I have the same problem on multiple drives, multiple systems. The only thing that changes is the offset. On a 3 Terabyte drive attached to an internal interface with GUID partition table (model WDC WD3001FAEX- 00MJRA0 (01.01L01)) I get: Error seeking to offset 30005927936 (g-io- error-quark, 13).
On a USB 2.0 connected Hitachi 82.3 GB drive with no partition (model TOSHIBA THNSNH128GBST (HTRAN101)) The R/W benchmark actually started but then I got: Error seeking to offset 2470412288 (g-io-error-quark, 13). This is interesting as the drive label indicates the total sectors are 160836480. Disconnected and reconnected this drive and then got: Measuring transfer rate (0.0% complete)… and it hung. 3rd attempt on this drive duplicated first results. We appear to be seeking beyond extents. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1081019 Title: Benchmark for Harddisk fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/1081019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
