailed it to him because it contains all of his files. He has not responded thus far and I doubt that he ever will. Its too bad. I'll never loan another Flash Drive to anyone again, good friend or not.

Can we make the time card read only in OTL?

Hi All
can you please suggest a solution for this? Time entries are coming into time card from swipe machine.
We dont want the employees to modify these time entries on tima card. In other words we want the time card to be read only for the employees. Thye should only be able to view the time entries and submit the time card?
Thanks a lot in advacne
Kiran

Kiran,
There is a set of steps that you need to follow to enable any change to timecard layouts. Please follow the Tc whitepaper to make changes and upload using FNDLOAD command. You will also have to upload them with new layout names and update the same in preferences node.

All SD cards read only

Both the internal Sd reader on my iMAC and a usb external reader read all cards as read/only. If you go to get info, you can't change this setting. In Disk Utility you can't do anything, everything is greyed out. When you insert a card into either reader and then remove it with ejecting, I don't get the error message telling me to eject before removing.
Any ideas any body?

There was a thread from 2009 about this problem: it seems that some sd cards (and/or perhaps some sd card slots) get confused, and indicate read only with the switch at either end, but will indicate read/write status with the switch midway between the ends (perhaps a little bit more toward the unlocked end). This sounds strange, I know, but it worked for me today, with a brand new 64GB card (the first one I've ever used in my 21 month old MBP, which indicated read-only with the switch at either end, but became read-write with the switch in the middle.
