Resolved Question

Network copy mac -> pc, Raid 5 (> 4gb filesize issue)

by Jan 24, 2015 6:17PM PST

I've installed a Raid 5 (with 5 disks) into a pc. Using Intel RST raid. I've formatted the raid with exFAT.

Now I've a lot of files on Mac computers where I want to transfer the files. The issue appears when files are over 4gb. Then I'm not allowed to copy the file.

Wasn't exFAT created for this issue? Already transfered over 2TB so don't want to format the drive.

Windows 8.1
OSX 10.10

Copy with osx finder samba.

thanks.

Re: big files

The first thing to check is if the target allows for files bigger than 4 GB. Just make one and see.

If the target file system allows such big files and transfer using samba doesn't, I'd use an external disk to transfer the files. You might need an add-on your Mac to be able to write NTFS files.

If the target filesystem doesn't allow it, you've got no other choices than reformatting to NTFS or splitting the files before transfer, but then you can't join them again, so that might be unpractical.

exFAT shrink?
by kidkic Jan 24, 2015 9:24PM PST

Thanks for the reply.

Tried to copy > 4gb file between drivers on the computer and that worked. So it has to be a Samba issue.

Also noticed that I cannot shrink my exFAT to make more partitions on the Raid drive. Will try to move all content and reformat the drive again.

Just takes a couple of weeks to move around 7TB *sigh*. Because there's no solution to shrink an exFAT today on Windows?
