I have, over the years, noticed that bad hard drives are almost a thing of the past, and have begun to suspect that once the HD manufacturers run them through a QA test to detect defects the odds of a sector going bad are pretty darn slim.īut (and this is the actual question) I wonder if the bad sector info survives a format change from FAT (or FAT32, or exFAT, or newFAT) to NTFS. However, that doesn’t make me an expert on anything that’s happenning today, given the current rate of technology change, and given that I’m sitting on a sailboat at anchor and am an ‘inadvertant luddite.’ I remember paying $14,000 for a 400 MB hard drive. I too have been using computers for decades, cutting my teeth as a system manager on DEC VAXes. After much research, this is what I have come up with: This, of course, not only confuses the issue but also makes it pretty difficult to get a handle on. Unfortunately, many sources are still quoting the older information relevant to XP, even though they are discussing Vista/Win7. Pre Vista operating systems, including XP, handle the Quick Format in much the same manner but the Regular Format changed in Vista and those changes carried through to Windows 7. So I decided to research the subject and expand my knowledge in this area.įirst thing I noticed there is a heck of a lot of misunderstanding and misconception about what actually happens during a reformat much of which can be attributed to changes Microsoft adopted for Vista. Anyway, technology is not my forte by any means but I relayed what I knew in layman’s terms which satisfied my friend, but also made me realize my own understanding of the processes was pretty limited. First thing I should mention here is that we are talking about used drives, so ‘reformat’ is probably the more precise term. A few days ago a friend asked me what the difference was between performing a quick format and a regular format.
