Help with New 500GB Hard Drive

I'm going to buy an additional internal Hitachi HD for my mac. In my system profiler it says I already have a Hitachi HDS725050KLA360, which I have found cheap online. Does any know if the "Revision" number of my HD has anything to do with which HD I buy? Also does anyone have any experience setting up two HD's for RAID 0 for fast performance?...is that just done under the disk utility?

Welcome to the Apple forum's!
RAID 0 will make you G5 a lot faster! The read time is abaut 2x faster, and the write time is a lot faster, but not 2x.
Setting up a RAID 0 is realy easy in disk util, just dragging and dropping the disk's where you like and select RAID 0. Remember that you have to do a fresh install off OSX to let OSX run on a Raid 0 set-up. It will improve the performance a lot!
You can place every Sata HD in your mac Pro. So if you want to make a striped RAID, then you can also use for example a Hitatchi and a Maxtor together. As long the size's are the same.
Just like the other poster said, it is important to make back-ups's when you use a striped RAID. Because if one HD crashes, you will lose all the data on both HD's.
If you can get exactely the same HD, but only another rev., then that would work perfect.

  • MacBook Pro Retina with a 500gb hard drive - 400gb storage space?

    I have a MacBook Pro Retina with a 500gb hard drive. I recently deleted a windows 8 partition, and now my macbook says its total storage capacity is 399.42gb. Is this normal? Or am I missing 100gb storage space?
    When I deleted the partition through boot camp, there was an error, but the boot camp partition seemed to have been deleted completely. I ran disk utility repair and single user mode command prompt /sbin/fsck -fy to make sure my disk was properly partitioned, but it still shows 399.42gb total storage in my "About This Mac".

    You did not remove your Windows partition correctly. You need to remove it using Boot Camp Assistant. If you cannot then you will need to repartition the entire drive back to a single partition/volume.

    Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575
    You can buy Snow Leopard at:
    Snow Leopard disc source - http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
    You could contact Apple Support and see if they have the original discs for that machine but it would be 10.4.11 and there's no reason not to go to at least Snow Leopard, especially since the 10.6 discs would probably cost the same as a replacement set of 10.4.11

  • Help with using external hard drive to boot windows on PC

    Hi,
    I'm not sure if this is in the right place, so apologies in advance if not. I've looked around the internet for a good while now, and I haven't found anyone in my exact position.
    My PC's hard drive (running Windows 7) recently died; long story short, I am attempting to reinstall windows. The only other computer I have is this MacBook Pro, on which I have an .iso file of Windows 7. So I want to use my external hard drive (WD 500GB "MyBook") as a boot device so that I can install Windows onto my new internal hard drive.
    The problem I am having is that, well, nothing seems to be working. Every time I try to load the .iso onto my external hard drive and boot my PC with it, either a blank screen appears or it says "missing operating system".
    I have made sure that the BIOS is running the external hard drive as its boot priority.
    I have tried using Disk Utility to partition the external drive, then using 'Restore' to load the .iso onto the partition, to no avail.
    I have tried simply dropping the extracted .iso files onto the hard drive, this doesn't work.
    I have also tried changing the file system of the external hard drive using the 'Erase' feature (NTFS-3G (using an addon), FAT32, exFAT, all of the others), but I notice that whenever I use Restore after doing this, the file system seems to return to Mac OS Extended, which might be why it isn't booting up on my PC. Is there any way I can succesfully partition the external hard drive in a format that will allow Windows 7 to boot (such as NTFS?), and is Disk Utility even the right program to do this?
    If you want any more information from me, please let me know and I'll do my best to provide it - I'm not the most advanced mac user in the world, but I've spent days trying to fix this problem and nothing, no combination of anything, seems to work at all. So any help will be greatly appreciated!
    Thanks

    Here is a quick suggestion for you:
    Download Virtual Box (free PC Emulator for Mac) and install Windows 7 on your Mac (don't worry about activating it yet, as you don't need to keep it more than a few hours).  You can tell Virtual Box to use the ISO file as the DVD drive for your virtual Windows computer, so no need to burn a disk.
    Search Google for creating a bootable USB installer for Windows 7.  I found a link that gave good instructions on how to do this using DiskPart.
    Follow the instructions to make the bootable USB stick for installing Windows 7 using your virtual machine you created above.
    Use the USB stick to install Windows on your new PC.
    Remove the virtual Windows machine from your Mac.
    Remove Virtual Box from your Mac.
    I found a set of instructions and built an installable USB stick last night that worked great for installing Windows 7 Pro (64 bit) onto my older ThinkPad I had sitting at home.  The USB installer also installs in about half the time as a DVD install.  The only reason I have you create the virtual Windows PC is that all of the instructions for makeing the Windows install USB stick are written assuming that you already have access to a running Windows PC.  By doing this install, you have up to 3 days before you would need to activate it and you can build the installer USB stick and remove teh virtual computer long before that.

  • Help with unreadable external hard drive

    I am having problems with an external hard drive and found your Email in yahoo answers.
    I have a 'MB' external hard drive with a Mac OS X 4 11. A few days ago I turned off the Mac at the back button, after the screen went dark, I unplugged the HD only to find the Mac came on again. The Mac must have been in sleep mode? Since this time the Mac will not recognise the HD.
    I tried another USB, making sure the preferences under finder is checked for all items and tried data recovery, PRAM reset, Disc Utility, which did see the drive (in gray) and it gave me this message; Error; underlying task reported failure on exit / 1 non HFS volume checked / 1 volume could not be repaired because of an error / unable to read FAT (input/output error).
    I am hoping I can still use this external HD or could there be bad news ahead? I have not yet tried this on another Mac. Please can anyone help or advise? Thank you.

    that was my backup!
    If you truly mean a backup then that means you still have the original files on your internal drive, or wherever. You just make another backup. If you mean it was an archive/overflow drive then that's not a backup (and you should start thinking about buying another HD to save both the files on your internal and external since either of those could fail without warning).
    So are you suggesting I go to a place/individual that does PC data retrieval? And does this mean I buy another external HD?
    I don't know much about file recovery on PCs. If this was a Mac drive then there would be a good chance you could either use Disk Utility on your Mac already to repair it, or perhaps a utility such as Diskwarrior ($100) to do the same. That repair could be done pretty much in-place. It's only when a drive is really seriously damaged, in particularly physically, that you need a second HD. Again, this is if you could do this on a Mac.
    There are supposedly Mac based recovery tools that can also recover FAT, but those would likely need a second drive and the results might not be pretty (files, everywhere, maybe without original file names).
    I'd find a buddy with a PC and see if they have something on there that can do it for a cup of coffee.

  • How to Properly Utilize Elements 5 with New External Hard Drive?

    Hello,
    I just bought a new external hard drive, and want to use it the most effective way. Should I leave Elements on my internal drive, then open the folder/photo I want to edit from my external drive? Or, I guess the only other option is to copy Elements onto the External drive. Lastly, another option might be to have a copy of Elements on both drives, but I suspect that this would not be a very feasible way, for sure.
    Thanks for any help,
    Les

    My suggestions are:
    1- keep Photoshop elements installed on the internal hard drive as it is now
    If you have photo files cataloged in the Elements Organizer
    2- determine which drive letter you want to assign to this external drive. Use Windows Administrative Tasks to set that drive letter so it remains the same. (some people use a letter further in to the alphabet to make it easier to avoid conflicts)
    3- look at this FAQ which will point you to an Adobe techdoc on moving the photo files to a different hard drive using the PSE 5 Organizer -
    http://www.adobeforums.com/cgi-bin/webx/.3bc254a8
    4- I would keep the Elements Catalog and related files in their default location - which is probably their current location. If you wish that can be changed later.

  • Transfer iPod Touch Apps with new main hard drive on Windows PC

    Replacing main hard drive, which hosted iTunes account.
    For songs, I have already saved to 4 DVD's.
    For iTunes, a new main hard drive will look like a new PC, I'd think. Should I de-authorize my account on the current PC/drive before installing new hard drive? Then download iTunes and set up under previous email & PW?
    Other content?
    For photos and MS Outlook contacts, I can re-link to restored data.
    How about downloaded and purchased Apps? Will they survive on the Touch or need I take further action on the PC?
    Thanks!

    Make sure your new computer is authorized in iTunes. Disable autosync in itunes, connect your ipod, right click on it in the device list and choose backup.
    This will save data, pictures and settings to itunes. See what's included in this backup here: http://support.apple.com/kb/HT1766
    Transfer your purchases the same way to copy all apps and bought media from the Store to your computer.
    Set up at least one contact and event on your computer to be able the merge your calendars and contacts after your ipod got wiped during the first sync.
    The rest of the data can be restored from the backup you made.

  • Hi i bought a new 500gb hard drive on my 2011 macbook pro, it is a blank hardrive and i forgot to save my other files on an external hard drive , i have a usb stick with mavericks installed on it. can i just go ahead and do a straight install by using it?

    hi i have a macbook pro 2011 model, i decided to upgrade my hardrive and bought a 500gb blank hardrive, my query is because i wasnt able to save most of my files and my operating system to an external hard drive, i have a usb stick with a mavericks os installed on it. will i be able to do a straight install by just doing this method? i will be grateful for any tips or help u might offer, thanks.

    Is it just bootable or does it have the Mavericks installation files on it? If so, yes. If not, no. You might consider getting an external enclosure. Put your old drive in it and boot to its Recovery partition. You can install from there. As a matter of fact, you can run Migration Assistant and get all your stuff over too.

  • Help with my Internal Hard Drive!!! New to Mac

    Hello! I've only had my iMac for a few months now after switching from PC. I have a 1TB hard drive, which is plenty for my files and photos.
    It says that I only have 244 GB left on my internal. I don't know how this could be. I checked in all the folders that I have, music, pictures, documents, desktop, etc, all the file sizes add up to about 350 GB. What else is being stored in there? I tried to download Adobe Acrobat and it told me I didn't have enough space. What? how can this be?
    Do all my software and applications get stored on there too? I run Adobe Photoshop CS5 and Lightroom. I'm sorry if this is a stupid and obvious question. I'm not very mac literate yet.
    Thanks

    Yes, your entire system including applications is on that drive.
    To see where all the space is going, try Omnidisksweeper (free) http://www.omnigroup.com/products/omnidisksweeper/
    If there's excessive space being used by cache files or other background processes, come back to the forum and and someone will point you to a solution.
    Even if there is "only" 244GB available Acrobat should not be complaining. (But then, it is Adobe) I'd ask Adobe themselves about that one.

  • Help with using multiple hard drives

    Is there a way to install the OS on an "external" (expresscard SSD) drive, but have all of the library and data files on the primary hard disk? I LOVE the speed on my SSD, but it's a pain finding stuff now. Is this something a RAID configuration could help with?

    I have a 1 TB hard drive; but I have a 500GB and 250GB usb external hard drives.
    Wouldn't it be cool if I could make the two external hard drives a RAID drive and use Time Machine to use all the 750GB of external memory to do my backups???
    You can, but I would +*strongly recommend against+* it. See +Concatenated RAID+ in the Help for Disk Utility.
    There are several potential problems:
    Depending on how much data is on your 1 TB drive, 750 GB may not be enough to back it up. See #1 in Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of this forum).
    To set up a +Concatenated RAID+ set, both drives will be erased.
    When (not if) either drive fails, you'll lose all the data on both.
    Both drives must be connected any time you do a backup or want to browse your backups.
    Especially with USB, if one drive wakes from sleep, or spins up, quickly enough, but the other one doesn't, the backup may fail and/or your backups may be corrupted.
    For now, it looks like my only solution is to go buy a bigger external hard drive and spend more money,,,
    That's your best solution +*by far.+* Anything else is taking a large risk with your backups.

  • Fan Speeds, and Mirror Raid with New Internal Hard Drive

    Regards,
    I recently installed and formatted a new hard drive in my PowerMac dual 2.3 ghz computer and I have a few questions.
    1. Now that there are two hard drives do I need to do anything to ensure that the fan on my computer can keep them cool? I think the fans I have in the hard drive bay is enough, but I do not know if they will automatically set themselves to run properly. I can monitor the fan speeds and temp from iStat pro, but do not remember what level the temperature was before installing the new one.
    2. Given that my new drive is a SeaDisc hard drive and the older one is a Western Digital, will this cause any problems in creating a mirrored RAID. I believe that both are 7200rpm drives, and my second hard drive is a little larger (I will just have unused space after making the RAID). I am concerned with the fact that these two drives are from two different manufactures. Will this cause problems or drastically slow down the reading and writing of data? Has anyone else experienced problems in making a mirrored RAID from two hard drives that are not exact matches, and even come from different manufacturers?
    Any advice will help.
    Thanks
    earpshmael

    Hi earpshmael;
    Generally when creating RAID arrays the more similar the drive the less problems you tend to have.
    The real question is exactly why do you want or need RAID?
    I think so many people seem to think that RAID will solve all of their problem. I hate to tell you the bad news but it will not.
    Generally there are to varieties of RAID available using the software RAID built into OS X which are 0 and 1. RAID 0 or stripling is generally for moving large file rapidly for applications like HD video. It usually doesn't help the OS. RAID 1 or mirroring is for protection from drive failure. It is not a valid backup solution.

  • Help With A Full Hard Drive Partition

    I'm hoping someone can help as I've searched previous threads but not found the total answer I need. I have a large external drive that is partitioned. I have completely filled one partition with itunes music and would like to create a second itunes music folder within another partition on the same drive. My goal is to synch both music folders with my 80GB Ipod. Many thanks for your time. BTW I'm using Windows XP.

    Thanks very much Toons for the response. Let me make sure I understand correctly. In addition to unchecking the "copy files to Itunes Music Folder ..." option, should I change the Music Folder location to a new one within the empty partition on my hard drive? Since the current music file is located within a drive partition that is full, where will the new music I add be stored without my creating a new folder in another partition that has empty storage space?
    Thanks again for your valuable assistance.

  • Need help with Raid 1 hard-drive replacement

    Hello All - I hope someone can help with this.
    I have a Raid 1 set-up using two 1Tb external drives (1 Seagate and 1 Lacie) which has been working perfectly - until yesterday that is. I received an error message saying the Raid 1 Set was degraded. On checking I got an error message against the Lacie HDD 'Disk failure'. Following instructions i found on Apple Support i tried to replace the failed drive with a new 1Tb drive - but then got an error message saying that the new drive was too small - on checking the original Seagate Drive reads as 999.86 Gb with the new Drive reading 999.83 Gb. I presume this is to do with formatting of the 2 drives, although one would assume (perhaps naively that as both drives are 1Tb they would be the same size when formatted!!
    In light of this I ran 'verify disk' on the Raid 1 Set and this was ok and I am now attempting to rebuild the failed Lacie drive - 10 hours still to go. However even if this works I would want to replace this disk as it is quite old now. The Raid 1 Set is backed up to Time Machine on a separate HDD.
    Can anyone suggest a way forward for me to swap out the old drive and replace it with the new drive that I have purchased - I can't see how exchanging this for another make would be any guarantee that the disk would be the same size? I understand that I can't replace the failed drive with a larger drive. The only other way I can see of proceeding is to buy a second new disk (same as I got today) and create a new Raid 1 set and copy everything across.
    Thanks in Advance

    For an external hard disk drive or other (different) system shared
    storage devices to work, they probably should be formatted in a
    format seen by both operating systems.
    If the WD unit is not seen by Windows computers on your network,
    the WD may have been formatted in HFS+ for the Macintosh. That
    is OK unless you need a Windows computer to access the same.
    The Macintosh can see and use a standard Windows disc format;
    so the external drive may need to be reformatted away from HFS+
    if that is really what is going on (and archive any data on the suspect
    drive elsewhere, since it will be lost to reformatting overwrites)
    and then both Mac OS X and Windows should see the files on there.
    And Macs set up to run Windows may also see the non-Mac format;
    without having to re-boot via BootCamp, if that option is in use.
    As to the other question(s) I really have no idea at this point in time.
    And since that may be the rub, hopefully someone will follow up here.
    Good luck & happy computing!

  • Trouble with new internal hard drive

    I just installed an new 300gig Maxtor interal drive (2nd drive). The computer is able to read and recognize the drive, however, I have issues transferring files. For instance when I try to transfer 1 gig of files to the new drive, from my external Lacie via firewire 800, it will say the transfer time is 11 hours. I know that's not right. When I restart, the computer will display a blue screen with a planet earth icon, after a few minutes a blinking folder with a question mark will appear. After another few minutes the apple screen will appear and the computer will start to get up to speed after about 10 minutes. Earlier today when I restarted, the fan sounded like a jet engine. I've had the "jet engine" issue before and was able to fix it. But now it's back. Basically after installing the new harddrive the computer is not the same. Any help would be appreciated. Thanks.

    I have the same computer and am having an issue that may be related. After 5 days of troubleshooting with AppleCare without a resolution, I happened to notice something regarding the hard drive setup through Disk Utility that may be significant. Unfortunately, Apple tech support is closed. I am not a trained technician. Before I say what I observed, can someone knowledgeable let me know what the settings should be on the two hard drives when one is the startup disk and the other is for storage? I am specifically interested in the Connection Type (Internal, upper or lower) and the Connection ID (Device 0 or 1, etc.) information.

  • Need help with HP dv5 Hard Drive.

    I believe I need to replace my hard drive for my HP dv-5.  What I need to know is can I put in any Sata 2.5HD or does it have to be the Toshiba HD that is currently installed?  I understand there could be issues going with a Western Digital with drivers maybe....???  But from a cost prospective I'm think of going with a much larger capacity HD and maybe going from 5400RPM to 7200RPM.  Currently I have 320GB and I'd love to move up to a 500GB or even a Terabyte.  
    The reason I believe my HD has crash is because when I start up my laptop it asks me to install the OS. I've been having issues with this laptop for some time now, it seems to loop at start up without ever loading.  And now with this OS issue I feel it to be much easier to just purchase and replace the HD.  I also have Windows Vista installed on this laptop which I feel is absolutely awful, I have Windows 7 and would love to be able to install this on my dv-5.  
    Additionally, I have attempted to load Windows 7 from USB flash drive onto this current dv-5 and it fails.
    If anyone has any comments or suggestions, has anyone done this successfully...???
    Any help with this would be greatly appreciated and thank you in advance.
    Thanks,
    -Scott

    1TB drive will be too thick and will not fit in the drive bay, any size below that is OK, I suggest the Western Digital Scorpio Black Series 7200rpm drives.
