Apple photo editing. Definitely, Photos must be included among the best photo editing software for Mac. On the downside, many Apple fans have criticized the absence of some features, which were available in the previous iPhoto and Aperture. Overall, this powerful and intuitive tool, has been designed with the modern-user needs in mind: great integration, easy editing, and professional photo management tools. Want to format a hard drive for Mac and PC compatibility? You have to set it up correctly before getting starting. Mac OS Journaled is the formatting option for Mac and NTFS or MS-Doc is the formatting option for PC. But to get a hard drive to be compatible for both Mac and PC, you have to choose the exFAT formatting options. Fat32 is another option, but it limits file transfer to 4GB, so choose exFat when formatting your drive. For Mac, format your drive under disk utility. For PC, format your drive under disk management. My favorite portable hard drive! Thank you for watching video!

How to format internal and/or external drive to work properly on Mac and Windows computers? Introduction; Which file system to choose FAT32 or exFAT? There is a solution, however, exFAT. Unlike FAT32, exFAT doesn’t have a maximum file limit. Better still, it can be read from and written to on any Mac running Mac OS X Snow Leopard or later and on Windows. To format a USB drive in FAT32 or exFAT: 1. Plug the USB drive into your Mac. Go to Applications>Utilities and launch Disk Utility. You should first understand what Allocation Unit Size (AUS) means. Memu. It is the smallest data block on the disk. Your actual data will be seperated to those units while saving to the disk. For example, if you have a file sized 512KB and you have 128KB allocation unit size, your file will be saved in 4 units in the disk ( 512KB/128KB). If your file's size is 500KB and you have 128KB AUS, your file still be saved in 4 units in the disk because as mentioned above 128KB is the smallest size of an allocation unit. 384KB will be allocated in 3 units and remaining 116KB will be allocated in another unit. You can observe this behaviour on file properties screen on Windows, what is your file size and how much space this file actually covers on the disk. And the operating system reads only that AUSd much data at a low level disk read operation. Those being said, using large AUS significantly reduces the free space utilization due to not using the last allocation unit completely. And as a side effect, the number of files to store on the disk is reduced due to same problem, last AU not being used fully. But, here's the trade-off, using large AUS, significantly again, improves the disk reading performance. The O.S can read more data at one read. Outlook for mac sync with iphone. Imagine, O.S makes couple of disk reads to completely read a GB sized file! ![]() Using small AUS improves the free space utilization but reduces the disk read performance. Think using large AUS in reverse, same category problems and improvements, but in reverse. So, what is the conclusion here? If you will store large, I mean 'large!' , files on the disk, higher AUS will give you appreciable read performance while reducing the file count and free space. Which AUS you should use? This depends on how much your average file size is. Also you can compute the free space utilization according to your file sizes. There are no significant storage overhead at high levels. Besides there is enough hrdw overhead since the actual physical sector size is 512Bytes. There is a part of file system formatting that records the cluster information, from how many sector this cluster is created, to the partition structure. The sector size emulation is a job of disk driver. File system server should deal with logical organization (NTFS, FAT etc) at high level O.S ops, smallest unit reads/writes at low level O.S ops and disk driver itself must work back to back with controller(hardware) for low level hardware. – Apr 27 '12 at 3:33 •. N sized units, M number units, N*M capacity disk, 'what is the probability of hitting this unit?' And remember, disk has to be more precise in locating the beginnings of the units.
