Betadeck to iMac, SDI- external HDD speeds?

Im trying to capture from a betadeck with an IoLD via SDI to my iMac's external Harddrive.
I am getting constant dropped frame errors.
My external harddrive is a 5200rpm drive. We are guessing that the drive speed is too slow, and the information is too much to handle for the drive.
Will a 7200rpm or 10,000rpm drive fix my problem, or is it something else?
Thanks
-Mike

Good guess.
5400 RPM can barely manage DV. Now that you are getting into uncompressed SD, you need a FW800 hardware raid solution, like the Firewire VR by CalDigit or G-Raid2 by G-Tech.
Oh...wait, you already have the I/O LD connected via firewire...and you are on an iMac. Well...this setup is less than ideal. You only have ONE firewire bus, so using it for both the capture device AND the media storage won't bode will. Dropped frames will be very commonplace. iMacs ain't designed for uncompressed work..this is why. You really need a MacPro or MacBook Pro that have expandability...ability to add additional firewire buses, or connect to eSATA RAIDS.
So it isn't only the drive speed, but it is the iMac.

Imac and external hdd

im trying to boot from external hdd and efi bios does not even see the external hard drive!!!!
i work at the educational facility and i just got 40 imacs that have to be cloned!!!
doing every one of those by hand would be a nightmare.
does apple actually provide any tools except netboot and netinstall that would help me with the quest?
any tricks i have to do on the mack to recognize external drive as a boot drive?

A good source for how to do netinstalls is www.bombich.com.
You fail to tell us anything about this external drive, how it's formatted, what's installed on it, etc. The general rundown is:
You need to partition the external drive using the GUID partition scheme. If the external drive has never been formatted before then format the drive Mac OS Extended (Journaled.) This should be done using the OS X Installer Disk One that came with the computers. If the computers are all the exact same model then you only need use one of the installer discs. However, if you have different hardware, then each different model has a different build of OS X. You will need two different external drives or you will have to update the system on the external drive to one that will be common for all the models you have (this would be 10.4.8 (Intel).
Here's the procedure:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disk. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger.)
2. After DU loads select your external drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Click on the Option button and select the GUID partition map and click on OK. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
After formatting is completed quit DU and return to the installer. Now quit the installer. The computer will reboot. After reboot clone the system on the iMac to the external drive:
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the backup or destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
6. Select the startup or source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
8. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked. Verify the settings for Ownership and Permissions as follows: Owner=system with read/write; Group=admin with read/write; Other with read-only. If they are not correct then reset them.
For added precaution you can boot into safe mode before doing the clone.

IMac with external HDD backup to Time Machine

I have an iMac with a 1TB internal HDD and have run out of space due to the number of photos in my library. I want to move the photos to a 1TB external HDD, then add a new 2TB external HDD to serve as the new Time Machine backup drive. So my setup will include the iMac and two connected external HDDs. What is the best way to set this up so the new Time Machine backup drive captures both the internal iMac HDD and the external photos HDD? Any tips or tricks would be appreciated. Thanks!

First of all, note that Time Machine can only make backups of drives formatted in HFS+ (known as "Mac OS Extended (Journaled)"), so your 1 TB external drive has to use that format before moving your photos to it. As you are using it to make Time Machine backups, it is already using that format.
There are two possibilities in order to start using a different external drive for Time Machine:
Move your old Time Machine backups made in your 1 TB external drive to your 2 TB external drive.
Start a completely new backup, deleting the old ones.
In the first possibility, you only have to follow these steps -> Time Machine: How to transfer backups from a current backup drive to a new backup drive - Soporte técnico de Apple After moving your Time Machine backups to the 2 TB external drive, remember to format the 1 TB drive with Disk Utility in order to store your photos there.
In the second possibility, just go to System Preferences -> Time Machine, and choose your 2 TB external drive as your Time Machine drive. Then, format the 1 TB external drive.
In both cases, Time Machine does not make backups of external drives by default, so after moving your photos to the 1 TB external drive, you have to go to System Preferences -> Time Machine -> Options, and remove the 1 TB external drive from the excluded items list. By doing that, the next backup will also include your 1 TB drive.

External HDD shows up on Macbook Pro but not on new iMac

I recently purchased a new 21.5" iMac and when setting it up, I utilized the Time Capsule backup from my Macbook Pro; everything seemingly went fine and my iMac was set up with all the data on the Time Capsule at the time (last update was a few months ago). Once everything was ready, I signed into the Mac App Store and downloaded the Yosemite upgrade (the iMac came with Mavericks). All the while, the Western Digital External HDD was not connected to the iMac.
Once everything was complete, the system rebooted and I was off and running with my new Mac.
The problem comes in when I tried to plug in the WD; everything lights up and it seems like the system is picking up the drive but then it just hangs there. It does not show up on the Desktop or the side panel in the Finder but it does show up in Disk Utility. When I verify the disk, it tells me that it is not mounted and when I try to mount it, it tells me that I cannot and to try to run First Aid on it. I have run a Repair disk and that made no difference.
The real head-scratcher is that the Macbook still picks it up without any issue but the new computer does not.
Can someone please help?
P.S.
The WD was never formatted for Mac since it worked on the Macbook right out of the box and now I have about 500+ GB worth of info on there that I would rather not lose.
Thank you.

It's something I can look into doing although I don't have a spare drive to copy all of that to and/or am not really looking into getting another HDD.
I am mostly wondering if anyone can provide an answer, or rather a reason, as to why it will legitimately work on one Mac (without any issue) and not on the other...especially if the new system has been set up using the information from the first one.

I am new with iMac and I am trying to copy some file from my external HDD but it does not let me also I can't delete anything from this HDD using the finder. Can somebody help me , please?

I am new with iMac and I am trying to copy some file from my external HDD that a used with my PC but it does not let me also I can't delete anything from this HDD using the finder. Can somebody help me , please?

No, unfortunately, when you format a drive, it will erase all the contents. So you will need to find a temporary "storage" place to put the stuff using a PC so you have access to it. Then reformat using Disk Utility (Applications > Utilities). If only using with mac, format Mac OS Extended (Journaled) and use GUID Partition scheme under Partitions/Options. After formatting, you can drag the files back.

I upgraded my imac to OS Mountain Lion and now the Seagate Goflex external HDD is not recognised

I upgraded the iMac to Mountain Lion and it does not recognize the Seagate Goflex External HDD that I was working from earlier. I do not want to buy a special program since the Goflex HDD was working on both mac and Windows without any problems before the upgrade. The Goflex HDD is still working on my Macbook pro so there is no problem in the HDD. Is there something that needs to be activated... Please help

A bit more info for those of you reading this.... the problem seemed to be in iTunes. For each connected device , if I clicked on the Photo option I could no longer select the second radio button for limiting the photos by Events, Albums, etc. It was an all or nothing deal. But selecting all would cause the error.
So I had read the other forum posts about the "&" symbol being the cause of the problem. I went through iPhoto and made all of the changes. It did not work. I then looked at iTunes, using the AlbumData2.xml file listed in the other forums as a reference. I found one album with the "&". I edited that one. Still would not work. So then I spent 3 hours on the phone with AppleCare last week. I talked with 4 different advisors. None of them had heard about the "&" error from the forums. We tried everything in iPhoto including repair and rebuild. Finally we created a whole new library and reimported my master photos from my original one. Using this option would allow me to now check off that radio button in iTunes. BUT... I now lost all of my albums and events and would need to rebuid them. I was not happy. They agreed and we set up time to talk this week.
So today I talked with AppleCare again. They now have more info and said the problem has to do with iTunes and the new iPhoto 9.4. It does not like the "&" symbol anywhere in either iPhoto or iTunes. So they now have me going through everything in my iTunes library. Genre is OK but any other item cannot have " & ". I have several dozen to edit and will do it over the weekend and then restore my original iPhoto Library and see if I can finally get it all to sync. I will let you know how I make out, but apparently you need to eliminate " & " from every entry in iTunes and iPhoto.
Quality control is not up to par with Apple these days.

IMac keep ejecting my 2TB external HDD but in safe boot mode it is totally fine. How to resolve the problem?

Hi,
I have WD 2 TB external HDD. It has two partitions, one I use for my time machiine backup and one for my personal files and documents. Recently the iMac keeps ejecting the external HDD as soon as it gets connected to the iMac. I tried to reboot the computer in safe boot mode (by holding down the shift key at startup) and found out that problem is not there anymore. I can access my external HDD there and it never ejects the HDD.
It seems like the HDD is fine, the problem is with the iMac. Can anybody please give any solution to this problem?
Thanks!

Thanks Allan for your reply!
It makes sence that there must be some log in /start up item which is causing this problem. I went System Preference>Users & Groups> Login items> disabled all the items there to make sure, and restarted the computer but the problem is still there
Is there any other way to stop/configure the log in items?
Thanks again!

My iMac running lion will not sleep if an external HDD is connected.

My Imac will not sleep if the external HDD is connected. This just began to occur. If I unplug the drive it goes to sleep. This doesn't happen with any oter USB pereferals.
Thanks in advance.

Click the Assist me button and select Assistant. Follow the prompts. How far do you get?

Is it possible that iMac corrupts connected external hdd-s drive via USB?

Is it possible that iMac corrupts connected external hdd-s drive via USB? (two wd cav. green 2tb from different purchase went down in one day, both from the backside usb ports)
First one of my video storage hdd, full of files suddenly got extremely slow, and a few minutes later, it unmounted itself, but with the unmount error, but nobody even touched the cables, electricity etc. When I tried to mount it again, it did not respond, just give a periodical load light and ticking. First I thought it must be hardware failure, but since I bought a brand new drive today and it made the same problem as soon as I tried to format it. I got suspicious. The consol, said about these - i googled all but now solution so far. (WesternFresh is my drive)
Oct 23 17:10:58 xxxx fseventsd[47]: disk logger: failed to open output file /Volumes/WesternFresh/.fseventsd/636573acca1d6550 (No such file or directory). mount point /Volumes/WesternFresh/.fseventsd
Oct 24 10:55:42 xxxx com.apple.kextd[10]: Can't create kext cache under / - owner not root.
Oct 24 17:23:05 tmdc diskarbitrationd[16]: unable to probe /dev/disk1 (status code 0xFFFFFFFA).
and there was an I/O faliure not but it was on another mac - where i hoped itt will come back to live.
I think - if it is possible - that the OS maybe misunderstand something about these drives, and try to change - maybe permissions - all the time if a usb external connects...? (I am not really into it as you see )
Also about Disk Utility - it does not see any partition on the old hdd, but i shows the name of the product. If I connect the new hdd via the keyboard usb, the disk utility is able to see and format it, but the hdd will be still slow and tikking after it.
Also I tried Disk Warrior (freezd out) and Techtool Pro 6 thanks to some ol'frineds - which also not saw the old hdd, but did nothing useful with the new one.
About cav green: I have 3 of them and no error so far, and got 4 1tb cav green in 2 mybook studio II also without any problem.
Iam a bit scared, and try not to plug in any usb hdd-s now, but I have to continue work, so I need solutions.
I hope if it is not hardware failure, maybe some tricky terminal code will bring back the viability of my old hdd - and I won't have to spend a lot of money to recover data.
strange.
if anybody has a clue?
update 1:
i found this post also:
https://discussions.apple.com/message/15905481#15905481
I also made the mentioned steps - but it is a bit different sice it reproduce itself and I cant use DU.

It turned out that WD is the big bad guy in this game.
According the data rescue company where I asked for an inspection, both of the drives had their reader head loose. And in the one, which was my already-in-use disk its even damaged the platters... xxxxx
So its time to pay bunch of money to recover, and take a walk to wd service to bang on the desk.
Also note - it may be somehow related to intellispeed technology - since macs not really friendly with wd-s built-in solutions.
On the other hand, with WD GP 1Tb there is no problems at all for ages.
thanks guys, thread is closed

Why is Lion installed on external HDD and iMac says that Lion is already installed when it is not?

I went into the Apps store then logged in to confirm that I wish to pay for the Lion upgrade from Mac OSX v10.6.8.
The downloaded 3Gb installation file went into my Applications folder after a few hours:
This installation application is still in the Application folder of the iMac.
During the upgrade / installation, I got the following message, saying that the installation can't go in the HDD of the computer I was working on (ie. the iMac's Macintosh HD). I had no choice but to select the external HDD (WD-1T) as the installation destination, which proceeded very quickly.
When the installation was complete, the iMac rebooted into a fresh Lion installation, running off the WD-1T! I can see all my old files on the Macintosh HD, as if that HDD was the external HDD!
If I disconnect the WD-1T upon rebooting, I am back to Snow Leopard, running from the iMac's Macintosh HD. If I go the App store, it tells me I have already installed Lion on the iMac (when it is not the case)!
When I go to my MacBook Pro (currently on Snow Leopard and not part of from the above installation), I see that Lion is purchased but not installed. If I click INSTALL, it starts to download what the iMac had earlier downloaded (the Install Mac OS X Lion.app is still sitting in the Application folder of the iMac).
Question:
Can anyone shed some light why this happening and how to get Lion onto the iMac?
How to install Lion on the MacBook Pro without re-downloading the software?

I would say it is related to the purchase date. FaceTime is included in 10.6.6~8 OEM discs.

USB vs. FW External HDD Transfer Speeds

I recently (yesterday) bought an Iomega minimax 250GB external HDD to go with my imac. I know that this is desined for the mac mini however I liked the USB/FW hub capability and the small footprint.
The main purpose was to clone my 160GB internal HDD and use the remainding space for DV capture and editing.
I have noticed that the transfer rate between the USB2 and FW conections is very different. I am getting approx 13MB/s from the USB2 and 30+ from the FW and was wanting to know why the USB2 was so slow. The HDD is connected directly to the back of the imac and the only other USB2 device conected is the keyboard.
I know the simplest answer is to forget the USB2 connection however to ustalise the USB and FW hub capability I need to have both connected and the system does not seem to allow me to set 1 as priority over the other and the USB2 is the default.
Any suggestions would be greatly appreciated.
Cheers
Daniel
iMac G5 17 2.0GZ Mac OS X (10.4.6)

I was not aware that you could prioritize the usb/fw
connection. I just assumed that fw was the default
when both cables were connected. How do you
prioritive the connections? I am not sure what the
value of a hub is because both usb and fw devices can
be daisy chained. I have a combo ext. HD with a usb
hub but I only use the FW port. Keeping the usb
connection also takes up a port on my IMac.
Sorry been away for a bit. There is an Auto/1394a swith on the back to switch between the Firewire and auto. Has made a significant diff setting to FW over the USB2.0.

IMac g4 not reading external HDD

hi everyone;
I have an imac g4 700mhz sitting around the house i was going to use just for itunes, it is running tiger, i have an external hdd from a pc with all my music on it, when i plug the drive into the imac, the drive is not found, i looked in disk utility and there is nothing there.
I've also tried all the USB slots on the mac, the drive gets power from the usb port, but osx isn't recognizing the drive.
Drive model number: Western Digital WDBABM7500ABK-00 running osx tiger 10.4.11
thoughts?
Cheers,

Please permit me to disagree: drives formatted by PCs using the FAT32 system can be read & written-to by Macs but if formatted using NTFS can only be read.
Given that you have a 700MHz iMac, it has USB1.1 ports which I suspect aren't providing sufficent power for the device to be recognized. The port immediately adjacent to the modem port gives little better supply as the other two share power. Do you have a power supply for the external or perhaps the drive came with a USB cable with three plugs on it like the one below?
kind regards

Can I boot a Windows OS on my iMac from an external HDD?

I have two hard disk drives:
One is inside of my 2009 iMac, running leopard. Also on my internal drive is a Windows OS partition, currently running windows 7. One is a WD 1TB external HDD, which I boot Mountain Lion off of. The thing is, I'm running out of room on my internal hard disk drive. Since it is entirely possible to boot Mountain Lion from my external HDD, would it be a good bet that I can make my iMac do the same for a Windows OS? Or is this not the case?

Microsoft does not allow a installation of any version of Windows on an EHD. This is not an OS X or iMac issue,it's strictly with MS Windows.
However, some people have developed hacks to make installing Windows on an EHD possible, the keyword is hacks so you are left on your own to find out how to do it and support it.
Sorry for the discouraging news but unfortunately that's how it is.
As a work around I'd recommend moving large libraries to another EHD, examples of large libraries are iTunes, iMovie & iPhoto. Apple provides instructions on how to do this, you can find them at:
iTunes: How to move the library to an EHD
iMovie: How to move the Library to an EHD
iPhoto: How to move the Library to an EHD
If you make these moves then you can do a standard installation of Windows on your iMac using either Boot Camp or virtualization software such as Parallels or Fusion.

You are still under warranty and/or have AppleCare. Call them. Let them deal w/it.

Thunderbolt, External HDDs and an iMac connectivity

Hi,
So I have the aluminum unibody 13inch macbook. (Snowleopard) I also have a mid 2011 iMac 27 inch. (Lion)
I am looking into buying a RAID arranged external HDD, such as the LaCie 2Big 6tb or WD 6tb units and would like to utiliise the associated sped for video editing. However both see to only have thunderbolt connections.
I frequently shoot video in the field and load for preview on my Macbook. So how would I go about getting the media from the macbook to the RAID media store once I'm back at home?
Can I:
Connect the macbook as a tethered disk to the iMac and then use the iMac to transfer from the Macbook to the RAID? I appreciate the transfer limitation will be the USB connection to the macbook in ths case, but would it work?
As an additional question, since the Macbook has wifi and ethernet connectivity, which would be the fastest data transfer rate that I could use?
Thanks in advance, any other solutoin would be appreciated...

BDAqua, 480Mbit/s vs 100Mbps. Is the former in MBITS and the latter in MBYTES, meaning wifi is much faster?
Secondly, just to confirm my understanding, the situation above I would effectively be using the iMac as 'pass through' device, transfering data direct to the HDD without efecting the iMac storage. I appreciate this sounds very like pretty novice questions, but then its because I am. Much appreciated.
Thanks
