[this rather belongs to -questions : CC modified] your error messages are most likely due a mis-adaptation between your cable (all the more so if you have a bent pin on one of connectors), the capabilities of your chipset (is it a Via ....) and a perhaps buggy IDE disk (for example, IBM IDE disk drives of the GX60 family are buggy) TfH PS : you may want to post also your dmesg file PS2 : it is possible to downgrade the access speed of the IDE hard disk via the hw.atamodes sysctl in the /boot/loader.conf file (here is my config : dma,---,dma,---,dma,---,---,---, you can replace the keyword "dma" with "pio") Erik Rothwell wrote: > > Hello, > > I've recently added a new 40GB disk to my existing FreeBSD system...
