What size is my harddrive? on

I'm a bit confused here. If I do a "df -h" it shows /dev/disk0s2 as being 233GB capacity. It also shows a /dev/disk2s2 as being 465GB. I only have one HDD in this macbook obviously. Is disk2 a compression-enabled version perhaps? Both show the same amount of free disk space.
Thanks.

System profiler shows a 250GB HDD as I suspected.
Here's the full output from df -h:
$ df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s2 233Gi 205Gi 27Gi 89% /
devfs 109Ki 109Ki 0Bi 100% /dev
map -hosts 0Bi 0Bi 0Bi 100% /net
map auto_home 0Bi 0Bi 0Bi 100% /home
/dev/disk2s2 465Gi 438Gi 27Gi 95% /Users/bb
Here's what "mount" shows:
$ mount
/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)
/dev/disk2s2 on /Users/bb (hfs, local, nodev, nosuid, journaled, nobrowse)
Here's what diskutil shows:
$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUIDpartitionscheme *250.1 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 249.7 GB disk0s2
/dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: Applepartitionscheme *499.4 GB disk2
1: Applepartitionmap 32.3 KB disk2s1
2: Apple_HFS bb 499.4 GB disk2s2
Assuming it's disk compression, is this enabled normally? I suppose I might have selected it when I first started using the macbook and have forgotten, though I usually avoid compression. I did turn on encryption for my home folder.
Thanks for any more ideas.

What "size" is my harddrive?

I have an old TI powerbook that kind of died last year (logic board issues). Bought a new iBook to use since then. BUT would like to take out the old TI harddrive and install it into an external enclosure to use but not sure what size enclosure I'd need. I assume it's 2.5"? One enclosure I'm looking at said "Suitable for 2.5" notebook hard drives that are 9.5mm in height" Would that be what I'd want?
Thanks for any help someone may have. Haven't been able to find this info on the Apple site.....

Hi Michael,
That is the standard laptop HD size and would most likely be what you need (although some years ago they did make a slightly taller one, I think it was 12mm in height, though I don't know if any TiBook came with one).
One comment on the enclosure: if there's any possibility you would ever want to clone/install an OS onto the external HD, you'll need a FireWire enclosure to boot a Mac.

What size is my music library

what size is my music library

I do not know the size...but iIneed to ask a question and there is NO place on this site to ask...So I will ask here.
I downloaded some songs from a legitimate site and when it cam to where i want those songs to go, I clicked on i-tunes. Well, apparently this caused my regular Library to vanish and it was replaced with a new library called 'i-tunes 1'. I do have an external harddrive and back up cd's..but i thought asking Apple Support for help before i do all that. I have yet to hear from them and they really are not reliable..all they do is direct yoiu to the helkp site...like i can do that on my own.
Any suggestions? I even l;ooked on my hard drive and when I click on -tunes it automatically opens to this new library.
HELP.....Thanks!!

What do you mean a moderator

For the life of me, I can't find out what size a photo is in terms of inches or how to change the size of the photo[s] so I can print them. I think I read somewhere to click edit, then click adjust. Nothing there about sizing.

For the life of me, I can't find out what size a photo is in terms of inches or how to change the size of the photo[s] so I can print them. I think I read somewhere to click edit, then click adjust. I don't see anything about re-sizing when I click the adjust tab: only saturation and tint levels. Thank you.

With respect to digital images, there really is no size in inches. The size is given as number of pixels horizontally and vertically. In iPhoto '09 you click the little "i" inthe lower right side of the window and it will display information related to the selected photo, including the pixel dimensions. I do not have iPhoto '11 installed so I don't know if it is the same there.
In some applications, such as preview, it has something additional called Dots per Inch (DPI) which you would think would allow you to convert the pixel dimensions to inches. It is not a real thing, though. The DPI is determined by how large or small you have chosen to print your photo and the capabilities of your printer.
There is also something called Aspect Ratio, which is usually expressed in inches x inches such as 6x9 but that doesn't mean the size on the screen or when printed is 6x9. It is the ratio of the pixel dimensions. When cropping your photos, you will have several standard aspect ratios to choose from plus any custom ones you create.
In iPhoto '09, after you choose Print, in the Print Setting window are the settings for the size you want the photo printed. You want to shoose a setting with the same aspect ratio of your photo. Otherwise, iPhoto will resize and/or crop your photo to fit the size you have chosen.

What size external hard drive should I purchase

What size external hard drive should I purchase? I'm not tech savvy, so please speak slowly. I'm looking at OWC Mini Stack Classic to match my older Mac Mini. Do I need 500 GB, 1 TB or more? Plus, I have to add memory to upgrade to Snow Leopard. How much memory do I need and should I have an expert install it ?
Mac OSX version 10.5.8
Mac mini 3.1
Processor 2 GHz Intel Core 2 Duo
Memory 2GB 1067 MHz DDR3
1 Processor
2 Cores
L2 Cache 3MB
Memory 2GB
BUS Speed 1.07 GHz
Boot ROM Version MM3.1.0081.B06
SMC version 1.35f0
Hard Drive
Format MAC OS Extended
Capacity 297.77 GB
Available 238.69 GB
Used 59.08 GB on disk

Good points raised by all.
In my mini configs - both older and newer flatter model - I have kept their ministack external drive on top of the mini; with 3 or 4 little rubber feet added to the mini's base to give it a bit more elevation from the surface they are sitting on and a bit better chance to breathe. I'm not impressed by the very small air intakes on the bottom and the hot air that often comes out the back or how warm the case feels. Especially in the heat of summer.
I do turn the ministacks on/off as needed (primarily for backups once a week) as they're not entirely quiet and sometimes seem to have a low hum vibration. Nothing crazy. I just like it as dead quiet as possible sometimes. Plus the fan does not turn off even if the mini and ministack drive have shut down. The newer wide & slim model does seem a bit quieter than the older model.
Check through system profiler to see if your system has 2x1GB or 1x2GB. Most likely it is 2x1GB and you'd need to remove both to double your ram. On the off chance it has a free slot; a single 2GB stick would get you to 4GB. Check on the cost difference between the 2x2GB kit and a 2x4GB kit. I have an older core duo mini that functions fine with 2x2GB of RAM and 10.6.8. But, if you plan to continue to use the mini for several more years as a primary machine including upgrading the OS to Yosemite; it might not be a bad idea to just max it to 2x4 8GB. Yosemite really likes RAM to maximize performance.
Along the lines of keeping the same mini and doing upgrades. The biggest speed improvements are made by replacing the original internal hard drive with a flash drive. Of course this is a more technical upgrade, you really need to take the mini apart more and you have to weigh the cost of the upgrades and possibly paying somebody to do them; vs the cost of a newer system which would have a significantly faster processor and other improvements.

To install Windows 8 OS on a new iMac using Boot Camp, what size "partition" should I allocate for Windows on a system with 3TB Fusion drive?

I am trying to install Windows on a new iMac w/3TB Fusion drive. The system crashed on my first attempt but appears to have partitioned the drive correctly before crashing??? So, what size partition does Windows 8 need to operate effectively? Is "more" better??? or just over-kill? And, has anyone installed Winodow 8 on an iMac...and how did it work? Would apps like "Parallel Desktop" or "VM Ware Fusion" be a good idea and troubleless?
I will try again but not too confident that it may get worse before it gets better.
Regards....?
P.S. I configured this iMac with the i7 processor 3.5GHz with Turbo Boost to 3,9GHz. When I select "About this Mac" it diplays my i7 processor as a 3.4GHz instead. Do you think they ran out of the i7 3.5GHz and shoved a i5 3.4Ghz in the iMac to meet deliver schedule??? I there a way to check the real-time speed of my processor??.

It depends on your uses. See > https://discussions.apple.com/docs/DOC-3321 Windows 8 works properly in Boot Camp, always that your iMac is compatible > http://support.apple.com/kb/HT5634?viewlocale=en_US&locale=en_US You can only use the 64-bit Windows 8 edition.
Respecting to your processor, you may want to contact with Apple, as they may have sent you the iMac with a wrong processor

What size hard drive will fit into a 2010 Mac mini?

Hello all,
I am planning to buy a new Mac mini. However I intend to upgrade the hard drive, i.e. buy a 320GB Mac Mini then remove the hard drive and replace it with a better one.
I have my eyes on two Western Digital hard drives:
+ WD Scorpio Black 750 GB SATA Hard Drive (WD7500BPKT)
specs: http://www.wdc.com/global/products/specs/?driveID=905&language=1
+ WD Scorpio Blue 1 TB SATA Hard Drive (WD10TPVT)
specs: http://www.wdc.com/global/products/specs/?driveID=685&language=1
Here's the problem. I figured that being both SATA 2.5" drives, they would have the same dimensions. It's not the case:
+ my preferred choice, the Scorpio Black (with faster 7200rpm) has a height of 9.5mm
+ the Scorpio blue (1TB but 5200rpm, slower than the default drive) has a height of 12.5mm
So I wonder, which of them would fit in the mini? Both of them? Afer hours looking for it, I couldn't find the exact specs and dimensions of the default drive in the Mac mini.
Questions this arises: if the Scorpio Blue fits in, then will the Black be loose because it's thinner?
I just went to my local Apple retail store, the flagship Opera store in Paris. I asked two Geniuses there and neither of them was able to answer my question, including the so-called hardware expert (duh!). They just told me "good question", and advised me to be careful with dimensions indeed because there is so little room in the mini...
Has any of you guys any clue on the subject?
+ any idea of the size/specs of the default drive?
+ any idea of what size drive would fit? Does the new disk have to be the exact same size or not?
FYI I checked the specs of the mini they had on display, and the disk reference is TOSHIBA MK3255GSXF. It looks like a specific ref number for these Apple drives.
Thanks!

6 MONTHS LATER/UPDATE.
I got the the Seagate Momentus® XT 6Gb/s 750GB Solid State Hybrid Hard Drive. Was able to install it myself in the Mac mini; it works great! (now).
My original 350GB was near full and taking almost 5-minutes to load.
Now my computer boots up in under one minute. Big difference!
Apps also snap open quickly, all functions fast and with 8GB of Ram using my computer is fun again.
Note: Initially I just made a clone of my old HD to the Seagate before taking my old HD out. This did make a bootable volume but funky and eventually the mouse clicks took 4-5 minutes to work!?
So I wiped the Seagate clean, did a new/fresh install of my Mac OS onto it and then used the Apple Migration Assistant app to get all my apps and data over - This worked and no funky stuff developed.
It's the best change to my computer in years. Feels great...and besides the features of the fusion-sytle hybrid drive (SSD & regular) I got 450GB of new, extra space...now I can put my work aside for awhile and try out one of these 12GB games!. Rock on.
INSTALLATION INSTRUCTIONS: patience, patience, patience and instructional video at OWC; yet the insides were different, an extra plastic 'cage' around the HD. Just be careful & alert.

What size external hard drive do i need to backup my macbook pro?

I know I need to backup my computer, especially since I have been experiencing some problems with it and will need to take it into a store to get looked at, but I do not know what size external hard drive I need to back my computer on.

Drives are so low in cost today, go for something that will meet your needs for a while...if you are going to use Time Machine, get a drive large enough that you can have a partition double the size of the internal drive for TM backups, and a partition you can use for more storage and work space.
A decent drive like the Mercury Elite Pro 2 TB drive OWC sells goes for less than $200 (US) now. Has a fast interface and is easy to setup.

What size external hard drive do i need for Time Machine

What size external hard drive should I get to be my Time Machine backup? My iMac is 1TB. (also, I have MBP that is 250gb and will need one for it as well)
Thank you.

It is better to buy an external drive that has 3 times the storage capacity
as of the computer's internal HD.
Best.

What size SSD? Swapping Optical Drive for gen. storage.

I'm planning on buying a smaller SSD and was looking for suggestions on the best size to buy. I have a 13" Late 2011 Macbook Pro, i5. 8gb RAM. 500gb HDD.
What I'm doing is replacing my 500gb HDD and moving that to my optical bay just for general storage. I'm going to set up my new SSD as the boot drive. I want to boost my performance for as little money as possible. I know that I can put 16gb RAM in and get significant improvement, but really want to get rid of the HDD as the boot drive. I'm leaning toward getting either the 44gb or 60gb Mercury Electra 6G SSD.
Any suggestions on what size would be best for what I want or any other suggestions are welcome.

I suggest that you get at least a 240 GB SSD. SATA3, of course!
Larger SSDs are generally much faster, and the price is now dropping (to the point that I have just purchased an 1Tb Crucial M500 SSD for less than 400 €). The price difference between a 64 GB SSD and a 240 GB SSD is now minimal, and you will enjoy more space!
Two years ago, as soon as I purchased my late-2011 MBP, I immediately did the same, moving the original 750Gb HD to the optical bay, and installing a 240Gb Vertex-2 SSD in the main bay as system disk.
The space was just enough, as I have Bootcamp and Windows 7, too, so I divided it half-and-half, and a 128Gb storage is just barely enough for either OSX and Wndows-7 64 bits Pro...
You could survive with a 128 GB SSD if you do not need Bootcamp. Indeed, I always recommend to install Bootcamp and Windows 7 to all Mac owners, so you get the best of the two worlds. I love OSX, but for certain tasks Windows is still vastly superior (using Autocad, for example)...
Curiously, instead, I prefer OSX for Office...

What size should my movies be to not get cut off?

I am making a tutorial DVD. I used Snapz Pro to record a bunch of screen capture movies and then edited them together in FCP and exported them as 1024x768 animation movies and they look great. Now I want to burn them to DVD. When I take them as they are and put them on a DVD the top and bottom of the screen get cut off. Can I just resize the movies in QT pro to a different size so they won't cut off? If so what size? Is there a better way?

Scott,
A mix of this QuickTime Pro: How to Make Picture-in-Picture at http://docs.info.apple.com/article.html?artnum=42633 and the following procedure I put together a couple of years ago to use the small movies produced by still digital cameras in iMovie/iDVD:
1. Create a 640 x 480 black mask with a slightly lighter black 320 x 240 center in Photoshop. Save it as a JPG file.
2. Open your DiMage X movie in QuickTime Pro. Open the saved mask in another QuickTime Pro player (at 15 fps).
3. Select the mask clip and edit->select all and then edit->copy
4. Select the DiMage X clip and then edit -> add scaled the mask
5. Next, select movie -> get movie properties
6. Select video 2 on the left box and layers on the right box. Set the layers to 1 (that moves the mask to the back).
7. Select video one on the left box and size on the right box. Click on adjust. Red hack marks appear around the video. Click on the picture (not the mark) and center the video on the lightened 320 x 240 box.
8. The video may not completely cover the lighter box, but the hack marks should line up. When you view the movie, if you used a "slightly lighter" black for the center area, you won't a notice a lighter area when played in iDVD.
9. Export it as a DV stream. Bring it into iDVD.
will give you an idea on how to proceed. Obviously, you will need to come up with your own mask and cut-out size - 640x480 ISN'T what YOU want.

The issue is that he doesn't know if he will use the memory or not. To be sure, he should go BIG! The differences in cost between the small and large versions are not that much anyway.

How do you determine what size tablet to get (storage wise)?

I looking to get a table (either the IPad or the Asus Transformer Primer. I'm thinking of using it mostly for travel and would like to use it for internet connections, email and downloading & watching movies & music. How can I figure out how much storage (16gb, 32gb, or 64gb) I'm going to need?
Thanks!

I determined what size of tablet I got (storage wise) based on two things: 1) Price and 2) Whether or not I could easily expand the storage.
For starters, you are going to get the most bang for your buck from the Prime. The 32GB Prime costs the same as a 16GB iPad. So right there you have twice the storage for the same price.
If you happen to fill up the 32GB of internal storage (which is not that hard since you pan on loading the thing up with movies and music) you can simply get a 32GB micro sd card for 40$ and double your space (this is not even an option with the iPad). Also, you could add even more space via the SD card slot or the USB port on the keyboard dock.
With the iPad, once you fill the thing up, you are done. From that point on you have to manually move music and movies off the device in order to add new stuff. I used to have to do this with my old iPod touch and it was quite a tedious and annoying thing to have to do. Of course I only had 8GB to work with back then.

What size for a DVD on Plasma

I am making a little animation in Motion which I am going to burn to DVD... What size would be the best? It's a 42" Plasma Screen... So is it 1024 x 576? or 720 x 576? I'm on PAL also...

If you are making an animation to be played from a DVD player, then the only format you will render to will be 720x576 anamorphic (squashed horizontally). Create your original project in 1024x576 - 16x9 and render to 720x576 anamorphic. The screen will transform the image back to Widescreen 16x9.
If you could find an HD player or play from a powerful enough laptop you could have a much nicer image quality as you could play a native HD screen height. (1280x720, or 1980x1080)
