I stopped using iDefrag about 5 years ago. I have used iDefrag for many years and in truth I find no fault in the way it performs - mostly. I am not pleased with this developers idea of customer loyalty. I look forward to some help, as my work is halted until I finish defragging some drives, and I'm wondering if I need to budget 28 hours of computer downtime per 650GB of hard drive defragging :-| Model: Expansion Portable HDD (STEA4000400)Ĭonnection: Seagate's USB 3 Elgato USB 3ĪLSO - Regarding upgrading from iDefrag 1.7.3 to 2.2.8 (per Corialis website suggestion for OS10.9.5): Skip files that cannot be defragmented due to lack of free space: SELECTED/CHECKEDĬonnection: MacBook Pro ThunderBolt 1 Elgato ThunderBolt 2 I'm wondering: Does this mean I have another 14+ hours left to wait for this, and if so, is this normal/OK for iDefrag to take some 14-28 hours to optimize 650GB on a 4TB drive?!Įnable per-class sorting: SELECTED/CHECKED I recently upgraded my OS from 10.7 to 10.9.5, and I already had iDefrag 1.7.3 (229), which I'm using now.Īs we speak, I'm about 14+ hours into a iDefrag Optimize on a 4TB external drive that only has 650GB used, and the Location Indicator is only about halfway through the populated area of the Whole Disk Display. Hi MU community! I hope someone might be able to advise me here.
