I've had an iMac (which is my first Mac, other than a brief play with a Mac Mini) for about 6 months. It's been great, except in that time i've had three external hard drives fail, and a fourth is now giving me worrying signals!
Is there / could there be anything inherently wrong with my iMac to cause repeated failures, or am I just on a string of bad luck?
- First failure was a Western Digital Passport 2.5" USB drive - can't remember the details. Wasn't heavily used.
- Second failure was a Seagate GoFlex Firewire 2.5" drive - this one just one day disappeared from my drives, failed any self test, and couldn't be repaired. Found a PC to run diagnostics on, and it failed its SMART status check. Was always connected and always on, as a Time Machine disk.
- Third was a Samsung Story Station 3.5" mains powered USB drive - again, just failed one day without warning, all data was unreadable, though it would allow me to reformat and use it (for a short period of time, before the same thing happened again). Never had chance to run SMART diagnostics on this one. Was only ever briefly connected (once or twice a week) to run a backup, then turned off again.
- Fourth drive is another Seagate GoFlex, this time it's used as an offline backup so only occasionally connectrd. Hasn't failed on me yet, but has just randomly disconnected itself part-way through a backup a couple of times. No apparent data loss, nut it's got me worried and i've got a second backup drive on the way just in case!
Anyone elses experienced a high rate of external drive failures? Is there anything I can do to reduce them? OS X seems particularly bad at any kind of diagnostics, with no software available that I can find to read the SMART status of USB drives (other than for some specific manufacturers). All drives have been Mac formatted (journalled) - is another format more reliable / recoverable?
Any suggestions greatly received!
