Won't mount CF card reader or accept CD in optical drive

I can not longer mount a USB card reader. The reader power light goes on but it won't mount in any USB port. This began happening at the same my optical drive no longer accepts disks. Insert a disk, and it makes some reading noises, then ejects the disk.

I haven't been able to read a CF card for weeks now on either my iMac or MBA - both computers say the cards are unreadable. This is with both my old CF/SD reader and a brand new one. Both computers read SD cards ok and until recently both read CFs without a hitch.
What give here?

MacBook Pro won't mount mxf card reader

Hi - I have a brand new MacBook Pro. I need to import some footage on MXF cards. I usually use Content Browerser to do this. I have a card reader and thunderbolt cable which work on another MacBook Pro. But it will not mount the card reader at all. I can't see the files or device. Is there something else that I need to install for the card reader to be able to show up?

sorry SxS cards with mxf files obviously... I've downloaded and installed the SxS card reader drivers and UDF drivers and download and install the FCP X integration plugin
and it won't mount

IPhoto 9.5 won't recognize USB card reader.

I loaded Mavericks this week with iPhoto 9.5. But now iPhoto will not read a card reader and gives me a message that the card reader was ejected improperly. When I force quit iPhoto and reopen, it won't open the card reader so I can import pictures. I have tried several times to get it to read the card reader. Any ideas?
Nevermind, I found someone else's reply about Image Capture. That worked!

iPhoto 9.5 immediately tries to "upgrade" my library using the upgrader.
iPhoto 9.5 asks you to run the upgrader to prepare the library for 9.5. It then will update the library to its format.
You need to do the following:
1 - go to your Applications/Utilities folder and double click on the iPhoto Library Upgrader 1.1 application.
2 - select Choose Library, navigate to your iPhoto library, select it and let the upgrader do its thing.
3 - launch iPhoto 9.5 to open and finish the conversion of the library.

I have Mac mini Mid 2010. It will no longer open photo memory card in SD reader. It also won't recognize a card reader device when connected to USB. It never had this problem before. Any thoughts?

I have Mac mini Mid 2010. It will no longer open photo memory card in SD reader slot. Plus, I've tried using a card reading device in USB slot, and it won't open that either. Any thoughts?

Do other USB things work?
Do they show up in Disk Utility at all?

IMac won't detect SD card reader

I have a GE High Speed 55-in-1 Card Reader that my iMac no longer recognizes. Help?

Have you checked to see if the SD card reader is listed in system profiler? (apple menu, about this mac, more info button) it should be listed under Hardware, under USB, it would be labeled some thing like "Internal Memory Card Reader".
If the card reader isn't listed:
Have you tried a NVRAM Reset?
Have you tried a SMC Reset?
If the card reader is listed, but your not seeing the inserted cards:
Have you checked to see if the cards are reconised in Disk Utility? (go to the dock, click on finder, go to the menu bar, click on the go menu, chose Utilties, double click on disk utility) Do you see the sd card listed?

N8 won't recognise USB card reader

Hi, i was wondering if anyone knew which card readers the N8 recognises and which one's it wont. It doesn't recognise mine unfortunately. It's an Integral Mobile Card Reader.
Thanks

This is a tricky subject. The main problem seems to be that most card readers use about 500 mA, while the N8 (and I gather most mobile devices) can only handle USB devices up to 200 mA.
After some searching and experimenting I found an SD(HC) card reader that works:
http://www.mcbub.com/item/SD-MMC-RS-MMC-USB-Card-Reader-Writer-126439/
(I received a black transparent one)
I found it by searching for "200 mA card reader", so if you need another card format this might help you.
Note that for me 4 out of 5 of my cards worked: A Kingston 16GB SDHC class 10 (SD10G2 designation) failed, but four other SDHC cards worked perfectly: 4 GB Emtec class 4, 4 GB Sandisk Extreme III (class 6), 16 GB Emtec class 6 and 32 GB Dane-Elec ProLine200X (class 10)
Another warning: A reader that looks the same as one you've seen or heard that works does not have to have the same internals! So don't order by looks alone, check the power specs (although they are rarely mentioned).

Satellite A20-130: SD R2412 cannot read DVDs burnt in certain optical drives

Hi,
I've got a Satellite A20-130 laptop, running WinXP and Ununtu Dapper in a dual partition. My 2nd laptop is not Toshiba one. When I burned DVDs (DVD+R) with my non-Toshiba laptop and played them in my Satellite it all worked fine.
However, when I bought a new optical drive for my 2nd laptop my Toshiba suddenly stopped playing the DVDs burnt in this new optical drive(I was using exactly the same disc brand and format as before-- DVD+R). I tried the old DVDs (the ones burnt in the laptop before the optical drive hardware was upgraded) and they can still by read perfectly fine.
This problem applies to both Ubuntu and WinXP. Support from 2nd laptop says this sounds like a firmware problem with my Toshiba. I updated the driver for my SD R2412 Toshiba optical drive (which, according to the file manual, seems to fix a DVD-Ram compatibility issue). Now the drive occasionally reads some of the new burned DVDs (after making loads of noise and waiting for ages), but more often than not I get an error message saying the device cannot be read because the format is incorrect or the device needs to be formatted.
This non-Toshiba laptop reads the DVDs it burns using the upgraded optical drive perfectly fine.

Hi
Satellite A20 is pretty old notebook model and after intensive usage it can be that drive is more sensitive. If all this happen occasionally there is no simply explanation why this happen.
I know it is pretty annoying but I do not see any magic solution. At the end you must test it with brand new drive.

Cube won't boot after installing new OWC Mercury G4 Cube optical drive

I recently was given a cube and found out that I couldn't burn music CD's because the original optical drive was read only.
So I purchased a OWC Mercury G4 Cube optical drive as a replacement to allow burning. I followed all instructions, however was a little confused about changing the jumper settings on the hard drive to slave. From what info I could gather I needed to remove the jumper to make the hard drive a slave. However when I looked at the hard drive there were actually two jumpers. I removed them both and now the Cube doesn't boot up. All I get on my monitor is a gray screen. Before replacing the optical drive there would be an apple logo during boot up.
Any ideas anyone?
Joe

Note: if there are two Jumpers on the HDD, usually
only one is used. Jumpers set in a vertical position
DO SOMETHING. Jumpers in a horizontal DON'T DO
anything, they are just in a holding position or
spares. There are the rare exception, but that's the
norm.
For more info on Cubes, you may wish to check out
Cubeowner.com. It is for Cubes only and has a big
FAQ and technical section. Plus, it's friendly, like
here.
Thank you. At least I know that the other jumper perpendicular to the one on pins 50 doesn't do anything.
I'm going to try to start from scratch and see if that doesn't work. If it doesn'r I'll put the old optical drive in and hopefully get it back to where it was
You've been extremely helpful.
Thank you

IDE Annoyance-Please Read if you have 2 Optical Drives

Does anyone else with a multiple IDE optical Drive set up have this problem? Can you verify this using a blank CD?
I have 2 optical drives; A Plextor PX-708A and a MSI CR52-M. Whichever Drive is connected to IDE 1 will not read/recognize a blank disc. When a blank disc is inserted, and the drive icon double clicked in Windows Explorer, I get a “:\ is not accessible: Incorrect function” message box. This error follows the IDE 1 connector on the mother board. In other words, I can move this error to the MSI or the Plextor drive depending on the IDE slot it is plugged in to.
On the Other hand the drive on IDE 1will always read/recognize a disc with data on it (as will IDE 2, along with recognizing a blank disk.)
I have tried the following with no success.
[list=1]
In BIOS having the PCI BusMaster both enabled and disabled
Every permutation and combination of master/slave relationship
Trying single IDE cables
Dual IDE cable in both IDE 1 and slot 2 (The error is still there on the second drive)
Re-installing the OD BIOS on the MSI drive using Live Update
Re-connecting cables
New cables
Checking for bent pins on the IDE 1 slot
Trying both the blue side of the cable and the black side of the cable connected to the motherboard
[/list=1]
I’m out of ideas. Any help would be appreciated.

BAS,
I have the Drives Connected to different IDE ports and the problem follows IDE1 (whatever drive is connected to IDE1 has the problem. However if both drives are connected to either IDE1 or IDE2 one of the two drives has the problem.
Thinking that it was the combinations of drives I tried the same thing with an old NEC drive I had. Same problem... Very strange

My iMac won't mount or even read my NTFS external hard drive

I have a new model iMac running 10.9.4
I have a 4TB usb 3.0 external Seagate hard drive formatted in NTFS.
I cannot get the iMac to recognize it.
I've tried:
- mounting via disk utility: "the disk could not be mounted. try running first aid on the disk and then retry mounting" I haven't tried first aid because I don't want to erase or change anything on the hard drive. It also said I could try verifying the disc but haven't done that for same reasons. It works perfectly fine on my 2009 iMac.
- Finder preferences - external discs is checked
- I installed an app called NTFS-3G which was recommended along with MacFUSE 2.0 but that didn't seem to do anything
The only place I can see my hard drive is in disk utility, but it is grayed out.
Any help would be much appreciated.

You must remove the "NTFS-3g" software.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

Imac will not read cd or dvd in optical drive

When loading a DVD I get the following message "A valid device could not be found for playback [-70017]
I have tried to read a DVd perviously viewed on this machine and it is not showing on the finder window.
If I open Disc Utilities I can see the disc correctly displayed.
Any suggestions

I had the same problem on my iMac. I followed the instructions at http://discussions.apple.com/thread.jspa?threadID=2020977, (Klaus1)
i.e. I used the disk utility to restore file permissions and - after a restart - it solved the problem.

External firewire drive won't mount

I've got an external Western Digital firewire drive that's been somewhat flaky recently, and today my Mac won't mount it.
When I open Disk Utilities, I can see the drive (along with the other drives daisy chained together). When I click on "mount," I get a message saying the drive can't be mounted and that I should try running disk repair. I've run both repair disk and verify disk a few, and each time it says that everything is just fine. However, the drive still won't mount.
Any thoughts about how to get the drive working again?
For what it's worth, this drive is basically my manual backup drive that I use each day just as a safety backup. I don't think I'm going to lose anything extremely important if this drive is dead or if I have to try erasing the drive, but I'd like to see if I can rescue it first before taking drastic action like that.
Thanks!

Dale,
That sounded like a brilliant thing to try. I took the drive out of the daisy chain and plugged it into the unused firewire port in the computer. I ran the repairs and crossed my fingers, but came up with the same thing
At least I've eliminated one more option. Wish I could mark your reply helpful, but I'm not seeing that option available . . .maybe I've used my "helpfuls" for one day.
Although this is PROBABLY duplicate material on this drive, I'm going to hold out for another day or so in case anybody else comes up with another brilliant idea before I take the plunge and reformat the drive.
Thanks!

WD 3.0 external hard drive won't mount to Mac

I've had this Western Digital 3.0 external for some time and now it won't mount. I'm running Yosemite on my iMac. Full disclosure, I did drop the drive a day before it stopped being recognized on the Mac but it wasn't a hard drop and the external drive was running just fine immediately after the drop. I've seen some posts on here talking about WD external drives not working after updating to Mavericks but I didn't have that problem.
I've zapped the PRAM.
I've made sure it wasn't the cable - I have another 3.0 drive that mounted just fine using that same cable.
This WD external drive is self powered so it's not a power source issue.
I've tried updating the Firmware but since the drive isn't mounting, that did no good.
The USB port on the Mac is fine - plugged in another drive and other devices in that same port and they are all recognized and working fine.
Just to make sure, I tried using another port. No different result.
I tried the Option key on a restart to get to Disk Utilities but it's not seen there.
While the drive was working, I was pulling music from iTunes to my iPhone, just loading it up for a trip. I keep all of my music on this one WD external hard drive. I loaded up about 70 songs and intended to load dozens more. While pulling some songs over, things froze up. Wasn't able to do anything in iTunes or, as best I recall, anywhere else. Things just froze. I hard restarted the Mac - via the power button - and since, the external drive hasn't mounted.
About ready to try this possible solution as described in this discussion:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
Soooooooo . . . help would be appreciated!

Hello
Ihad EXACTLY the same thing happen to my WD hard drive... MINUS the dropping.
Was organising my iTunes and iPhoto library, kept crashing, over and over again, then the last time, i restarted and it won't mount.
Except not only is the WD hard drive not mounting, after the crash and restart of itunes etc neither is my Time Machine hard drive which is connected via a LAN cable.
Exactly the same scenario, all the ports work, all the cables are fine etc.
Just went BOOM - not happy and stopped working.
All my photos and music are on this one drive.
Did you manage to fix your issue?

EZ Quest Firewire 400 ext drive works in 10.4 (PPC) but won't mount in 10.6 (Intel)

I have an EZ Quest external FireWire 400 drive. Was working fine on my MDD Mac running OS X 10.4.11. NOW, when I hook it up to my iMac running OS X 10.6.8, it will not mount. Tried different ports. Tried device on and off at boot. Doesn't show up on desktop or in sidebar of finder window or in System Profiler. Drive powers up, but won't mount. Please help. Thanks. Dennis

I have the same problem. Two different EZQuest Quad interface drives suddenly won't mount on my 2010 iMac (Core Duo) via the firewire 800 or 400 ports. If I use a USB cable, both drives mount as normal, but I need the Firewire 800 ports to stream audio samples for Logic.
Both of these drives were working fine for over a year until I upgraded recently to 10.6.8 on the iMac and then tried to use one of the drives yesterday with a new 2012 MacBook Pro (10.7.4). The drive mounted once on the MacBook Pro, then disappeared and now will not mount on either the MacBook Pro or my iMac.
I tried resetting the PRAM and SMC on the iMac, but the drives still won't mount via firewire. The fact that both EZQuest drives still mount via USB indicates this is a firewire problem particular to Mac OS 10.6.8 and 10.7 rather than an external drive problem. It also seems that many people are experiencing this regardless of the external drive brand. Does anybody know how to fix this?

Connection between the ACR122U card reader and an emulated card is failed

I write a code to connect the ACR122U card reader and a host-based card emulation on my android 4,4 phone that act as a card. When I run a code, I got this error:

what does the "SCARD_E_SHARING_VIOLATION" means?
these are my code line that the error tell:

OK
It's been awile but, I'am sure that we could only
print an index from a card them print photo with that
sys. The G3 was 8.6 upgraded to 9.2 with Photo Shop.
Option was just a thought.

Sorry for answering my own question kinda of. I just got my first IMac 3 weeks ago so I am still learning and exploring how to do stuff on my IMac.
Nope in Windows XP it mounts as a network HD under "my computer" and you can copy files to and from any of the cards in printer card reader. It even shows up fine under paralles as network HD drive letter Z:. Does not matter if the printer is connected via USB or Ethernet.
Btw after my first post I started to play with it. I figure a way to manually mount Hp printer's card readers confirmed to work on 2 different printers models Laserjet 2840 and Photosmart 3310. This trick only seems to work if you have your printer connected via ethernet tho. Goto the "Finder" then "Go" then "Connect to a server" and enter "cifs://IP of your printer" dont enter the quote and replace ip of your printer with the ip address of your printer. Btw you must remove the PW protect from printer for this to work. Not sure why if you have a password why it will not work.
So if this work around works to manually mount the card reader in OS X is their a way to make a script or a short cut for mounting the card reader without going and entering the IP of the printer every time I want to use the card reader?
