[Amarbir[CDR-Labs]]

Hello All,
got This Gernada 2Tb For Recovery Today With Reference From a Computer Dealer In My City Chandigarh .The Client Told Me PCB Is Bad [ Which Was Not True ] . The Drive Would Start And Then Remain Busy .I could Gain Terminal Access And Read SMP Sys File Via Terminal .Removed all checks and Saved and Restarted Drive [ It Was Detected And I Started To Make a Headmap + Mapping Of Needed Files ] . I Do Not Know What Striked Me But i Though The Drive Is Reading Slow So i Should Try Enabling Media Cache In The SMP Sys File .Once i did That The Drive Reverted Back To Old Times Busy With LED :BD Errors .I Am not Able To Gain Access To Terminal Without Read Channel Shorting .I Know How To Identify That But in This PCB There is No Resistor .It Could Be a Pair Near J18 Or Leaving Two Pads From J18 .I Feel i should not try shorting write channel just to identify read channel .Can someone tell me the exact pads .Is this J18 And The Pad Near It Or The Pads After This .
