Having bad luck with external drives

I installed Sonnett drives about 4 months ago ( 4TB ) Two drives have already gone bad. Sonnett has been good and shipped new ones but I wonder if I can keep things simple and go back to internal ATA
drives. I can install 3 1TB drives in my mac pro and that will give me enough space. ( and I won't miss the fan noise in my very small suite ) My question. I shoot in XDCAM HD, capture in ProRes. Will these internal drives be fast enough? Any thoughts? Thanks for any and all input.
Best,
Tom

GO HERE and download the AJA Data Rate Calculator Application Version 6.0.1.
It's a tiny little app that helps you benchmark drive throughput.
With an eight drive system (in RAID 0) I'd hope you'd be generating over 400 MB/s
A single internal isn't going to get that. If you were to connect the three as a RAID 0, you should get north of 200MB/s.
Whether this will work for you or not all depends on how many streams you need to pull through the system. The number of streams includes renders, effects, and so on.

  • I'm having bad luck with motherboards from Newegg.

    Hi all,
    I have successfully built several systems from the ground up with motherboards from Microcenter. However, I'm having no luck with the 2 motherboards i got from Newegg.
    The first one, ASUS P6T, would not reboot unless the reset button was pressed a few times. Then i ordered the GIGABYTE GA-EX58-UD5 X58. I had high hopes but it  too came out of the box with a problem. It start/stops/starts/stops.... I discovered that if i remove the 8pin power connecter, the mb starts but still will not post. I removed and replaced all components including the PSU and still no joy.

    The original PSU i got two weeks ago for the new system is a PC Power & Cooling (PP&C )910 watt unit. I think thats plenty of power. The PSU tester diaplays the following:
    +5V = 5.3
    -12V = 12.2
    +12V1 = 12.3
    +12V2 = 12.3
    +3.3V = 3.4
    5VSB = 5.3
    P.G. = 300ms
    I plugged the PP&C 910w PSU as well as a completely different 400w PSU into the GA-EX58-UD5 with the following components removed - no drives, cards or case fans and all drive/audio/usb connectors disconnected - just the i7 920 CPU and ram - the mb acted in the same manner.  Actually, its the PSU that's reacting to the motherboard i think. I can hear both  PSU's "click" like its tripping a breaker then resetting - hence the mb starting and stopping.
    Anyway, after i removed some and then all of the ram, the system started without stopping but still no post.  I have also been getting a debug error code of 62. From what i understand, the error code indicates that the motherboard is not recognizing the ram.
    It would appear that your both wrong in this case.
    I searched the internet and found some posts where either the bios has to updated to accept ram i have or the ram has to be replaced with something the GA-EX58-UD5 likes. In one post,  the current ram, Crucial DDR3 1066 (thats what i got), was replaced with Corsair XMS3 1333 ram and the system booted up.
    I'll keep you updated.

  • Having bad luck with new PSUs again

    Hi,
    I just recently bought an Antec 430w truepower PSU to replace my old Qtec "550W" psu since the Antec 430 w has greater max currents as I am going to upgrade my video card and add an extra HDD.
    When I try to run CPU-intensive programs, my system eventually halts with the Antec power supply installed, with the Qtec, everything ran fine. This is running a program I made that utilises the video card (open GL application)  whilst running winamp.
    My system is:
    MSI K7N2 Motherboard
    Ahtlon AMD 2600+ 333 FSB
    512 MB DDR 3200 (400 Mhz)
    1 HDD
    2 CD/CDRW drives
    also:
    Geforce 3 ti 200
    Soundblaster Live soundcard
    onboard network
    floppy
    Antec truepower 430W or Qtec "550W" dual fan gold.
    I took results using MSI PC Alert before hand from the Qtec power supply and when I got the Antec I took similar results. The results are for the CPU vCore, 3.3v, +5v & +12v rails.
    ===============================
    Qtec:
    Code: [Select]
    QTEC 550      vcore        3.3          +5           +12
    idle          1.63+/-0.02  3.37+/-0.04  5.12+/-0.01  12.03 +/- 0.03
    active        1.62 to 1.65 3.33         5.13         12.00
    Qtec proved stronger than Antec...
    ===============================
    ANTEC 430 TruePower (case open)
    Code: [Select]
    ANTEC 430 TP  vcore        3.3          +5           +12
    idle          1.67+/-0.03  3.29+/-0.03  4.97+/-0.01  11.94 +/- 0.0
    active        ----------------- SYSTEM HALT -----------------------
    ===============================
    MAX AMPS
    Code: [Select]
          Q-Tec 550W   Antec 430W TP
    3.3        20            28
    +5         35            36
    +12        14            20
    This can prove that either my Antec powersupply I received is not doing the business (430 W) and is not as good as Qtec "550 W", Why? I don't know if I should take it back and get a replacement since it boots up my machine fine, just the rails are very weak for the Antec which is supposed to prove stronger than the QTec.
    What should I do if I want to add new peripherals to the system? Going back to the old Qtec 550 will work for me :P

    alright 12v pin in, didnt do any good, probably made it worse.. my screen jittered upon startup which was the sign of the power going bad (which was happening before the system halt before). Replaced it back with my beloved old Qtec   everything working fine and back to normal.
    I may note that while taking both results the 12v pin was not used.
    The antec would not give enough power somewhere resulting in a halt, probably to the video card or something. I'll stick with my Q-tec for now and install this video card and see what happens, I've removed one CD drive (which wasnt working anyway) lets hope that can compensate for the extra current needed?
    The new video card is the MSI 59000xt Vtd-128 Btw

  • Finder crashes with External Drive on Sleep Mode

    I purchased my new iMac 21,5" less than a week ago, and I haven't had a problem with it except for one that it's been bugging me a lot.
    I have a LaCie 1TB Quadra d2 external drive that I use to store footage (since it's HD, the filesize won't fit in my 500TB internal hard drive), but I noticed that sometimes when LaCie external drive enters in Sleep Mode, the Finder freezes and the only two ways around this, is to force reboot, because the Finder won't answer and won't open again, or unplugging the external drive without ejecting him first, which it's not safe for me to do, because I'm afraid of hurting the device, and the files in it are pretty important.
    This happens almost everytime, especially after a long time on sleep mode. I usually leave Final Cut Pro transferring files all night (since it takes a long time) so I kinda need the sleep mode, but when I wake up, Finder and Final Cut Pro won't answer.
    I updated to Snow Leopard 10.6.8 on day one. Is there a way to fix this? Is it normal? I read somewhere that some users were having trouble with external drives on Sleep Mode, but I can't seem to find any further information about this problem.
    Thanks!

    I've got a MacBook Pro 13.3" that's a little over a month old, with a LaCie 1TB LaCie d2 Quadra with USB 3.0, #301542U and I'm suffering the same problems and a few others with it. I've got a partition on it set up as my Time Machine backup drive. I've turned off the Put the hard disk(s) to sleep when possible in the Energy Saver preferences but I'm still having the sleep problem with it. According to the LaCie Manual:
    By default, your drive will enter Eco Mode after 30 minutes of inactivity in order to conserve energy. To exit Eco Mode, simply access data on the drive and the disk will automatically restart. You can manage this feature using LaCie Desktop Manager. Click the Eco tab.
    The LaCie Desktop Manager (in my case) only takes me to the Energy Saver Preferences in OS X to adjust the time there. Turning off Put the hard disk(s) to sleep when possible doesn't seem to make any difference, the drive still goes to sleep after 30 minutes. However, after 15 minutes the drive seems to wake back up, but then during the next 15 minutes goes comatose (no power light). Sometimes it will go through multiples of these sleep wake cycles without going into a coma, but eventually it does go into a coma. This happens in between hourly Time Machine backups.
    After locking up Finder, Disk Utility and Time Machine multiple times trying to access the drive in this state I figured out that I could cycle the power switch to regain use of it (with a Finder warning of course) but this will only lead to file corruption eventually and I shouldn't have to resort to this. I've also dismounted it, expecting it to turn off and instead it goes into an extended spin down cycle (rapidly flashing light) and never turns off (or goes to sleep or what ever it's supposed to do) and once again requires turning the power switch off.
    This is just too unpredictible and unrelable for me and as soon as I get the opportunity to do a 7 pass erase I'll be returning to the place of purchase. Based on the reviews of other external hard drives a drive from another company doesn't look to be much better of a prospect so I'm not sure what I'm going to do.

  • Serious problems after Mavericks installation with External Drive Lacie P9220.

    Experiencing serious problems after Mavericks installation with External Drive Lacie P9220 1TB. Mac Finder totally locked!
    I had to format the External hard drive with a Windows PC (fat32), then format again with my IMac (mac Journal.) and hopefully restored data from time machine backup.
    So far so good but system looks unstable. Some software were not able to write on the hard drive.Some strange things happens. With Mountain Lion never had an even minor issue.
    I read many discussion regarding problems with WD, just wondering if anyone had the same problems with Lacie and if there is any tip to solve the
    problem.
    Many thanks.
    Marco

    Thanks very much for your reply.
    Unfortunately I couldn't find a solution because the article refers to whom have configured the drive with included software and drivers that came with the drive.
    This is not my case, I never used any third party soft ...only OS X disk utility ...

  • IMac won't boot with external drives attached

    I am using iMac 27" Late 2013 model upgraded to mavericks 10.9.4. Two external drives are always attached with it, one is segate 3.5" 2TB USB 3.0 drive and another one is 2.5" usb 2.0 drive.
    when i start my imac with external drives attached it won't boot up. Stuck at plain white screen after a startup chime, not even any apple logo or any progress circle appears. And i have to detach all of my drives to make it boot.
    This problem arises after upgrading to mavericks. Already tried resetting PRAM, SMC and checked Startup disk and verify disk with disk utility.

    Raja,
    Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • ITunes hangs with external drives; Genius is totally impossible to setup

    iTunes very frequently hangs when I am using tracks on my external hard drive. I have verified the correct xml of the library files, and the drive's permissions are good. I also recently defragged it. However, oftentimes if I am editing the tags on or simply playing a track, the beach ball comes up and does not go away. When I force quit, I cannot reboot iTunes because it remains in the dock, with an arrow under it, even though it no longer is running.
    After much trial, error, and grief, I found that when I physically disconnect the firewire drive (improperly, as it's still running, and won't eject due to having its files allegedly in use), the hang magically goes away. I can then sometimes replug it back in and work again, at least until iTunes hangs once more. I am sure this is not good for the drive and its files.
    This did NOT happen under previous versions of iTunes and using previous system versions (I'm on iTunes 8, 10.5.5). It is a VERY. BIG. PROBLEM.
    One of its many effects is that I have not been able to get the Genius function to work on my machine, as it always hangs. The Genius setup is so slow that I've never made it much past the first step. I have an 800GB or so library, and there MUST be a way to get this to work.
    Are there any quick fixes to this drive issue? If not, can Apple PLEASE correct it ASAP? Not everyone has a little bitty iTunes library that fits on the internal disk.

    Bummer that this remains a problem. I suspected it was the external drive I was using and from what I read here it seems confirmed. My library is much smaller that both of the ones listed here so I wonder if it's not so much size but the external drive. I thought maybe I just had a crappy network but iTunes has been uncooperative ever since moving my files to the external drive. And I've only got about 50 gig of files. Well, I guess I don't feel so bad now. But it's still crappy.

  • Managing iTunes with external drive

    I just recently moved my iTunes music folder to an external drive. It's working beautifully.
    It's easy enough to make sure that I have the external drive attached when listening to or importing new music from CD's. However, if I have my iTunes constantly open so that it downloads new podcasts, can I do so without always having the external plugged in and then "consolidate library" to add newly downloaded podcasts to the external?
    Not sure if that makes sense, so let me clarify how I THINK this would work. If my external is plugged in, it will automatically place new podcasts in the music folder on the external. However, what happens if it downloads (or attempts to download) a podcast when the external is not plugged in (but iTunes is running)? Does it then place the podcasts on the internal drive until I later plug in the external? Then I would just have to "consolidate library" to move the newly added to the default external drive?
    Sorry for such a convoluted explanation. Hopefully one of the top gurus understand what I'm trying to say. I know that I've seen it discussed and posted about before, but I can't seem to find the past posts that address this specific question.

    I just do this manually because I'll end up deleting the content from the internal library anyways. You might want to check if consolidate merges content from your internal library /volumes/Macintosh HD/Users/you/Music/iTunes/ to your external library if the external library is selected when you launch iTunes. If that works, then you should be fine; however you would probably want or need to delete the files from your internal anyways. I've always considered consolidate to be a method of bringing referenced files into the library (you have songs that you imported without having the add to library checkbox selected).
    I have been using an external on a machine hooked up to my HDTV for a couple of years and sometimes I need to sync items to that system from the internal or another machine (network). I just keep that library on the external selected and either transfer purchases or copy over a podcast (if I'm using sneaker net) and double click it.
    For example, if I subscribe to something like GROOVELECTRIC, download a podcast, then simply double-click the actual file, it is added into my podcast directory on the external and placed in the correct location in the podcast tree.
    So, if consolidate doesn't do the trick you can try just selecting the files in your library and launching them to have them copied to your external or you can try using the Add to Library function from the file menu. Figuring out a way to delete the files from the internal after merging/importing/consolidating seems to be the last piece I need to work on.
    I haven't revisited this for a while, but I'd like to hear about any trick you come up with.
    You will still need your internal library set up to mirror the podcast subscriptions you have on the external, so a full deletion of that library does not seem to be the solution.
    Good Luck,
    -j

  • Best practices with external drives connected to Time Capsule?

    I'm enjoying my new MBP but the storage limitations are a challenge with twenty+ years of data. I know it's not technically sanctioned by Apple but in another forum I found a discussion about successfully connecting an external drive to the Time Capsule. I tried this for a few months and had some problems, so I wonder if anyone here might have some insight into which of my drives would be best to use in this way and what, if anything, I must do to bless it for the task.
    The drive most highly recommended in the forums at the time is the WD My Book. After buying it I learned that is Windows users install a package and update the driver for use with Time Machine, which Mac users are not able to do. The driver is available on the web but it's said to cause problems with Mountain Lion, which I can confirm. It's USB 3.0 and powered, though, which my two alternatives are not. It's also 2 TB and presently in two partitions. I also have a Seagate Free Agent GoFlex 500 which gets extremely hot with any use and an Iomega eGo Helium 500 I've been using for backups. Both are USB 2.0.
    My goal is to put my iTunes Library and Time Capsule on the net (running  2.4 Ghz and 5 Ghz, averages 50Mbs). When I did this for a few months with the WD both its shares frequently dropped off my Desktop, as if powered down or something. Also there were the issues with Time Machine many others are having. Right now our video collection sits on the Time Capsule. Would it make sense to move our video to the WD and run iTunes and Time Machine on it? If so, do you have any tips for formatting, petitioning, or drivers (or anything else) to help this run smoothly? The WD works fine when hard-wired and the TC, too is fine without the WD at the party.
    With apologies for the tome.

    Thanks, but the drive is connected directly to the back of the Time Capsule by an ethernet cable.
    Ah, that's a different colored horse.   
    You have a NAS (Network Attached Storage) drive, not a USB external drive connected to the USB port.
    Many of those need software/firmware updates to work with Lion.  Check with Iomega.

  • PC to Mac with external drive as main library

    I recently switched from PC (Dell Inspiron) to Mac (MacBook) and am having some serious difficulties getting my iTunes to cooperate.
    I used an external drive as my main iTunes library on my PC. I would like to continue doing this with my new Mac because my library is quite large. I know it is not as simple as pointing to the folder on the external HD from within the Mac. I have read all the posts out there and none of the address my issue specifically.
    To reiterate, I currently am using an external HD with my PC that contains my iTunes library. I am now using my Macbook as my main computer and want to continue using the same external drive because my library is too large to import to the internal HD. How do I get the iTunes on my MacBook to read (point to?) the external drive where all of my media (music, podcasts, TV, Movies, Games, etc) reside without losing any information and/or files?
    Please help...thanks!
    Brian

    I pretty much did the same thing (switched from PC to Mac) and had the same issue and this is how I set it:
    go to preferences then click on the advanced tab, then on general
    then for the folder just click 'change' and set it to be what your folder with all your music is on (on the external). I unchecked the 'copy files to itunes music folder...' as well (not sure this is needed, but didn't want to experiment it copying everything again)
    then I went to File > Add to Library, selected the same folder and done. It will take a bit as it goes through the whole library. I guess after this you could go back to preferences and check that copy to itunes folder so any future additions get put on the external.
    I hope that helps.

  • Synchronizing folders with external drives

    I just upgraded to Lightroom 2 and I'm having trouble following the file management workflow that I used to use with Lightroom 1.  Basically what I did before was:
    Import photos to either my internal hard drive or to my external Lightroom drive, depending on whether I was at my desk or out and about.  If I imported them to my internal drive, I'd eventually want to get them onto my external drive when I get to my desk. 
    Run a shell script that rsyncs the internal drive photos to the exact same structure on the external drive.  This effectively merges what I had on my internal drive into my filesystem on my external drive. 
    Then I'd delete my folders from my internal drive, and when Lightroom couldn't find the folders, I'd do the Find Missing Folder thing and point it at the external drive.  It would realize that I have selected a folder that was already in Lightroom, so it basically just re-pointed the missing files that were just copied and everything worked.
    Unfortunately if I try this with Lightroom 2, it says "The selected folder or a folder it contains is already in Lightroom." when I try to locate the missing folder.  And while it is quite true that the folder is already in Lightroom, that folder contains all the images from the deleted folder that I just copied over.  I'm stuck and I basically have ~200 images from various dates that have been interspersed in my Lightroom drive, but Lightroom has no idea that they're there.  I tried running Synchronize Folders on it, but that just made it worse, since it didn't realize the files were duplicates and so now I have two copies of my images.  The old copies are still broken, but they have all my metadata and adjustments.
    Here's a small illustration of what's going on:
    Before:
    ~/Lightroom2009
    1234.dng
    9876.dng
    /Volumes/Lightroom2009
    4567.dng
    5555.dng
    After:
    ~/Lightroomempty
    /Volumes/Lightroom2009
    1234.dng
    4567.dng
    5555.dng
    9876.dng
    Does anybody have a similar workflow to me that actually works?
    Thanks,

    Hi CPMTECH,
    To configure the Windows Time Service on first forest root domain controller
    Log on to the domain controller.
    Type the following command to display the time difference between the local computer and a target computer, and then press ENTER:
    w32tm /stripchart /computer:target/samples:1/dataonly
    Where target specifies the DNS name or IP address of the NTP server that you are comparing the local computer's time against, such as time.windows.com and 1 specifies the number of time samples that will be returned from the target computer. In this example, only one sample will be returned to test basic NTP communication.
    Open UDP port 123 for outgoing traffic if needed.
    Open UDP port 123 (or a different port you have selected) for incoming NTP traffic.
    Type the following command to configure the PDC emulator and then press ENTER:
    w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update
    Peers specifies the list of DNS names and/or IP addresses of the NTP time source that the PDC emulator synchronizes from. For example, you can specify time.windows.com. When specifying multiple peers, use a space as the delimiter and enclose them in quotation marks.

  • Issues with external drive on Mac Mini / Lion

    I'm using an external SATA drive in a Newer Technologies Voyager dock (which I like to call the "toaster") with a brand new Mac Mini i5 2.3G via FW800.
    The drive was formatted using Disk Utility on a G4 running Tiger (10.4.11)
    With the drive mounted, the Mini's performance seems to slow down, and it randomly dismounts the drive, with the usual warning, "you disconnected your drive without dismounting it first, bla bla...)
    I think I remember when Leopard was new, there was a firmware issue that had to be dealt with, and when moving drives from OS 9 to X and back to 9, I lost access to the data on the drive.
    I'm also aware of the partitioning scheme difference when formatting drives for use on the Intel machines.
    Could either of the above have anything to do with the problem I'm having here?

    I'm not an expert in this, but as far as I know, GUID only comes into play if you want to boot from it, but...... you never know, it could - here is an excerpt from Disk Utility:
    If you’ll be using the disk only with Mac computers, choose GUID Partition Table.
    Another thought is: how old is that drive? All hard drives fail sooner or later - have you tried to check it with Disk Utility or something like Disk Warrior?

  • Poor performance with External Drive

    I am using FCE with a 1TB external drive (FW 800) as the scratch and file disk. I have been having some erratic transfer rates to/from the drive during editing sessions, playback within FCE, as well as play back of QT movies generated by FCE.
    I have searched through the forum and really didn't find any thoughts on specific firewire problems of this nature. The drive seems to do fine during some standardized tests and can get up to 50 MB/sec. However, during editing and playback in FCE, sometimes it's that high for bursts, and sometime no transfer for a minute or so. Plays havoc with workflow!
    Do the brilliant minds here have any thoughts/suggestions?! (I've contacted OWC and their recommendation was a new cable; tried and no better performance)
    TIA.

    The problem is you are using the same drive for Time Machine and active storage.
    You should be using a dedicated drive for Time Machine and a separate drive for active uses such as editing with FCE. Even then, you should turn Time Machine OFF while you are working in FCE or iDVD.
    In addition, your system HD is at the point where you need to free up space. According to you it's a 160GB drive and you have about 40GB left. That's about as full as you want to let it get. As it fills up even more your overall system performance will degrade further, esp. if you are doing video.
