USB transfers....

Does OS X support transferring video files from a camcorder to the computer? We bought a hard drive based camcorder and when we went to import the videos we cant see the files on the camera. The camera shows up. The file folder shows up on where its suppose to be located. But I cannot see the file. Its a mini USB connection. I would be pretty ****** if these Panasonic h60p camcorders aren't supported.
Thanks

Yea I just got that from a different site. Kind of a pain. All these camera companies need to make a UNIVERSAL format and not gauge customers.
It's also the customer's responsibility to do some research prior to making an investment.
Searching the following keywords in Google, "SDR-H60 Mac compatibility" revealed the following:
http://tinyurl.com/5lho2j
You'll see a link there to a PDF of the Users Manual (fourth link down). The only thing listed in that manual regarding use with a Macintosh is copying picture files from the SD card via USB. There's nothing mentioned there regarding the transferring of video files. If the manufacturer doesn't list video transferring as a supported function in its own user manual, then I would find it difficult to put the blame on them for the lack of that function. This search took about 10 minutes.

USB transfers cached: No ETA

USB transfers have the very annoying problem that they claim "100% done" even though it will still go on for 15 minutes or more (if a lot of data is being moved around), leaving you in the dark about the REAL time the transfer will take, and only displaying some random fake values instead.
Is there a way to fix that so that USB file transfers actually display the correctly estimated time till completion, instead of having you stare on the screen indefinitely without any idea how long it's gonna take?

Thanks, I tried that but it gave
mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error
and dmesg said
EXT4-fs (sdb2): Unrecognized mount option "flush" or missing value
It seems the flush option is only available for FAT filesystems.

USB transfers stop after ~400 MB

I have a Mac Mini I use as a home theater computer. Connected to it are 3 separate RAID sets (Set1, Set2, and Set3). All 3 sets are mirrored (RAID1), so there are 6 total hard drives -- Set1 is composed of 2x 2TB Hitachi HDDs, Set2 is 2x 2TB Seagates, and Set3 is 2x 3TB Western Digitals. Set1 and Set2 are housed in a Mediasonic ProBox 4-bay enclosure (USB 2.0 only), while Set3 is housed in a 2-bay Aukey enclosure (USB 3.0). All RAID sets were set up via Disk Utility, so all are formatted as Mac OS Journaled. Set1 and Set2 have been set up for about 5 years, while Set3 is relatively new. Everything is connected to the Mac via USB. I'm running the latest release of Yosemite (not Beta).
So now for the problem. When I try to copy files from Set1 to anything else (Mac Mini desktop, Set2, Set3, flash drive, etc.), the transfer essentially stops at about 400 MB into the job. The Finder transfer window doesn't close or crash, but it just seems frozen. The estimated time skyrockets. I'm able to push the X button to stop the transfer. The transfer rate when this happens isn't zero, but it might as well be -- it's like 1 MB per minute.
Weird thing is, I can copy files to Set1, just not from it. I've tried doing it with my Macbook Pro and i have the same problem, so it doesn't seem to be the computer. I can copy files from Set2 just fine (which is in the same HD enclosure), so it doesn't seem to be the enclosure. I've even tried physically swapping Set1 and Set2 to see if the bay connections were bad, but data transfers still slow to crawl at around 400 MB. I've tried different sized files, different types of files, restarting the computers and enclosures, rechecking connections... everything. I'm thoroughly stumped. Please help!

I've just replaced the MB, CPU, RAM sticks, video card and PSU after the previous MB died on me last week. The problem I've been having is that my mouse and keyboard (they're both USB) stop working as soon as Windows starts loading. They're both functioning during the boot sequence. USB controllers and USB Legacy Support are both enabled in BIOS. I've tried plugging in my old ps/2 keyboard but that one won't work either once Windows has started loading (although it just struck me that it's possible I accidentally plugged it into the mouse port). Any advice on how to resolve this issue would be greatly appreciated.
Was old mainboard that "died" on you same as the new mainboard?

Super slow usb transfers on non-unibody mac book pro after sl upgrade

Anyone other experienced the slow usb transfer speeds on thier non unibody macbook pro (late 2008) after updating to snow leopard.
I have done some testing using a sandisk cruzer 16gb on my non unibody macbook pro and there are transfer speeds super slow on the other hand with the exactly the same usb drive on my unibody I get the transfer speeds I expect.
Is there anything to do? I've tried SMC & PRAM resets without any difference.

N8 USB file transfers slow

It was fast at first, now we are barely pushing dialup modem speeds.
I know it's not my computer because all other USB transfers are ultra fast, it's just this phone that now transfers slow.

> Transferring smaller blocks of data is a not solution and not dealing with the problem.
It DOES work anyway. Just try, clever guy.
The problem is caused by overflowing data buffers; so sending smaller blocks is the only solution at present; if you like it or not.

IMac FireWire port used for USB device

I have a 27" iMac which of course has a FireWire port, but I don't own any external FireWire devices. I'd like to put that empty port to use as a USB port to connect an external storage device. Is there a cable, converter, or adapter made to do that?

Common user always looks at the bottom line price on computer peripherals and USB devices are always cheaper. USB 2.0, in theory, should be faster than FireWire 400, but they usually aren't because of the way USB transfers data in short bursts or packets of data. FireWire 400 and 800 drives are faster as they transmit data in a more continuous, constant and reliable stream of data.
This is why devices that use FireWire or have both USB and FireWire connections are always more expensive.
So, those users never use the FireWire port.
FireWire is faster for external hard drives, especially data transfers and for booting and running a Mac from an external FireWire drive. FireWire optical drives are faster. FireWire audio devices and interface devices are even faster and more reliable than USB.
FireWire is more expensive, but more reliable data transfer protocol.
There is no way to bridge the two device protocols . It's either one or the other. The masses always choose the cheaper USB devices.
The masses don't care about faster and consistent data transfer rates or better reliability.
Especially if a user isn't some sort of creative like a graphics, designer, Illustrator, photographer, digital painer/3D-CGI Artist, engineer, audio or video/multimedia professional.

CA-126, Nokia 5800 Music, Unknown USB device

I've got a CA-126 so I can do both USB transfers and charge my 5800 but Windows only seems to recognise the device periodically.
Can any knowledgable soul with a working CA-126 please look at "Computer Management" and send me the USB device ID please so I can check mine is the same?
Or give me some hints as to why I'm seeing these problems?
Thanks,

USB Hard Disk Question (Format Type)

Hi,
I've bought a 500GB Hard Disk which I'd like to use for editing.
The Hard Disk works fine and I can Log and Transfer small video files ok. The problem occurs when I want to capture large video files. These always seem to error. The same large video files work fine if I capture straight to my iMac's internal Hard Disk.
I think the problem occurs when the video is greater than 4GB. Could this be related to the Format type of the USB Hard Disk?
If so how should I re-format the drive to work with large video files? And how do I do this on a Mac?
Thanks,
Richard.

A USB drive will not cut it for video editing. You will get dropped frames, either when editing or capturing to it. USB transfers data in bursts, not a continuous stream as FireWire does. Wile it might not be happening right now, it will once you start filling it up, having multiple tracks in FCP, etc.
Your drive came preformatted for Windows, as do most of them. The FAT file structure used has an individual file size limit of 4GB.
To reformat as for the Mac OS, use Disk Utility (In the Applications/Utilities folder).
Open Disk Utility.
Select the drive in the column at left.
Click on Erase and choose Mac OS Extended, click the Erase button at bottom right to confirm.
This will of course, destroy all files currently on the drive. Back up first!
For best results, recapture your video again.

USB hard drive transfer forces system into a cawl

I attached an external USB 2.0 hdd and stored data on it at a rate of about 35MB/s. This took really long, cause it was a larger backup. CPU load didn't exceed 20%.
However, the whole system suddenly because slow to react and there were really bad freeze spikes coming up repeatedly that would completely freeze the system for like 10 seconds or so.
Basically the system because very hard to use, and that over the course of some hours till the backup was finished.
It's a Core i7 with 8 GB RAM of which about 6GB were free.
Now I think that must be a bug in the kernel, since a mere USB 2.0 transfer shouldn't be able to freeze this kind of system?
I tried a workaround by specifying
ionice -c 3 -p <pid of the copy process>
but although to me it seemed that the general system slowdown disappeared, the frequent freezes remained.
Are there maybe any unofficial kernel patches available for USB transfers that would prevent the system from freezing? Any other solution?

It's a known issue and it has been present since forever.
What filesystems, what schedulers, are you using the stock Arch kernel? Does it happen with the -ck kernel?
What command did you use exactly to move your data?
I write into a truecrypt container that's on an NTFS-formatted USB stick and contains an Ext4 file system.
I used two commands, both cause these problems, the first one being even worse than the second one.
truecrypt -t -c <..create encrypted container file..>
dd if=/dev/sda of=/<..truecrypt container mount point> bs=1M
No idea what schedulers, how do I find out?
Stock kernel yes, except I had to patch it with:
CONFIG_HZ_1000=y
CONFIG_HZ=1000
which I needed for my NVidia GPU to prevent it from crashing randomly when Bumblee daemon tries to enable it and enter an unusable state until system gets rebooted.
This goes with kernel parameters:
rcutree.rcu_idle_gp_delay=1 acpi_enforce_resources=lax
I haven't tried that "ck" kernel because I read how people reported that it didn't help them with this problem.

External HDs: Firewire + USB

I'm the owner of a 1GHz eMac with only FW + USB1 ports and have successfully daisy-chained 2 FW drives to it, occupying only 1 FW port with decent transfer rates. Recently someone gave me a USB2 drive and I've noticed it is the slowest thing on earth, plugging into a USB1 port of course. But I've also noticed a USB2 port on the back of one of my FW drives. Could I chain the USB2 drive to my FW drive instead of the USB1 port on the eMac? Would I get better transfer rates this way?

moyboy,
Welcome to the Apple Discussions!
Were you to attach the USB 2.0 drive to the Firewire/USB drive, the USB 2.0 drive will remain invisible to the computer. The USB port on the back of the external drive with both USB and Firewire is for connecting the drive to a USB port on a computer (not at the same time the drive is connected via Firewire!). The Firewire and USB ports don't communicate with each other. If you daisy-chained the USB drive to the external drive's USB port with the second drive being attached to the Mac via Firewire, there'd be no communication between the first drive and the computer.
If it were possible to daisy-chain a USB 2.0 device to the USB port on a multiple-interface external drive, every owner of a USB 1.1 Mac who wanted to be able to use a 5th Generation iPod or iPod Nano would be snapping up those external drives. Put it this way, if you can attach the USB 2.0 drive to the dual interface drive and actually have it work at USB 2.0 speeds, let me know what model drive you have and I'll rush out and grab one myself!
USB 2.0 nominally allows transfers up to 480 kbps while USB 1.1 is only rated at 12 kbps, which accounts for the abysamal performance hit. Firewire 400 is rated at 400 kbps but is in practice faster than USB 2.0 since USB transfers are done entirely under control of the computer's CPU while control of Firewire transfers is off-loaded onto Firewire hardware.

Speaker Sets & MP3 Players & USB

Is there a Creative Speaker system that will accept the USB output from my Creative Zen Xtra directly, without having to go through my PC?
I know I could just plug in the headphone output on the Xtra to an analogue stereo input on my Soundworks DTT3500 Digital. But I'm looking for a USB digital input, if such a thing exists.
I'm considering an upgrade, as my old DTT3500 is becoming a little unreliable.
Cheers,
RobAnt

does not exist.
simply because you need a somewhat complicated software routine set up to do the USB transfer, and the Xtra, as will all MP3 players, will only work as a client, meaning that during USB transfers the computer does all the thinking.
To send the signal directly would mean the MP3 should be able to do the thinking, and the capacity of the CPU in the player is far from high enough for that
(if it could do that, nothing would prevent them from doing visual EQ's e.g. as well)

6790 USB transfer without the screen

Hi,
My nokia 6790's screen died a few months ago and I had to change my phone. I now have a Nokia E63 and would like to take the contacts out of my 6790 and in my E63.
The problem is that since I no longer have the screen, I can't go in the menu and set the phone to make USB transfers. If anyone had pictures / indications on the menus so that I could do it without the screen, it would help me a lot.
Thanks

Not sure if this works but no harm trying..
As soon as you connect the phone to PC thru' USB.. Press the Centre of the Navigation Key ( ..as if you are selecting some option that is highlighted on the screen..) .. see if the OVI Suite is recognising your phone...

ITunes shows 2,700 photos on my iPhone, but there's only 161 on the phone.

My iPhone's disc space is suddenly full. iTunes shows I have 7gb of photos (2,700)on my iPhone when I connect it, but my phone really only has 161.
I recently updated to iOS 4.0.1 on iPhone 3GS and iTunes 9.2.0.61 on Windows Vista. I was previously using iOS 3.1.3 and iTunes 9.0.xxx (not sure of which 9.0 version) and I had been using an App called Goodreader. I would transfer my files via USB with an .exe file called GoodreaderUSB to my iPhone. Now I can't since iTunes has been cracking down on that, and Goodreader uses iTunes to USB transfer with their new version and iTunes 9.2.xxx. I have a feeling my old USB transfers are all still in my phone, just unaccessible but iTunes is showing them as photos as far as disc space goes. This could be completely unrelated to Goodreader, but I have a strong suspicion it's the problem.
I've attempted multiple backups and syncs and I'm only syncing 84 photos (part of the 161 on my phone).
I also just realized it's showing 5.8gb of apps, when I did the math quick and only have 2gb of apps.
My iPhone also shows that I have used this much disc space when I run the app "System Activity Monitor."
Anyone know how to resolve this problem?

GoodReaderUSB originally worked by transferring files to a special location on a user’s iPhone, which iPhone’s GoodReader app was able to access. However, accessing this location was a violation of Apple’s iPhone SDK Agreement, because the app had to access files outside its own private storage space, which is forbidden by Apple.
Because of this, your only choice to fix this. at this point, may be to restore your phone as a "new" device in itunes and NOT from backup. Follow this by syncing your content back to your phone. Unfortunately, ALL saved data on your phone will be lost.

Saving iMovie 4 projects on an external hard drive

I'm starting the ambitious project of copying our family videos from 8mm tapes to iMovie to eventually making DVDs. since I don't have much disk space on my iBook, my plan is to put the iMovie files on an external hard drive & work from there. Here are the system specs:
Camera: Sony DCR-TRV520 (Digital 8)
Computer: iBook 800 MHz PowerPC G3, 28GB hard drive, 5GB available
OS 10.3.9
iMovie 4
Hard Drive: LaCie Eternet Disk mini 300GB (150GB available) format: Mac OS Extended
Problem: Open a new iMovie project on the external hard drive. Start to import the footage. After one or 2 seconds, the image freezes and import aborts.
Solution: Open a new project on the computer. Footage imports fine.
Problem: Can only import 1/2 hour or so of video before I'm in trouble. Files WAY too big for my itty bitty iBook!
Solution: Make a new iMovie file on the external hard drive & copy the clips from the computer to the hard drive. (this takes TONS of time!)
Problem: Open movie file on the LaCie. Import the clips. Clips show up but won't play!
Question: Is there any better way to do this? Why won't the project work on the external hard drive?
I teach video production at a high school and have done this many times on newer iMacs (iLife 6). We can't save every project on the computers, so certain projects I'll copy to an external hard drive. I've never had a problem working on an iMovie project from the hard drive. I considered uploading my movies on the computers at school, however then I'm stuck with iMovie 6 files on the hard drive and iMovie 4 at home.
Any suggestions -- other than get a newer computer?

Importing new footage from a video camera and working with iMovie with footage already on the computer are two completely different things.
At school, do you actually IMPORT video from digital camcorders directly to the USB drive as you said you were doing at home?
Because while you can indeed work on iMovie projects off a USB drive if you are not actually importing video, the whole importing process from a Firewire camcorder is sort of a streaming video type transfer and Firewire is used because it has a mode for this type of transfer. USB, on the other hand, can not import video from a camcorder straight to a USB drive reliably because there is way too much CPU overhead associated with USB transfers and it therefore can not keep up with the "streaming" video coming out of the camcorder.
If you want to find out more details, do a search for "isochronous" with Firewire. Firewire uses type types of transfers. Asynchronous transfer which is like USB uses where you transfer data, wait for the CPU to respond, then transfer the next chunk of data. Video transfer uses and isochronous process where, to put it very simply, the camcorder starts spitting out chunks of footage with a checksum and the receiving end receives it, calculates a checksum and if the checksums match, stores the chunk of data. If they don't match, the data is discarded and it starts to receive the next chunk of data. There is no ability to resend failed data so you get dropped frames in your footage.
If you import via Firewire from Camcorder to Mac then directly to an external USB drive, the transfer from Mac to USB drive will be too slow as the CPU and drive have to start doing their "did you get it?", "Ya I got it, send another/No, send again please", "OK here it comes" routine while in the meantime the camcorder to Mac Firewire transfer is just pumping out data at a fixed rate. Once the USB connection falls behind the process aborts.

Still: Macbook Air 2013 Wifi Issues On Wake-Up (And Partial Solution)

I just got my new MBA 13" Mid 2013 last week (updated to Mavericks), and have been having issues with the wifi for a couple days now. Specifically, when I wake my MBA in the morning, it will have disconnected from my home wifi and will not reconnect again. It can see the wifi (and it did ask the WPA2 password after I deleted the network in preferences), but it will not connect due to a "Connection timeout".
I didn't have these issues with my old MBP 13' Early 2011 (also running Mavericks). Also, this only started after I had fully set up my MBA and replaced my MBP, that is, connected it to the external display, hard drive, etc.
Now, it turns out what I have to do is disconnect my external hard drive and reconnect to the network. What kind of architecture makes something like this even possible? And it's not just me, https://discussions.apple.com/message/23423481#23423481 had the same problem: needing to remove a USB device in order to be able to reconnect to his wifi.
This reminds me that with my old MBP, I had an issue where copying large data volumes to external drives via USB would render the wifi connection unusable. So apparently there is something about Macbook architecture that links USB and wifi.
But why does this only occur after a full night of the MBA sleeping? I guess it would have to drop the wifi for energy saving, which it doesn't do right away whenever it goes to sleep?
In any way, this is extremely frustrating. What is the deal with USB and wifi in Macbooks? I really hope Apple can fix this via a software solution, but to be honest, I don't trust them to anymore. I guess for them this is "working as intended".
Cheers
Nate
PS: Please, do not post any links to "troubleshooting steps I may find helpful". I do not, because they were not.

It turns out the MBA doesn't even have to go to sleep for this to happen.
Today i received a new HDD for my time machine backups, so some data transfer was necessary. I made a 600GB backup from my Mac and an external hdd I use for media files, then i started copying another 500 Gb from one external drive to another (USB to USB).
Now in the middle of this transfer (which is rather slow to begin with at around 46 MB/s) my wifi connection just went out. My iPhone, iPad and Windows PC can still connect to my router, but the Mac tells me to "move closer" to it.
It's interesting that my Mac can no longer see any other wifis besides my own, so I guess it's wifi range is somehow impeded by these USB transfers? How does that even work?
At around 50% the data transfer had come to a complete halt, so I interrupted the process. Two seconds after I had ejected AND unplugged both external drives, the MBA could "see again". All visible wifis were listed again and I could connect without problem.
Is there anyone with a similar experience? Is this a hardware defect or an architectural problem? Why have I had these USB/wifi-issues on two Macbook models spaced lmost three years apart?
