You need at least two complete backup sets, as invariably backups do fail. The more you insist of transferring data around the disk and data pathways of the computer (and the less reliable low speed buses used by many external hhds) by needlessly defragging, the greater the danger of data loss. I have 500 GB drives I top off to 450 GBs or more with no issue. what is on my ext drvs i put too much ofĪ value on them to take a chance on loosing the data. To it, you could find the drv freezing up on you with no way to getĪny of the files. Back up hhds aren't for general data usage, if your constantly updating the data on the drive by adding to existing folders and files, that's another issue altogether, and fragmenting will occur in that case.Īnd if you go to the 100% mark or very close They transfer just like that, as one big block that normally has no fragmentation what so ever. I transfer 230 to 600 GBs chunks of data a couple times a month. There's no point to defragging a large set of data files that are copied as back ups to a hhd as they won't be fragmented to begin with. Run youir drvs, internal or external, that way be my guest.

To backhawk13- if the drv is used for backup then it still should beĭegragged, as it is used and reused it is going to slow down and theįiles get put all over the drv. In any event, i use diskkeeper2008 to automatically defrag all the drvs all the time. what is on my ext drvs i put too much of a value on them to take a chance on loosing the data. and if you go to the 100% mark or very close to it, you could find the drv freezing up on you with no way to get any of the files. if you want to run youir drvs, internal or external, that way be my guest. To backhawk13- if the drv is used for backup then it still should be degragged, as it is used and reused it is going to slow down and the files get put all over the drv. if you buy a 500gb drv then you will find that after intallation that it has about 465gb available. the figure i am mentioning is real usable space, not the advertised space or the space quoted on the box.

the 30gb file is bigger than the 20gb of free space.

if you have a real capacity of 100gb and it is 80 gb full and you try to degfrag and one of the files is 30gb then it is not going to work. How much space you nned is dependant on the tjhe size of the file the defragger is trying to move.
