PC-3000 Forum

Hy everybody
I got an external WD5000LMVW-11VEDS0 drive with 2060-771949-000 REV P1 pcb, from usb pc3k cannot identify it. I swapped the pcb with 2060-771959-000 REV A. It can earn ready state (about 20 sec), autodetect OK and come up in normal mode. After that I recognise the drive switch of it's SA acces on HEAD 1. On copy 0 all modul are OK. I recovered head 0 fully without any error while reading,but head i couldn't read anything. It isn't trying read just show each sector bad. I switch head from a same drive, with good head 1 and weak head 0. After that it also earn ready and comes up in normal mode but head 1 still didn't read. I swap head again from a WD5000LPVX-75V0TT0 ( I find a description on forum, it can be good donor) each 2 head is good! Now the drive also earn ready state, comes up normal mode,isn't any audible sound, has SA acces in each head,. I saved all modul and track from head 1 and the modules are also good but the drive still don't read any sector on HEAD 1. I trying regenerate rom and write it to the drive but it isn't solve the problem so I write back the original,I tried slow responding but still no succes. In sector editor Head 1 give UNC error. Head0 still reading good.

In DE head 1 isn't trying read sectors just show all of them as BAD

I will be very gratefull if anyone can give me advice or any procedur which can help me.

protontech, did you check the donor heads if they able to read by head 1 in donor drive?

Hy Maxim
Yes I check the heads with head test and with DE also, each head read good!

No, I mean, if you install the donor heads back in donor and read by head 1, will it read?

It can read, I test it. And now I checked the donor HDD also can read with the original head 1. I think the problem is maybe in rom because first the HDD come up with only head0 SA acces and i think it is deactivate the head1, i see remove head option but not show any deactivated head,and it isn't try read just show every sector as bad. There isn't 9 small squer int the top right corner where usualy show the reading trys. It just step sectors and show all of them as bad.
