It found one minor error, which was corrected.įinally, around two days after I started installing my new 2 TB hard drives in the Promise Pegasus enclosure, I was ready to let Time Machine roll into action with its first 7 GB or so backup since earlier this month. Within a few seconds of asking it to change the partition size, the job was done without error or complaint.īelieving in belt and braces – and not wanting to increase my 2.4 TB of backups without confidence that they had survived this marathon migration intact – I then used Disk Utility to repair any remaining errors on the drive and then the volume. I was just about to resort to Terminal’s command line and the intricacies of its diskutil tool, when it occurred to me that Drive Genius 4 might be able to help. Disk Utility appeared unable to do the job. So I tried to repartition the drive again, waited several more hours, and got exactly the same error. That accounted for several more hours, at the end of which there were no significant errors found. I ran First Aid on the drive and then the volume. Operation failed…”Īnd that was that – all those hours, and an error right at the end stopped it from working.ĭespite the unusually fragmented English in that error message, I believed it too. If you recently grew your whole-disk, you should run whole-disk repair. At the end, I got the unwelcome snub that “MediaKit reports partition (map) too small. With 2.4 TB of Time Machine backups, and their dense links, to check, this last stage took several hours.

In theory, all you should have to do is open Disk Utility, select the drive (not the volume), click on the Partition tool, change the size of the Mac Extended partition, and click on the Apply button.ĭisk Utility then goes off, makes the change and – the bit that wasted so much time – then runs a full check on the drive and volume. But that last step took the best part of a day.
All I had left to do was to resize the Macintosh Extended (HFS+) partition to match the 6 TB now available. I had replaced the drives one by one, migrated the size of the logical drive to fill the resulting 6 TB (net), and it had all synchronised properly.

The saga to upgrade my Promise Pegasus R4 RAID drive just kept going.
