    Default Defrag the nook

    I opened up Defraggler to take care of my computer and saw nook listed as a drive, too. Out of curiosity, I pressed "Analyze" and it reported 20% fragmentation. With all the copying, pasting and deleting I've been doing on it, I wasn't surprised. I tried looking up information on defragging ereaders and the closest I got was instructions on how to do so for Kindle. Someone there reported a way to reindex... I don't know what that means, but I haven't seen it raised as an issue for the nook's maintenance.

    Is it necessary or even safe to do this for our device?

    I defragged mine and it seems to be running a little better. I never would have thought about it. Thanks!

    I wondered that myself, and look forward to an answer.

    In the meantime, if I remember correctly, defragging a disk was meant to optimize disc seek where files are fragmented across a physical magnetic disk that the head need to skip around and find, thereby slowing down file access and retrieval. Since the nook does not use a magnetic disk, it's all stored in internal memory which is much quicker to access, I wonder if there is a point to defragging?

    Kevin, what utility did you use for defragging your Nook?

    I just used the windows defrag in the system tools.

    The term "index" on a Kindle refers to the process of indexing all the words in a book so that you can do a lookup. A Kindle begins indexing a book as soon as that book is placed on the device. I would assume that the nook indexes words in the exact same way.

    Interesting, I never thought to defrag flask memory figuring it has such a fast seek time. I did some poking around in the intertoobz and it seems this can have a positive effect.

    Not that I was doubting your perception but it did remind me of the days when I did auto detailing, many customers would call and ask if I did anything to the engine and I would ask why and they would reply that the car is running better lol. There's some strange distortion in perception when something is made to look better.

    I'm going to try this when I get home, I have a free book from the BN store called Hero Wanted and it's page turning at 4-5 seconds. all the others are fine.

    The memory in the nook available when you sideload is formatted in FAT32 (pretty sure about that anyway) so yes it will become fragmented over time.

    The Windows defrag utility is more of a joke than anything else, but it's better than nothing.

    If you google defragging flash memory, the consensus appears to be as follows:

    Flash drives don’t have a read/write head. In fact flash drives don’t have any moving parts. The flash drive’s electronics present the drive to the computer as a standard hard-drive by mimickery, but the data-storage is accomplished by so-called “flash-cells” which consist of a number of transistors each, rather than a set of spinning platters.

    Defragmenting a flash drive will get you very few, if any, performance increases other than perhaps a slightly increased write-time on certain drives. As there are no read/write heads to move, there is no additional time spent retrieving data from any separate flash-cells, no matter how far apart they may be. What defragmenting will do though is wear the flash-cells out faster.

    When a write is made to any given flash-cell, it causes a tiny amount of degradation in the components of that cell. This might not be true to such an extent much longer, as the underlying technology is constantly improving, but nevertheless, at present and probably for a long time into the future, it will be the case to some extent. The more you write to a flash-device, the shorter its life will be. Normal usage is OK; but it still won’t last forever. (What does?)

    Regularly defragmenting it unnecessarily, however, will add many thousands of write operations whenever you do it, and might even halve its lifespan.

    Defragment your electromechanical (standard) hard-drives regularly and it will improve file performance. Defragment a flash or SSD drive, though, and you’re just wearing it out for no good reason.
