Hi, I have an unusal problem with a USB hard drive.
The drive is around 200 GB and formatted as ext3.
It was fine until I had to access it with a windows box, I installed software from here
Ext2 IFS For Windows
and it worked very well indeed. However, since then any data transfers done from or to my linux machine only go at around under 1MB per sec, whereas previously around 18 20 MB sec was the normal rate.
Since then it has been formatted as NTFS and was fine with the Windows (vista box), now however I want to continue using it with Linux, so I formatted it as ext3 again, using the partioner in YAST but the problem still exists.
I can only get under 1 MB per sec using linux pc writing to the drive and reading from the drive.Any ideas?
Many thanks, regards Peter.
I have a similar problem with my USB-SATA drives.
I have one ext3 and one ntfs hard-drive and both show the same problem on Opensuse 11.1 64bit KDE4.1
All copy-processes start quite fast at above 40MB/s but then drop rapidly below 20MB and finally after a few 100MB it goes even below 10MB/s and only if I change some process-priorities for kio_files it remains “up” there near 8-10MB/s, otherwise it very likely ends up at 1-2MB/s
I used Kubuntu 9.04 32bit KDE4.2 before and although Kubuntu had issues with the load during copies it remained above 25MB/s
