Can't format hdd

[Power12]

Hi, I can't format my Seagate IDE hard drive (ST380215A), WB tells it's read only - I've made partitions with HDToolBox, tryied PFS/03, SFS and other file system options, blocksize=512k, maxtransfer=0x1FE00  (and less), I use IDEFix (but can't format partitions less than 4GB too). Disk is OK for MacOS and Win, and cable is OK too so I just don't know what's the matter, maybe it's because too much rpm (I've succefully installed another Seagate drive before, that was old one 1.1GB only), tell any suggestions pls.

I made copy of my old drive with dd, my new HDD boots, but with HDToolBox I can't access disk space over 4GB (size of my old HDD that was source for copy). Though tool determines Seagate's capacity properly (about 74GB) I can't make new partition outside that 4GB area. I tryied to format one of partitions with WB but it still gives write protection fault though I can save and delete files. Yet I learned Format64 can format a partition, but I when it's done I can't access it. And yet I tryed Lock SDH0: off but it doesn't help, so it seems drive isn't locked by software.
