Which types of external hard drives works with T400?

Hi Thank you for reading my post.
Can someone please let me know which types of external hard drives works with a T400?
eSata, USB or firewire?
 Which model and brand you suggest for a 1TB drive?
Thanks 

USB 2.0 is the connection that is natively supported on the T400, no eSATA or Firewire port i think, you can get these ports by buying an expansion card for the card slot (i think it is the expresscard one) on the T400.
Regarding a 1TB drive, most of the large drive manufacturers have one out, but i suggest you unless you need the large capacity, i would stick with a smaller drives like 750 gig or 500 gig since the cost gigabyte is lower. Also i would stay away for storing all your important files solely in these drive, because if these things start to fail it would be on a moment's notice, you probably won't even have time to backup the files, before the harddrive gives up on you.

  • Do all external hard drives work with my macbook pro?

    I just bought an HP Simplesave external hard drive. On the rear of the package, I noticed its compatible with XP, Vista, and 7, but nothing about Mac. I don't want to open it, but I was under the assumption that all external hard drives work on all systems. I didn't think they were operating system specific.
    Anyone know about this specific hard drive, and about hard drives in general if my assumption is correct?

    The drive should work fine once you've reformatted it for the Mac, but whatever small portion of the purchase price went to cover the included software will be wasted, because HP will only have included Windoze software with it. And in the unlikely event that you ever need to call HP tech support, they'll be clueless about anything involving a Mac. These are the two reason why DP suggests avoiding drives whose makers don't mention anything about use with Macs.

  • What External Hard Drives Work With Lion?

    Have installed Lion in my iMac. Need a new external backup hard drive. Understand some hard drives aren't compatible with Lion.  If this is so, can someone recommend an external that is?  The G Drives Mobile works with my Macbook Pro with Lion as OS, but I'm concerned about the iMac.
    Thank you for any response

    I've been using a LaCie d2 Hard Drive Extreme with Triple Interface 250GB since July 2005 (= 6 years) and it still hasn't let me down....yet...
    I only use it a couple of times a week, sometimes once or twice a day, to make complete bootable clones of my HD. For the rest of the time it's disconnected.
    I use Carbon Copy Cloner to make the clones. Mike Bombich, who owns CCC and has an excellent website, advises not to use Western Digital drives.
    As I understand it, this is  because WD drives have something in the software that isn't compatible with the Mac OS.
    I've never heard of there being any particular problems with any other make of external drive.

  • Recently upgraded Mac 24" to Lion (clean install) and now no external hard disks work with Time Machine

    Recently upgraded Mac 24" to Lion (clean install) and now no external hard disks work with Time Machine.
    installed new internal disk first with fresh 10.7.3 Lion software. Also upgrade ram to 4GB. Work great, super fast.
    BUT.... my WD 1TB firewire400 external disks no longer work with the Lion enabled machine now.
    FURTHER... I read somewhere that WD is problematic with Lion but Seagate was not... so I went and bought a new 3TB Seagate GoFlex.
    When it didnt work properly either, I patiently searched and found a software/firward upgrade and applied.
    I re-partitioned disk to extened/journaled standard, etc.
    Then assigned the particition to Time Machine. Drive turned the blue/grey color, so I thought it would work.
    But, it has now been in "preparing" mode in Time Machine for HOURS....
    What is up Apple? So dissappointed. Ive read these type of problems are notorious with Lion and I wish I never upgraded.
    Are you trying to make issues with External disks, to drive people to iCloud?  That trick ont work in me. I will not reward bad behaviour Apple.
    Please provide a fix... I wasted hours/days screwing around with this, instead of using the Mac for what its intended!

    Solved by Pondini, on another thread I opened...
    Answer:
    Sounds like either:
    A directory problem on your internal HD.  Verify your internal HD, and Repair any other volumes being backed-up per #A5 in Time Machine - Troubleshooting.
    Something in OSX may be damaged.  You've tried the "combo," so a fresh copy of OSX (that won't disturb anything else) would be worth a try (and you don't need a tech for that).  See Installing the ''combo'' update and/or Reinstalling OSX.

  • External hard drives work on tiger but not on leopard. WHY?

    My 2 external hard drives worked fine on tiger. I had the backup program and used it every week. Now that I loaded up leopard, I cant see the external hard drives. When I take the drives and plug them to my mac book pro which I have not yet upgraded, they come up fine.
    I cant even see them in disk utility
    Please help

    My external doesn't work either. It seems like it is trying to boot, but doesn't. Meanwhile, the Mac Pro churns and the fan goes into high gear. At that time the screen freezes and the little rainbow wheel just spins. The only way I could get the Mac back was to power down with the power button on the front of the CPU and unplug the external drive. It's just a backup drive but I would like access to it. I'm looking to see if the manufacturer has a patch online, but I'd appreciate any suggestions ion the meantime. I haven't upgraded to Leopard yet on my MacBook Pro, maybe I'll wait a few days... Anyone know what to do?

  • USB 3.0 External hard drive working only as USB 2.0

    Hello all.
    I have a MacBook Pro mid 2012 (specs below) which has two USB 3.0 ports. I have a Kingston USB 3.0 stick and a Toshiba 1TB USB 3.0 external hard drive. With Lion/Mountain Lion/Mavericks, both stick and hard drive worked fine, but since I updated to OS X 10.10 Yosemite, both work as USB 2.0 devices, with slow transfer speed and, in the case of the hard drive, it has a blue/white LED that indicates the mode (blue = USB 3.0 / white = USB 2.0) and it only lights up with white color.
    It's not a device problem, because both work on Windows 8.x machines. I was guessing that it was some kind of firmware or motherboard's usb driver problem but I looked for firmware updates and found nothing.
    Is anyone having issues with USB 3.0 ports? Can you help me with this? Any advice would help.
    Thanks a lot for your patience and help.

    Hi jesusbet,
    Thanks for visiting Apple Support Communities.
    It sounds like the USB 3 ports on your MacBook Pro are not operating at the expected speed.
    The first troubleshooting step I'd suggest in this case is to reset the System Management Controller (SMC) on your MacBook Pro using these instructions:
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
    From:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    If the symptom continues, you can also reset the PRAM:
    OS X Yosemite: Reset your computer’s PRAM
    These two hardware resets can resolve many unexpected behaviors that affect hardware on a Mac.
    All the best,
    Jeremy

  • Is a WD My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive bootable with my Powerbook G4 12" PPC 10.5.8?

    Sirs or madams,
    Is my Powerbook G4 12” PPC 10.5.8 'bootable' with a Western Digital My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive? Western Digital says officially no, but that it MIGHT be. I primarily live in China and bought a datastorage.com.cn Clearlight s400+ external hard drive enclosure with a 320GB disk drive a few years ago in China. My computer 'boots' fine from it, but since I got it in China all the paperwork, etc. is in Chinese; my Chinese isn't quite sufficient enough yet to read it. But there are references to something called "SATA", whatever that is.
    My level of computer 'under the hood' knowledge is extremely low. I've been told that SATA has some relationship as to whether or not an external hard drive will boot a computer via the Firewire connection, something relating to 'interface', which I assume is how separate electronic gadgets work, or don't work, with each other.
    I frankly don't care much for computers, the internet, or their related gadgets such as all these fancy phones. I longingly reminisce about the days when there were no such things. I use a computer & the internet because I have to, and unfortunately unlike a car where one doesn't have to have 'under the hood' knowledge to operate it, just knowledge of the steering wheel, brake, gas, etc., one seemingly must know a ridiculously great amount of 'under the hood' knowledge, including jargon, to operate computers.
    So, please try to respond accordingly; thank you.
    If this particular external hard drive won't, for certain, be bootable with my computer, can you advise as to what readily available brand/model would be in the 3TB range for a similar price, roughly $150ish??
    Thank you very much.

    Mr. BGreg,
    Thank you very much. "...under the covers...". I think you meant "under the hood", as in a car. I suppose "under the covers" would be man/woman interfacing, which I am familiar with!
    Actually, I'm back in the US now for a few months. I looked at the OWC web site, but only cusorily so far. I'll contact them; they appear knowledgeable about Apple computers.
    As to what you wrote about Western Digital's cases, I certainly wouldn't want a poor case. In China I had over time gotten 3 different external drive cases, 3 different Chinese brands, and separately bought Hitachi brand disk drives that 'simply' plugged into the cases. The drives are roughly 80GB 120GB and 320GB. The two larger ones are in cases that have Firewire plugs/jacks, which are bootable with my computer.
    So my understanding, as you wrote, has been that my Powerbook will boot from an external hard drive, provided it connects via Firewire, and the disk drive itself is 'normally' formatted with however my computer's own disk drive is formatted, (HFS OS extended (journaled) or some such??). So I was left wondering why Western Digital would indicate that even though their such-and-so external hard drive case/drive was Firewire capable, that they would then say it would not be bootable with my Apple PPC computer......
    Well, anyway, since you indicated Western Digital's case quality is suspect, then I'll try OWC and disregard Western Digital.
    Naturally, OWC should be able to address this, but your thoughts are also welcome. You mentioned the OWC cases are good with Apples. Would the disk drives OWC supplied with the cases also be of relatively dependable quality?? From my so far only cursory look at their web site they appear to have various options, including case only options where I could insert my own or their own drives. These sorts of options seem preferable, also along with quality components. 
    My Powerbook has been in use since 2004. In China I put in a 1.25 memory 'chip' in the bottom and installed the 10.5.8 operating system, which I understand are the maximum workable with my Powerbook. When I inquired with Chinese friends if my 1.33 GHz processor could be taken out and a more powerful one put in, they said it wasn't feasible because in my particular computer my processor was, as I recall them saying, soldered/'permanently' connected with the 'motherboard', that it would just be easier to get a new computer.
    I would be with them and they would nonchalantly open it completely up showing me all its tightly arranged 'innards' while at least giving it a good internal dust/dirt clean job for cheap lunch and a beer (& so much dirt/dust/lint there was!)...these are the same folks who build the things of course...fast moving hands with tiny screws flying everywhere, but everything 100% all back in place when finished.
    My Chinese friends also said that nowadays Apples are not as well built as when my Powerbook was built, that nowadays an Apple's life expectancy was considerably lower, so I fear that when I get a new computer that, though it will be more up-to-date and powerful, etc., it most probably won't last near as long as my Powerbook has. They also said that in an older computer the fan was often the first component to go bad, and if a new one couldn't be easily found, as they said was my case, then you're just left with having to get an entirely new computer.  Part of why I dislike electronic computer gadgets generally is that they are obsolete so quickly.
    So, anyway, thanks very much for your information.

  • External hard drive compatible with macbook pro 10.5.8

    external hard drive compatible with macbook pro 10.5.8, i need a hard drive that will work with 10.5.8 to back everything up before upgrading to 10.6. a hard drive that is compatable with 10.5.8 has been impossible to find, a hard drive that works with both opperating systems is what i am looking for, any information that can help is appreciated

    You can buy just about any USB2.0 hard drive and use it with your MacBook Pro.  Many older external drives come pre-partitioned and formatted FAT32 for use on Windows.  Your Mac can use that file system as well, but it has limitations on file sizes.  You can always re-partition your external drive and re-format it as HFS+ (MacOS Extended Journaled) then your old Mac OS version and your new one should both be able to access it just fine.  One thing to keep in mind is that many older OSes don't really handle drives larger than 2TB well, so you would probably want to try to keep your external drive to something smaller than 2TB...

  • My external hard drive works on PC but won't even show up on my mac?

    My external hard drive works on pc but won't even show up on my mac? What can I do?

    If it is in the wrong format it must probably still show up though, if your mac does detect it, go to disk utilities> choose the device from the left hand side > go to the "erase" tab and change format to "Mac OS extended (Journaled) then hit "erase".
    IMPRTANT! : this will erase ALL of the files on your external hard drive
    If this dosent work, make sure your external hard drive's USB port is compatibe with both USB 2.0 and 3.0 and also make sure your mac USB socket isnt damaged either.
    Hope this helped

  • With Time Machine I have an external hard drive formatted with Mac

    With Time Machine I have an external hard drive formatted with Mac. The record contained files windows. How to recover?
    Serious mistake: to connect a Mac to an external drive with data (important!) Windows, the warning appears: "You want to use the disk for Time Machine?" Wrong button, so in 2-3 seconds, the disk is formatted. Now Mac "sees" the disc but empty, Windows does not see it under "My Computer" but in "Disk Management" is reported as "hard core", "healthy", "GPT protective partition" Is there a way to retrieve the files? Sorry for my English Thanks

    I'm having a difficult time following, I understand English isn't your native language. You may have good luck with Google Translate.
