Capture Problem (av-1) - Mac OS Extended formatted drives

I've got a bit of a stumper. I've been trying to capture some video. (I'm backing up all my Hi8 tapes to DVD.) I have no size limit enabled. The time limit is set to 30 minutes. When I finish, FCP stop the capture and creates the capture files. I have one 4.1GB file (Untitled) with the movie and sound and another 780MB file (Untitled-av-1) which is not playable. The movie file plays with quick time and is able to be edited with FCP. But, the other file does nothing. If I delete the second file, the first movie becomes unplayable and uneditable in FCP.
I searched this issue. I do not have Norton AV or any virus protection software. All my drives are formatted MacOS extended.
I don't know why else this extra file is there? Anybody know? I've captured files before and this did not happen. Strangely it's happening now.

Well, you did mention...
so I don't understand why it's (apparently) running into a problem peculiar to FAT32-formatted drives
I kind of had to assume at that point the source drive was the one you formatted as Mac OS Extended two years ago, and the target drive was FAT32. If not, then I'm not sure why you mentioned FAT32 at all.
In that same thinking, error code 0 is directly related to FAT formatted drives.

Error code 0 when copying a large file to a Mac OS Extended formatted drive

I always back up my photos manually by dragging a folder containing many folders containing many photos into an external drive that I immediately formatted as Mac OS Extended (Journaled) the day I bought it 2 years ago. I now run into a Error Code 0 when I do this. The "mother" folder is 240 GB in size. As I stated, this drive has been formatted for the Mac, so I don't understand why it's (apparently) running into a problem peculiar to FAT32-formatted drives. My iMac has 16 GB of RAM, of which 10 GB was free, the last time I tried to do this.

HT1604 Is there any difference between Mac OS Extended Format and ExFat?

Is there any difference between Mac OS Extended Format and ExFat? I read in a blog that the ExFat was a good way to format an external drive because it avoided many of the pitfalls of the other formats, as long as it is supported by the operating system. I tried to format my new Seagate drive, and got an invalid option error. I was able to format it in Mac OS Extended format. Can you please tell me if this is similar to ExFat. Thanks.

The Mac OS format can only be natively read to and written to by a computer running the Mac OS. This creates a problem if the user wishes his external, or other drive to have seamless compatibility between two different OS's, such as Windows and Mac. Yes, there are software solutions that enable a Windows PC to work with a drive formatted as Mac OS, but it gets complicated if you wish that drive to have compatibility "on the fly" with any PC you may encounter.
It turns out that the format known as ExFAT is able to be natively read by both a Mac and a PC, without running any additional drivers on either machine. ExFAT also doesn't have some of the limitations of FAT32, which both OS's will also read/write.
ExFAt is not perfect though. Formatting the drive as Mac OS Extended has some advantages on a Mac. First, it is the only format that permits all functionality of the Mac OS, such as using the drive for Time Machine.
ExFAt is often thought of as the best middleground for an external partition/drive that needs to have easy cross platform compatibility between a Mac and PC running Vista or Windows 7.

I have an iMac OS 10.7.5 I have been sent a disc using Mac OS extended format which I am unable to open. Any suggestions?

I am using an iMac OS10.7.5 I have been sent a disc using Mac OS extended format but I cannot open it. Any suggestions. I have also tried on my laptop (10.5.8) similarly without success

The disc appears to b an ordinary CD and it contains the text of a manual which comes quarterly. In the past I have had problems because it came as an exe file and I had to contact the organization concerned to get an alternative Mac friendly disc. In this instance the information under Find Info is that it is a volume created on 18 September 2013. It is formatted as indicated and its capacity is 135 KB. There is no indication what I should use to open it.

Understanding Mac OS Extended format for DVD media

I am typically burn my files and folders on the Desktop. The reason I do this is that I hope the files will be readable on both a Mac and a PC. They seem to be do that just fine. But it was not until today that I noticed that these DVD's end up being formatted as "Mac OS Extended" even though Windows XP with Service Pack 3 can read them just fine. But I also have an older DVD that was burned the same way and also says it is formatted in the "Mac OS Extended" format. But that DVD is not readable on my PC even though it is readable on my Macbook. I am trying to understand if something changed in the Mac operating system that changed with this format. I am also trying to understand the Mac OS Extended format and primarily what is the BEST way to burn a DVD that works on a PC and a Mac.
Thank you for any help you might be able to offer.
Garry

On the Mac, it says the format of the DVD is Mac OS Extended but when you run it on WIndows XP with SP3, it says the DVD is formatted as UDF (Universal Disc Format) which I think is interesting because I burned several DVD's on my PC in the UDF format version 2.5, which is the latest, but the Mac OS could not read them. So it must be an older version of UDF Apple is using or some type of custom format that Apple uses.

Disk Utilty - Reformating Windows-formated drive to MAC OS Extended Format

Can a drive previously formatted as Windows FAT32 or NFTS subsequently be reformatted to the MAC OS Extended format, via OS X Panther Disk Utility's Erase and/or Partition options?
If so, is it straightforward to do, or are there any potential pitfalls?

Hello! Yes, it should work fine to use disk utility to format the drive to HFS+. Tom

I am not 100% what isn't allowed.. but I am assuming you want to spread the backup across the two disks.. internal TC and 6TB external.. this is not possible.. It has to be one or the other. TC has no way to build a raid JBOD or anything else. Nor would you want to as that is the most likely to fail and kill your data.
Let me add, backing up 6TB over USB on TC.. will be the most excruciating experience of your life.. cf child birth or passing kidney stones.. large ones.. being the male equivalent.

Error -1309 large file transfers under Mac OS extended format

When transferring large video files from one firewire drive to another in OSX panther on Rocstor firewire media formatted in Mac OS extended, I am getting error -1309 and lots of problems. The new 250 gig even became unreadable, data was lost, and I had to reformat. It hung norton disk doctor and sometimes the OS reported that copy times for 7 gig files would be 936 hours.
This is a brand new rocstor drive, and frankly I do not think the drive is the source of the problem, (but who knows?) perhaps the files have become corrupted.
For example, if I try to drag a 4.8 gig file from a 75 gig firewire to a 250 gig newly formatted firewire drive, (with 230 gigs open space), it starts copying, then a minute later it stops and tells me the disk is full!
Neither diskwarrior nor norton disk doctor have found a problem with the firewire media or the files. (well, there was one, "a major error was found in the ALternate Volume HEader Block, last mounted version is invalid", but Diskdoctor corrected this) I have researched error -1309 on the internet, but there is surprisingly only a sparse amount of info about it.
On the first copy operation a few weeks ago there was not really a problem (about 61 gigs worth of quicktimes). The files copied fine. Now these same files -- some of them, especially the large ones, up to 7.5 gigs, are refusing to copy from the (second or third) generation firewire drive to yet another firewire drive.
Any insights on this puzzling problem would be appreciated.
thanks

Status update:
With a brand new Rocstor firewire 250 gig drive I am unable to record video without getting a FILE I/O error within 2-4 minutes, or dropped frames. I had just reformatted the firewire Mac OS Extended. This drive is just a couple of days old. I have other Rocstor firewire drives that do not seem to have this problem. I have been using a couple of rocstors for more than 2-3 years. Furthermore, the other rocstor drives also contained the same types of files, in an earlier generation.
The only I way I could have "contaminated" the newer drives was to attempt to copy quicktime files over 4 gigs to the funky drive. This has happened twice now, once with a 300 gig rocstor "400" less than a year old, and now with a 250 gig rocstor "400" just a couple days old. (Incidentally, I have put in two tech calls to them about this matter this week. Their recommendation was to reformat mac os extended.)
Well, this is puzzling.

Which MAC OS EXTENDED format? journaled, case-sensitive?

I'm going to be using my new Mac Pro for editing corporate videos and I want to use an external firewire800 LaCie 1tb drive from my windows computer on my Mac.
I've gone to the disc utility screen and not sure which format I should re-format it as. I've been told to use MAC OS EXTENDED but there is several flavours: journaled, case-sensitive, etc.
I need it to be as fast as possible but also reliable and able to handle large video files (e.g. 60gb HD files.

The Mac can read and write FAT32 and FAT16 volumes, and it can read NTFS volumes (cannot write to NTFS). FAT32 will only allow files up to 4 GB in size, so it's really not acceptable for video. The Mac generally reads it's own format, Mac OS Extended faster and more reliably.
If you need platform independence, you have a few options.
1 - Get Windows machines to read Mac OS Extended with special software.
2 - Get the Mac to write to NTFS with special software
Because of the way the Mac manages external hard drives, option #1 is ideal. But you should keep in mind, the Mac will run your FireWire 800 drive faster than the Windows machine not because of compatibility, but due to the fact that Windows doesn't support FireWire 800 and limits transmission with those devices to FireWire 400 speeds (or so I've been told).
The Mac Pro will partition using the GUID Partition Table scheme by default. This partition scheme is required to boot an Intel Mac, but not for simple reading and writing of data. I'm not sure what implications this might have on the ability of your Windows system to read the data, but it's worth checking. It's possible that the Windows software might not recognize GUID, but I'm not sure.
I think most people who edit video professionally on the Mac are choosing to alleviate this confusion by avoiding Windows altogether. That works very well.
Use Mac OS Extended (Journaled).
Case-sensitive can sometimes cause problems and is best avoided.
Interesting to note, Adobe software won't run on a case-sensitive volume.

Changing Sharing & Permissions on a Mac OS Extended External Drive

I'm using ChronoSync to back up to 4 external hard drives. Three of them were formatted as Mac OS Extended (Journaled), while the 4th is not journaled. On the journaled HD's, I can change the privileges for me, staff and everyone in Get Info; I can also check or uncheck "Ignore ownership on this volume" on 2 of them. My Time Machine volume doesn't have the option to ignore ownership. My issue is that changing privileges on the Mac OS Extended volume is grayed out, and the box to ignore ownership is checked. Therefore, Chronosync cannot write to the volume.
I could try to use chmod in Terminal to change permissions on this volume, but I don't know the syntax to get to a mounted volume (I know they're listed in /Volumes).
So I have two questions:
1. Does this issue indicate a substantial difference between journaled and not-journaled Mac OS file systems?
2. What is the syntax in Terminal to change the permissions on the volume (name is Video Backup) so that I can at least uncheck the "Ignore ownership on this volume"?
I apologize if this has been asked and answered elsewhere on this forum, but I wasn't able to locate such a discussion.
Thanks,
Nick

Hi mackjack,
The commands Niel posted were to regain access to a drive not to change existing permissions. Nonetheless, I executed them so at least I know the syntax to use in order to get to an external hard drive (something I hadn't known before), so thanks!!! I might try chmod 770
Update:
Now that I know the basic syntax (thanks to you) I can now change permissions for any user I like. Chronosync is able to synchronize to the drive.
Thanks!!

Mac OS extended journaled drive cannot be written to

I have two WD MyBook external drives that are formatted Mac OS extended journaled. Permissions are set for owner to write to the drive. I am the owner. Carbon Copy Cloner and Time Machine write to the drives regularly. When I attempt to copy a file to the drive a small window opens telling me "The item is not writeable. You do not have sufficient permissions to write to the item."
Any help in understand what's going on here would be greatly appreciated.

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
(On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
(Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
What's the plist file?
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
Then try select it again.

Does Time Machine automatically reformat a non-Mac OS Extended hard drive?

A friend has just told me something surprising he read in the "Mountain Lion Missing Manual".
It apparently says that if you connect a FAT or NTFS formatted hard drive to your Mac and startup Time Machine, it will be automatically reformatted to Mac OS Extended (Journaled) by TM.
Is this true?

Here is the quote from David Pogue's, "Mountain Lion - The Missing Manual"
Note: The backup drive must be a standard Mac-formatted hard drive—yet many new drives bought by Mac fans come preformatted as Windows disks. Fortunately, Time Machine automatically reformats them to the Mac OS Extended (Journaled) scheme, which it requires. Thoughtful, really.
It sounds too good to be true . . . . . can anyone confirm it?

Cannot see OS Extended-formatted drive on Airport Extreme in Finder

*EDIT: solved

I just purchased two 500GB USB hard drives and am attempting to connect them to my AirPort Extreme Base Station. They are connected to the USB port of the AEBS via a powered USB hub.
When I turn them both on, the base station goes into a restart loop. That is, it continually restarts until I power off both drives. If I turn on just one drive, it doesn't reboot itself until I attempt to connect to the hard drive via the Finder, or the AirPort Disk Utility menu. It then goes into the restart loop.
I have just run the 7.1 update for the AEBS, and had this problem before and after the update. My problem seems to be different than most on these forums, but I'm hoping the solution is similar.

MS-DOS or Mac OS Extended

Hi,
I have an external firewire 400 120GB hard disk drive that I use frequently with macs and occasional with windows, I have always used the MS-DOS format but I was wondering if there is any advantages to using the Mac OS Extended format?
Would it increase the read/write speed with a mac?

Without the installation of third part software such as MacDrive, PCs cannot read Mac OS Extended formatted drives, so if you need to use the drive on both platforms, and you don't want to buy 3rd party software, format the drive as MS-DOS (FAT).

External USB Drive (MAC OS Extended) Problem

I had an NTFS formatted external USB2 drive which I have been trying to format as a MAC OS Extended (journaled) drive to use with my iMac. After partitoning it with disk utility using the MAC OS Extended partition scheme the drive will not mount and attempting to run first aid on it results in an unspecific error message.
I even went as far as zeroing the drive to see if it would mount. No go. If I format it (using disk utitlity) as a FAT32 drive the drive mounts without a problem. The drive also mounts without a problem on a PC.
I'd appreciate if someone could explain why formatting the drive with as a MAC OS Extended partition makes the drive unmountable and if there is a fix for it.
Thanks

I don't want to use this as a drive on both a PC and a Mac, just the Mac. If if leave it as a FAT32 the Mac can use it however the file sizes are limited to 4GB which is not good. I have some files from iMovie and QT that need to be stored and which I don't want to have to break up in order to put them on the drive.
I'm still surprised that the the process of converting a PC drive to a Mac drive is not easier. Especially since more people are starting to move to Macs.
