James, I was going to ignore this post but I was concerned that this misinformation would be to the detriment of Stephen who asked the original question, so I posted the text on Steve Gibson's Spinrite users newsgroup and received 3 replies yesterday, all of which were illuminating and I can do no better than just copying them here, whether you respond or not is immaterial to me: First response: >From http://www.grc.com/srfeatures.htm "Direct Hardware Interaction with Hard Disk Drives and Controllers: Unlike any other disk utility, SpinRite interfaces directly to the hard disk system's hardware, rather than working through the system's operating system or BIOS. This allows SpinRite to immediately determine the location of any surface defect after a single incident of error, rather than requiring multiple reoccurrences. SpinRite's hardware-level interconnection also allows it to interface with the various functional extensions of the IDE/CAM/ATA drive standards - including LBA mode drives - and to manage the extended ECC error correction available in modern devices. SpinRite selectively disables and enables a drive's read caching, write caching, read-ahead buffering, on-the-fly sector relocation, on-the-fly error correction, dynamic servo thermal re-equalization, early and late ECC error correction, and other advanced features in modern drives. No other disk utility has ever done any of this, even though it results in tremendous data recovery and drive maintenance benefits." >From http://www.kickstartnews.com/reviews/utilities/spinrite_v6.html "SpinRite 6 interacts directly with magnetic storage media at a level below any installed operating system. This version is able to operate on all Windows XP NTFS formats in addition to all DOS FAT, all Linux file systems, Novell, Macintosh (if temporarily moved into a PC) or anything else. SpinRite can also be used to repair and recover the hard drive from a TiVo personal video recorder. SpinRite originally introduced the concept of non-destructive low-level reformatting and sector interleave optimization all of which basically means that the software can read, analyze, correct then rewrite every tiny bit of data on a hard drive, re-establishing the formatting, without losing any original data, without screwing up your files (they'll work better actually) or messing up your partitions (they'll work better too), or fouling up the factory low-level formatting of any hard drive" >From http://www.grc.com/sr/faq.htm "Can SpinRite low-level format my IDE, EIDE, or SCSI drive? No software of any sort can truly low-level format today's modern drives. The ability to low-level format hard drives was lost back in the early 1990's when disc surfaces began incorporating factory written "embedded servo data". If you have a very old drive that can truly be low-level reformatted, SpinRite v5.0 will do that for you (which all v6.0 owners are welcome to download and run anytime). But this is only possible on very old non-servo based MFM and RLL drives with capacities up to a few hundred megabytes." "I thought newer drives didn't need SpinRite? Not at all. We sell many copies of SpinRite every single day to the many people who are having serious trouble with their modern drives. SpinRite is every bit as necessary today as it ever was — maybe even more so since people store so much valuable personal "media" data on today's massive drives. The problem is economics: Drive manufacturers only make hard drives that are "reliable enough" to work "most of the time". It's just like with Microsoft and Windows. Windows is good enough that we put up with the annoyances when it breaks. SpinRite is here to be your tool to pull today's modern drives back from the brink when they are beginning to misbehave." HTH, Matias
