Need help controlling external FW drives

I have three external 800 FW drives: one WD and two G-Drives. They are each 1TB in size, and they are daisy-chained. The WD is directly connected to the MacBook Pro. The two G-Drives are chained to the WD. The G-Drive in the middle spins down with a loud click after ten minutes. It is annoying. I have changed my powermanagement plist file with text wrangler so that external disks sleep after 45 minutes. But the middle drive still clicks and spins down after ten minutes, while the last G-Drive on the chain does not. Could this be a problem with the drive itself?

What happens if you use the drives one at a time? Have you tried changing their physical order?

  • Need Help with External Hard drives and too much music

    I am not terribly tech-savvy, and I need your help. I have a G5 PPC dual processor with an internal 250GB drive. I have two seagate firewire/USB2 external hard drives. One is 250GB and one is 350GB. I want to know how to use them to get my Mac to run faster and better.
    My original hard drive is 7GB shy of being full. Almost half of this is my itunes library which is over 100GB. The older (250GB) hard drive has about 150GB of photos/videos.
    My Mac is running slow as molasses and when I power up the external hard drives it slows down to what I recall my original Mac Plus ran like.
    I use the G5 primarily to work with photos, illustrations and creating the occasional DVD with video and photos. the apps I use most often are Photoshop, Illustrator and Painter. I always listen to music while work.
    I hope all of this information is helpful! Here is my question:
    What is the best way for me to set up and use these external hard drives to return my G5 to its original blazing (to me) fast speed?
    PPC G5 Mac OS X (10.4.9)

    I think you should look at adding two 500GB internal drives. I'd say Maxtor MaxLine Pro for cost, but they also run much warmer (43ºC even when nearly doing zilch) so I'd go with WD RE2 500GB for $40 ea. more.
    dump whatever you don't need, trash anything that is hogging space and is just temp file or useless cache. Web browsers can leave behind a ton of small files eating up tens of MBs.
    Use SuperDuper to backup/clone your drive.
    Disk Warrior 4 to repair (after it gets to 15% free, or just forget for now).
    A 250GB drive formats to 240GB and you have ~3% free it looks like.
    For every data drive plan to have two backup drives.
    Keep your boot drive to 40% used.
    And your data drive to 60%.
    Backups can go a little higher.
    Drives are cheap and inexpensive, especially for the space and performance. And they have improved SATA over the years it has been out.
    By doing a backup followed by erasing your drive, and then restoring it, using SuperDuper, which optimizes the organization, skips copying temp files that aren't needed, it also defragments your files. I would do backup daily to different sets that you "rotate." And before any OS update. And do the erase and restore probably every 2 months.
    Make sure you keep one drive partition somewhere that is just your disk utility emergency boot drive that is not a copy of working system, used for doing repairs like running Disk Warrior and Disk Utility.
    You may need to repair; backup; even erase and restore your external drives. Rather than spend on vendor made case, just pick up a good FireWire case either with drive, or bare (and add your own). I think it'd add 500GB FW drive though.
    Why?
    To begin backup of your current drive. To leave your other FW drives "as is" for now.
    Then install a new internal 500GB drive as well so you now have a good current backup, and you have moved your data off 250GB to 500GB. If anything happens, you have one off line FW backup.
    Then begin to clean up, organize, and get your FW drives working. It sure sounds like they have had some directory or file problems.
    You can find a lot of Firewire and SATA drive choices over at OWC:

  • Need help with external hard drive!

    Hi all,
    I have been having trouble with my external hard drive.
    My mac is reading the disk however all my files from the hard drive are missing?
    In disk utility is seems to show that there are files on the disk but I cannot see them?
    At the bottom is shows that there are files on the disk!
    PLEASE HELP!!!!
    Here is a screenshot of my disk utility

    Ok just to clarify the format issue...
    Just move the data from the external drive, format and then move it back if you want, as JiveMasterT explained.
    If the external drive is FAT file system, then you don't need to format the drive unless you are planning on using the drive as an OSX backup.

  • Do you need a special external hard drive for iMac?

    Do you need a special external hard drive for iMac?

    Any external hard drive that will connect via Firewire 800, USB, or Thunderbolt will work.
    I have a 750GB Western Digital Scorpio drive in an OWC case, sitting on a Backpack, which connects via Firewire.  Western Digital Scorpio drives have 5 year warranties, the OWC (macsales.com) cases usually use the Oxford chipset which works well with macs, and the Backpack is a slick way to mount a backup drive without taking up desk space.
    After you hook up whatever external drive you end up with, you'll partition and initialize it for OS X, then begin using it.
    My opinion, I would not get a Western Digital pre-packaged external drive/case.  While the hard drives are OK, there have been a number of people that have had issues with the electronics.

  • Need help buying new hard drive

    I have a macbook that needs a new hard drive and need help knowing what hard drives to buy that will be compatible with it. It is a macbook pro 17inch model no: A1297.
    Any help would be appreciated, Thanks

    Any 2.5" diameter, 9.5mm thick SATA drive will be compatible.  Currently they come up to 1.5 TB in capacity.  I have a 1 TB Seagate SSHD (hybrid) drive installed in my primary MBP.  The cost is a modest premium over a conventional HDD of the same capacity.  Boot and shutdown times are significantly faster when compared to a conventional HDD,  I can recommend this as an option.
    If the bank account permits, an SSD will produce the overall maximum performance gains.  Boot, shutdown and resource hungry applications will be noticeably faster.  Casualyll use such as e-mails and text editing will produce no meaningful performance differences compared to a conventional HDD.
    I am of the opinion that the cost premium is still too high for the benefits that they afford.  Other have different views.
    Ciao.

  • Help/explanation needed - Using an external hard drive

    Hi everyone,
    I bought an external 250gb hard drive as my MBP was very close to full capacity. Yesterday, I had a bit of a scare...
    1. I backed up my Aperture Library onto the external hard drive.
    2. I had about 500 of my favourite images rated 5 star and so I selected these and set up a new project.
    3. I went through my Aperture library deleting folders/projects that I have completed.
    4. I went back into the 5 star ratings and they did not exist. I assume this is because I deleted the master files.
    5. I wanted to have the 5 star images on my laptop and so I connected my external hard drive once again. [This is where I felt I lost control and understanding of what was going on].
    6. I looked for the seperate Aperture files but could only find a file called Aperture Library. I clicked on this but nothing happened at all [I had thought that it would open up Aperture with the previous library].
    7. I dragged the library onto my desktop and waiting for all the images to reload onto my laptop. I then saw that everything was as it was previously, i.e. all the files and images existed. However, my hard drive space was even lower [I assume this was because the current workflow that I had left on the laptop was now duplicated?].
    8. Then I got a message saying my iDisk space is critically low and may damage my Aperture library. Moments later the majority of my images disappeared and a red space appeared where every photo had previously been. Since I have 2 weddings that I am yet to deliver I was very panicked. I tried to drag and drop the Aperture library once again and the message came back that the operation could not be completed due to the current file already existing.
    9. I unplugged the external hard drive and the photos re-appeared [much to my delight]. However, my concern is that I really don't understand what happened and more importantly why. I will need access to the data on the external hard drive in the event in the near future and am worried that the same thing will happen next time I connect it.
    As a result of all this I have some questions, as follows:-
    - Have I adopted the completely wrong approach to backing up data?
    - Can the master files be compressed as I shoot RAW and these are huge files?
    - Why could I not use the Aperture library stored on the external hard drive without downloading it back onto the laptop?
    and a more general question about file storage...
    - I am confused as to how much hard drive space is being used on my MBP. I have 13gb in Aperture, 1gb in iTunes and 1gb in iPhoto. However, I only have 50gb available, so half the capacity is currently being used. I know that Aperture and Garageband applications use about 10gb between them and there is of course the operating system, but 50gb in total seems a lot. On investigation in the finder screen I see that on my personal drive the Aperture, iTunes and iPhoto data is stored there. However, it is also stored under pictures and music respectively. Does this mean that it is storing duplicate copies of this data and that is the explanation for such high hard drive usage? If this is the case, can one be removed?
    I appreciate that this has been a long email, but I felt it was important to illustrate the steps I have taken. As you will no doubt glean from this post I am not the most computer literate person. Any help/explanation would be most appreciated.
    Many thanks,
    Jamie

    Hi Jamie.
    I am not sure what went wrong with your setup but I will let you know my configuration as an example and you can decide if you think it is a good way to have it. I am asuming you are using ver 1.5?
    Like you I have only a Laptop (G4 17" 1.5Ghz 2 Gig Ram - would love a macbook) so hard disk space is a premium. I also have an external firewire drive to hold all the HiRes RAW images. When I download my images from the Camera I do it manually into folders on the external drive (Cataloged by Date and maybe description of location). I then Import the images from those folders into Aperture but use the option when importing to "Store Files - In their current location".
    My Aperture library file is on my laptop so all that it has to store is the "Preview" file that gets generated automatically (in the preferences I have it set up to the resolution of my laptop 1440pix so that if I did a slide show it is only as big as my screen - anything more is a waste of disk space IMO.)
    I do it this way so that it is easy to find and work on my files with other programs such as Photoshop by going straight to the image rather than exporting from Aperture.
    Obviously I cant edit the RAW files while the drive is disconnected but I can still do ratings and keywords without the original files being there.
    I hope this helps.
    Regards

  • New to the forums, not new to Mac. Need help on failing hard drive.

    Hello, glad to have found this forum...I need all the help I can get. Let me explain what I have, what it's doing, what I want it to do, what I "think" I need to do.
    *What I have:*
    733 G4 with superdrive, 512 MB SDRAM, 40 & 60 gig internal original hard drives
    *What it is doing:*
    For about a year one of the drives (seems to be my 60g start-up drive) has made clicking/popping noises not unlike when you click/cluck your tongue. I've ignored it, foolishly, and gone about my business. Then I began having to click the mouse and punch keys when I start-up in order to get the drive to begin spinning, otherwise it would never kick in and I'd get the "?" face. Anyway, I have been living like that for many months until recently when my start-up drive only had about 500MB left of space, I burned some DVD's and freed up about 6 gig on the drive for some cushion the other day. Well, since doing that, when I start up now I get a spinning globe. I have to hold the option key down at boot and then select the drive manually and I'm back to being fine again.
    *What I want it to do:*
    I'm freaked out about losing data because I am a photographer and graphic designer, so I would die if I lost any files. I have been using one of my old iPods as a back up drive to dump data on and burning some DVD's too...but still, I have most of my life still on the drive. Here is what I am considering. I would like to get an external drive to move and continue to grow my massive files for my work and creativity. I'm thinking the G-Tech 320 Quad external would be a good fit. Now, moving back inside, my 60g start-up is telling me it's failing and to back up and replace before...well, you know. My 2nd internal drive is 40g and is strictly my iTunes library of MP3s.
    How do I save myself and replace my start-up drive?
    Do I buy the G-Tech first, move all my files over, then replace the internal, failing 60g? Can I start-up from the G-Tech? Should I/Can I make my 40g the temporary start-up, replace the failing 60g, and go from there? How should I do this and must I get the G-Tech now?
    While on this same question, I am getting conflicting information regarding how much my 733 G4 will recognize as far as each drive size. What is the max size each drive can be? What is the max combined?
    *What I think I should do:*
    I think I should buy the G-Tech, move my life over there, then use the working 40g as my start-up, replace the failing 60g with the largest possible when possible, make the replacement internal the start-up again, use or replace the working/existing 40g as storage/back-up, live happily ever after.
    *And on a side note:*
    I plan to drop two sticks of 512MB memory, this filling it up to it's max 1.5 gig of memory. Will this have a noticeable affect on my computer? If so, how?
    Oh, and the reason I was opting for the Quad G-Tech is because can't I upgrade and add FW800 ports to my G4 rather easily?
    Thank you for any time or effort you give me in helping me through this urgent matter. I had run out of places to go and people to ask before running across this forum.

    First of all I cannot believe you have no backup strategy and only start to worry about it after problems arise. You're an accident waiting to happen. Before you consider anything make backups.
    Basic Backup
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    1. Retrospect Desktop (Commercial - not yet universal binary)
    2. Synchronize! Pro X (Commercial)
    3. Synk (Backup, Standard, or Pro)
    4. Deja Vu (Shareware)
    5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
    6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
    7. SuperDuper! (Commercial)
    The following utilities can also be used for backup, but cannot create bootable clones:
    1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
    2. Toast
    3. Impression
    4. arRSync
    Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
    Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore. Also read How to Back Up and Restore Your Files.
    You can begin addressing the problems with your hard drive(s) after you get your stuff properly backed up. Once that's done get two larger drives for the computer and replace the small ones you now have. Your model should support hard drives up to 128 GBs in size. There is not specific limit on external drives so your external backup drive can be large enough to be partitioned into multiple volumes large enough to backup at least one of the internal drives (using the second internal drive as a backup for the first internal drive. This provides redundancy - an internal and an external backup.) You can then use the additional space on the external drive for your data files.
    BTW, you risk catastrophic data loss by allowing the free space on your startup volume to drop below 3 GBs.

  • Help with external hard drive please????

    I am ready to chuck my computer out of the window I am so frustrated!! I really hope someone can help... Fingers crossed, here goes...
    I have two macs - a MacBook running OSX 4.11 and an iBook G4 running OSX 3.9. I also have an Iomega external hard drive. I reformatted it when I bought it for the MacBook, and have been using it fine.
    Now, I want to move a load of music from my iBook to the external hard drive. But when I plug in the hard drive, the iBook says 'MAC OSX CANNOT READ THE VOLUMES INSERTED' and gives me options of initialize, cancel, or eject.
    I don't want to initialize as I'm assuming this will re-re-format the ex hd and lose the stuff I have on there already.
    Is this the case?
    Why won't the Iomega talk to the iBook? (the Iomega website says macs need no drivers for their products...)
    Can anyone think of any genius ideas for getting the info off the iBook? Bearing in mind that there is no DVD writer, my internet connection is a teeny 2mb/s and the largest alternative storage device I have is a 2 gigabyte photo card (which i have been using, painstakingly, but is causing me massive grief by taking all night to upload from the ibook and then all day to transfer to the hard drive via the macbook, and losing a bunch of files in the process => AAAAAGH!!!!!). I've also tried firewiring the ibook and macbook together but they don't recognise each other. I created a network and accessed the iomega from the ibook via that but the 2mb/s broadband was so slow it would have taken all week, and the machines crashed anyway.
    Thoughts? Ideas? Inspiration? Magic wand????
    THANKS

    Ok, deep breath & relax...
    What format & partition table is the drive in?
    On the macbook with drive installed, Open up Mac HD/Applications/Disk Utility.app
    Select the drive from the list. If the partition scheme is GUID, then 10.3 won't be able to see it.
    & changing requires a reformat of the drive.
    So, what I would do is hold T while booting the macbook until the firewire logo shows on the screen. plug the 2 macs together via firewire 400 cable. your macbook should now show up as a firewire drive on the ibook.
    drag & drop the files you want to move. eject the drive when done & press power on the macbook to exit this mode. press power again to boot.

  • Need help installing my graphics driver in windows vista via boot camp

    New to mac so first time on forum as well.
    Love the Mac but i also want to get on some old games. C&C The First Decade mainly.
    I am currently using below.
    Mac mini Mid 2011 processor 2.5 GHz Intel Core it
    Memory 4 GB 1333 Mhz DDR3
    Graphics AMD Radeon HD 6630M 256 MB
    Software Mac OS X Lion 10.7.5
    Installing windows vista home premium 32 bit
    I have installed windows vista home premium using boot camp assistant and downloaded the windows drivers as well. After i have installed windows i installed boot camp using my Mac OS X snow leopard which installed boot camp 3 or 3.1 i believe and i eventually got apple updates for 3.2 which is what i am now runnning on vista. I had trouble getting my sound to play through my speakers at first but eventually got them working and now it is my graphics driver that i cannot seem to get working. In vista(I also downloaded service pack 1 and 2) when i go to control panel and check out my device control it shows a yellow exclamation point next to the adapter. I guess i need help in getting my graphics installed correctly on my windows. Is there something i should take off to install the correct driver? Or do i just need the correct driver download? If i have the correct driver how do i upload it onto my windows side in the device control.
    When i try to run c&c generals/zero hour i get a directx 8.1 error, red alert 2 is black but i can hear. i know these games can work i installed the graphics correctly the first time when i did not have sound as this is my second time installing windows so the game did load when i did not have sound.
    Advise?
    I was thinking about saying forget this i can't waste hours of my time anymore but i have to be close to getting everything working if i had graphics before and no sound but sound this time and no graphics. I was also thinking about just buying windows 7 home premium sp1 64bit system builder dvd off amazon and reinstalling windows using windows 7 but i want to make sure i can play these games before i spend the money. I thought my mini couldn't support windows vista and if it did only boot camp 4? how am i getting this far to get things to work?
    What is the driver i need to install to get these games working? What do I need to do or what am I missing???
    Do i need to install a different boot camp off apple and find a driver that will get mine to work in vista?
    Any and all responses will be greatly appreciated i have been at this everyday for hours.

    Also is there something, say maybe a driver, that was installed i do not need that is blocking me from installing the correct drivers? What driver in my boot camp folder do i need to install to get to the correct display to run those games.

  • Help with external hard drive connection

    I have two external hard drives. One is connected to my PCMCIA card firewire and the other to the original firewire port. When I get into the final cut pro program, the program shows little red slashes through my different things that I have put into the computer. I need to know how to retrieve those files. The computer does show that the external hard drive is connected, but it shows that the media is offline. I have done this before I just want to know how to reconect the media. I think it should be easy. Please help.

    Have a read of of your Final Cut manuals, Volume IV, Chapter 6, Reconnecting Clips and Offline Media, then experiment with ctrl-clicking the offline files and selecting Reconnect Media.
    If all is well and you have a good naming convention for your clips, a simple search should reconnect everything. If you have changed volume names or have a whole collection of files named 'Untitled Capture' then you may be in more trouble.
