Question re X220 Hard Drive Options

I had to buy the X220 with a 320GB 5400 RPM hard drive to speed up delivery but really want a 7200 RPM 320GB drive.
I see two possible 7mm options.
Hitachi Z7K320 (HTS723232A7A364)
http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=7031179&SRCCODE=PRICEGRAB...
- Is this the Hitachi that ships in the X220 when purchasing the 320GB 7200 RPM drive?
- Impossible to find in Canada.
Seagate ST320LT007 (listed on seagate.com) or ST320LT023 (model most vendors sell, but no on seagate.com)
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148745
- Cant tell the difference between the 007 and 023 models.
- Seagate only lists the ST320LT007 on their site.  Vendors only sell the ST320LT023 model.  Are they the same?
- Anybody tried the ST320LT023?  Can find this model here in Canada.

If I were you I'd wait, unless you've got to replace a defective drive.
They're milking the situation big time. Seagate for example has not been affected by the flooding, yet is charging the same prices as WD who has been.
Only Hitachi makes the slim drive needed for the X220.
Tiger Direct currentlyt has it in stock for $100, which isn't so terrible.

    Restart with the Option key held down.
    If the internal drive shows up, it's the PRAM battery.
    If it doesn't, insert a compatible Mac OS 9 or X install disk, click the button with the circular arrow, and either repair the internal drive or install a new OS on it. If it doesn't show up in Disk First Aid(9) or the Disk Utility(X), it's either not plugged in or needs to be replaced.

  • HP Pavilion dv6-6c53cl Notebook - Internal Hard Drive Options

    Greetings,
    I just purchased an HP Pavilion dv6-6c53cl Entertainment Notebook PC (at Costco), and so far it's been a great deal. Everything seems to be working just fine.
    Because I do a lot of development work in Virtual Images, I have been running a number of external Hard Drivers from the notebook over the couple of weeks since I've owned it (including an external SSD). All that seems to work fine.
    But, I was wondering if anyone knows whether it is possible to install a second Hard Drive or SSD in this Notebook Model. I saw on the HP site that some Notebooks allow the installation of a second Hard Drive, but I couldn't find any information on this model that would suggest it can handle such a configuration.
    My primary objective for doing this would be to retain the original 1TB Hard Drive that came with the Notebook, but have a secondary SSD Drive to perhaps run the Paging activity from, when such functionality is needed upon running some of my larger Virtual Images.
    Any assistance with clarifying if this is an option with the HP Pavilion dv6-6c53cl would be very much appreciated.
    Cheers,
    Wayne

  • IMac DV SE 400 chimes, gives flashing question mark. Hard drive bad?

    My G3 iMac DV SE 400 will not start up. This is what happens:
    1. Startup chime
    2. Hard drive starts to spin
    3. Hard drive "clicks" once
    4. Flashing question mark on screen
    I tried resetting the PRAM and disconnecting everything like it says in the manual. I have booted up from CD and used Disk Utility (OS X) and Disk First Aid (OS 9) to find out if the computer "sees" the hard drive. No luck with either one - the drive does not mount. I have also tried System Profiler and the computer does not recognize the presence of any hard drive there either.
    Is the hard drive really "dead?" Can it be resurrected - at least to the point where I can retrieve my files, pictures, etc.? I'm confident that the drive is receiving power because it actually starts to spin up (see #2 above). Am I overlooking something easy here? Could it be as simple as replacing the battery? I haven't tried that because the hard drive does "attempt" to start up.
    Failing all else, is it possible to retrieve the data using my other Mac even though the hard drive will not boot?
    Any help would be appreciated. Thanks.

    Well if it spins up you might be able to salvage your data with Data Rescue II (free demo) or Disk Warrior. You could also try Target mode but if disk utility didn't see it then that's probably not going to be any better.
    If those two don't see it then your only option is data retrieval via a pro company but that will be very expensive.

  • Flashing Question mark: New hard drive not working Macbook Pro late 2008

    After following several peoples advice on this forum I decided to upgrade my Macbook Pro late 2008 with a Seagate (1TB) Solid State Hybrid Drive 2.5 inch.
    Heres the device.
    http://www.morecomputers.com/spec.aspx?pn=ST1000LM014
    After creating a mountable boot on a External hard drive with Mavericks install I removed the current hard drive and replaced with the new seagate drive. However it didn't seem to recognize the external hard drive (it is quite old but works perfectly) and went to a flashing grey question mark screen and wouldnt do anything else. Ive tried holding down command-r and option-r but I get nothing. Its just the same flashing question mark. I have done this several times and the same result.
    I put the old drive back in and it works fine.
    I am trying to work out is the problem with the mountable external hard drive OR is it the hard drive is not compatible with my computer?
    Appreciate your help
    Gary

    Sorry I think you may be confused.
    I am trying to install the new Seagate hard drive to my mac (not as an external hard drive).
    I replace the macbook pro hard drive with the seagate drive:
    http://www.morecomputers.com/spec.aspx?pn=ST1000LM014
    I then started up the machine with a usb external hard drive with a boot copy of mavericks on it. However, it just displayed a flashing question mark and wouldnt start booting the osx.
    I am trying to work out is the problem with the mountable external hard drive OR is it the hard drive is not compatible with my computer? Im guessing it must be hard drive. Would it be better to use a USB pen drive as the external hard drive is quite old?
    Does anyone know what the problem could be as the hard drive is brand new.
    Appreciate your help
    Thanks, Gary

  • Folder with Question Mark Icon--hard drive kaput?

    Hello,
    I know there's extensive info on this occurring at startup but I wanted to ask anyone a couple of specifics. 
    1). My imac is old.  It's from 2007 and while I've enjoyed it etc., I understand that it's time has "probably come".
    2). No and this is my bad; I've not backed it up.  Luckily, there honestly isn't a ton of irreplaceable stuff on it so in worst case scenario it's not a disaster.  It's more of a nuisance. 
    3). I used OSX Leopard. 
    So here's the meat and potatoes.   Whether its coincidental or causal, I can't say but after I upgraded my iPhone to iOS7, I started to get a couple of "can't connect to iTunes" errors and then suddenly my imac shut down and when I tried to restart, I'd get the grey screen with the ? folder. 
    I'm not a techie but I tried the gamut of troubleshooting fixes.   In short,
    1) I tried rebooting after unplugging peripherals.
    2). I tried rebooting while holding the Option key. 
    3). I tried inserting the OSX install disc and restarting while holding down C.  The computer merely ejected the disc.
    4). I tried resetting PRAM
    On all attempts, the folder icon reappeared.  I cannot get any kind of disk utilities tools to open.  I cannot get past the folder icon. 
    I went to the Genius Bar this AM.  The techie ran a diagnostic and concluded that my hard drive was dead and that he cold not help me anymore because the machine was too old.  He couldn't/wouldn't give me any details presumably because apple has no interest in servicing/dealing with an old machine. All he would say to me is try an authorized reseller. 
    My experiences with Genius Bar are routinely unpleasant so I can't tell if this guy was truthful. 
    My questions:
    1). Is there another fix I can attempt to get the imac to reboot?  If I can get one reboot, I'll go immediately back up everything. 
    2). Does this sound like a hard drive death?
    3). Are my data lost forever?  
    Thanks!

    I tried rebooting while holding the Option key.
    If the startup disk is not available from the Startup Manager window, that's an indication that the disk has failed 
    Genius Bar was most likely correct.

  • Folder with Question Mark, Clicking hard drive and unformatted status on the hard drive in DU

    Hi.
    We have a mac Mini 2012. Only 6 months old and has been used as a media server for the entire 6 months.
    All of a sudden the mac will not work as usual.
    When it starts up there is a clicking sound, almost like a clock, then a white screen with a flashing Folder and Question mark.
    I have used every startup key combination possible. I've even tried to boot in target mode with my Macbook Pro to see if I can access the files on the drive but had no luck.
    I can only boot from the internet download OSX. I tried to install Mountain Lion again but there was no destination to install it to. When I go into disk utilities the drive is shown as a TOSHIBA (Blah Blah blah). Macintosh HD is not shown.
    The drive has no verify or repair options and is classed as unformatted.
    I decided to try and erase it and reformat it but it gave me this error "unable to write to the last block of the device"
    I'm pretty sure I know the answer to this but I'm gonna ask anyway.
    "Are the files recoverable?"
    and what the F do I do?

    No, no backups, this was the backup for my laptop which was failing as well. I moved all my media and files across to the mini, deleted them on my laptop and had the mini work as a media server as well as a back up location for the files that were still on my laptop (mainly photography work)
    I guess I'll have to take it back in store for the hard drive to be replaced as it's still under waranty.
    Does apple give you the failed hard drive back? we have lots of bank statements/bills/passwords and all manner of personal data stored on it. I don't want it falling into the wrong hands.

  • A simple question about external hard drives.

    hi. this may be a stupid question but i kinda need to know the answer.
    can you use any external hard drive on a mac mini?
    also does the mac mini come with a wireless card?

    Welcome to Apple Discussions!
    can you use any external hard drive on a mac mini?
    Nearly any, but not necessarily all. Some bus-powered hard drives will not function at all, or may function inconsistently, and not all external drives will satisfactorily daisy chain, but by and large any mains-powered USB or Firewire drive will work. If intended for use to boot an Intel-based Mac (or to be bootable for such a system in case of problems with the internal), it will need to be partitioned in the GUID scheme (achieved easily via Disk Utility).
    Firewire is better than USB if you have the option, simply because FW is more consistent in data transfer performance. USB drives are typically cheaper if cost is a significant factor.
    In some ways, choice of drive may be affected by intended use. For example, if you intend to boot the system with it, a fast (meaning 7200rpm) drive with Firewire interface would be a good choice, while if being used for storing an iTunes library, a slower 5400 rpm drive with USB2.0 interface would be perfectly adequate.
    also does the mac mini come with a wireless card?
    All current Mac minis come with 'Airport' wifi already installed, though the original entry-level mini did not have wifi as standard. If your mini is one of these earlier ones, wifi can be added in a number of ways. If it's a later model, an Airport icon is normally set to show on the menu bar. It looks like a fan and if switched off, the fan will be blank, in on but not connected to a network, it'll show 4 grey arcs, and if on and connected, the arcs will be black.

  • External Hard Drive Options for Back Up - USB 2.0 or FireWire

    Needing some advice on this one. Looking to purchase an external hard drive for back up through Time Machine - also running Win XP via Parallels. Should I go USB 2.0 or FireWire or have both options? Is there any difference in speed? I will be also using the external hard drive as needed for other manual back ups and data transfers eg movie projects. (and yes the Macbook has Firewire).
    Would appreciate some comment / recommendations.

    Hey Pluke and welcome to the forum -
    Firewire is faster overall for data transfers especially large or lengthy ones. With this in mind, I would use an external enclosure that has both Firewire and USB.
    I'm not sure if this was part of your question or not but I would not include your virtual machine (xp) in your Time Machine backup. The reason is it will fill up your backup drive quickly because your TM backup copies hourly every file that has changes made to it. Your VM file is both large (the size of the virtual drive) and has changes even if you just have it open and not really using it. You should include your VM file in your manual backup instead.

  • Question about replacing hard drive

    Hey everyone. I had a question about replacing a hard drive for a 2012 midyear pro. I have replaced hard drives before on windows machines, but this is the first mac I have owned. It didn't come with a hard drive when I bought it, but I do have mavericks installed on a usb. As far as a new hard drive, will any 2.5 laptop hard drive work? I read it needs to be 9.5mm thick. Is that correct? As far as I am concerned, hardware is hardware and should be the same as replacing a hard drive on a dell laptop but wanted to see if apple has any weird restrictions.
    Also, is there anything I need to consider or be aware of when putting in a new hard drive? Or can I just hook up the hard drive and plug in the USB and install the software onto the hard drive. Thanks
    Excuse and ny ignorance as I am new to macs.

    Yes.  Any SATA drive will do with those specifications.
    Also, is there anything I need to consider or be aware of when putting in a new hard drive? Or can I just hook up the hard drive and plug in the USB and install the software onto the hard drive.
    Assuming that the installer is functioning correctly, install the HDD in the MBP and engage the installer.  You should come across a 4 option menu.  Select Disk Utility from it.  Open Disk Utility>Erase and format the HDD to Mac OS Extended (Journlaled).  One you finish that, you may install the OSX.
    Ciao.

  • How to partition x220 hard drive?

    Greetings. I need to partition my new x220's hard drive. But something prevents me to do so. Maybe the bios? I took out the hard drive and partitioned it as an external drive through my other computer but this time the x220 did not recognize the drive and I had to reinstall windows from recovery DVDs. I would be greatful if you could help. 

    hey histor,
    when you tried to partition the hard drive, what was error and what did you use to partition ?
    Was it a third party software or was it the built-in Windows Disk Management ?

  • Questions on heat, hard drive, graphics 1.5GHz

    I am considering a new Powerbook 12 inch to replace the 15 inch TiBook I just traded in at Powermax -- stretching the budget to the current 15 is tough, especially when there still seem to be at least some firmware questions if not hardware -- and the small 12 is tempting. Whatever it is, it has to be a Mac, and due to monitor spanning, it has to be a Powerbook.
    So some questions.
    How is the 12 inch these days for heat? Obviously heavy hard drive activity (such as all the demos they run on it in the Apple Store) will heat up the left side wrist rest given where the hard drive is, but how is it for typing on in actual day-to-day use?
    Anyone tried the 100GB 5400RPM BTO? Of course the 80GB 5400 is standard, but is there any significant speed difference between the two (denser platters usually mean faster transfers).
    How about the Nvidia 5200 graphics card? Any bottlenecks I should be aware of compared to a Radeon 9550/9600/9700?
    And, any difference in durability compared to the 15?
    Lastly, how about the display? They seem a bit dim in the store, but they also seem like they have a jiggered stock profile. How about when you hardware profile it properly (I have a ColorVision Spyder2Pro)?

    As far as video chipsets go, a 5200 is not going to run with the ATi 9600 or better in terms of fps for the gpu, I'm not sure about the 9550. The 9600XT, and I'm using one in a desktop, roughly runs with the 5700 Ultra and a little behind the 5900 in nvidia's lineup. I'd say as far as notebook gpu's go, all those gpu's are dated and are in need of revising. The 5200 is a couple years old and so are the ATi gpu's, that is for desktops. But when you look @ PB specs, a 9700 128 MB video vs 64 MB FX5200, the 9700 is way ahead.

  • Questions on replacing hard drive in Compaq CQ58 for the experts

    I have a Compaq CQ58-bf9WM, product number: C2M29UA#ABA with Window 8 version 6.2.9200 build 9200. Windows 8 is not meeting my needs and I wish to replace it. My plan is to replace the existing hard disk with a new solid state disk. I need to prepare the new disk for using the UEFI start up process and configure the UEFI BIOS to boot from the new disk. I also plan to place the hard disk with Windows 8 into a USB hard disk adapter. This will allow me to use Windows 8 when I need it by using the UEFI Boot Device menu in the UEFI Start Up Tool(or screen).
    The replacement solid state disk in order to use the UEFI start up process needs to be set with GUID Partition Table (GPT). What Windows 8 tools (e.g. old fdisk Care available to do this and where one can one find instructions for the process? If the tools are missing on this installation of Windows 8 then how can I get the necessary tools?
    According to the HP document, HP Business Notebook Computer EFI Guidelines, the replacement solid state disk there needs to be VFAT32 EFI System Partition (ESP) labeled HP_TOOLS and marked as boot present to support UEFI start up process. Presently, the existing hard drive VFAT32 ESP does not have any label? Do I need the HP_TOOLS label on the new solid state drive?
    On the VFAT32 ESP, there needs to be a directory structure of /BOOT/EFI/ with the EFI programs(boot loader, boot manager, shell, etc.). How can one register the new EFI programs (within/BOOT/EFI) to allow them to be started by UEFI Boot from File menu of the UEFI Start Up Tool?
    The VFAT32 ESP on the existing hard drive has a directory HP in /EFI. The HP directory contains directories BIOS, BIOSUPDATE, and SystemDiags. I am assuming I will need copy this directory structure and their contents to the new solid state drive VFAT32 partition. Is this correct?
    There are also two directories, boot and EFI in the HP directory on the VFAT32. The boot and EFI directories appear to contain Microsoft boot software for Windows 8. I should not need these since Windows 8 will not be on the solid state disk. Is this correct?
    Before I make any changes that affect the BIOS, I would like to make a backup copy of the BIOS and its information. How can I do this? I would also like the backup copy to be stored in the ESP BIOSUPDATE directory.
    I would like to have the UEFI Shell available on both drives(existing and new). UEFI Shell is part of the overall UEFI specification, so it should be able to be supported by the UEFI BIOS. It needs to have a signature or key file to register it. Does HP have a version of the UEFI shell with a signature file available? If yes, then how does one get a copy of files and installation instructions? If no, then how does one install the Intel provided shellx86.efi program (especially the existing drive)?
    Thank you in advance for any help on any these questions.

  • FORMATTING QUESTION NEW INTERNAL HARD DRIVE

    Hello, I have read some similar posts online this morning but I wanted to get some clarity.
    My hard drive failed on my iMac G5 Power PC [1.5 years old!]. Anyway, I took it to the Apple store in Schaumburg and the guy said I would save a lot of $ by buying a hard drive on my own and installing it because it was very simple. He said that when I went to install OSX it would say that the hard drive is not formatted and ask me if I "wanted to format it now?".
    Well that isn't the case. I installed the new hard drive no problems. Very simple. But when I go to install MacOSX it doesn't recognize the hard drive.
    So I ran disk utitlity and the drive shows up there which is good right? I have read similar posts and some say to erase and then partition. I'm just confused. I assume partition means the same as format? I also read posts about picking a volume scheme which I have no idea what that means.
    Thank you in advance for your responses.

    After installing the drive, boot from your install disc, go to Disk Utility and select Partition. Click on “Options” and verify GUID is selected if this is a bootable drive. You can then have either one partition (which means you use the whole drive as one entity), or create two or more partitions according to your need.
    Format the disk as Mac OS extended and you should be in business.
    Please post back,
    Miriam

  • Need help reinstalling Yosemite/Question about external hard drive

    I have an early MacBook Pro and I have to reinstall Yosemite because I've been getting nothing but spinning beach balls, slow loading, lag in type showing up, and wi-fi issues.  I took the laptop to the Genius Bar at the Apple store last week and they ran diagnostics on everything and all was perfectly OK.  No hardware issues, no memory issue and he said my laptop was very clean.  He saw the spinning beach ball many times while he was working on my laptop and suggested that I turn off File Vault as that could be causing the slowdown.  He said if that didn't work (it didn't) to buy an external hard drive (which I received today) and to back up everything through Time Machine then reinstall Yosemite.  I specifically bought an external HD that says "for Mac" and as soon as I connected it Time Machine opened and did the backup.
    Now these are my questions.  Are all my photos on iPhoto, and my Word for Mac documents backed up so that when I reinstall Yosemite, everything is going to be right where I left it?  Will I lose Word for Mac and have to reinstall it?  Isn't Word for Mac a one time use/install and will I have trouble and have to call Microsoft to input my authentication key in again and will they let me? I know silly questions but I'm really worried about losing stuff.
    Also step-by-step detailed instruction on how to reinstall Yosemite would really be appreciated.  Thank you!

    If you have taken the backup using the Time machine then there is nothing to worry as all your photos from iPhotos and Word for mac documents are backup safely by your time machine.
    Only keep one thing in mind that the external HDD which you use for the time machine backup should have the capacity size of about 3-4 times that of your backup data size. Or else, the time machine external drive will start deleting the files if the external drive is about to be full.

    You absolutely don’t have to reinstall the Word for mac if its install in the first place because Time machine will backup the system installed files of your MS Word which you had installed.
    Word for mac is a one time install and you don’t have to call Microsoft for any authentication key after you have restored your Word backup files from the time machine drive. As I said before the time machine will backup your Word system installed files leaving you no chance to reinstall it again.

    Here, Yosemite reinstall procedure......
    Important:    To reinstall OS X, you must be connected to the Internet. Make sure your power adapter is plugged in. Reinstall OS X using the built-in recovery disk.
    In the menu bar, choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command and R keys.
    Select Disk Utility, then click Continue.
    Select your startup disk on the left, then click the Erase tab.
    Choose Mac OS Extended (Journaled) from the Format menu, enter a name, then click Erase.
    Important:    Erasing the disk removes all the information from the disk. Be sure to back up the information you want to keep to an external device. 
    After the disk is erased, choose Disk Utility > Quit Disk Utility.
    Select Reinstall OS X, click Continue, then follow the onscreen instructions.
