And one of them is likely to be corrupted. You can check them one by one in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk. Partitioning of disk drive enables us to perform several different tasks such as change separate disk volume format or installation of multiple OS.

Now click OK. When you restore volume to another volume, it will make an exact copy of the original. Please note that this will erase the destination volume data. So, before proceeding, make sure that you are saving any files on a different volume.

ExFat should basically only be used on drives that need to work with both Windows and macOS computers. The format dates back to , and was made by Microsoft to provide some of the cross-platform compatibility of the older FAT32 format without the file and partition size limitations. Sure, you could read a Mac formatted drive on Windows or read a Windows formatted drive on a Mac , but both solutions either cost money or are unstable.
So despite the disadvantages, ExFAT is your best option for cross-platform hard drives.
There are nearly as many ways to format a disk as ways to skin a cat. Each has …
To be clear, you can use capital letters in file names either way. Case Sensitivity mostly determines whether the file system sees capital letters as different. The file system sees the file names as identical, even if they look different to you. Presumably, a case-sensitive file system was just seen as less user-friendly. Today, enabling case sensitivity could break some Mac apps that expect a case-insensitive file system.
The main downside is that forgetting the encryption key means losing access to your files. Sep 8, AM in response to hpr3 In response to hpr3. I don't know what case-sensative does, I was just trying to see what each exactly format option is more compatible with a PC platform.
Sep 8, AM in response to mllymel In response to mllymel. The upshot, as previously mentioned, is that none of the Mac OS Extended verisons, whether journaled, case-sensitive, encrypted or not, will work on a Windows machine without additional software. Windows just doesn't natively read Mac OS Extended volumes. Right, but no one, at least not I, suggested using FAT. FAT has little place in modern disks, it's mostly used for legacy reasons, and for small volumes such as flash drives. This is an extended version of FAT that is cross-platform compatible and avoids many of the limitations of FAT - at least as far as file sizes and disk sizes are concerned.

A caveat with case-sensitive file system is that not all applications work properly with them, including a number of Apple applications. Nor the Adobe suites. They will even tell you when you start installing the software that the drive you're putting the software on is case sensitive and must be changed before you can install and use Adobe's software.

My feeling on using case-sensitive file system is to only use them when you are forced into using them because nothing else works. I am having exactly that problem with rebuilding iPhoto libraries that aren't functioning properly. My external drive already has on it my Time Machine backups and my iPhoto library backups which I need to keep till I get my issues with that application resolved.
Looking at Disk Utility, it seems that changing the format of the drive would erase my data. Is that so? The iPhoto files are too big for my hard drive, so this would mean I would have to purchase another external drive to save my data. Sep 6, AM. You really should start your own thread rather then tagging on to a thread that has been dead now since last year.
Probably the only reason I even saw this was because I posted it on prior so it popped up for me to view. That's the single exception. If you let Time Machine format a backup drive, it will use case-sensitive, just as it will make a case-sensitive sparse bundle disk image for a network backup. The apparent reason is, if the backups are case-ignorant, and at a later date you decide to add a case-sensitive drive to your system and want Time Machine to back it up, too.
But if the backups are case-sensitive, it can. See E7 in Time Machine - Troubleshooting for the exception. Bottom line -- if you ever have to get a new drive and start over, use case-ignorant. But you won't be able to copy the case-sensitive backup set to a new TM drive and continue backing-up to it. You can, however, still access the old backups via the Browse Other Backup Disks option, per E2 in the above link.
Sep 7, AM. Since I always format the disks before use and never let the formating be done by an application, I was not aware of this exception of Time Machine formating to Case-Sensitive. I learned something today. Jan 8, AM in response to mllymel In response to mllymel.
