Reformatting an external drive for sharing over airport

I have an external hard drive that I would like to share across my network plugged into an airport extreme router. I will be using both MAC and Windows computers. Do I have to reformat the drive before using it and if so do I use Mac or Windows for reformatting.
Thanks

You can use either Mac OS Exended (Journaled).....recommended....or FAT16 or FAT 32 to format the hard drive prior to connecting it to the AirPort Extreme.
See this Apple support document for details:
http://support.apple.com/kb/HT2426
Keep in mind that the USB port on the AirPort Extreme is under powered, so it may be necessary to use a powered USB hub with the hard drive.....even if he hard drive has its own power supply.

How do I reformat my external drive for Time Machine?

I think I might have messed up My Passport (external hard drive) when I disconnected my iMac to take it to the Apple Store to have the screen repaired (was replaced). I turned Time Machine off before I disconnected the external hard drive but didn't eject it. I reconnected everything Monday morning and it was backing up fine until this afternoon but suddenly stopped and gave me warning messages about it not being able to back up. The message directed me to Repair Disk which I tried but that didn't work. and I was "told" to reformat the drive. But when I reconnect it to my mac, the mac doesn't recognize that its there. I don't know if its worth trying to fix, or if I should just get a new one. (I have an on line back up service so all my data is safe and backed up elsewhere). I've only had the drive for maybe 6 mts, or a little longer and I know it was far from full. I have Time Machine turned off now and the drive disconnected . Is it worth repairing. If there is something wrong with it a new one might make more sense. I hope I have explained this okay. Thanks for any suggestions. It is a Western Digital external drive.

WD drives are not all that reliable according to some reports going around.
And BUS powered drives are not good choices for backups if it's drawing too much current, Apple can cut if off in a update, use self powered drives instead.
You can use the drive, but as a transport drive, not as a vital backup.
TM drive isn't quite as good as a backup as it could be, and online storage is slow to upload and can be compromised or lost (it's happened before) so you should diversify more with clones and storage drives in addition to TM drives.

HT201250 Should I reformat a external drive for time machine to work?

I am setting up a new time machine for a new MacBook Pro and am going to use a drive that I previously used for backing up a windows computer. Will I need to reformat to drive. I assume I will have to.

Yes.. Time Machine requires Mac OS Extended (journaled)

I can not store all my Music on my internal Macbook pro hard drive so I am storing it on a large external drive connected to my airport extrem. How do I get Itunes to search for the music here with out trying to copy it to my laptops hard drive??

I can not store all my Music on my internal Macbook pro hard drive so I am storing it on a large external drive connected to my airport extreme (2 TB drive plugged into the USB port). I see the drive on my laptop and I can add and delete files no problem. How do I get Itunes to search for the music here with out trying to copy it to my laptop's hard drive? I don't have enough space to do that.

How did you move the music to the external drive? What exactly is on the drive? The entire iTunes folder or only music? If it is the entire iTunes folder you can do the option+start suggestion earlier. If you copied only music and did so by dragging it there then you need to delete it again and consolidate/organize it there instead so iTunes tracks the move. iTunes 12 for Mac: Change where your iTunes files are stored - http://support.apple.com/kb/PH19507

Using an external drive for my iTunes Library

One post, many questions.
Sometimes I inadvertently open iTunes with my external drive turned off. It holds my library contents.
iTunes however, with no warning or message, just reverts the library location to my internal drive and throws whatever it wants to download there (usually a few podcasts).
My bad, I know. I leave the drive turned off because I often don't need it for up to a week at a time. My iPod charges in the car as I drive around.
I end up with my library split, all but a tiny bit of content over on the external drive hooked to my airport extreme, and that drive removed as the library location in iTunes.
So I change the location, let iTunes reorganize my library, and go on my merry way. I'd like to make it not happen. No, leaving the drive on is not an option. The answer to the question "Do all your little light up boxes REALLY need to be on all the time?" is no. It's easier to turn some off, believe me.
I moved the contents of "user"/music/iTunes/iTunes Music to the external drive. Downloads, Podcasts, and TV Shows folders live in there amongst the content. It works great unless I drop my iPod in the dock or otherwise start iTunes with that drive switched off.
Is it safe to go into the original location and delete enough of the file structure to make iTunes at least say "hey! where's the library" rather than changing my set preferences and filing things where I don't want them?
If I delete user/ Music/iTunes/*iTunes Music* from my internal drive will iTunes a. work? b. not see it, so just make a new iTunes Music folder and keep doing what it has been? or c. ask for a library location? (prompting me to turn the drive on)
Should I recreate that naming structure to/on the external drive? Right now the path to the content is shared/airport extreme/OWC Media Storage, with the content then on the dedicated drive. When I send iTunes down this path what shows up as the library location is just OWC Media Storage: . The default iTunes loves so much does show the whole path Travelstar 200GB/user/Music/iTunes/iTunes Music. Is part of the problem my just throwing the content on a drive I gave a non iTunes specific name?

I noticed this is getting views so, I'm posting answers to myself if case it's helping someone else.
I turned the external drive off and started iTunes on purpose to see what it's reaction would be.
It does redirect itself to the original location, remake the iTunes Music folder on my internal drive, and start to download Podcasts.
Is it possible to stop this? Can the path to the iTunes Music folder be locked? I'd actually rather iTunes crashed than reset itself this way.

Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partition?

Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partitioned Time Capsule? I understand that the Time Machine (software) cannot backup a networked drive (the external) and that Time Capsule (the router/wireless hard drive) does not have its own backup software... so it won't backup the connected drive. What I would like is an alternate solution for having an automated backup of a networked drive. A 2TB Time Capsule has more than enough space for Time Machine backups of my family of Macbooks, so I had hoped to mirror a 500GB external drive (with shared media files) to a portion of the Time Capsule internal hard drive. I assume this would require a partition of the Time Capsule drive. If not, would the sparse file from the various computers being backed up need to be copied to the external drive as part of the RAID1 setup? This seems like overkill for the Time Machine backup, but it would cover the media files.

The complexity with this idea is the software has to run from a Mac computer on your network.. so you need a Mac turned on, probably most of the day.
It isn't possible to partition the TC although you can create a image area.
The software would have to copy the material, that means all files to be copied, go from USB drive, back to the Mac, then back to the TC, and written to the drive. In other words you have just added Network congestion, although a proper incremental backup type software will not actually use a lot of capacity.
Finally it will be slow.. network drives are slower than internal drives. Well USB connected drive is much slower than the same drive connected directly to the computer.. and if the drive is connected directly to a computer it can be shared with the network.

Using an External Drive for Time Machine and Other Things

I have a 2TB external drive which I use for Time Machine Backups on my 2 macs. The macs have HDs of 500GB and 160GB so the external drive has ample space for backups.
Is it okay to use the external drive for other things that I don't care if they aren't backed up (like digital copies of DVDs)? i.e. Will Time Machine cause any issues if a drive is used for more than just Time Machine backups?

Maybe. See #1 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

It's best to put such things in their own partition. See #3 in the FAQ.
You may also want to make separate partitions for each Mac's backups, if you're backing-up either one directly (ie, not over your network). See #4 in the FAQ.

Formatted External drive for Mac OS extended

Hi,
I actually change from windows to Mac (no comparison...!!) but trying to transfer my photos (Pictures in finder) to an external hard disk i can`t drag and drop and i do not know why....i read in one forume that i have to formatted the external drive for Mac OS extended. First question: how could i do that? if my hard disk was originally formatted for windows, do i lose the info when i formatted?
Thanks!!

You will lose the files on the HD when you reformat it. So copy what you want off the drive to a folder on your Mac temporarily.
select the HD on the Desktop and launch Disk Utility.
select the HD in the left hand page of DU.
click on the Partiton button
select 1 Partition
select OS X Extended (journaled) in the drop down Format menu.
click on the Apply button
drag the folder of files onto the EHD to copy back and then delete from your Mac's drive after verifying that they all copied back successfully.

HT3275 I am using an external drive for backup. I am now getting a message that the drive needs a disk repair, but when I run disk repair it just seems to freeze.

I am using an external drive for back up. Yesterday the backup failed and I received a message that the external drive( a passport drive) needed a 'disk repair", when I ran disk repair nothing happened it seemed to freeze. Suggestions? should i simply erase the external drive and start over-my computer is fine.

Get a different drive for backup.
In the meantime, once you are backed up some drive safe, then you can attempt to repair the backup drive using the repair the directory link.

Going from xp to windows 7 64 bit using an external drive for music storage

Greetings Techies!
I hope you all are well.
I need to move my iTunes from an XP machine to Windows 7 64 bit. On the XP machine I am using an external drive for music storage and the iTunes database is stored on the internal drive. I am looking for advice on how to transfer all of this over to my new Windows 7 64 bit machine. I know iTunes can be picky about everything and I don’t want to take and chances and loose my playlists or music.
Any help would be much appreciated.
Blessings,
paul

You are right about it being picky. I just upgraded from Vista to Windows 7 and was forced to format my drive. I had all the music backed up, but when I imported it, I have 2 or 3 copies of some songs, art work missing, and have lost my playlists. I hope someone responds to your question, because I could use similar help! Best of luck to ya . . .

What is the best way to set up an external drive for video storage

What is the best way to set up an external drive for video storage?

Check the formatting. It need to be formatted as Mac OS Extended (journaled). This is also known as HFS+.
FAT32 and NTFS formatting will not work with iMovie.
If necessary, you can reformat using Disk Utility.
Make one large partition. No need for multiple partitions.
Do moves or copies to the external drive through iMovie as detailed in iMovie Help. If you move Events in the Finder, they may become unlinked from the projects that use them.

How to best partition an external drive for my purposes?

Hello, please help,
I've just bought a Western Digital 'My Passport' 320Gb USB (no firewire) portable external harddrive for backing up my data prior to iMac repair.
I also plan to totally wipe my PPC iMac and reinstall it with Leopard.
I erased the external HD, zeroing out the data from it's previous owner, and reformatted it as Mac OS Extended (not journaled).
Now I realise that it might be even more useful than I'd imagined.
I'd now like to partition it so I can use Carbon Copy Cloner to create a bootable copy of my entire iMac while using the rest of the drive as a separate partition for just backing up data.
Ideally I want to be able to use the drive on both Intel and PPC Macs and even PCs, is this possible? How should I format the drive to achieve this?
I've heard I should format it as Mac OS Extended (Journaled) HFS+, what ever that is
I'm currently running OS 10.4.11 but plan to buy Leopard and install that after the wipe.

For what you want to do, there is a mismatch between your PPC computer and the external drive that you bought.
With a few exceptions, a PPC Mac requires a firewire external drive for booting and will not boot from a USB drive, regardless of which OS is installed and regardless of the partition scheme and volume format on the drive. I also have an iMac G5, and mine will not boot from USB.
If you do exchange your drive for a firewire drive, do not get another Western Digital model to use with your G5 - many external WD firewire drives will not boot a PPC mac. See [this page|http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/stdadp.php?pfaqid=1787]
If you want to keep your present USB drive, you can still partition it with one partition for a backup clone and another for "other stuff". With respect to immediate use for recovering your stuff after a clean Leopard install on the HD, I think that Migration Assistant will still work, though I haven't tried this. As for the future, the problems with a clone not being bootable are 1) You can't test it to see if it works OK, and 2) If you do need to restore from it you'd need to boot from "somewhere else" - I think you could boot from an install disk and use Disk Utility's Restore feature to clone it back.
With regard to PC access, a PPC mac normally requires an Apple Partition Map partition scheme on the drive for booting, and such a scheme does not allow for the FAT32 volume format that is readable by PCs. However in this case since your PPC mac can't boot from it anyway, you could partition the drive as GUID. This would allow the main volume to be formatted as Mac OS Extended (Journaled) for the nonbootable clone, and would allow the extra volume to be formatted as FAT32. If you eventually got an Intel Mac, a clone from it to the main volume would also then be bootable.
But what I would do, if feasible, is exchange the USB drive and get a non-WD firewire drive instead.

Can I use my late 2006 mac mini as an external drive for my late 2012 mac mini?

I have a (late 2006) Mac mini that I would like to use as an external drive for my (late 2012) Mac mini. Is this possible and can anyone suggest what cables would be needed. I am aware that the ports are very different i.e firewire and thunderbolt. Thanks in advance!

- You can boo the old Mac in Targe Disk Mode and connect the two via FireWire (FW) You will need a FW 400 to FW 800 cable or a FW 800 or FW 400 cable and appropriate adopters
How to use and troubleshoot FireWire target disk mode - Apple Support
- Use the old Mac normally and setup Disk Sharing and access the old Mac via the network. The old Mac's disk will show up under Devices on the new Mac. One you set up the old Mac yo do not need mouse or keyboard or monitor. You can also setup Screen sharing and actually use the old Mac from the new Mac.
- Remove the HD from the old Mac and place it in an external USB enclosure of dock and connect it to the new Mac

Which external drive for backups?

My brand new 21.5" iMac is on its way here today, and I've been told to buy an external drive for backups. Which I think is a great idea. However, my head's starting to hurt from all the info I'm reading here on the forum about WHICH one, Firewire cables, etc etc. The Rocstor 500GB has been recommended to me personally, but I've read about Lacie and a few other brands. I'm thinking it'd be best to get a 1T size. But WHICH HARD DRIVE SHOULD I GET? I don't wanna spend a lot of bucks!!!
Plus I have a Firewire cable but how do I know if it's a 2 or a 4? I bought it when I migrated data from my Silver edition iMac to my G4 iMac back in 2004 or 2005.
Thanks!

Congratulations Sheryl on the new iMac.
I recently replaced a G-4 tower with an iMac. The G-4 had a port for Firewire 400. The iMac came equipped with one Firewire 800 port a firewire cable and 4USB ports. I suspect that also applies to your new machine. In order to transfer files from one machine to the other using Firewire 400/800 I had to buy an adapter from the Apple store. Your help menu will explain how to set up the iMac as a target for the transfer.
As to backup: I use Super Duper and over 8 years had backed up religiously to a Lacie external HD. About the time I needed to use it as a file transfer source to the iMac it quit.
After much study and considering how Time Machine can eat up space I settled on the external hard drives described below - all were partitioned. The Drobo uses firewire 800 and 4 multiple internal hard drives. It is the place where time machine is backed up. The setup was about $600.
The two lacie hard drives are USB 2.0 driven.
I have learned the hard way that it pays to backup the backups.
If I could only have one external hard drive and with all things considered I would opt for the 1TB Lacie Stark (about $125) that is USB driven.
Sure hope this helps a bit. To help further we need to know more specifics about your need.

Formatting external drive for storage/backup/video files

Hi,
I just purchased a 500mb My Book Pro external drive for use with my imac duo which runs Windows XP via bootcamp. This computer is shared by three family with very different skills and needs. My dilemma. I want to format the drive so that the imac can be backed up easily three users. It is formated Fat32 and is supplied with Restrospect Express 7.5 backup software. It would be nice to backup the modestly used windows sector, but that's a secondary consideration. My problem is that one user has a lot of larger than 4 gb video files which are too large the Fat 32 format. My notion is to segment the backup drive so that I leave 300 mb in fat 32 to facilitate backup with supplied software, and segment a second 200 gb drive using mac os extended so that the user can manually move her video files for storage/backup on the backup drive. Is there a simpler solution? For example, if I formatted the entire 500gb as mac os extended, could I still run the retrospect backup software? If not, is there a reasonably priced alternative software? And finally, with either Fat32 or Mac OS extended, can I move files from the Windows platform? Would I be better off just biting the bullet and telling my daughter to make her own arrangements to compress and backup her video files or get her own hard drive, thus leaving the backup drive to the simple factory supplied software solution?

Hello,
You're indeed in a pickle. If you use Bootcamp and want the HD accessible via the Mac and WinXP, then you don't want to format it as Mac HFS because WInXP wouldn't be able to access it. If you go FAT32 then both WInXP and Mac OS can access it, but you face the dilemma of the 4GB threshold.
If you format as NTFS, then you eliminate the 4GB threshold but then Mac OS cannot access it.
I have a similar dilemma, which is why i use Parallels more than Bootcamp. I have 2 external FW HD's (160GB/250GB), both formatted to Mac HFS. The 160GB i have partitioned as 50GB and 100GB. I have a bootable backup of Mac OS residing on the 100GB partition (yay to SuperDuper!) and some other stuff on the remaining 50GB. The 250GB is exclusive for movies (cough..cough..bittorrent) and for streaming via Orb 2.0 to my Treo. I have WinXP running in Parallels, and Vista Ultimate via Bootcamp. In Parallels, i can access my external HD's via Parallel's Shared Folders but in Vista (Bootcamp) since the HD's are in a non-Windows recognised formatting, they're not accessible (which is a bummer, as i'm loving Win media center).
What you can do is partition the HD the way you're thinking and format (one part Mac HFS and the other NTFS), but my best recommendation is that with the falling prices of HD's nowadays, why not just get a seperate HD do what you want with it. I spied a WD MyBook 500GB USB HD at CompUSA for $129.99 (no mail-in rebate nonsense) and similar good prices at Bestbuy and Newegg.com.
