View Full Version : File copying problem

May 28, 2013, 12:36 PM
Hello everyone,

Finally I purchased an iMac 21.5" with i5 2.5 GHz, 16 GB Ram and 500 GB HDD.

I bought it two weeks ago and trying to figure out how to use it. So I need your help about an issue.

My friends came here with his USB stick and plugged it to the iMac. I was able to copy the files from his USB to my computer but I couldn't copy anything to his disk. Also I tried to connect my own HDD and I couldn't copy to that either. They are all NTFS and I have no idea how to copy files to the discs. Should I install a program for this? Can anyone help me solve this issue?

Thanks in advance,

Overview of the four major file systems (called "Formats" in Mac OS X) used on Windows and Mac OS X, compiled by GGJstudios (http://forums.macrumors.com/showpost.php?p=14053155&postcount=2). You can use Disk Utility (http://Pondini.org/OSX/DU.html) to format any HDD to your liking.

Any external hard drive will work with PCs or Macs, as long as the connectors are there (Firewire, USB, etc.) It doesn't matter how the drive is formatted out of the box, since you can re-format any way you like. Formatting can be done with the Mac OS X Disk Utility, found in the /Applications/Utilities folder. Here are your formatting options:

HFS+ (http://en.wikipedia.org/wiki/HFS%2B) (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)

Read/Write HFS+ from native Mac OS X
Required for Time Machine (http://support.apple.com/kb/HT1427) or Carbon Copy Cloner (http://www.bombich.com/) or SuperDuper! (http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html) backups of Mac OS X system files.
To Read/Write HFS+ from Windows, Install MacDrive (http://www.mediafour.com/products/macdrive/)
To Read HFS+ (but not Write) from Windows, Install HFSExplorer (http://www.catacombae.org/hfsx.html)
Maximum file size: 8EiB
Maximum volume size: 8EiB
Mac OS X: Mac OS Extended format (HFS Plus) volume and file limits (http://support.apple.com/kb/HT2422)
You can use this format if you only use the drive with Mac OS X, or use it for backups of your Mac OS X internal drive, or if you only share it with one Windows PC (with MacDrive installed on the PC)

NTFS (http://en.wikipedia.org/wiki/Ntfs) (Windows NT File System)

Read/Write NTFS from native Windows.
Read only NTFS from native Mac OS X
To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (http://www.paragon-software.com/home/ntfs-mac/) (approx $20) (Best Choice for Lion)
For 32-bit Mac OS X, install NTFS-3G for Mac OS X (http://macntfs-3g.blogspot.com/2010/10/ntfs-3g-for-mac-os-x-2010102.html) (free) (does not work in 64-bit mode)
For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard (http://www.offthehill.org/articles/2010/12/31/macfuse-for-64-bit-snow-leopard/)
Some have reported problems using Tuxera (http://www.tuxera.com/products/tuxera-ntfs-for-mac/) (approx $36).
Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
AirPort Extreme (802.11n) and Time Capsule do not support NTFS
Maximum file size: 16 TB
Maximum volume size: 256TB
You can use this format if you routinely share a drive with multiple Windows systems.

exFAT (http://en.wikipedia.org/wiki/Exfat) (FAT64)

Supported in Mac OS X only in 10.6.5 or later.
Not all Windows versions support exFAT. See disadvantages (http://en.wikipedia.org/wiki/Exfat#Disadvantages).
exFAT (Extended File Allocation Table) (http://en.wikipedia.org/wiki/ExFAT)
AirPort Extreme (802.11n) and Time Capsule do not support exFAT
Maximum file size: 16 EiB
Maximum volume size: 64 ZiB
You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

FAT32 (http://en.wikipedia.org/wiki/Fat32#FAT32) (File Allocation Table)

Read/Write FAT32 from both native Windows and native Mac OS X.
Maximum file size: 4GB.
Maximum volume size: 2TB
You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
