Hidden files on USB and memory cards

When I put my USB or my camera's memory card into my mac and delete files from them, they disappear but haven't actually gone from my memory card/usb. So the space is still taken up by the hidden files. On a PC I can find how to reveal the hidden files and delete them, but I don't know how to do this on a mac.

Don't delete files from your camera cards using your Mac — always erase or format the cards in the camera, using its own menu commands.
What sort of device do you mean by "my USB"?
After trashing any file(s) from any device that is connected to the Mac, you must empty the Trash to regain the space occupied by the file(s). The device must be connected to the Mac when you empty the Trash, because the Trash is an invisible folder that resides on the device, and it can't be emptied if the Mac can't access it.
The reason I recommend not trashing files from your camera cards while they're connected to the Mac is that many cameras become confused when they encounter a Mac Trash folder on a memory card, and will refuse to use the card until it is reformatted in the camera.

USB and memory card??

I have a bell phone that takes a flash 512 memory card I can take pic and put mp3 on it. However the card is full and whenever I put it in my computer it just askes me to open my disc utilities and it says ( A disk attempting to mount as Unknown has failed verification or has failed to mount. Please use disc utility to check the disk and correct any errors. ).. I have tryed everything and nothing seems to work? It use to work fine as it would open I photo but now I cant do a thing.
And I am not sure if its the phones fault, the flash, usb or mac??
Any help would be great.

Hi Geordin,
Did you buy the card from Bell? or did you buy it from eBay? There are a large number of fake flash memory cards around, which will report as being 512MB (or 1GB, 2GB) but in fact only be 128MB or smaller. This may cause the problems you are reporting.
I would suggest trying an application like PhotoRescue : http://www.datarescue.com/photorescue/ to see if you can recover the photos, then format the card in the phone, and try reading from it again. If the capacity changes, or it doesn't work, I'd get a new card from a reputable reseller.

USB ports and memory card slots not working

My Pavilion a6120n desktop has worked brilliantly ever since I purchased it. As of last week the 2 usb ports in the front and the 2 unused usb ports in the back have stopped working. My printer is plugged into one rear port and my wireless mouse is plugged into a second rear port and these work fine. I generally use a memory stick for data swapping or the card reader slots (which have also stopped working). I no longer see the memory card icons in the "Computer" window. When installing something new the "New Hardware Found" statement pops up but the driver install always fails. I think it is a software issue but there are no usb drivers to download on the HP/support site that I can find. . . so . . . Below is what I have tried so far.Run antivirus software. Full scan & memory scan - no issuesRun malewarebytes full scan - no issues I have tried restarting several times with no success. Restore to several previous restore points = failedRestarting computer in repair mode = failedRun the repair disk that I had made = failedChecked the power management for each usb port to see if the power was routed properly = okRemoved the case cover and carefully inspected the wiring and connectors.finally I tried uninstalling the usb drivers = failed Upon restarting the computer the last time the startup file must have failed and after several hours of attempting a repair I had to reinstall the Window 7 completely. Still no usb or memory card function. Any help would be appreciated Thanks,MrBob38

After I import a movie file from the camera memory card, Imovie 10.0.1 acts as if the memory card is empty though I know it isn't.... I can't import that file to iMovie again.. is that the way it worksnow? Thank you, Filippo

On IMac 10.9 After I import a movie file from the camera memory card to Imovie 10.0.1 it acts as if the memory card is empty though I know it isn't.... I can't import that file to iMovie again.. is that the way it works now? Anyone know? Thanks, Filippo

I would like to know this too. I imported a lot of files, then Imovie crashed. I went back in and they are not in imovie at all.
I reconnected the camcorder to import again and though they are still on the camcorder, I no longer see them in the available list of files to import. I'm sure there is some sort of simple setting somewhere that reveals all files even if it thinks they are imported.
Thanks

Toshiba 40SL733g - How to play video files from USB flash memory

When I plug my USB flash memory in USB port, Media Player menu shows up with two options : Photos and Settings.
How do I make my TV recognize and play video files from USB flash memory?
Flash is on FAT32.
I have tried to play avi, mp4 and mkv files but nothing happens. It looks like flash is empty.
Could you please help me solve this problem.
Thanks!

bzunic, have you updated the firmware for your model?.
With my own set, (32RL900A), the instruction manual said that certain buttons on the remote control were "unused", however, after the first firmware update, the previously "unused" buttons were used, (In our case, Time Shift, Record, and so on).
The reason I talk about this is, these features became available after a firmware upgrade, and were not mentioned in the user manual, in our case, and a later download of the instruction manual for our model actually gave the instructions for the use of these features, which were shown as "not available", in the original instruction manual supplied with the TV, but became available after the firmware upgrade.
Let us know how it all works out ............

Save an image file in my phone/ memory-card memory.

Hi everyone,
I want to save a file (an image file) in my phone/ memory-card memory.
i've infact captured it from camera and now want to save in the memory not in the RecordStore.
What should i do ?
Please help me.
Thanks in advance

hi,
You will need the pda optional package jsr75 for file connection. Then create a byte vector from the image and then write the bytes to the location
byte[] bytes = ... // from input stream
String filePath = "file:///c:/"+aFileName;
          System.out.println(filePath);
          OutputStream os = null;
          FileConnection fc = null;
          try {
               fc = (FileConnection)Connector.open(filePath);
               if(!fc.exists()){
                    fc.create();
               os = fc.openOutputStream();
               for(int i = 0;i< bytes.length;i++){
                    os.write(bytes);
          } catch (IOException e) {
               throw new IOException();
          }finally{
               if(os != null)
                    os.close();
               if(fc != null)
                    fc.close();

Booting from USB Flash Memory Card Reader on RS480M2-IL (Test Results)

I just completed testing my USB Flash Memory Card Reader (see profile) as a boot device and wanted to provide feedback to the Forum.
A UBS Flash card will show-up on the Advanced Bios Features menu, Hard Disk Boot Priority list, when a Flash card is physically present in a card slot. It showed as "USB-HDD0 : AFT PRO -8MX CF 0" with a 256MB Compact Flash (CF) card for my test. Using the enter key on the Hard Disk Boot Priority list allows for ordering priority, which was necessary to place the CF Drive before my real Hard Drive for the card to boot. When the card is removed, it drops from the list.
I initialized my CF card as a DOS system disk using HP's USB Disk Storage Format Tool v2.0.6 for the test.
Since it is recognized as a Hard Drive, it boots as the C: drive, not A/B Floppy alternative.
I also ran a quick test to see if XP Pro Setup would see the drive. It does show as my D: drive partitioned FAT. Too small (256MB) obviously for XP Pro install, but it does present opportunity for larger size flash modules. My Flash Reader actually has 4 different disk functions/slot groups, so XP Setup acknowledge the presents of those empty three slot groups as "Unknown Disk" on the drive list.
I hope the information is useful for anyone planning a build or looking for alternative boot methodolgy with the board.
This board just gets better and better.

So with a nice size flash memory u could start your box with a key drive and lock up your computer when you leave it unattended.

I can't open pages files from USB and iCloud due to : "The necessary file index.xml is missing".

I can't open pages files from USB and iCloud due to : "The necessary file index.xml is missing". Original file is written on iMac (2014) and saved to an USB stick and then transferred till macBook Pro (2009, Yosemite) for editing. Then I shared the files by iCloud but I am not able to open them on iMac again. Niether can I use the USB stick to transfer the edited files back. I'm running Pages '09 4,1 (923) on the macBook and Pges 5.5.2 (2120) on the iMac.
Håkan

Pages 5.5.2 is extremely incompatible with even other Macs let alone the vast majority of PC and MsWord users out there, so not a good idea to leap into the fire with both eyes shut.
After having done that to the first Pages 5 files, Apple has repeatedly done it to even the most minor point updates. Apple can't even anticipate its own erratic changes let alone what everyone else needs doing.

Is there a program I can use to retrieve corrupted .MOV files, from a HD memory card where some files will open, and others wont?

Hi,
I have a Mac OS X version 10.6.8 with a 3.06 GHz Intel Core 2 Duo processor and 4 GB 1067 MHz DDR3 memory.
I have recently shot some still and moving footage on my Cannon EOS 500 D (digital camera) using an AMICOE SD C10 8 GB high speed memory card.
After uploading these photos and movies onto my Mac, I am only able to open about 2/3 of the files that appear on the screen. In the case of the movie files, I can see a number of the file icons, however about 1/3 of them will not open (I get a message saying that Quicktime does not recognise this file - yet it is a .MOV file. Interestingly I can see a small thumbnail for each of these files that will not open, however I am unable to expand the thumbnail into the larger size) and there are a number of photos that simply do not appear as a file or thumbnail.
Is there a program I can use to retrieve these corrupted .MOV and JPEG files from either my computer or the memory card?
Thank you for your interest in this question.
Cheers,
Shaughno.

....to add to the last part... When adding to the iTunes library,- I need iTunes to make a quick-scan to verify that media I am adding isn't already in there,- preventing duplicates that make remedial tasks of removing* duplicates so annoying and unproductive...

Music Files and Memory Card On N97 mini

I,ve own my N97 mini for about a month now, been serving me well except for this problem...
I created a folder on the E:/ drive for storing musics I transfered via PC Siute but I noticed that I can't seem to find the onces I trasfered via Bluetooth. When I open the music player and refresh, it seems some of the musics are not added to it. When I open the folder I created for musics I see the songs there but when I go back to the music player it ain't there.
What can be done?
I added an 8G memory card to my phone and it's been misbehaving. Problems ranging from slow boot up and opening of applications to this error NOT ENOUGH MEMORY PLEASE DELETE SOME DATA whenever I try to open the music player. I understand that N97 mini can take upto 16G memory card but how come 8G gives it problems?

Why on EARTH are you transferring music by Bluetooth ??? Simply connect the phone to your computer by usb cable in Mass Media mode. The phone will show in 'My Computer' as an external hard drive E. Open it and your music folder will be there. Then drag and drop any music you want FROM your computer TO the 'Music' folder on your phone, safely disconnect the phone from computer, go to music player and refresh music, that's all there is to it !!

USB cameras and memory cards slow to be recognized? Simple solution!

For some users, Image Capture is slow to recognize memory cards and cameras connected to their Mac. However, there is a quick and easy solution.
Bluetooth devices seem to keep Image Capture from accessing memory cards and cameras plugged into your Mac.
To alleviate the problem, navigate to System Preferences, click Bluetooth, and select and delete the devices you no longer need. With no Bluetooth phones connected, Image Capture works at a normal speed.

First make sure that no application is using or has open any files on the disk. Then:
Click and drag the disk icon on the desktop to the trash. Wait for the system to recognize the action, and the icon should disappear from the desktop. It is then safe to remove the device.
Alternatively, you can secondary click on the disk icon, and then primary click "Eject (name of disk)". Wait for the icon to disappear off the desktop, and then it is safe to remove the drive.
Here is a detailed help document on the subject.

N97 Memory in use and memory card not present issu...

Hello,
I bought my Nokia N97 2 weeks ago from your website. I switched my old phone data over to the new one, transfer few document, music onto the new phone from my PC and updated software last week. It worked for up until now but yesterday I all of a sudden
- while I was playing music got a message saying files have been corrupted, it stopped playing music and deleted all documents from the E drive.
- I went into the file manager but I could not access my E: Mass Storage drive anymore (from file manager) as it says 'memory in use'.
- I connected the phone through USB cable to my PC, select PC suite on my phone but I got a message on the phone screen which said "Memory card not present (USB card may not work as expected)"even though I used it last week. However, while USB is connected, I could see the 'Phone Browser' on my explorer on my PC but no mass storage
- I have restarted several times, took the battery in and out and tried but no luck.
- I did a hard reset on the phone (*#7370#), it reset everything but no luck on the E: Mass Storage as it still says 'memory not in use'
- I tried software update, it refreshes the list and does not update anything when I click on it.
- I went to Nokia Care Centre and they failed to fix the issue (after doing a reboot) and asked me to send the faulty phone back.
I bought the phone from mobilephonesdirect.co.uk - when I called them, they were quite hostile and asked me to email ([email protected]). I emailed but the response time is apparently 5 days. The guy on the phone tells me since the phone is 7 days older they cannot replace it. I called the insurance guys, they said because it is a manufacturer issue its not covered by the insurance. I called the repair centre recommended by mobilephonesdirect, they said if nokia care centre cannot repair it, there is no point in sending in the phone.
Now what do I do? Does anyone know how to fix this "memory not present" issue?

Hi mate, Not sure how to fix the problem ,but you have the right for this to be sorted.
I take it you bought it from a website or over phone,this is classed as distance selling, That means you are entitled to 7 days "cooling off period" in which you can return the product no questions asked. I think this is where they are getting there 7 days from. It has nothing to do with faulty goods. If the goods are faulty it breached the "Sales of Goods act 1979" as the goods should be fit for purpose which yours is not.
The Sale of Goods Act makes reference to ‘the seller’, this is the shop, the retailer, or the individual you bought it from, and is who you made the contract with. It is not the manufacturer, and don’t let the shop tell you otherwise! If there is an obvious fault with the item at any time within the first 6 months and it has not been caused by wear and tear or misuse, your first port of call must be the shop you bought it from. They have the responsibility to put the matter right, and should not evade this responsibility by referring you to the manufacturer in the context of a guarantee or warranty. Even after this 6 month period, if the item breaks down prematurely , you should always go back to the shop or retailer in the first instance.
Your statutory rights under the Sale of Goods Act take precedence over and above any warranty or guarantee you may have with either the retailer or manufacturer. It is misleading for a shop to tell you they can do nothing simply because their warranty or guarantee has run out, because you will still have your statutory rights.
I have an n97 and my key lock slider just came off. I had to argue untill I was blue in the face that it is a fault and not over use (its the most pressed key on the phone) Finally they sent it off for repair for me.
Hope all this helps a little. There is more info on many websites on Sales of goods act which may also help you.
Regards
Jesta

Files not showing on Memory card N73

Nokia N73, Memory card is Mini SD
my phone said 'memory full delete some data' ever since I can no longer see 95% of my files on the memory card. I have hooked the phone upto a laptop and also used a memory card reader but still my memory card is now only showing a handfull of files.
The thing is that in properties it stil shows 1.9GB used of 2.0GB but only displaying about 50 MB of files.
I had about 500 files of which it shows about 15.
Can you help?

your memory card must have some problems. try to format or insert any other memory card and check it, If the problem still there try to format your phone memory by dialing *#7370#.

Lost videos after pushing "command z" and memory card already removed.

I recently copied some videos from an SD Card using the built in card reader on my 2009 iMac. After copying the videos to a folder on the computer, I removed the memory card and formated/erased it in the camera. Upon returning to my computer (memory card still removed) I accidently pressed "command z" with the current Finder window still active and the videos disapeared. I was wondering if the videos are lost forever, or is there some location that they could still be found at? Thanks
