WD’s Data LifeGuard sometimes has problems communicating with drives in a Windows environment. The bootable CD version should work fine, though.
BTW, I notice that DLG is reporting IDE mode for your drive instead of the usual SATA. Is this because you selected IDE compatibility or legacy mode instead of AHCI in your BIOS setup?
Your drive’s SMART report looks good apart from the extremely high UDMA CRC Error Rate. This makes me wonder whether your drive’s performance has been reduced from DMA mode to PIO mode. You can verify this in Device Manager. You can also see this in a HD Tune read benchmark, for example (the graph will be a flat line). A high raw value for this attribute normally suggests interface or cabling problems.
As for the Power On Hours Count, your drive appears to have been operating for 16275 hours (= 0x3F93). That’s nearly 2 years, and judging by the Power Cycle Count (0x77 = 119 decimal), it would appear that your drives run 24/7. I see nothing wrong there.
