Use Drive Compression on USB External (WD Passport)?

Has anyone used drive compression with an external USB drive like a WD Passport? The drive I'm considering compressing has mainly Steam game backups and some ISO's, along with a number of files that are already zipped. I am assuming the drive compression isn't any better than that employed by Steam or Zip. But maybe get some benefit from the ISO's?

 

ISOs don't compress very well either as they are already a selectively/partially compressed format.

You might gain 2 or 3 %, not much at all.

 

Thanks. I figured that. Didn't want to go through compressing several hundred GB only to find out that I saved 1GB. LOL.

 

I compressed about 10DVD worth of stuff using magic iso's UIF file. I seem to get about 50-60% compression ratio. Meaning 10GB files comes 5-6GB file size. I can mount the .UIF as virtual drive as well so you don't have any real limitations or inconveniences.

 

Thanks, I'll have to give that a try. Does Daemon Tools recognize UIF?

 

nope. But why not use magicdisc. It recongnize .uif file + everything that daemon tools can.

 

Because Daemon Tools is free? Plus I am not too keen on using a format that is tied to only a single program. It would be nice if at least other programs could read the UIF format. But I may give it a shot and see what kind of compression I get. May be worth it to save 30-40GB.

 

So is magicdisc. I think you got it the other way around. Daemon tools cost money and magic disc doesn't. Daemon tools lite is the only free version that company is offering. Also, powerISO can also read .uif format.

 

Thanks. I guess I use Daemon Tools mainly for mounting virtual drives and other software for ripping depending on its content. I just used MagicDisc (MagicISO) for a few ISO's using best compression and it saved only ~5% disk space. I guess I'll just have to manage it some other way.

 

Magic disc (virtual drive program) is free. The Magic Disk maker (ISO creation) costs money.
