I think they all make fine drives, but I have only purchased hard drives in retail packages so I know they were shipped properly. Sometimes those NewEgg drives that come from OEM boxes of 20 are thrown in a box with a single sheet of bubble wrap and handed over to UPS to throw around some more

For desktop/home use... I find it better to purchase drives with 5 year warranties than ones with 1-3 year warranties. I have had multiple Western Digital desktop drives with 3 year warranties fail over the years sometimes, sometimes right after the warranty ended, and sometimes early in their

Are you sure its a hardware problem? I would test the drives before condemning them. Is it something where the drive is going to sleep because of inactivity? On Sat, May 19, 2012 at 10:43 AM, Brian Toscano brian.tosc...@gmail.comwrote: For desktop/home use... I find it better to purchase

If you have a drive that is acting weird, I would run a test on it. If it fails, get it replaced while its still under warranty. Western Digital has free software that will read every part of the disk. It can take 5-7 hours for a 2TB drive if its connected with SATA/eSATA. I'd have to research

The answer to both is yes. They are perfectly compatible in both directions. As for drives, you have two choices: Consumer Enterprise You will pay probably 3x-4x more for the equivalent enterprise drive, depending on the vendor, but it will have a far better MTBF. It has been my experience

It could be, but the disk is a good starting point. For example, on my Mac Book Pro with an eSATA ExpressCard, I can NOT complete any lengthy disk tests without the tests stopping because of failure. It is something as easy as plugging in a USB device like my phone. Must be some interrupt
