SCSC Releases Free eBook: Hard Drive Troubleshooting

in Tips and How To

[prMac.com] Reston, Virginia - Software an Computer Systems Company, LLC, (SCSC) has just released a new, free eBook in PDF format title "Hard Drive Troubleshooting." The book, which is 141 pages in length is available for free download to any interested users from SCSC's web site

"This book is provided to complement our hard drive scanning and analysis tool, Scannerz for Mac OS X," stated an SCSC spokesman. "If someone thinks they have a hard drive problem, we thought it would be a good idea to release a book explaining how they can test and evaluate their problems without possibly buying an unneeded hard drive, or for that matter, software. Although the book references our product, Scannerz for Mac OS X, the fact is Scannerz, or for that matter any other analysis tool on the market cannot and will not be able to identify a problem that appears to be a drive problem, when in fact it may be traced to something else, like a failing power supply. This book traces the data flow all the way from the I/O controller on the logic board to the read and write heads actually exchanging data with the drive platters. We hope this book will become the de facto standard reference manual for hard drive and system problems on Mac OS X based systems."

"Through years of analysis and experience, we've determined that hard drive related problems can range from the obvious to the obscure. Examples of obvious failures would include a logic board with a bad I/O controller or CPU, a failed controller on a hard drive, or a severe head crash rendering a drive useless. Obscure problems, which are every bit as, if not more common as obvious problems, can include such things as cracks in traces on the logic board, a weak solder joint, or connectors that are marginally functional. Obscure problems typically yield extremely erratic system performance, often with intermittent errors, leading users to believe they have a severe, unrepairable problem, when in fact it it might be easily fixed. The purpose of this document is to provide owners with a set of procedures that will allow them to at least understand what's going wrong, and in many cases, fix it."

Topics covered by the book include the following:
* Definitions of failure and problem types
* Descriptions of how particular failures and problems effect systems
* Identification of problems and failures on internal and external drive systems
* Software problems that can appear as drive or system problems
* Remapping bad sectors to good sectors on a drive with platter damage
* Dealing with drives that aren't visible to a system
* Dealing with drives or systems behaving erratically
* Dealing with drives or systems suffering from intermittent lockup or shutdown
* Dealing with drives or systems suffering periodic crashes

The book is intended for users using systems that typically fall into the following categories:
* They're using systems running Mac OS X Version 10.5 (Leopard) or higher
* Either a PowerPC G4 or Intel based system

Although the book is clearly targeted at users using Apple Macintosh based systems, the general theory is applicable to almost any Mac or PC based system. SCSC invites anyone interested to download the book from their website.
