Windows Format Drive For Mac Extended
Besides, you can format an external hard drive for Mac and Windows by converting HFS+ to FAT32 or exFAT without losing any data. Step 1: Backup Data in HFS+ Partition on Mac. Just transfer all useful files out from the external hard drive to other devices on Mac. Of course, if you have a backup already, ignore this step.
Hi, I have the external drive formated as FAT of 1TB. I have erasing all data whole day (about 20 hours) and formating as Mac OS Extended (Journaled) but at the end it reports an error.
Now, when I connect hard drive to my MBP it says 'disk is not readable on this computer' - Initialize. When i try to format as Mac OS Extended (J) it says: 'Disk erase failed with error: File system formated fail' I tried to format it on PC (Vista and XP) but they even can't see hard disk. What should I do to get journaled formated external hard drive? Add outlook calendar to google calendar. Thanks in advance! I had the same problem. I bought a WD My Book 1TB hard drive and there was a problem with it formatting.
I wanted to use this disk for time machine as well as partition it so i had some miscellaneous storage space. This was my solution Try formatting the disk to FAT, this worked fine for me, at least now it can be seen and read by both windows and osx. Then I went into time machine and selected 'change disk'. It then prompted me and said that it had to erase the entire drive and reformat. The reformatting with time machine worked fine and the drive was then in mac format.
After it does that it starts to backup your drive, you can just cancel this and use the drive how you want. Or if you want to use it with time machine then let it do the initial backup.
Make sure you always have a drive with a time machine backup of your computer on it because if somehow you mess up your disk, you are screwed if you didn't back up. You have to change the drive from Master Boot Record to GUID (Intel) or Apple Partition (PPC).
Pretty much all drives not purchased at an Apple store will be MBR with a FAT format allowing it to work on both OS X and Windows, but MBR can't be formatted to HFS+ (Mac OS Extended) specifically for Macs. However, GUID works with HFS+ and FAT/NTFS partitions, as seen with BootCamp.
Although, that might just be a Mac specific thing, and if you want true cross compatibility it may need to be MBR/FAT. Otherwise: Disk Utility Select Drive from left Click Partition Tab Select 1 partition from pull down menu (or whatver you want, though this must be changed from 'Current') Click Options button Select your Partition Table, click OK Change format to what you want Name your partition Hop on one leg Dance in a circle! Click Apply Same deal if you want to store a 4GB+ file on a flash drive. They are all MBR/FAT and can't store such large files, so if you use a Mac you can format it to GUID/HFS for the transfer, and then can change it back with Disk Utility to MBR/FAT for normal use.
Sharing an external drive between a Mac and a PC under Leopard There are two ways to share an external drive, i.e. A FireWire® or USB 2.0 drive, between a Mac running Mac OS X 10.5 Leopard® and a PC running Microsoft® Windows®: physically or over a local network. Physically sharing an external drive If you have an external drive that you want to share between two locations, such as home and office, and have a PC at one location and a Mac at the other, then the best way to physically share the drive is: • Format the external drive in Mac OS Extended format: see the Disk Utility Help documents concerning partitioning a disk. Prior to reformatting the external drive, backup any data on it that you wish to save. • Install on the PC.
