Using FAT 32 formatted external HD with iMAC

just bought an iMac. For my PC, I have a 150GB external harddrive that is formatted for FAT32 and connected via Firewire. Can I plug in the HD into the iMAC and read/write my files? I've read something that says I can't write to the drive, or the files need to be smaller than 4GB. I have MP3 files bigger than this. If I need to, I can read the FAT32 disk, and copy to iMAC, then re-format into MAC format (what ever that is), and write the data back. Can I do this, or am I on the wrong track? Help an ex PC guy out?

Yes you can connect and use this drive just fine. It's NTFS that Macs can't write to. FAT32 does have a 4GB file limit but this applies to PCs as much as Macs. I doubt you have 4GB mp3 files, they would be days long!
Mac file system format is called HFS+ but within Mac OS it's called Mac OS Extended. You can leave it as FAT32 if you wish to use it between the two machines or format to HFS+ with Disk Utility for Mac-only use.

Any one use an Apple MA034 external modem with PowerbookG4 running Tiger?

any one use an Apple MA034 external modem with PowerbookG4 running Tiger?

Not too common with G4 PowerBooks as they have an internal modem. I can't find Apple's sepcs but a third-party ad shows it minimally needs 10.4.3 or higher and a G-series processor. That should work.
However, the Apple version is expensive used. I googled Apple MA034 external modem and found an Amazon page that showed other compatible modems that were much cheaper.

Can I use Time Capsule as external drive with a Time Capsule?

I have a Time Capsule set up with AirPort and it works well for backups. Can I buy a second Time Capsule and plug it into this TC with ethernet and use it as an external drive?

jshafer wrote:
So, you are recommending using a USB drive into the TC or using an NAS plugged into the ethernet port...is that correct?
Yes, correct. USB drive is not fast but it is still mostly going to be faster than wireless.. it is of course slower than ethernet.. so what you are using on your clients dictates what is the rate determining step of the network.
Am I correct in thinking that an NAS using ethernet connection would be faster than USB?
Does a true NAS have its own internal backup system?
Yes, to both.. but remembering the client has to be able to make use of it. ie is also ethernet.
True NAS is faster than TC as they use RAID systems.. more reliable.. you can replace disks in the raid.. TC is sealed.. and all decent NAS will be able to back themselves up to a USB drive.. on incremental basis.. which is major shortcoming when people try and use the TC in this role.

HT1665 how come i cant use other headphones or external speakers with my ipod

how come i cant use headphones or external speakers with my ipod.sood as you plug either in there is no sound.

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Check also Settings > General > Accessibility > Hearing. Make sure that the sound balance is not set all the way to "R".
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.
Apple - iPod Repair price
A third-party place like the following will replace the jack for less. Google for more.

Using external drive with iMac as startup

I have an iMac that the hard drive is failing thus I purchased an external drive to use as a startup up drive connected to the iMac. How reliable is this setup and what are the cons/pros in operating this way?

Assuming you bought a FW800 drive the performance should be OK, not as good as your old internal HD but useable. If you bought a USB drive the performance is going to be very slow. As far as reliability it should be fine assuming you bought a decent quality HD. However why not just get the internal HD replaced? If you decide to move forward with the external HD after you install OS X onto it don't forget to make sure it's set as your Startup drive in System Preferences.

Using external mic with iMac 27 i7 under bootcamp with Windows 7

Hi,
I've recently got myself an iMac 27" with the i7 upgrade. I'm running Windows 7 Professional 32bit for gaming (Snow Leopard for everything else). I have a headset with two 3.5mm plugs, one for the headphones, one for the mic. I can't get the mic to work (headphones work fine though). I plug it into the line in port (as it's the only other port when the headphones are plugged in) but this doesn't work.
Does anyone know how to get this to work?
I read somewhere that the headphone port on the iMac is a "triband" port, so would work with the headphones provided with the iphone that have 3 bands on it (stereo sound and mic) or something similar...

Two things to try, first make sure your Win7 disk is spotlessly clean, my superdrive regularly spits out even slight smudges. then if that doesn't clear it up here is a maintenance tip with the reset:
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Problems formatting external drive with Disk Utility

Hi all
I'm having some odd troubles with using Disk Utility to format an external hard drive. For some reason, it is giving me all sorts of errors and problems.
Currently, it will let me format the drive in MS-FAT, but won't let me copy certain files to it (it gives an error code). I'm currently trying to re-format the drive in Mac OS Extended (Journaled) but the status bar give me the following error and continues to do its 'pondering' instead of giving me a progress bar:
!http://img19.imageshack.us/img19/5019/picture2csm.png!
It is currently sitting like that, not doing anything (not even going unresponsive).
What am I doing wrong here?
Cheers.

Wait, scratch that, it suddenly started working again.
For some reason, I had to partition it, with one partition a Mac OS partition and the other an MS-DOS FAT... hey ho, no idea.

Format External Drive with Disk Utility, Make it Windows Compatible

I have formatted my external drive using disk utility, and it works great on my Mac. But no Windows PC can read it, and I need to use it on Windows PCs. I tried formatting as MS-DOS FAT but that didn't work either. What can I do?
Thanks so much in advance.

I've run into the problem fairly regularly were I format a drive as FAT32 on the Mac, but Windows won't read it. I just reformat it from the Windows machine as FAT32. My Mac always reads and writes to it just fine, so it has never been a problem, just a minor mystery.

Can you really not use a windows-formatted hard drive with Time Machine?

I still have people in my household that think Windows is the way to go, and so they have used all the hard drives to back up their stuff.
There is still a reasonable amount of room on one of the hard drives for me to do a Time Machine backup, however it is obviously formatted to Windows.
Is there ANY way the hard drive can be used with both systems?
It's a bit of a bummer if I have to shell out for a new one just for my MacBook!
Thanks

Do you mean you want to connect a USB drive to the TC? If so, it will recognize a disk formatted in FAT32, but not ExFAT or NTFS.
If you mean you want a Windoze-like partition on the TC's internal HD, that's a bit trickier, since it can't be partitioned. But you could create a disk image on it via Disk Utility, formatted MS-DOS (FAT) aka FAT32, or ExFAT (I'm not entirely sure if ExFAT would work in a disk image there, but it might.)

Automatically mount USB 3.0 WD External HDD with iMac 24-inch mid-2007

I am using a 2TB Western Digital (WD) My Book Essential external Hard Disk Drive for my iMac 24-inch mid-2007 to use it as a Time Machine backup disk. This HDD only comes with a USB 3.0 connection.
Function-wise, it works with the iMac and Time machine uses it for backup without any issues.
However, the following problem occurs at every restart: the HDD does not mount automatically. And Time Machine stops backuping. To make it work again, I have to either unplug/replug the power cable of the HDD or unplug/plug the USB cable of the HDD so it mounts again and can be used by Time Machine. When unmounted, I tried to see if the disk was at least visible in Disk Utility so I could mount it from there but it does not appear in Disk Utility until I physically unplug/plug it back again.
For troubleshooting purposes, I have tried to use this HDD with my MacBook Pro Retina 2013 and I don't have the same problem as the HDD mounts itself automatically when I restart.
So I assume the problem reside in the way the iMac mid-2007 handle USB 3.0 as it was probably manufactured before the USB 3.0 standard was developped.
Would anyone know a possible workaround for this issue? I don't have too many hopes but one never knows...

I am using Mavericks 10.9.1.
The problem was also occuring when I was running Mountain Lion.
It looks backward compatible to me except when it comes to automatically mount itself after a restart.

Suggestions for formatting external drive with bad block?

I have a OWC Mercury 300 GB external drive. I wanted to erase it and use it as a backup for one of my laptops. The drive had been working fine as a Time Machine back up for an old (intel) iMac. I told Disk Utility to erase and reformat. It erased, but refused to reformat saying there was a bad block on the drive. Now Disk Utility recognizes the external drive but won't do anything with it. No Verify. No Repair. All grayed out. Any suggestions?

I wasn't a hard error, that's why. Repartitioning and reformatting will often fix soft errors in the directory structure. Had there been a real, new, bad block on the drive it would not be repairable. A soft bad block error can be fixed by reformatting. The hard block error may be fixable by using Zero Data one pass that may spare out the bad block. But if none of that works then you need to replace the drive.
You were fortunate that the error probably was spurious and resolved by repartitioning (may have been in the disk's RDB.)

Using Superdrive as an external burner for iMac

I have an iMac flat screen (OS 10.4.6) Combo drive and an iMac (OS 10.2.8)with a SuperDrive. Can I use the older machine with the superdrive as an external drive for the newer machine?
iMac Flat Screen Mac OS X (10.4.6)

On your iMac flat screen you could use iDVD to make a disc image. Copy the disc image to your older iMac and use Disk Utility on that iMac to burn the DVD.

Why is there large used space after erasing external drive with disk utility?

I just used disk utility to erase a 2 TB external hard drive. After erasing it, it shows that the disk has 12 folders, 62 files, and 852 mb of used space. I thought the "erase" function is supposed to format the disk? Where does the large used space come from?
By the way, the disk used to formatted as a windows disk. I suspect it has something to do with it but have no idea what. Any help is greatly appreciated!

HI - i do not think this is purely metadata. (though it could be with your windows disk with such small used memory) i have a 1TB macbook pro drive that i have tried to reformat
METHOD 1 (recommended by advanced Apple Techy) - select hard drive (not partition) select mac os (journalled) and press 'apply' - "this will format drive removing all data. it is always best to work with the drive and not partition, if you are formatting an entire drive."
result at end - drive still shows single partition 999GB WITH 668GB USED
METHOD 2 (after response from Apple techy) - select hard drive and mac os (journalled), press secure erase and select 'write zeros' takes 12 hours
result at end - drive still shows single partition 999GB WITH 668GB USED
