Surely, that figure is WAY low??? I'd expect atleast about 10MB/s on ATA100. dmsg detects everything right obviously, atapci0: port 0xd800-0xd80f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 0.1 on pci0 ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 ... ad0: 114473MB [232581/16/63] at ata0-master UDMA100 Anything I can look at to speed this up? It's not the most powerfull system ever, P3 850 with 1GB Ram... But I *definately* expect allot more than 2MB/s for 100% load... Thanks, Regards, Chris.
