I have a Seagate SDR00F1 1TB external hard drive. It was brand new I took it out of the box yesterday.


Yesterday, I copied a bunch of movies and TV episodes to it, and today I tried compressing the drive.


However, compressing the drive is taking forever! It has already been five hours and it is only a fourth of the way complete!



I have compressed 2 TB hard drives in the past faster than what this 1 TB drive is compressing. There is only 400 GB of data on this drive!


I Googled 'external hard drive taking forever to compress' and 'compressing hard drive slow' but only results about people asking if compressing hard drives slows down your system showed up! There is literally zero results pertaining to compressing hard drives taking a long time or slow.


I need this to finish as it is typing up my only open USB port. All the other USB ports have permanent things attached to them.



Does anybody know what the problem could be?

Hope it s 3.0 or 3.1 USB Port. Also, it could be File System connected. Finally, make sure your unit allows NTFS compression.

I said that it was 1 TB. That cannot be anything other than NTFS. FAT can only go up to 128 GB and has problems over 40GB



Now Windows is telling me "3 Days remaining"


Compressing 400 GB of data SHOULD NOT take three days

If you have it connected to a USB 2.0 port, it will max out at around 30MBps. With USB 3.0, sustained copy speed should get close to 120MBps for writing and almost 130MBps for reading.


Also keep in mind that it is a slow 5,400 RPM low-powered device.

There's also the option, if you only have USB 2.0 available, of compressing in a folder on the computer, first, then copying over the compressed result.

NOT TRUE!!! The original drive that these files were on were compressed, it removed the compression upon moving these files onto this drive. So no, it DOES NOT copy the compressed result over! :(

Then set the drive itself as a compressed drive BEFORE you try to move anything to it.

And, by the way, I was thinking compression by ZIPping rather than using Windows drive/file compression in my original reply.

There's never enough space savings for me to use Windows compression.

You should have enabled compression on the drive first, then copy the files. It might even be faster to cancel the compression, format the volume, enable compression then copy the files again.
