External Drive Reading Problem

So,
I'm transferring files to my Mac using a FreeAgent Drive by SeaGate. I click on the external drive button and I see the files, but when I click on them, they disappear. I view the files on my other machine, they open up with no problem. What gives? I'm assuming that this is a setting problem since they are viewable on the other comp. What gives? Any Settings I need to tweak?

If your Mac were older, it would probably work fine. Before 10.4, the Mac would have treated it as a "foreign" file system and mounted it and read it just fine.
In 10.4, the advent of the Intel Macs meant that you could now boot from Windows-formatted drives, and Windows formats were now "native".
I know the history, but I do not know the implications of Windows formatting. It should be FAT-32, but I don't understand what the Mac is trying to do with it that would make the Icons jump around or disappear.
There is a hint that there may be trouble in this document. It suggests that when you want to copy a bunch of Windows documents, you put them in one Folder on your Windows machine, then copy that one Folder, then open it when it gets to your Mac. I think the key is that the files are hidden in folders, so that exactly which Icon they should have, and where they should be in the window cannot cause confusion.

I am moving from PC to Mac. My PC has two internal drives and I have a 3Tb external. What is best way to move the data from the internal drives to Mac and the best way to make the external drive read write without losing data

Paragon even has non-destriuctive conversion utility if you do want to change drive.
Hard to imagine using 3TB that isn't NTFS. Mac uses GPT for default partition type as well as HFS+

You can install NTFS3G, this will allow you to write to an NTFS drive

IMovie 6 Why? audio extract, copy file to external drive, delete problems

Why are these problems occuring in iMovie '06
+the remaining clip, after an audio extract, no longer has audio, and the extraction does not only extract the selected clip, but the whole movie
+copy and paste an iMovie (.iMovieProject) file 10.66G to a 30G external drive results in "error code 1309" and fails to finish copying
+a 10.66G movie where about 99 percent of the clip was deleted still reads as 10.66G even though the clip is only 26 seconds long.
Premature release of program me thinks.
Powerbook G4 12" 1.5Ghz, 768K RAM Mac OS X (10.4.4) also a powerbook G4 15" 1.25Ghz 256K RAM (with only one good RAM bay)

Welcome to iMovie Discussions ..premature posting of question, methinks. (..without, perhaps, having searched for or read any previous discussion of these or similar topics..)
a - This is the iMovie HD (version 5) Discussion ..there's a separate area for iMovie HD 6 ..but I'll still be happy to answer your questions!
1 - When audio is "extracted", the original clip is simply muted, and a copy of the original audio from it is pasted into a separate audio track below the video. Normally, you'd select an individual clip (or clips) from which to extract (Copy) the audio. If nothing specific is selected, then everything may be extracted.
2 - An external drive must be formatted as 'Mac OS Extended' or HFS+ for iMovie to be able to work with files stored there. It may be formatted in PC (Windows) FAT 32 format, and there may be a file size limit in that format which is incompatible with your Mac operating system. See this page of error codes, where "error -1309 fileBoundsErr: file's EOF offset mark or size is too big" ..that means that the End Of File marker is incompatible with what's being copied. Googling will find other info, such as this discussion, which prompts a handy reminder that your external drive must be connected by FireWire, not by USB, for you to be able to edit and play via the external drive: a USB connection isn't consistently fast enough for playing video.
3 - When you delete part of a clip, in iMovie HD (any version) all the rest of the material is still saved, in case you want to Undelete, or make other alterations which need still having access to the original material. [ This is part of the enhanced "non-destructive editing" which was recently introduced into iMovie. In previous versions, when you deleted something, it was irretrievable! ] That's why the full 10.66GB remains. You could 'Share' (Export) just that 26 sec clip to DV, then re-import it as a new clip, and you could then delete the entire original clip, thus regaining the full 10.66GB of space.
So it's not a premature release: it's a considered, robust, thoughtful release, which now incorporates several solid features which make it more reliable than some previous releases.
Once you get to know how - and why - it works the way it does, you may be glad that it does work as it does.
There are still some bugs in it - many to do with "rendering" ..the rewriting of adjusted video, particularly of adjusted still photos within iMovie - but don't judge it just on a quick first glance!
Hope you find it works for you ..it's a great program, I think.

External drive boot problem

I have a Verbatim USB external drive plugged into my iMac used for backups with time machine. When I start the computer it immediately stops at a blank white screen. If I turn the computer off and unplug the external drive and restart it works fine. Is there anyway to make the computer boot with the external drive plugged in?

Open Sys preferences then Startup disk and select your internal drive and click Restart then again restart from the drop down that Drops Down.
Once you have done that and the system restarts shut it down and connect the external then start it back up. It should now go to the internal drive automatically.
If it doesn't then you have some other problem which may be a hardware problem. Post back with your results.

External drive recognition problem

I am having issues with my iMac recognizing an external drive. I have:
iMac 5,1 10.4.11, Intel Core 2 Duo 2 GHz, 1GB Memory, PIONEER DVR-112d in a BYTECC ME-525U2FW Aluminum External enclosure connected through Firewire.
The iMac initially recognized the drive, no problem. Trouble is, when I turn off the drive and then power it back up, the iMac can't recognize it. I was able to solve it initially by powering down the drive, unplugging it from the firewire, reconnecting to firewire, and the powering up the drive again.
System profiler states all software up to date.
Any suggestions would be appreciated. Thanks!
drayman86 is online now Report Post Edit/Delete Message

Thanks for the reply.
Has performed this way since install, which was about 72 hours ago.
When first connected through firewire and turned on, drive immediately recognized by iMac. Drive works, both ripping and burning. Turned drive off. Went to power up drive, and problem arose.

External drive disconnection problem.

How do you go about keeping external drives connected when the computer goes to sleep? I have eexternal drives connected to both the iMac and Macbook Pro, When they go to sleep, somehow the dirves get disconnected sith "disk not ejected properly" messages. This happened some with Mountain Lion, but all the time with Mavericks. I have Seagate drives on the iMac, and a WD My Passport on the laptop.

Hi,
I was also facing this problem for a long time.
I tried many ways to get this thing rid off..
In my case i was using a WD external hard disc which was NTFS windows partitioned.
So i was using TUXERA which is a 3rd party app to enable write access with this NTFS Drive.
I simply uninstalled this app, and the disk eject was Successful.
If yours a similar problem, hope it helps you.
Peace!

Time machine back up failed on my external drive & more problems

Hi,
I'd be grateful for any help.
I have a G-TECH 1TB external drive (7 months old) and decided to use that with Time machine to back up my files. I hadn't used the drive for about 4 months but it had worked fine the last time I used it. I connected it to Time Machine and a back up failure message of some kind appeared. Since then the drive is unusable... I'm lucky if I can get the drive to mount ("the disk you inserted is not readable by this computer)" yet I can't reformat it - disk utility can't erase or partition it. It throws up a variety of error messages (can't unmount drive & resource busy are a couple) which usually ends with the spinning ball of death. Tonight I spent my hard earned money on Disk Warrior, which appeared to check and rebuild file systems and the drive mount now mounts but I still can't reformat it or use it in any way. Have now spend hours trying to mount and reformat it and it's driving me mad...
Thanks very much.

Hi Pondini,
Yes, I bought DiskWarrior 4.1.1 - it came up with this report:
" DiskWarrior has successfully built a new optimized directory for the disk named "Untitled."
The new directory is ready to replace the original directory."
Did you let it do that? If not, nothing was changed!
The drive is still under guarantee - can they really fail this quickly?
Sure, a few drives from any production run will be D.O.A, and a few others will fail very quickly, as with nearly any manufactured product.
But you don't know yet whether the drive is bad. If you didn't let DW replace the directory, run it again and do so.
If it's still troublesome, try the other things in my last post before deciding it's the drive.

External Drive Read/Write

My access to my own external drive has become tenuous.
Everything worked fine until I created a new user on my MacBook that was actually a Time Machine backup of my G4 that Migration Assistant brought over (that computer went down). Somewhere along the line, I realized that my main user account on the MacBook (the original user) was being locked out of certain resources on my Lacie 250 GB external drive.
In the Sharing & Permissions arrow of the Get Info on the drive, it says I have custom access. The owner is listed as (unknown) and can read and write; there is also a group called Everyone, but this group has no access. These names are grayed out. When I click on the plus sign or the configure wheel and try to add a user, whatever name I type in merits the message: The name you entered is not valid. Please try again.
What has happened that I can't access my own drive and how can I remedy the situation? Any thoughts would be appreciated. FYI, I'm an intermediate Mac user who can work with Terminal if commands are provided. Thanks!
Grant

In the Get Info window and the Sharing and Permissions section (I don't have an Ownership and Sharing section), first off there's no lock and I'm not prompted to authenticate. When I try to change privileges of the two users that are already there (unknown and everybody), nothing changes. And when I click on the plus sign to add a user, I'm not given a list but only a window into which I must type a name. I've tried every name I can think to put in there, but haven't had any luck getting one of them accepted.
Because this might help, here's how I have things laid out:
The MacBook is named Gieseke. The main, original user is Grant (shortname: granta). The user I added is Geesekey (shortname: geese). I also have two other users that System Preferences lists as sharing only: Grant & Amy Gieseke and Guest. I've tried typing each of these names in as a new user, but none of them have been accepted.

External Drive Formatting Problems - Please Help!

I formatted an external drive (just a 1gb memory stick, i intend on formatting an external hard drive i have coming in the post in the same way. This is to test that it will work) with 2 partitions.
Half in HFS+ for my storing documents from my intel imac and the other in FAT32 to use as a windows partition to store documents from my windows laptop.
(I know that FAT32 works with both but FAT32 has a 4gb transfer limit and is general untrustworthy - if possible i'd rather format the windows partition in NTFC if possible?)
I'm doing the formatting/partitioning in apples disk utility and it appears everything works fine, my mac detect both partitions as separate drives as its supposed to.
However, when i then insert the drive into my windows laptop it detects the drive and tells me that it needs to be formatted, i say yes... and it formats the whole thing as FAT32, whereas i want half FAT32 (or preferably NTFC) and half HFS+.
I tried formatting half as HFS+ and half as 'free space' (again with apple disk utility) then inserting it into the windows laptop, it asks me to format it and it formats just the HFS+ side into FAT32 and the 'free space' stays that way.
Does anyone have any solutions to this?
Any help would be MUCh appreciated.

In Disk Utility, when you partition (tab) again, click on "Options..." at the bottom, then change it to Master Boot Record so your PC is happy.
MacFuse 2.0 can read, write and create NTFS and other foreign formats.
http://code.google.com/p/macfuse
http://apple.slashdot.org/article.pl?sid=08/12/17/167220
Disk Utility defaults to GPT and puts small 200MB GUID, adds an EFI partition for each user volume, and those are what probably confuses Windows, especially XP.

External drive partitioning problem

while trying to resize partition on my external drive with disk utility I get a message:
Partition failed with the error:
Filesystem resize support required, such as HFS+ with Journaling enabled
Disk format is Mac OS Extended (Journaled) - isn`t it HFS+? Then, what am I doing wrong? It is important to me not to loose my data

Rod,
Finally solved the mystery. Obviously, it would not be in the Help section, even though I had followed the directions exactly. Once I typed in the Size: 70GB, I then had to click on the left hand grey, partition box. At that moment, the box enlarged and the 70GB did not change in the Size window. How is one supposed to know to do all of that????
Anyway, it worked.
By the way, the Apricon Enclosures came and the setup was extremely easy. Took about 5 minutes and it was a Firewire External Drive. I got very good support, getting answers by email and phone in hours, not days. They are even sending me a cable that was missing. No Problem.
Now, I will work through the SuperDuper program. In corresponding with them, they suggested strongly that I Clone, and not Image the drive.
Thanks
Herschel

External drive/OS problem with itunes

I had itunes installed on an external drive, thought everything was there and safe, but now after my C drive on my computer has been swapped out to upgrade to Windows 7, I don't know how to make itunes work again. There is an itunes folder on my external drive, and a media folder that sems to have about the same amountof data as is on my ipod. Can't see anything that looks like a program file. Do I need to reinstall itunes, and if I do, will my ipod and phone fill the library and apps back in? i did a backup a while ago, but not recently, and the change to the computer happened before I had a chance to do a new backup. I'm not smart about iTunes; thanks for any help.

I'm back at my computer....I do have .itl files....here is a screenshot of what I have inside the iTunes folder on my external drive, plus I have the media folder:
So what do I do.....do I sitll have to reinstall iTunes? My plan had been to eventually move the external drive and iTunes to a different computer. Thanks.

ExFAT external drive permissions problem

Hello,
I have a new iMac running Mountain Lion. I have setup an external drive (iomega 1TiB) with two partitions, one for time machine, the other for sharing and storage purposes formatted with ExFAT. Few days ago, both partitions went unexplicabily into read-only mount mode. While the time machine partition had low occupation I just reformatted and restarted time machine. The other partition I would like to solve without reformatting as I don't want to copy everything to the iMac and then move it again to the external drive. Moreover, I'm afraid it will happen again. Any hints on why this happened?
Thank you
RL

I've tried everything I can think of to reformat this disk. Originally it was formatted for MSDOS but reformatted for the Mac. I can access the files on the drive but I don't delete them or erase the drive and reformat. I can't partition the drive. Everything is greyed out. I've tried booting to recovery drive and trying to reformat it there wihtout success (still all greyed out). At a loss to understand. Verify reports it to be okay:

External Drive Reads Burned DVDs

I replaced the original drive with a Pioneer that lasted about 1 year, sent it in for repair and got a sony. It does the same thing as the pioneer, burns but won't read dvds. Tried serveral brands of dvds, no change. It reads commercial dvds and cds cdrs ok. So I took the pioneer when it came back from service and hooked it up to a usb case and it will read the burned dvds.?! I guess you need an external dvd reader......
Steve

Several of us create a disk image, burn a DVD, and move the disk image (.img) to an external HD for future use.
Don't count on any recordable DVD to be good "down the road." Well, maybe Verbatim's Archival Grade DVD.
BTW, If I'm doing movies, I export the edited version back to MiniDV tape. That's the best backup.

Time Machine Turns External Drive Read Only

Folks--
I went away on vacation in December 2010 and shut my mac osx 10.5.8 desktop computer off, and with it my lacie 1T external drive, partitioned into three volumes, one of which served as my Time Machine backup volume. When I returned from vacation in early January 2011, Time Machine said that the volume in question was no longer available. Somehow it had become "read only." When I tried to fix it using Disk Utility I was unable to even verify it. When I tried to copy the files from the volume to another drive so that I could reformat, I received error message 1426. I'm feeling a little stuck. It seems like the only option is to reformat the entire drive and lose all of the back ups (the other two volumes have older backups).
Any suggestions?
Thanks.

Is it really corrupted? I can still access all the data on the volume, I just can't copy it or get the volume out of the read-only status.
Yes. If OSX marked it "read-only," it's corrupted.
Time Machine backups are intricately linked together; anything corrupted means the whole set is suspect. You may be able to restore some things, you might even be able to do a full system restore from some backups; but somewhere, something is corrupted. OSX knows that, and won't let you resume backing-up to corrupted backups, or copy them (even if you could copy them, the copy would be corrupted, too).
