Procedure to Mount ejected Memory Flash Cards without reinserting or rebooting

The following Terminal command works to Mount ejected USB flash drives without reinserting or rebooting:
sudo kextunload /System/Library/Extensions/IOUSBMassStorageClass.kext ; sudo kextload /System/Library/Extensions/IOUSBMassStorageClass.kext
Source: http://ask.metafilter.com/241301/Mac-Mount-ejected-flash-drive-without-reinserti ng
yet, it does NOT work for Memory Flash Cards like the SanDisk Extreme 128 GB SDXC Class 10 UHS-1 Flash Memory Card 45MB/s SDSDX-128G-X46
http://www.amazon.com/SanDisk-Extreme-Class-Memory-SDSDX-128G-X46/dp/B00720TE1M
How to accomplish that with such Memory Flash Cards in Mac with OS X 10.8.4 (Mountain Lion)?
Is there a procedure that could work with both USB flash drives and also Memory Flash Cards at once?
Thanks.

OK, I have found this:
re-mount ejected SD card without reinserting
http://apple.stackexchange.com/questions/62478/re-mount-ejected-sd-card-without- reinserting
with the following Terminal command:
sudo kextunload /System/Library/Extensions/AppleStorageDrivers.kext/Contents/PlugIns/AppleUSBCa rdReader.kext; sudo kextload /System/Library/Extensions/AppleStorageDrivers.kext/Contents/PlugIns/AppleUSBCa rdReader.kext
which I belive is wrong, because it generates an error:
(kernel) Kext com.apple.driver.AppleUSBCardReader not found for unload request.
Failed to unload com.apple.driver.AppleUSBCardReader - (libkern/kext) not found.
I think that the right command is this (added space before semicolon):
sudo kextunload /System/Library/Extensions/AppleStorageDrivers.kext/Contents/PlugIns/AppleUSBCa rdReader.kext ; sudo kextload /System/Library/Extensions/AppleStorageDrivers.kext/Contents/PlugIns/AppleUSBCa rdReader.kext
But unfortunately, it does nothing. The Memory Flash Card is NOT mounted.
Any idea?
Thanks.

Accidentally removed SD card without unmounting...all pictures seem to be gone. HELP???

Tonight I received a notification on my LG Ally that my SD card was unmounted (though I had done nothing but pick up the phone). I opened the SD card flap and tried to push the card in to make sure that it was connected...but didn't realize that pushing it in actually pops it out. So, I inadvertently ejected the SD card without unmounting it. When I put it back in, I realized that ALL of my pictures are GONE. Is there anything I can do to get them back, or do I just get to chalk this one up to my own stupidity?

I am having a similar issue in that my LG Ally keeps randomly beeping and stating that my SD card has been removed without being unmounted. It of course is still in the phone mounted. I have removed it and reset it and it was fine for an hour or two and then it stated it was removed without un mounting again. This has been happening repeatedly. it has happened before, but just randomly, and now it is happening more frequently. I am also missing photos(in my gallery), while in this state, although some of the photos that are stored on the SD card are contact photos which are still present. My concern is not my photos however, i'm more concerned about why this is happening not what is happening.

HELP! I need to be able to remove power from a PXI chassis and replace a card without rebooting the whole system

I do not have particulars on the controller, but I am sure it's an NI chassis
and NI regular controller that has a serial cable leading back to the PC.
I am making this PXI rack into a debug rack for instrument cards,
so I need to be able to remove power from just the PXI chassis
and then replace the card with another one
or the same one and then turn the power back on and restart a
diagnostic test on the card WITHOUT
having to reboot the PC.
Is there a PCIe bridge setup that would allow me to do this?
Is there software that I need that can accomplish this?

Yes
The Chassi is a NI PXI 1045
and the controller is a NI-PXI-8331
Let me re-enumerate my requirements:
Background:
I have a number of NI cards as well as other manufactured cards in the system.
One of these cards in the NI system is considered to be a UUT.
That is, I am using the NI card cage system and other cards in the system to test a CARD
during a manufacturing test of said UUT CARD.
The UUT uses a PLX 9030 for it's PCI interfacing.
This UUT is not designed for hot swap, and I do not bieleve it is plug and play.
Requirement:
1. I need to be able to shut off the chassis and remove the UUT when the test finishes, replace the tested UUT
with a unknown UUT, re-apply power and then test the new UUT WITHOUT having to reboot the PC.
I have tried several things, such as disabling the PCIe busses in the windows control panel, and then removing power
replacing the UUT with the next one, re-applying chassis power and then re-enabling the bus and SOMETIMES it works.
I need a very robust way to do this.
I also bought a CHROMA PXI-52906-E extender card with bus switches on it, so that I can remove power to the UUT
without shutting off the chassis. The card is supposedley designed so that when power is re-applied to the UUT, the necessary
signals to boot the PXI PCI interface is conducted, but I think something else has to be written to the card's PCI registers.
I am by no means an expert in PCI/PXI,
but I seem to have exhausted all of my reserach online in how to meet my requirements.
Perhaps there is a way for the NI8331 controller to capture PCI configuration data to the card's on system boot,
and then "replay it" to my UUT after I re-apply power to the UUT?
Or perhaps PLX makes such a tool?
Any ideas?

How to programmatically eject a removable disk (such as a flash card)

I need to be sure that after copying files to a flash card, the card buffer is actually shuffled to allow for safe removal of the flash card (the usual 'eject' option in Windows Explorer). I understand that there is a DeviceIoControl command. Is there anyone who already developed and tested such code?

SUMMARY
Win32 applications that run on Windows NT can programmatically eject media from drives that have hardware support for media removal. However, they must do so correctly to avoid corrupting the media. This article explains how to eject media correctly on Windows NT.
MORE INFORMATION
Windows NT version 4.0 and later support ejecting media formatted with NTFS and FAT file systems without shutting down the machine. Windows NT 3.51 and earlier support the ejecting FAT formatted media without shutting down. However, Windows NT versions 3.51 and earlier do not support removing media formatted with NTFS while the system is running. On these versions 3.51 and earlier the system must be shut down in order to avoid corrupting data on the media.
When a volume is mounted on Windows NT, there are two categories of read and write operations: 1) data operations performed by applications, and 2) file-system structure related operations performed by Windows NT. The second category is used by Windows NT to maintain the file system itself, such as directory entries of files (for example, file times, sizes, names, etc.).
Win32 applications can use either cached or uncached access to files. Windows NT, on the other hand, caches some write operations to file-system data structures to implement a "lazy-writer" scheme. This allows Windows NT to defer some writes to disk until they are absolutely required. This way, only the latest changes need to be written to disk if the file system data is updated often.
Because Windows NT uses a lazy writer system to update file system data structures on media, the media will be corrupted if the media is ejected while the system is updating this information. To avoid this problem, Win32 applications must take the following steps to correctly eject removable media and prevent possible data corruption:
Call CreateFile with GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, and OPEN_EXISTING. The lpFileName parameter should be \\.\X: (where X is the real drive letter). All other parameters can be zero.
Lock the volume by issuing the FSCTL_LOCK_VOLUME IOCTL via DeviceIoControl. If any other application or the system is using the volume, this IOCTL fails. Once this function returns successfully, the application is guaranteed that the volume is not used by anything else in the system.
Dismount the volume by issuing the FSCTL_DISMOUNT_VOLUME IOCTL. This causes the file system to remove all knowledge of the volume and to discard any internal information that it keeps regarding the volume.
Make sure the media can be removed by issuing the IOCTL_STORAGE_MEDIA_REMOVAL IOCTL. Set the PreventMediaRemoval member of the PREVENT_MEDIA_REMOVAL structure to FALSE before calling this IOCTL. This stops the device from preventing the removal of the media.
Eject the media with the IOCTL_STORAGE_EJECT_MEDIA IOCTL. If the device doesn't allow automatic ejection, then IOCTL_STORAGE_EJECT_MEDIA can be skipped and the user can be instructed to remove the media.
Close the volume handle obtained in the first step or issue the FSCTL_UNLOCK_VOLUME IOCTL. This allows the drive to be used by other processes.
The following code demonstrates how to accomplish safe ejection using the steps described above:

Compact Flash Cards Won't Eject

I'm using Lexar UDMA and non-UDMA compact flash cards. I have the combination Lexar CF/SD pop-up USB card reader. It works on my MacPro. On the new unibody Macbook I bought last fall, there is a consistent problem mounting and ejecting cards of either type. When the cards mount, trying to eject them invariably brings up error messages... The first one says, "Can't eject, some app is using the card", if I do nothing often I get another message that says "Device removed improperly...". Then the card appears to eject, but then won't remount. Just a mess. Was in Africa for three weeks shooting and the only reliable way to download images was USB straight from camera to laptop.
Anyone else experiencing this sort of issue?

I'm not having the same issue, bought thought I may be able to help troubleshoot. Are the Mac Pro and MacBook running the same OS level? (i.e. 10.5.6 like your MacBook is)
Also, are you using the pop-up USB reader on both the Mac Pro and the MacBook?
Last, what are you using to move the photographs once you've got the card inserted, are you just dragging and dropping or importing with Aperture or iPhoto?

Maverick does not mount flash card USB3 sandisk

a new USB 3 64GB sandisk flash card when connected to my 15 inch Retina that has USB 3 connections.
Anyone with similar problem ?
Problem for aplle to fix ?
Download a USB3 driver ? and from where ?
thank you

Update - I have three Seagate FreeAgent GoFlex external harddrives. The two that I have connected to my Macbook Pro no longer can be read. I took the two and connected to another MacBook Pro but it would not read the drivers either. I took my third drive which I have not connected to my Macbook Pro for several weeks and connected to the other Macbook Pro and it reads it fine.
I downloaded drivers from Seagate but it didn't help. I started my computer in safe mode, HD didn't work. I have another drive containing a duplicate of my internal HD (using Superduper) and booted with the backup drive. It would not open the two drives. I'm taking the HD to a friend who has a G5 using an early Mac OS, 6.0. These two drives contain my video files and I need to retrieve the files.
Conclusion: The Maverick on my computer has corrupted the first two Seagate drives.

Photos on SD card missing after removing and inserting card without umount

Hi!
I am running Tiger 10.4.11 on my old Powerbook G4 12inch. I am hoping to get some help on an issue which resulted in some photos "disappearing" from an SD card. The story goes as follows:
On day 1 I plugged in the SD card using a USB card reader to my Powerbook. The SD card mounted correctly and I could see my photos (~100). I then closed the Powerbook without ejecting or umounting the SD card. The Powerbook went to sleep and I then unplugged the SD Card.
The next day I then went and took another ~30 photos with my camera using the same SD card. I could see that I had ~130 photos using my camera's built-in viewer.
I opened my Powerbook and it came out from sleep. I then inserted the SD card into the USD adapter again. The funny thing is that the Powerbook only showed the ~100 original photos still. I then tried to eject the SD card but MacOS showed an error saying that the volume is in use so can not be umounted. I then unplugged my SD card.
Following this I can no longer see the ~30 photos on my camera's display either. I have also tried various file recovery programs on Mac OS 10.4, 10.6 and Vista, none show the ~30 "missing" photos. I have also tried to look for any hidden files using terminal with "ls -al" in all the directories but with no luck. The trash can also is empty.
I am guessing that by not umounting the SD card and then inserting it again the OS was still using old FAT tables or something along those lines (speculating here). The question is, any chance of recovery or any other strategies you can suggest to help?
Thank you very much in advance and best wishes.
Oyvind

You may have been able to try and use Disk Utility to repair file damage on
the SD card's storage; but the actual damage due to improper unmounting
in the first instance is carried over to the last. So corruption of them is likely.
There may be some third party utility for helping restore or recover data
from these camera flash memory cards, that may help. Sometimes, it
may be possible to see if the OS X Disk Utility can try to fix the files, but
that may also change them or make them unrecoverable by another kind
of utility. While I don't have experience recovering lost or erased images
from camera memory cards, I do know such software utilities for just this
purpose do exist. Initially, a few years ago, I noticed a freeware utility was
offered as well as a few shareware downloads that would work, for a fee.
Maybe that is the direction to check into, and see if you can repair and
recover the images which were subject to damage or corruption due to
the improper unmounting and remounting of the SD. These items act
just like any external hard disk drive, and need to be handled the same.
Good luck & happy computing!

IMac refuses to recognize USB with flash card

After I plugin my USB flash card holder, my iMac only occasionally recognizes it and then an error message comes up saying that the flash card was not properly ejected. The message disappears and so does my flash card! I may remove and reinsert it several different times and if it is recognized, I receive the same message.
To my knowledge, I have always ejected the flashcard properly.
How can i get my iMac to recognize the card so that I can use it?
Thanks for your help.
Vernon Snider

If you have not done so since noticing this problem, shut down (power off) the iMac, then start it back up. For hardware, just restarting is not the same thing.
Otherwise, you will have to rule out the possibilities.
(1) The card reader is bad. No way to test this other than to get a replacement.
(2) The flash card is bad. Try a different one to see if it works more reliably.
(3) The iMac's port is bad. If you have some other type of storage device, such as a USB external drive, try it on the same port.
(4) A problem with software (the system). Restart from your Mac OS X installation disc for the currently installed system; insert disc and start up with the C key held down. This will get you to Installer's first screen. Go up to the menu bar, and under Utilities, select to run Disk Utility. Connect the USB card reader with flash card to one of the iMac's direct ports. Does it appear in the Disk Utility sidebar? Does it stay there, without the ejection error message appearing?

Flash card 101

No, not like Secure digital or one of those memory sticks.
I am trying to write a flash card program for memorising japanese vocabulary as my first dev project on mac.
My formal programming education ended after a C- of programming 101 in my local college, but I have been programming for a while now.
The program simply shows japanese word/englisgh word (i hope mac os x has no problem having japanese characters) and then once a button is pushed, shows the equivalent of that in the other language.
Is apple script an appropriate language for this purpose?
I haven't even installed xcode yet, but I have a couple questions:
1) how do I do interface with interface builder? this would be my first project with GUI.
2) how do I store the words combinations in a "database" ?
I can image something like this:
wordsdatabase.txt
1:neko:cat
2:inu:dog
and so forth, but i don't know how to implement it.
Thank you for reading and replying!
P.S. Why not just use paper, pencil and scisor? It's more fun this way LOL

Is apple script an appropriate language for this purpose?
Plain vanilla AppleScript could possibly be used, but the app would be somewhat clunky because AS doesn't offer much flexibility with it's GUI user interaction.
On the other hand, if you want to learn and use AppleScript then an _AppleScript Studio_ application might work pretty well. AppleScript Studio is basically AppleScript + extensions for most of the Cocoa GUI elements so it gives you almost as much flexibility with the GUI as a native Cocoa app would. AS Studio apps are also written and built using Xcode (rather than Script Editor).
But if you've done C based programming in the past then there will be a learning curve for AppleScript. But for that matter, there will also be somewhat of a learning curve to start using Obj-C and Cocoa... it depends on what your level of experience is.
1) how do I do interface with interface builder? this would be my first project with GUI.
This is sort of a vague question. When you create a project in Xcode any of the project templates that generate GUI applications will already have one or more basic/generic Interface Builder files included in the project. You just double-click them within Xcode and they'll launch IB for you.
It'll probably make more sense once you install Xcode and start playing with some of the examples. And once you've fiddled with IB a little then you'll probably have some more specific questions.
2) how do I store the words combinations in a "database" ?
I can image something like this:
wordsdatabase.txt
1:neko:cat
2:inu:dog
and so forth, but i don't know how to implement it.
This is something you'll need to decide for your particular case.
A text file like you've indicated could work.
You might also consider using a property list (.plist) file. Cocoa has some built in methods that make loading an entire plist file into an NSDictionary object really easy. In addition, the Xcode Tools installer will install "Property List Editor" which you can use to manually create/edit property list files.
Mac OS X / Cocoa also includes "Core Data" which is a data storage and retrieval API that includes support for both XML or SQLite built in. This may be overkill for your particular situation but you might want to consider looking at it.
If you decide on AppleScript or AS Studio you could potentially use a "list of lists" where each sublist contained a Japanese word and it's English equivalent. Something like this
property wordList : {{"neko", "cat"}, {"inu", "dog"}, {"x", "y"}, ... }
-- iterate thru the words and spit them out to the event log
repeat with wordPair in wordList
set japaneseWord to item 1 of wordPair
set englishWord to item 2 of wordPair
log("Japanese: " & japaneseWord & " English: " & englishWord)
end repeat
-- Generates output like this in the event log
(*Japanese: neko English: cat*)
(*Japanese: inu English: dog*)
(*Japanese: x English: y*)
But the above example has the words contained in a property of the AppleScript in which case you'd have to edit and modify the script whenever you wanted to change your word list. It might be a better idea to keep your words in an external file of some sort so you could update your words without having to modify your script/program.
There are lot's of possibilities.

I have Photoshop Eleent 12 and use a Windows PC. I hae been using a Canon EOS 50D for several years, which uses a Compact Flash Card. I have always downloaded pictures by using a card reader wich I connect to my computer. I Go to the Organizer, click on "Import" and select "From camera or card reader". Once on the Photo Downloader, I select the pictures, chose the folder and click on "Get Media" and all the photos get downloaded. Today I folled the same procedure as always, but ZI'm gettig an error message that reads"Import Failed" followed by another message that reads "Nothing was imported. The file(s) or folder(s) selected to import did not contain any supported file types, or the files are already in this Catalog." I'm puzzled by this message and don't know what to do o get my photos. Any suggestions?

The organizer doesn't care where you send your photos when you download them via the downloader or where they happen to be when you first bring them in if you use the Get Photos command, but once your pics are in the Organizer, you *must* move them from within organizer or it can't find them. You don't have to use My Pictures at all if you don't want to, but regardless of the folder where you put your photos, if you want them someplace else, you use organizer to do it.

My Macbook Pro won't read my Compact Flash card

Here’s the problem.
Mavericks won’t acknowledge the existence of my Compact Flash card when presented in a card reader (I have tried two readers). It is a card I have been using with Lion on my Macbook Pro for some time quite happily.
There is nothing wrong with the card; it works just fine in our Windows machine and in my camera.
My Compact Flash card is a Kingston 4Gb card. It was formatted in the camera.
The camera was bought approx 2003. Its a digital Pentax Optio 33GS (top of the range at the time shooting 3.2 megapixels!).
On my Macbook Pro 15” (bought new approx 2010) the card does not appear in Finder but does appear in Disk Utility.
The information for the main entry on the LHS in Disk Utility is displayed as follows:
Disk Description: 4Gb Generic Storage Device Media
Write status: Read/write
The sub entry which appears as disk1s1 on the LHS is:
Mount point: Not mounted
Format MS-DOS (FAT16)
I attempted to erase the Card using Disk Utility; I selected the main entry on the LHS and I chose the format MS-DOS (FAT). This returned a Disk Erase Failed msg “Wiping volume data to prevent future accidental probing failed.”
I then tried again, this time selecting Windows NT File system (Tuxera NTFS) as I have Tuxera installed. This did not work either; it failed with the same error msg.
OK so then I tried Mac OS Extended (Journaled) but this failed as above also.
I am not quite sure why, but when I reinserted my card into my camera, my camera could not read the card so I had to reformat the card within the camera.
Oh yes, I also tried rebooting my Macbook with the card inserted but this made no difference.
I have run our of ideas. All help gratefully received.
Thank you. Carol
PS ... apologies to anyone who saw my previous post in which I referred to my card as an SD card when in fact it is a Compact Flash card
MacBook Pro, OS X Mavericks (10.9)
I have this question too (0

Okay, I am making progress here now.
Using the link in my message above timestamped Dec 13, 2013 4:24 AM, I filed a tech support request describing the problem. Because they asked for details to confirm that the problem was with their product, I copied and pasted pretty much verbatim the text from my message above.
Around noon, same day, I got a message back from technical support saying they were sorry for the problem and would provide me with a replacement unit. Two hours later, I got a message from their RMA department saying that because the product has a two year warranty, they needed a copy of my receipt. I located a copy of my receipt for the purchase from Amazon on September 10, 2012 and forwarded that to them.
At this point, I am optimistic that it's going to work out okay. So far, I am very impressed with the responsiveness of Kingston's technical support and customer service departments.
If I actually do receive a working replacement, I will post an update here.

10.5.1: Unable to mount a USB flash drive.

I've seen this problem posted elsewhere, but so far I have yet to see a solution:
After upgrading my MacBook Pro to 10.5.1, it can no longer mount USB flash drives. They show up in System Profiler as well as the USB Probe tool, but do not show up in Disk Utility (and, obviously, not on the Desktop or listed in /Volumes).
I checked the drives on a co-worker's MBP, also running 10.5, and the problem persisted there. The drives mount and work fine under 10.4, as well as various flavors of Windows. When plugged into the MBPs, the status LEDs light up, so they are getting power, and mice plugged into the USB ports work fine.
So, the problem seems to be specific to mounting a USB flash drive in 10.5/10.5.1. I'm not sure if this is specific to MacBook Pros, or if the issue is the same on all 10.5 machines.
Any help would be appreciated.

I have the USB problem. When I insert my USB memory pen, it flashes then stops. The icon doesn't come up on the Desktop, but the memory shows up on the System Profiler.
My USB telephone responds in Skype, but the sound input and output don't show up in Preferences, and so the phone doesn't work.
My Vodaphone USB internet modem won't connect.
This morning, I have no sound at all.
All these problems are resolved if the computer is restarted with the external source already plugged in, but it's a big hassle and must be solvable............

New 128MB Flash card for Nomad

I have a Nomad II with 0 internal memory. I have recently bought a new 28 MB Flash card for my Nomad. I have the firmware upgrade ( got it 2 years ago) and had formatted it. It had problems when I first tried to format it, but I did format it and it worked fine for a whole day (songs on it and everything). Then the next day it does read the flash card. It is weird, it see that it is in there but when I try to listen to music it says there is no music files. I tried the info and it says that there is 2 MB free. Now I tried to reinstall the firmware upgrade and it still has that problem. I don't know what happened. I have 28 MB flash card I have been using for a while and it reads that, but not the new one. Can anyone help?

License info is kept on router nvram, not CF.
In any case your device does not show any additional license to worry about.

Expresscard/34 Compact Flash card reader?

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

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.

Compact Flash Cards

Tonight, after shooting about 650 pictures, I put my compact flash card into my reader and the card gets trashed. I stick a second one in and it also gets trashed..unable to read it. I am attempting to rescue with the SanDisk rescue card.
The only thing different from last week that I can currently think of was I installed two 500 gig Western Digital MyBook Pro external firewire drives and installed the WD Button software and drivers.
Anyone have some suggestions as to what to look for?
I turned off the WD drives and rebooted, but that did not make any difference, and I do not know how to find the WD drivers (these are USB 2.0, Firewire 400 and 800 compabtible drives?
Thanks

After a bit more investigation, I booted my mac from my backup disk (last back up was BEFORE the western digital install) and I still had the trashing of the CF card. I tried both a card from Lexar as well as SanDisk..and from my D70 as well as my D200.
Strangly an old LaCie CF reader, when plugged into the mac seems to work fine running the primary system drive.
The fact that my backup system was also trashing (without WD software installed) and my LaCie CF reader (although I think it is 1.0) seems to work with the primary system drive makes me think that my Belkin CF reader is the culprit.
Has anyone had problems with the Belkin Hi-Speed USB 2.0 8-in-1 reader trashing CF cards?
Thanks
