    Time Machine
    Hello everyone,

    I got a western digital 500 GB HDD for time machine purposes but at the same time I wanted to use it for my other files like movies, music and stuff like that as I can't afford to buy another disk. Should I make a partition in that HDD or should I simply first let time machine to format the whole disk and keep files on the whole HDD?

    If you guys suggest me a partition then how do we create a partition on an external HDD?

    I'd really appreciate your help guys.

    You do not HAVE to use two partitions because Time Machine creates one folder containing all backups. If I am remembering correctly. So you can just put your other files there too.

    However it could be smart to partition it anyway. A good way of keeping control... you can partition the drive with Disk Utility. You find that application in the /Applications/Utility/ folder. It will work with external drives too.

    To further what Strukt said, TimeMachine creates what's called a `sparse bundle` which is basically a compressed, efficient binary image of it's backup meta-data/data etc. It is independent of any partitioning scheme so you don't have to create multiple partitions to use TM.

    Thanks a lot for your help guys. Yeah I saw the folder but I was just worried what if later on when time machine wants to back up, it replaces my other files and stuff with the backup data whenever the disk is nearly about to fill up rather than replacing the old backups?

    This is the main reason why I was concerned about creating a separate partition or not.

    Disk Partition
    Hello everyone,

    I wanted to create partitions on my external HDD of 500 GB (Western Digital)

    I want to create one partition for time machine and the other for the rest of my files. I have a 160 GB Hard disk in my Mac and since I don't need to back up my stuff very frequently so do you think creating a partition of 200 GB would be enough?

    I'd really appreciate your help guys.

    Thank you so much.

    A 200 GB partition will work OK. If you accumulate too many backups where Time Machine is beginning to run out of space, it will delete the oldest in order to make room for the newest.

    Regards.

    External HDD formatting and partition?
    Hello everyone,

    I got a Western Digital 500 GB external HDD almost 3 weeks ago for the purpose of Time machine as well as for my other files and important stuff. I created two partitions; one for time machine and the other one for my files.

    I recently went to a friend's place as he needed a few of my documents and it did appear on his PC that a new hardware is detected but didn't show any icon of the hard disk or anything like that. I'm confused about this and wondering whether the Mac formatted the HDD using its own format and which won't be compatible with windows but thats just my idea and I might be wrong.

    Since, I also have to use my HDD at times on a PC thats why I was wondering if anyone could help me out with this as the HDD only works with Mac systems and not PCs.

    I'd really appreciate your help and support people.

    Thank you!

    In order to use Time Machine with an external hard drive, it must be formatted to the OS X file system = HFS +. That file system can not be seen by Windows unless third party software is installed. You can partition your external hard drive into two partitions: One as HFS+ for Time Machine, the second as FAT-32 which is compatible with both Mac OS X and Windows.

    Regards.

    Formatting question.
    I have a 500 GB external HDD of western digital and want to create two partitions. One for the time machine and the other for my files and stuff. Is it possible to make the partition, which is for my personal files compatible for windows based system as well? If yes then that format would be MS-DOS (FAT) in the drop list? Just wanted to be sure if I take any step. I'd highly appreciate your help here.

    Thank you.

    You don't need to partition the drive but I don't know how well that will work because SuperDuper creates a bootable clone of your hard drive. The clone it produces is not the same size as that of the hard drive but just of the amount of data that is on your hard drive.

    Time Machine on the other hand will keep on making backups until it runs out of space and then it will start deleting them by date. (oldest first)

    Why do you want to use both? Either use SuperDuper to make your backups or Time Machine. I have Time Machine turned off because I prefer using Carbon Copy Cloner (same as SuperDuper) as my primary backup.

    Regards.

    thanks you basically answered my underlying question--Do I need both...I do not need to have archived backups to return to past work--- just a simple back up for photos and documents

    any reason that you like carbon clone over Superduper
