Very slow copy on a Palmer drive

Hi I have a Palmer drive that has very very slow image speed, with many unreadable sectors, But I dont if its weak head or bad surface, or maybe FW issue, is there any suggestion ?
I disable updating mod 190 and try fixing slow in Ram, but nothing changed, still very slow imaging like 8 sector in second!!! I only need 10GB data, but in this way it takes months to be imaged!!!
