newmy51 Posted June 26, 2014 Share Posted June 26, 2014 -Gigabyte GA-Z87M-D3H LGA 1150 CrossFireX DVI/HDMI mATX Motherboard -Intel Core i7-4770K Haswell 3.5GHz LGA 1150 84W Quad-Core -16GB (2x8GB) CORSAIR Vengeance LP SDRAM DDR3 1600 (PC3 12800) -EVGA GeForce GTX 760 (4GB 256-bit GDDR5) -SanDisk Extreme II 240 GB SATA 6.0Gb/s 2.5" SSD -Pioneer BDR-209DBK 16x Blu-Ray/CD/DVD Writer -OS X Mavericks 10.9.3 Just a few months old, from Newegg: http://www.newegg.co...N82E16822145509 Disk utility sees the drive, but goofs on the partition ("disk2s1" should be entitled "Hitachi.") or disk utility recognizes the partition, but doesn't mount it automatically. Then upon right-clicking and mounting from disk utility, an error will come up saying the mount was unsuccessful, but the drive appears on the desktop and appears to work normally, despite disk utility not recognizing the drive as mounted. Rebooting and/or removing and reconnecting the drive sometimes helps. When it's good and recognized, every repair and verify Disk Utility check comes up clean, and I'm able to read and write as normal (with help from Paragon NTFS). Any and all help greatly appreciated. -newmy51 Link to comment Share on other sites More sharing options...
aphex6b Posted June 27, 2014 Share Posted June 27, 2014 Not sure if it is the drive / filesystem OR the external USB3 bus / driver implementation causing this. But maybe installing SAT-SMART usb attached SCSI driver or the alternative GenericUSBXHCI makes a difference. Link to comment Share on other sites More sharing options...
