Files Copied to USB Drive Disappear

I attached a WD USB drive formatted as FAT32 to my new Airport Extreme but cannot seem to get it to work correctly. I try to copy a file to it, it appears to copy fine (copy finishes, the file shows up in the drive) then a few seconds later the file disappears. I then hooked the drive directly to my Mac and, sure enough, the file is not there. I hooked it back to the AEBS and tried copying a file to it from a PC. Same as before, all appears to go well but the file doesn't actually get copied. Any idea what might cause this and how to fix it?

This morning I was playing around some more and found that some of the files I tried to copy to the drive now show up when the drive is connected to my Mac but are still not visible when connected to the Airport Extreme. I have a different drive that works fine but it is smaller (500GB vs 750GB).

Can't open office files from my usb drive

Dear forum
Sins a few weeks ago i am not able to open office file from my USB-drive.
However i can copy the file to the desktop and than i can open them.
I have this problme only (for as far i know) with office files.
greetings Ypkoba

If the drive is NTFS format, the Mac can read, but not write thiose drives natively.
So the issue may be that the temp file and the output file cannot be created on the same drive.

Cannot emtpy trash containing a file from FAT32 USB drive

Hi
I had copied a .app file from another mac over a network to my FAT32 USB drive. I then deleted the file from the USB drive per normal it went to trash. The problem is that i cannot empty this one file out of trash.
What iv tried thus far:
- I tried restarting.
- I tried dragging it back onto the USB and deleting again.
- I tried dragging it onto my desktop, upon which it asked for my system password, and then deleting again.
- I tried putting it back on the USB drive, restarting in windows XP, and tried deleting in windows.
None of the above has worked. The file is Zero KB. Windows gave an error with something about the file is not completed...?
Thanks in advance
cheers

I am trying to reinstall Windows on my macbook pro. I downloaded the support files and Windows 7 iso file to a USB drive. However, when I try to run the setup.exe program I get the message "this program cannot be run in DOS mode."

I am trying to reinstall Windows (would not launch). I removed the partition and started over. I downloaded the support files and Windows 7 iso file to a USB drive. However, when I try to run the setup.exe program I get the message "this program cannot be run in DOS mode." I was successful before, what am I doing wrong this time?

Try a restart.
If that doesn't fix the problem, shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

Windows 7 64-bit Copying files to external usb drive - files becomes corrupted.

Hi All,
I am getting intermittent problem with regards to copying files to usb external hard drive from my laptop.
When file is copied to external drive, the file becomes corrupt from the external drive.
I have to repeat around 2 to 3 times or more to re-copy the file again until file is not corrupted.
Appreciate of any help.
Below is my system info:

Ok, lets be brief.
This problem is annoying me for years. It is totally reproducible although random. It happens when copying to external drives (mainly USB) when they are configured for "safe removal". I have had issues copying to NTFS and FAT32 partitions. I have
had issues using 4 different computers, from 7 years old to brand new ones, using AMD or intel chipsets and totally different USB controllers, and using many different USB sticks, hard disks, etc. The only common thing in those computers is Windows 7 x64 and
the external drives optimization for "safe removal". Installing Teracopy reduces the chances of data corrpution, but does not eliminate them completely. The only real workaround (tested for 2 years) is activating the write cache in the device manager
properties of the drive. In that way, windows uses the same transfer mechanisms as for the internal drives, and everything is OK.
MICROSOFT guys, there is a BIG BUG in windows 7 x64 external drives data transfer mechanism. There is a bug in the cache handling mechanism of the safe removal function. Nobody hears, I've been years talking about this in forums. It is a very dangerous bug
because it is silent, and many non professional people is experiencing random errors in their backup data. PLEASE, INVESTIGATE THIS. YOU NEED TO FIX SUCH IMPORTANT BUG. IT IS UNBELIEVABLE THAT IT IS STILL THERE SINCE 2009!!!
Hope this helps.

Trouble accessing files on external USB drive after 10.6.8 update

Upgraded to Mac 10.6.8 on my MacBook Pro (I'm not a techie, but the "About This Mac" thingy says 2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3 - I assume that means something to somebody). Since the upgrade, I've been having problems accessing data on an external HD connected via USB - there were no issues before the upgrade, but now it's impossible to even navigate to a particular file or subfolder half the time, as the process freezes 95% of the time (every so often I am able to get through, for no obvious reason) - usually I just get what looks like an empty folder and a little spinning thing in the bottom right-hand corner. Sometimes when I do get to a file - say it's a ZIP file - I'll try to unZIP it and the process will hang; if I try to drag it to the desktop and unZIP it there, I can't get it to copy to the desktop, I just get the "copying files" box and a bar that never shows any progress, it just hangs at zero bytes out of whatever it might be.
Also having intermittent issues with another external USB drive, which is the one I use for Time Machine - about one in every five backup attempts is successful, the rest of the time I get a message saying the backup couldn't be performed.
I have two external FireWire drives as well, and I'm having no trouble with either of those - so I'm assuming the problem is USB-related (and 10.6.8 related, since none of this was happening before the upgrade).
So - I'm wondering if anybody else is having the same issues, and f there's a solution that a non-techie like me could handle that won't make blood come out of my ears.
Cheers!

Thanks baltwo - the PRAM tip was helpful. For some reason I still have trouble accessing a few files, I'm putting that down to them being somehow corrupted. Eric, thanks, but I tried using Disk Utility and the communication problems I was having with the drive meant that the repair couldn't be performed. I may try again now that that side of things seems to be running a little more smoothly. Anyway, thank you both!

Extremely slow file copy from USB 3 external Seagate on MacBook

I copied my iPhoto file of 20GB onto a new Seagate USB external drive from my 2011 MacBook in about 20 minutes over USB 2.0. I am copying up the same file from the same drive on my newer 2012 MacBook pro and it is taking 7 hours. The newer MacBook has a 750GB SATA SSD and is equipped with USB 3.0. Why would it take so much longer to copy from the drive to the newer Mac using a faster USB spec?

Well, I solved this myself with some searching on other threads. I turned off Spotlight indexing on the drive, and killed the copy job, disconnected and reconnected the drive, and the copy is now going quite fast. Will be done in lest than 5 minutes.
System Preferences> Spotlight>Privacy> Press the + and added the external drive.
Apparently, this is the default behavior of Spotlight, and the indexing was causing the bottleneck.

File Labels on USB drive

I have a USB drive attached to my AirPort (3 actually). I use Labels (the colors in the info box) on images and such to aid in ratings & categorization. I've found that I can copy files with Labels applied to the drives and they keep the labels, but I cannot change the labels on files that are already on the drives.
I suspected it was just a caching issue, but I have tried unmounting & remounting the drives to no avail.

Brand new iMacs & an external USB drive disappeared on one of them - help?

I'm new to this particular forum & I just bought a 2.8 GHz intel iMac (my wife is picking up for me this moment) - my boss just bought a 3.06 GHz intel iMac a few days ago, he installed Parallels & then Vista Ultimate w/SP1. He has an external USB hard drive & it showed up mounted on the desktop. When Vista asked him (voices from the dark side) if he wanted to link the drive to Vista he said yes - that's when the drive disappeared & he said that he couldn't get it back & he said that he couldn't find it with the explorer in Vista either. He tried rebooting, tried reconnecting the drive, doing this w/o launching Vista, etc - but he said that it wouldn't come back. He is not experienced with Macs, only the dark side so he's not familar with the system yet. I have not seen his Mac yet. I'm at work, so I do not have access to a Mac, I cannot offer troubleshooting tips for this cold turkey w/o a Mac in front of me, as it has been over 5 years since I've seen a problem like this.
That is why I'm writing this here, because I know that this is no doubt a simple fix for most of you. I can try to get him to come to this discussions site.
I can't wait to fly my new Mac today - should I just go ahead and re-format (low-level) & install from scratch? Even though I've purchased Parallels also, which needs no partition, should I make a partition anyway, incase i want to also use the Boot Camp route on the other partition?
Thanks 1.0E6,
Gino

Success - He finally did get it back after shutting everything down, powering down, pulling its connection, bring the mac back up sans Parallels/Vista, connect up the drive, drive showed back up, then startup Parallels/Vista.
btw - my new iMac is a dream (2.8/500/24") - I changed the memory to 4 mb, low level formatted the Mac, installed the software & "wow-zer" compared to my older lapstand iMac
btw2 - I had posted before to other forums (Airport, Mail), but this was the 1st time to this particular forum (intel iMac)

How to import m4a files in a USB drive and play them using iTune?

I have set the target directory of iTune to that USB drive, iTune just does not play them. The length of the playing is awful long. But in reality , they are merely 1min long reading when I listen to them using Window Media Player.

CS4 is much older than Windows 8. CS4 is meant to work on XP or Vista. Getting it to run on Windows 7 was a bit of an issue, so I'm pleasantly surprised to hear that you have CS4 running on Windows 8 at all.
It's also possible that a new camera records in a codec that such an old version of AE doesn't understand.
Make sure you're running the latest update to your version of AE. You're on version 9, so make sure you've run the Adobe After Effects CS4 9.0.3 Update (I would not suggest updating in the middle of a project though, as any changes might break AE). I would like to reiterate: you're running a version that was released six years ago on an operating system that was released much more recently. So, be careful how you tread. However, if you're not running 9.0.3, you're missing some bug fix updates that might solve your problem.
I would suggest upgrading to a newer version of AE.
That being said, as Dave mentions, CS4 and earlier had lots of trouble with MPEG-4 and other codecs that used interframe compression. Can you open the files in your version of Premiere? If so, you can use Premiere or the Adobe Media Encoder to convert to a proper intermediate codec. MOV is just a container format. QuickTime with the PNG codec will work in After Effects CS4 with no problems as will the other codecs Dave mentions.

Large file copy to iSCSI drive fills all memory until server stalls.

I am having the file copy issues that people have been having with various versions of Server now for years, as can be read in the forums. I am having this issue on Server 2012 Std., using Hyper-V.
When a large file is copied to an iSCSI drive, the file is copied into memory first faster than it can be sent over the network. It fills all available GB of memory until the server, which is a VM host, pretty much stalls and also all the VMs stall. This
continues until the file copy is finished or stopped, then the memory is gradually released as it is taken out of memory as it is sent over the network.
This issue was happening on send and receive. I change the registry setting for Large Cache to disable it, and now I can receive large files from the iSCSI. They now take an additional 1 GB of memory and it sits there until the file copy is finished.
I have tried all the NIC and disk settings as can be found in the forums around the internet that people have posted in regard to this issue.
To describe in a little more detail, when receiving a file from iSCSI, the file copy windows shows a speed of around 60-80 MB / sec, which is wire speed. When sending a file to iSCSI, the file copy window shows a speed of 150 MB/sec, which is actually the
speed at which it is being written to memory. The NIC counter in Task Mgr shows instead the actual network speed which is about half of that. The difference is the rate at which memory fills until it is full.
This also happens when using Window Server Backup. It freezes up the VM Host and Guests while the host backup is running because of this issue. It does cause some software issues.
The problem does not happen inside the Guests. I can transfer files to a different LUN on the same iSCSI, which uses the same NIC as the Host with no issue.
Does anyone know if the fix has been found for this? All forum posts I have found for this have closed with no definite resolution found.
Thanks for you help.

Hi,
Sorry if it causes confusion but "by design" I mean "by design it will use memory for copying files via network".
In Windows 2000/2003, the following keys could help control the memory usage:
LargSystemCache (0 or 1) HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Session Manager\Memory Management
Size (1, 2 or 3) in HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameter
I saw threads mentioned that it will not work in later systems such as Windows 2008 R2.
For Windows 2008 R2 and Windows 2008, there is a service named Microsoft Windows Dynamic Cache Service which addressed this issue:
https://www.microsoft.com/en-us/download/details.aspx?id=9258
However I searched and there is no update version for Windows 2012 and 2012 R2.
I also noticed that the following command could help control the memory usage. With value = 1, NTFS uses the default amount of paged-pool memory:
fsutil behavior set memoryusage 1
You need a reboot after changing the value.

The finder will not show files on my hard drive but will show files on my usb drives

when I click on my Main iMac hard drive the window doesn't open but when I click on my one of my USB drives the widow opens and I can see the files.Any thoughts?
Thanks,
Win

Might try this...
Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop for now...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

How do you recover files on a USB drive?

I used Disk drill to find missing files on my USB, but don't want to pay $89 dollars to recover them. Othe free programs don't even find the files. Is there a trick to recovering them using the iMac?

USB drives disappearing?

Hi. I have a mac Mini that I upgraded a few months ago to Mountain Lion. I've been having problems with USB drives since. I can read them for a few minutes with no problems, but then they suddenly disappear from the Finder and disc utility. I did PMU reset and reinstalled Mountine Lion. No change.
I tried running AHT, but I am unable to access it. Starting up with D key pressed doesn't do anything. Option-D starts up internet version of AHT, but then it says it is not supported on my device. I tried firmware update but that is not supported either. Booting up from the DVD with D key pressed or C key pressed or option key pressed doesn't do anything. Mac starts up as normal. So I am even unable to revert to the previous OS X as mac would not boot from the DVD!
Any ideas as to what the problem may be and how to fix it?
Thanks

My guess is that the USB devices that refuse to stay connected need to draw more power from the Mini than it can provide. This happens frequently on many different macs. The only permanent solution is a powered USB hub. The hub is connected to the Mac with a USB cable, it is plugged into a AC outlet for its power. All yor USB devices are then plugged into the hub.
This one lets you connect 9 devices! Remember that is has to be a powered hub.

Createinstallmedia failes to copy to USB drive

Trying to make USB drive bootable.
Createinstallmedia gives an error that it failed to copy.
Tried two pen drives and same error.
Mavericks is in application folder.
I even tried to copy to different location and tried to make install able from there.
Console logs shows i/o error not sure if it's read error or write error.
One of the pen drive is new so I don't suspect bad drive.
Disk utility shoes no error for MacBook hard drive.
What could be wrong to make USB drive bootable?

Are the USB drives plugged in directly to the Mac? No USB hubs in between?
