Hi I am one of those people trying to keep Hard Drives out of the local landfill. A large number of the drives I see are formatted into two sections. One section is usually fairly small 20-100MB and the other section is the rest of +- 99% of the rest of the drive. Am I making a mistake by formating the whole drive as opposed to just formatting the larger portion of the drive or should I just go ahead and format the whole drive? I use these drives to build computers that I have that have no drives or else I sell them online. I hope this isn't a stupid question. Guilty as charged. I am just starting in this adventure. I use Hard Disk Sentinel, my computer management tool in W7 and I have quite a few other software programs that I have so far just played with. I am trying to build a computer specifically for this purpose with multiple drive bays both ide and sata and with ubuntu as the OS so as to be able to check out more drives at a time rather than one at a time. I actually have some of what I think are scsi drives from a server that I would like to test but that is a project for another day. Thanks for any information that you might be able to supply. And yes some day I would like to afford the real tools I think most of you use like the Atola Disc Recycler but that is way in the future.

I would zero-fill the whole drive and then perform a full surface scan with a tool such as MHDD. MHDD will identify any "slow" sectors. Finally, examine the SMART report with MHDD, CrystalDiskInfo or Hard Disk Sentinel, etc.

Thank you one and all. It looks like a fairly long and steep learning curve but I think I will give this a try. Is there an online web site that will give me a place to start my journey. I have retired from a long and happy career in an ancillary medical field and I guess my brain would like another challenge. I have no illusions of ever truly understanding computers in general and hard drives (storage devices) in particular but I would like to at least try. Any suggestions would be greatly appreciated.
