thumpa Posted April 5, 2009 Share Posted April 5, 2009 Hii alll could anyone tell me please on how long it roughly takes to defrag 180gb of data? my external HDD hasn't been defragged for a while now.. soim defraging them. Link to comment Share on other sites More sharing options...
Kelsenellenelvian Posted April 5, 2009 Share Posted April 5, 2009 Depends on the prog you are using, the rpm of the external disk and the cache size of the drive...Plus the amount of defragmentation.Shouldn't take too horribly wrong though. Less than an hour for sure. Link to comment Share on other sites More sharing options...
thumpa Posted April 5, 2009 Author Share Posted April 5, 2009 cheers dude, program im using is Diskeeper 2007 and operating system windows xp pro 32bit Link to comment Share on other sites More sharing options...
Ponch Posted April 6, 2009 Share Posted April 6, 2009 Depends on the prog you are using, the rpm of the external disk and the cache size of the drive...Plus the amount of defragmentation.and also the % of free space on the partition(allowing the program to move bigger chunks of data at the same time).

PC_LOAD_LETTER Posted April 7, 2009 Share Posted April 7, 2009 but really thats like asking "how long to clean and rearrange a 10 x 10 room?" It totally depends on what in the room(whats on the drive), how large the furniture is(how big the files are), how fast you move(read/write speed), how much you can lift without getting winded(cache), and how much free space is in the room(free disk space).

CoffeeFiend Posted April 7, 2009 Share Posted April 7, 2009 ...and also how fast is the app doing the defragging, and what settings (how thorough) one uses, how fragmented it is in the first place and and so on. Besides, over USB it'll take longer. Could be 5 minutes, could be 5 hours. Link to comment Share on other sites More sharing options...
minotaur Posted April 7, 2009 Share Posted April 7, 2009 Yes, defrag times are highly unpredictable. Some of the variables are-speed of the drive itself-volume of fragmented files-size of the fragmented files (moving larger files obviously takes longer)-type of fragmented files. eg ...system files like the page file (and MFT for most defraggers) cannot be moved online, and they also form barriers to other file movements.-disk activity from other applications-CPU usage-fragmented free space-available free space.-and very importantly, the defraggers algorithms. Some are clearly faster than others.So predicting defrag times is a hit or miss affair.That said, I use Diskeeper 2009 Pro on my XP machines, and it's always left on auto defrag (defrags only in the background using idle cycles) so defrag times are not an issue for me. It's a great set and forget solution.BTW, defragging an external HDD will take a long time because of the slow USB interface that is much slower than the internal IDE/SATA standard, so expect long defrag times. Another factor is that unless the external drive is heavily fragmented, the USB interface is more likely to be the bottleneck than anything else.

Ponch Posted April 7, 2009 Share Posted April 7, 2009 Some programs will also move all your files, moving choosen ones closer to the beginning of the drive. That takes far longer than just defragmenting or consolidating free space. Link to comment Share on other sites More sharing options...
Arrow22 Posted April 10, 2009 Share Posted April 10, 2009 Keep in mind that the average life expectancy of a hard drive is 5 years.Whenever you defrag, you shave about 3 months use from that drive. Link to comment Share on other sites More sharing options...
CoffeeFiend Posted April 10, 2009 Share Posted April 10, 2009 Whenever you defrag, you shave about 3 months use from that drive.[Citation needed]In fact, most studies say otherwise. A few minutes of higher usage doesn't really put any extra wear on it (it's made for it, they're not meant to sit idle 100% of the time), which will reduce seeking a lot afterwards (less work after). Companies even advertize this, e.g. diskeeper claims "extends hard drive life spans" (and they don't make profit from replacement drives either), and they're not alone saying this.

Arrow22 Posted April 12, 2009 Share Posted April 12, 2009 (edited) No Disrespect Is Intended...I was going by my personal experience.Been doing this well over a decadeMaxtor has been the worst.Most defrag companies will not state that thier programwill lower the life expectancy of a drive.Defrag usually lasts much longer than a few minutes.If it is that short a time, Drive probably does not need it.Here is a nice discussion on itThis info does not count for win98 and lower OSsOnly the Newer OSs where most software is composed of MANY files that are located everywhere anyway.<>A real good article from Cnethttp://news.cnet.com/8301-13880_3-9887297-68.html Edited June 15, 2009 by puntoMX Link to comment Share on other sites More sharing options...
