Why deleting file is so slow?
« on: December 02, 2009, 07:55:48 PM »

It seems the deleting process is not only to add a flag to the file table (common practice in Windows). The larger the file is, the longer it takes. I deleted hundreds of files totally ~500GB. It tooks more than a hour. Is this normal?

This might sound strange - but - were you using Vista?

I also notice similar behavior in slow deletion of files. The larger the file, the longer it takes.

I am on vista x64sp2 and firmware 1.06 final

Thankfully I dont have to delete large amounts of data at a givin time.

I've seen the problem on Vista, but not on XP.

I know larger files take longer to delete, I'm guessing it's something about updating the file directories for the multiple file segments.

Sorry to resurrect this thread, but I didn't see a solution, and I have the same problem from a Windows XP SP3 machine. I'm using the -323 with two 1-TB WD Green drives for external backup storage, and currently the backup files are around 100 MB, one for each of four backed-up drives. Deleting each file takes about an hour, if I remember correctly, which is way too long. Other than the deletion problem, this backup system works well.

The file system on the -323 is EXT2. Would reformatting to EXT3 solve this problem.

Thanks for any help.

Well, that's WAY too long, I've never seen anything like that!
