On a MacPro 3.1 with Sonnet SATA PCI card and FANTEC eSata box / 4 HD in JBOD I faced constant unmount problems with usual Mac commands or using Disk Util (mostly HD sleep mode interfering). This little app makes wonders. Never a single HD hanging again. Ask Mountnuom to unmount all 4 HD or more together at any time. They will go steadily in a row without a hitch. Version 2.1 on SL 10.6.8
Great time saver...
I agree, menubar would be great and I'd gladly pay a small fee for that convenience.
Does anyone know if this is Snow Leopard ready? I just ordered a new Mac and it'll have SL.
