After having my 1TB G-Tech G-Drive Q desktop external h.d. crap out on me for a second or third time, this time for good, I give up on G-Tech. (I also had a faulty 500GB G-Tech portable which had to be replaced.) For many reasons, my iMac's Time Machine backups have to be stored on an external hard drive rather than on our Time Capsule. Two or three times in the past year or so, the external h.d. has become corrupted or something and has had to be reformatted, losing all the previous backups and starting all over again. This time, since the external h.d. is toast, I have no backups at all. My MAIN question: Do any of you have a recommendation for an external hard drive - probably desktop, but not necessarily - preferably 1TB - which is RELIABLE? Is this h.d. corruption/repeated failure a function of Time Machine? The hard drive itself? What good is Time Machine if I lose my backups all the time?
