I am currently in the process of replacing an HDD in a friend's computer in which the drive, a 40 GB Maxtor Diamond Max Plus 8 series model # 6E040L0, that failed in under 2 years of use. This is of some concern to me since I have an identical master drive and, based on what I have been reading online, Maxtor drives have recently slipped in both performance and reliability. Anyway, that is neither here or there in regards to my question, just a factoid that I feel people should be aware of before considering a Maxtor drive. Anyway here goes: after considerable research at a variety of websites and overwhelmingly positive reviews on Newegg's [Once you know, you Newegg ] website, I settled on a Western Digital Caviar SE WD800JB 80 GB replacement drive. My question is this: Since Maxtor's PowerMax drive utility is rebranded DrDos, I can use it to error test, burn in, and certify the drive, right? This is the drive utility I am familiar with and wish to use. Once the drive is determined not to have any problems, I will partition and format it NTFS, using Partition Magic. Western Digital may have a utility similar to PowerMax, but I'm not familiar with Western Digital's drive software. Is WD's Data Lifeguard a drive overlay or a utility that runs in Windows? I had not planned on using a drive overlay, since it is not needed for a (relatively) small 80GB HDD on a recent MoBo.
