patronu Posted October 10, 2010 Share Posted October 10, 2010 Is it posssible to use diskpart to move a partiton or to shrink it from left? Currently diskpart shrinks the partion only from right side. So this sucks. Link to comment Share on other sites More sharing options...

jaclaz Posted October 10, 2010 Share Posted October 10, 2010 Hard rives USSUALY work like this:Data stays near the inner circle of the drive where read times are faster, free space stays on the outside. (Untill the drive fills up)Any reference to backup this statement? (Last time I checked outer tracks were WAY faster than inner ones , and data was allocate form the outside to the inside )http://www.pcguide.com/ref/hdd/geom/tracksZBR-c.htmlhttp://www.tomshardware.co.uk/forum/244351-14-partion-hard-drive-performancehttp://www.cs.berkeley.edu/~kubitron/courses/cs252-F00/lectures/lec20-disks.pdfjaclaz Link to comment Share on other sites More sharing options...

jaclaz Posted October 10, 2010 Share Posted October 10, 2010 WOW I am totally wrong!I am very sorry I am so ashamed.No need to. Hard disks and optical media work differently and you probably thought to estend your experience with CD/DVD's to actual hard disks....jaclaz Link to comment Share on other sites More sharing options...
Tripredacus Posted October 11, 2010 Share Posted October 11, 2010 Is it posssible to use diskpart to move a partiton or to shrink it from left? Currently diskpart shrinks the partion only from right side. So this sucks.It is typically a bad idea and/or not supported to change the first sector of a partition. This is why Diskpart doesn't do it. Some other programs might, like Partition Magic, but I never tried it. The problem comes down to having to totally rebuild the FAT because you end up bit-shifting everything in the partition. I might be wrong (wouldn't be the first time) and Jaclaz can correct me (wouldn't be the first time) Only one way to learn! Link to comment Share on other sites More sharing options...
patronu Posted October 11, 2010 Author Share Posted October 11, 2010 all programs like acronis, gparted can do this. so why diskpart can't? Link to comment Share on other sites More sharing options...
jaclaz Posted October 12, 2010 Share Posted October 12, 2010 (edited) all programs like acronis, gparted can do this. so why diskpart can't?Also Adobe Reader, Paint and Excel cannot. Which kind of question is it?A program is either designed to do something or it is not.And yes, our k-martian legend does have some misconceptions.... but it would be too lengthy to do a full immersion course about partition structures and filesystems and most of the related things, default sizes of FATs, etc. are either UNdocumented or misdocumented.Even Partition Magic and Acronis apps in some versions were not reliable, and judging from the amount of versions of the various Linux based partitioning/resizing tools, even them have their quirks.In a nutshell, if you want to be 100% safe DO NOT trust ANY partition resizing/moving program, it is much safer to backup, delete partition, create new partition and restore data.Even a MS original tool like CONVERT may create problems... :http://redmondmag.com/articles/2004/01/01/build-a-better-ntfs-converter.aspxjaclaz Edited October 12, 2010 by jaclaz Link to comment Share on other sites More sharing options...
