Hi folks, You are my last resort before sending this unit back to seller. Here's the deal I bought a Macally enclosure with a 1TB seagate, model is G-S350SUA, it comes with 2 firewire and 1 usb. I am using a PowerBook G4 1.5 running mac osx 10.5.8. I connected everything using the firewire, it was recognized the first time no problem, I initialized the drive in mac journaled in disk utility, partitioned my drive in 2 and made a full back up of my system. Everything was smooth I ejected the drive as usual and then shut it down physically and disconnected everything. Now the drive do not mount anymore, I can hear the HDD but it does not appear on the dektop, nor the panel , dont see it in disk utility either. I tried the other firewire port and the usb...still no result, tried relaunching the finder, restarting the mac...still no result. Connected everything to a powermac G4 it worked the first time...but now same thing, it does not mount anymore. The ports on both of my mac are funtional, I have another drive, a lacie porsche and it works perfectly. I checked my powersupply that came wth my macally enclosure, it says 3A, and it does power up the drive...I am lost. I can not test the drive by itself as I dont have a mac that could accept a sata drive. Any idea people? The only info I could find on the net, was about the powersupply being not strong enough because it originally came with an output of 2A but I doubt it is my case, and the drive do spin, I hear it. Any idea people? Solution, is the macally enclosure malfunctioning?
