My WD10EADS-00M2B0 seems to have only 65133 sectors (32MB) total capacity. It was OK for 9 months, and now it reports this false total number of sectors when the OS queries it. I have tested the drive with WDC’s Lifeguard Diagnostic for Windows Software. The SMART and Extended test passed, but the diag tool sees only 32MB of full drive space. Actually, the drive has 32MB cache. But during the extended sector test the heads are moving, so it looks like working. The disks are rotating. Where does the drive store the full usable sector count? Maybe this value is incorrect in the firmware? Could this value be resetted to the original 1,953,525,168 value? Or should I try to replace the PCB with a totally identical drive’s PCB? This should help if the problem is PCB related. Is there any possibility to reflash the firmware? It is strange, that all the SMART parameters are perfect.
The drive is under warranty and WD Customer Service and Support suggests to replace the whole unit, but I need my data to be restored.
