Guys, I'm trying to use Carbon Copy Cloner. In order to do so, I formatted one of my partitions on my external hard drive into Mac OS Extended (Journaled)... it's 300 GB... so that would be more than enough, I reckoned. However, CCC gives me this warning: 'You may have difficulty booting from this target volume, the underlying disk is not formatted with a partitioning scheme that Apple recommends for Intel Macs.' What does this mean? Should I continue anyway? Or will it be an useless clone? Does this mean I have to have a 'clean' external HDD for this job? Regarding the Drobo... I installed it in Windows, when setting up I could only choose to format in NTFS or FAT32. I chose NTFS, but then went to My Computer and reformatted it to exFAT... Now the Drobo Dashboard doesn't recognize the file system and says it's unformatted. I can use it perfectly though... But when trying to get to the data on my iMac, I was unhappily surprised... Although the Drobo Dashboard does show the Drobo, I can't find it in Finder... It is visible in Disk Utility... but it's greyed out... Does anyone have any idea how to get into the Drobo data? And could it be possible to make another partition on the Drobo for the CCC clone? Or would I get the same warning again?
