most fail in the first 3 months, another good amount in the first year, and then a good amount in the 5+ years mark. Google confirmed what most customers were seeing.

then do a full format and put it to use (if it survived thus far) leave it running a few days (or at least 1 day), perhaps running a burn in program. put a bunch of stuff on it, really fill it up. Specifically, starting over using an eSATA port. Note that there is absolutely no ill effect to simply aborting the format and starting over. drives tend to break very early and very late. it helps to give it a good "burn in" to help cull out the weak. filling it with 0s will find defective sectors (which it shipped from the factory with, it happens) and mark them as such.ģ. remember when the ipods were being shipped with a virus?Ģ. there have been (rare) cases of drives coming preloaded withs stuff. How much fun do YOU think it is, diagnosing and then replacing a failing hard disk drive in your computer? I’d much rather replace my drive because it is full, than replace it because it makes my computer crash when it corrupts my data.1. If I thought this were overkill, I wouldn’t do it. If you really didn’t need to read this post, you may be interested in using GParted and Clonezilla to copy your old drive’s data over to the new drive, and they are also both built in to the Parted Magic operating system which can be launched from your USB thumb drive or a CD/DVD appropriately loaded with the UBCD. So now, very nearly a week later, you will be ready to use your multi-terabyte drive. Its got about 250gb worth of storage and ive filled up about 230gb worth of that. This step takes a long time, and when you are done you will have a drive ready to use and worthy of your trust. Question: Q: How long does it take to reformat, erase all content on my hard drive I plan on selling my Mid-2010 13' MacBook Pro. Make this a Full format and just leave the settings on their defaults.

Install the hard drive as a secondary drive in a computer that already has a known-clean working Windows installation, and format the new drive.This should pass with flying colors if DBAN was successful in wiping the drive.
If you suddenly have a bunch of reallocated sectors, the drive is going to fail soon. GSmartControl conveniently highlights these in pink-to-red tones depending on severity of failure. If any of the more worrisome numbers increases, that’s a problem. Launch Parted again and re-examine the SMART data.The DBAN procedure erases all data on the drive and makes the disk useless until other steps are taken – and any viruses, including very sneaky ones, are VERY deleted. Two terabytes will take two-ish days, roughly. This takes anywhere from three to FIFTY hours or longer. Any failures are announced in the program.
This writes to each location where data can be written on the disk at least three times, and reads it to verify each time. Load Darik’s Boot and Nuke and “autonuke” the drive.(update: I ran the Long test on a pair of SATA-connected 3TB HDDs and they each took about 8 hours) I have seen many drives pass short and fail long tests, so yes I do both. So far we are from one to three hours into testing. If both these pass, run a Long Self Test. Still in the GSmartControl program, run a SMART Short Self Test and Conveyance Test.In El Capitan, Disk Utility looks slightly different, as you can see below. What Disk Utility looks like in Lion through Yosemite. Fire up Parted Magic and look carefully at the SMART data in GSmartControl (the Disk Health icon on the desktop) Any reallocated sectors at all, and the drive is rejected for any critical applications Then proceed to highlight your computer's hard drive select the Erase tab, make sure OS X Extended (Journaled) is selected, then hit the Erase button.Boot to the Ultimate Boot CD, which has a zillion useful tools built-in, including everything (but Windows) I discuss below:.Install the drive in a ‘kick around the shop’ spare computer and apply power, listening closely for bad noises.In fact, my usual testing for new hard disk drives is as follows:
Don’t transfer all your family photos and then watch it (figuratively) go up in smoke. Make those few hours during testing, instead of during use. It is an unfortunate fact of life that a HDD you get brand-new from the manufacturer has a non-zero probability of dying immediately or within a few hours of use. This requires time, and no two ways about it.Ī ‘quick’ format will take only a few minutes, but for a new drive I would not recommend saving the time. It takes so long because the computer is looking at every. Over a USB 2.0 connection, my drive took about 26 hours. In the computer, permanently (or temporarily) connected to a SATA cable, budget 5-7 hours. To do a ‘full’ format on a 2 terabyte hard disk drive in Windows, it will take a long time.
