I have many hdd with problem that has driven me nuts the problem is that the hdd is identtified correctly by its name 6e040l0 and its full of bad sectors from start to the end and when i check modules many modules are bad when i try to rewrite them it give error in uba i chk SA structure error in datacopy 1 i rewrite datacopy 1 gives error what to do ?

thanks in advance .

If the drive is identified correctly(6e040lo) there shouldn't be any problems in UBA. Maybe it's a side effect of crappy chinese knock-off?
As for the bad sectors in user area you can handle them with Data Extractor, DDI or other imaging software.

no i dont need the data i need to repair hdd as i have many peices with the same problem the one thing i dont understand is that why am i unable to write the SA , the only problem i see here is that there are badsectors in SA is there any way to remove them .
