External HDD capacity available used

I have a 1.5 TB Seagate GoFlex Desk Media (External Hard Drive). I have just formatted it to Mac OS Journaled (it use to be NTFS, and before that it was FAT). And for some reason in Disk Utility is states:
Capacity: 1.5 TB (1,500,298,346,496 Bytes)
Available: 1.5 TB (1,499,503,353,856 Bytes)
Used: 795 MB (794,992,640 Bytes)
Why does it say I have used 795 MB? When I just erased it?
Thanks.

Yes, the system must have a place to keep track of where your stuffs goes.
Think of it as the labels on the outside of filing cabinets drawers. They tell you where to find stuff in the cabinets.
Well the system needs the same thing to keep track of where it sticks your stuff on the disk.

External HDD formatting for use in Mac OS X and Windows

I've been gifted with WD (My Passport) 1TB External HDD. On the box it says it requires reformatting for use in Mac OS X.
I used the earlier discussions. I couldn't decipher the steps details as it was mostly by level 4 above.
Can any honourable member advice me on how to reformat my new external HDD for use in Mac OS X and Windows (As in office and during meetings I might haveto use wwindows system)
Also if done with formatting will this be allowing to setup Time Machine back ups.
Please be sure that I want to use time machine exclusively for backup, some earlier discussions mention that TM can also be used for OS booting etc.,
I would be greatful to all who will help me in these regard

Normally the drives are formated as exFAT which could be used by both a Mac and a PC out of the box. Connect the drive to your computer it should be able to read it. If not then the system will ask you if you want o erase the hard drive. Select yes, it will format the drive for use with a Mac only. This is the required format to use it as a Time Machine backup. As stated in our post you would like to use this hard drive on both Windows and Mac, you should reformat the hard drive as exFAT in disk utility.

Time Capsule External HDD Capacity

Hi,
Latest Time Capsule how much capacity of external USB HDD will be support.
Thanks,
Prem

As big as you can get.. 4TB is now readily available.
But I do not recommend using multiple disk raids as they are often not able to work.
You can use multiple disks.. you will need a powered hub anyway.
WARNING.. it is USB2 and it is slow.. about half the speed of the same drive plugged into a computer.
That is just the nature of handling files over networks to USB. It may not be noticeable from wireless.. but from ethernet the internal disk is much faster than USB. So you don't need fast disks.

I am new with iMac and I am trying to copy some file from my external HDD but it does not let me also I can't delete anything from this HDD using the finder. Can somebody help me , please?

No, unfortunately, when you format a drive, it will erase all the contents. So you will need to find a temporary "storage" place to put the stuff using a PC so you have access to it. Then reformat using Disk Utility (Applications > Utilities). If only using with mac, format Mac OS Extended (Journaled) and use GUID Partition scheme under Partitions/Options. After formatting, you can drag the files back.

External HDD or Network Server

I'm posting this here because it does fit into the category, and I really didn't know where else I should put it.
I currently have two LaCie 500GB external HDDs that I use for Time Machine and dumping digital video. I upgraded the HDD in my MacBook Pro to a 500GB HDD, so now I'm looking for something bigger in the external department. I had a friend that wants to buy the old drives from me because they support eSATA, so that will give me a return to put towards a new drive.
I was looking at G-TECH, and I think that's the route I want to go. Perhaps a 1.5 or 2TB drive should suffice for a long while.
Another option would maybe be a server. I currently have an old Gateway running under my desk as a simple web server. The specs are circa 2003, but it gets the job done. I was considering investing in something to act as a file and web server. I know I wouldn't be able to use Time Machine, but I would at least be able to back up the most important files or use something like SuperDuper.
I have an older desktop computer around here somewhere that has better specs than the Gateway: 2GHz AMD Athlon processor, 512MB of RAM and a 80GB HDD. It would be pretty cheap to upgrade the RAM and stick a couple large HDDs in the tower. Perhaps replace and add fans to keep it cooler and much more quiet.
Anyway, I guess I'm just looking for opinions and suggestions. Any comments will be appreciated. Thank you.

TM doesn't back up to network servers, or PCs.
From: http://support.apple.com/kb/HT1733
+Time Machine backs up to either an external disk (such as a USB 2.0 or FireWire-based third-party drive), a secondary internal disk or partition (if your computer supports additional internal drives), a Time Capsule, or an available Mac OS X Server version 10.5 volume.+
Your best bet, by far, is a directly-attached FireWire drive.

External HDD to 2T Time Capsule?

My 2T TC has 824G available, not enuf to back up my big ol' MacPro. I want to add to the TC the 1.5T external HDD I was using for TM before I added drives to the MacPro. I would prefer not to lose the existing backups on the external HDD. Possible? Spring 2010 issue TC. Guidance appreciated.

If you were using Time Machine to back up to that HDD when it was mounted locally, the problem is that Time Machine organizes local backups differently from network backups. See item 18 in this post for more information. About 2/3rds down that page is a procedure number 3, which described a related process. You won't follow the exact same procedure, as those backups already exist on that disk.

I have a new MBAir 2013 13", and I had a MBPro 2010 13". I've installed iPhoto 9.4.3 but now iPhoto says my library (stored on an external HDD) cannot be read until I update the software because it's made with an updated iPhoto... but it IS updated!

As the tile says, I've recently bought a MBAir 2013 13". When I installed and updated iPhoto, I wanted to use my library, stored on an external hdd, which I used until the day before on my old MBPro 2010 13", without any problems. Now iPhoto says that this library cannot be opened by my iPhoto but it has to be opened with an updated iPhoto... but I had iPhoto 9.4.3 on my MBPro and I have iPhoto 9.4.3 on my MBAir! What can I do? Thanks a lot (sorry for my english, I'm Italian)

It's mac os format
BTW I solved my issue! I repaired my library with the last option... and I did not lost anything thanks anyway!

External HDD keeps changing from HFS to NTFS

Greetings,
This is my first post and I am also brand new to apple. I have an issue that I am wondering if anybody has experienced it.
I currently migrated from an old PC (XP SP3) to OSX. I have files on an external HDD that was used on the PC that I now want to use on the mac. (Formatted NTFS)
Now I know that NTFS is not writable in OSX but here is where my issue lies.
I currently have a MB463LL/A model with 2.26 and 4GB. I am currently using a 250GB ext HDD for backup purposes for a photography business (not using Time Machine yet). I recently transferred the files to another external HDD, 1TB, (as to not lose the photos) and used disk utility to erase the 250GB disk and formatted it using the HFS Extended format. (might not be the correct one so correct me if I am using the wrong format please.)
After transferring the files back to the HDD, the HFS reverted back to NTFS, and I am unable to write to the drive again.
Any suggestions as to what is happening?

After transferring the files back to the HDD, the HFS reverted back to NTFS, and I am unable to write to the drive again.
Are you 100% positive it is NTFS again (I am seriously doubting it could do that))? Does it say so in Disk Utility, or are you just interpreting it is because you have write problems?

Daisy Chaining External HDDs

Okay, I know this has been asked a couple of times around the Discussion Boards, but I want to clarify and expand upon it.
Right now I have one 500GB LaCie d2 External HDD that I use only for Time Machine. This works out great, however, as I download more content from the iTunes store, buy more music, etc., it's evident that I'm going to need more space eventually.
My plan is to buy two or three more 500GB HDDs. Each will be used for a different purpose: one for iMovie, one for iTunes and video, and maybe one more just for extra storage if I need it. I don't really need to go any larger, and I don't want to ever put too much on a HDD anyway incase it ever bites the bullet.
My question relates to daisy chaining all of the drives. I use Firewire 800, and I just want to make sure that I should have any problems if the HDDs run daisy chained together. Also, do you think I would have any problems keeping the drives on all of the time if they were rack mounted?

Theoretically you should be fine daisy chaining the drives as long as they are individually powered. I think those people having problems may be related to the particular drive cases being used. One way you could cut down on the number of external cases is to get a dual drive enclosure. This is the one that I am using:
http://eshop.macsales.com/item/Other%20World%20Computing/MEFW924AL2K/
Just buy two hard drives and install them into the case. Set the jumper to JBOD and both drives will mount over a single FW800 connection.

HELP! Library on my External HDD shows up and doesn't show up on another

So I've been working on this project last night (from my external hdd), and completed it halfway before calling it a night. I just close the laptop and let it sleep. Now, I'm trying to open my project I don't see my external's library, which is normal sometimes, so I click my "Open library" and select my external hard drive's library. I get the usual loading bar at the top of the screen, but when it finishes loading, nothing appears! So I click "Open library" and select my external library again, then I get this message:
I have the latest FCPX 10.1.1 and my project library has already been updated. The part that I don't understand is that, I also have another external hdd that I use, but it opens the library on that external hard drive just fine. Is there some sort of preference file I should delete to fix this?? Your help is appreciated!!

@ Tom - I changed everything to Read/write, but still nothing. So I made a new user and it appeared! But my project folder was empty and the event, for which the project I was working on (titled "Jordan & Kaley Wedding"), was empty as well. Like this:
It shows that I have no projects in my project folder, but it opened with one of my projects that I had worked on previously on my external, so I don't understand how its working.

Replacing old TC with new larger capacity TC and using old TC as an external HDD

I currently have a 500GB 1st gen TC. I am running out of space for back ups and running out of room on my iMAC HDD. I would like to purchase a nw 2TB TC to back up both my iMAC, macbook, and expected Macair when the new ones are released.
Questions:
1. Can I use the old TC as an external HDD only? I would like to place my iTunes Library and photos on it so it is visilble accross the network via wi-fi.
3. If I move my libraries is there a method to make them available to me when I travel via the internet? Or is this the upcoming cloud sharing I've heard so much about?
2. My understanding from vaious discussions is that I can not connect the old TC (via the TC USB port) directly to the the new TC and have the old one continuously backed up to the new one (iMAC---new TC usb---old TC). In other words, if I were to move my itunes and photo media to the 500GB old TC then they would not be backed up. However, what if I conencted the old TC directly to the iMAC?
old TC----iMAC---new TC
Would it back-up to the new TC now? Can I connect it to the iMAC ethernet port or would i have to use the USB connection?
3. Can I daisy chain them together in a way that the new TC will backup both the iMAC and the old TC?
iMAC---old TC----new TC

You can connect a USB drive to the TC, and back up some or all of your Macs to it instead of the TC's internal HD. See #Q2 in Using Time Machine with a Time Capsule.
And you can put other data there, too, such as your iTunes library, but for best results you'll want to partition the disk. Otherwise, Time Machine will, eventually, use up all the empty space.
Also note that Time Machine cannot back up from any network drive, so you'll need to find an alternative way to back up that "other" data. The Chronosync app might be viable.

VMware Fusion - Journaled External HDD using MacDrive or NTFS?

I plan to use VMware Fusion running XP Pro via a Bootcamp partition. Along with this I would like a dedicated external HDD for my windows work files (Premiere Pro etc). The trouble is, I'm not sure what way to go with the formatting of the external HDD.
Would I be better to run MacDrive on the Windows system and work off a Journaled format, or NTFS (with something like Paragon on the OS X side)?
I don't want to use FAT32 as I will be working with large video files (<4GB) on the windows side.
Has anyone had any experience with this?

I'm not really answering your question (sorry), but you can create a virtual hard drive from within VMware's interface. The file for the virtual hard drive can reside anywhere, including your external drive. It will start out small and grow up to the max size you specify when you create it. On the Windows side, it looks like a regular hard drive. In my case, my second drive mounts as the "E:" drive.
I find this useful, because the virtual drive does not take up my whole external drive. And the external drive can be formatted for Mac (HFS+) while Windows XP thinks the second drive is formatted for NTFS. In my case, the file for the virtual drive resides on an external drive that I uses for other Mac things.
Now, if you want to share data from both the Mac and Windows sides, instead of using a virtual hard drive (or a real hard drive), you can use WMware's Shared Folders feature to map a share point on the Mac side as a network drive on the Windows side. In my case, I have a folder in my Mac OS X user Documents folder mapped to drive Z: in Windows. Since it's not really going over a network, it is fast.
So if I use this drive in Windows, the files are immediately available in Mac OS X. If you access that folder in Mac OS X, the changes are immediately available in Windows. I can probably go the other way and connect from the Mac side to a share point on the Windows side, but I haven't figured that out yet.

External HDD mirroring using USB Interface

Has anyone out there explored the possibility of mirroring two external HDDs (identical ones) through the USB interface ? If so, I would like to know how it can be achieved.
When I say mirroring, I mean that a single write operation actually duplicates the information on two separate external disks simultaneously. Much like the professional RAID mirroring on more expensive solutions. I am looking at a very inexpensive way of having redundancy built in for safeguarding my data. Perhaps some app out there can do this for me ? Or perhaps this may be a good idea for a brand new App ? Compromise on speed may be an issue, but it would be great value for money.

That is actually a classic backup solution using time machine, where both boot drive as well as EHD is being backed up incrementally in a format which is native to OS Mavericks. Such a backup can only be used to "Restore" the files back onto the source machine. Excellent for normal backup operations.
However, what I have in mind is two sets of EHDs (external HDD) formatted to FAT or maybe the NTFS, where the files are kept in a standard format and can be read on ANY machine whether OS X or Windows.
On a proper mirrored system, both HDDs appear to be one only, and the filesystem also appear to be one. So when we handle a file from the mirrored system, the cloning on the two HDD is done transparently without the user getting to know of it. Failure of one HDD will not result in loss of data since that would be available on the other HDD, and when the faulty HDD is replaced, the data gets replicated again from the good HDD. Such a mirrored system is very expensive and not affordable by ordinary mortals like most of us.
So, to get around the expense part of the whole thing, now that we have fast USB3 interfaces, we can possible use 2 x cheap EHDs hooked onto two separate USB 3 ports, and use them as a mirrored set. It is understandable that since the computer cannot access two USB ports simultaneously, there will be some trade-off to the speed of handling the two EHDs, but, that is acceptable. At least we have two identical sets of data available, which can be used in an emergency on any other system. Should one EHD crash, we can always extract all data from the second one.
I am not sure if such an arrangement is possible using the existing functionality of the OS X, and so someone may need to whip up an app or a script for doing this. Alternately, some really clever geek could come up with some remarkable solution/work-around. Looking forward for some bright spark from somewhere.

Limiting Space used on external HDD for Time Machine

I'm really clueless on how this works and I would appreciate your thoughts on this. I recently bought an external HDD and I want to limit the allocated space for TM to only half of the capacity. I recently formatted the external HDD to FAT32 in order for me to use it with my other systems.
Is it possible to make this work? I saw an article wherein you can create a disk image in the external HDD, will that work?
Below are some specs of my external HDD:
Objective: Use Time Machine on my 1TB External HDD while limiting the space to only 400MB for back-up.
External HDD Settings: Iomega External HDD formatted as FAT32 and Master Boot Record

Hello,
Here is the best solution I can think of without using any extra software to alter your Time Machine settings.
You could use Disk Utility to divide the 1 TB external HDD into two partitions (400 GB + 600 GB).
(/Applications/Utilities/Disk Utility.app)
Warning: Using Disk Utility to divide the drive into two partitions will erase everything on them.
Once that's done, when you reconnect your hard drive to your computer, and open Time Machine in System Settings, you could assign Time Machine to the 400 GB partition.
Here is the catch though, Time Machine cannot backup to FAT32, so you would have to format at least the 400 GB partition as "Mac OS Extended Journaled" with Disk Utility. If you want to use that drive with other non-Mac systems, best solution would be to share it over the network.
That is the best I can think of for your problem. Hope that helps.
