What You Can Do About It A bad sector on a hard drive is simply a tiny cluster of storage space -- a sector -- of
Detecting Hard Drive Failure
the hard drive that appears to be defective. The sector won't respond to read or write requests. Bad sectors can occur on both traditional magnetic hard drives and modern solid-state drives. There are two types of bad sectors -- one resulting http://www.crucial.com/usa/en/support-system-maintenance-repair-hard-drive-errors from physical damage that can't be repaired, and one resulting from software errors that can be fixed. Types of Bad Sectors There are two types of bad sectors -- often divided into "physical" and "logical" bad sectors or "hard" and "soft" bad sectors. A physical -- or hard -- bad sector is a cluster of storage on the hard drive that's physically damaged. The hard drive's head may have touched that part of the hard drive and damaged it, some dust may have settled http://www.howtogeek.com/173463/bad-sectors-explained-why-hard-drives-get-bad-sectors-and-what-you-can-do-about-it/ on that sector and ruined it, a solid-state drive's flash memory cell may have worn out, or the hard drive may have had other defects or wear issues that caused the sector to become physically damaged. This type of sector cannot be repaired. A logical -- or soft -- bad sector is a cluster of storage on the hard drive that appears to not be working properly. The operating system may have tried to read data on the hard drive from this sector and found that the error-correcting code (ECC) didn't match the contents of the sector, which suggests that something is wrong. These may be marked as bad sectors, but can be repaired by overwriting the drive with zeros -- or, in the old days, performing a low-level format. Windows' Disk Check tool can also repair such bad sectors. Causes of Hard Bad Sectors Your hard drive may have shipped from the factory with bad sectors. Modern manufacturing techniques aren't perfect, and there's a margin or error in everything. That's why solid-state drives often ship with some defective blocks. These are marked as defective and are remapped to some of the solid-state drive's extra memory cells. On a solid-state drive, natural wear will eventually result in sectors becoming bad as they're written to many times, and they'll be remapped to the solid-state drive's extra -- or "overprovisioned" -- memory. When the solid-state drive's extra memory runs out, the drive's capacity will start to drop as sectors become unreadable. O

I cleaned out the fans, and they are running fine, but bios is still posting failed fan, so i unplugged each fan one at a time, and rebooted etc. anyway, i was recommended to clear my cmos, and maybe that will get rid of the error posting. it didn't work, and then when i cleared the cmos, then it wouldn't detect my harddrive anymore. so i took the harddrive out of her pc and error locating placed it into my pc, and ran the western digital data lifeguard diagnostic tool on it, and it had errors, but the tool repaired all of the reported errors. so i thought i was good to go, so i placed her harddrive back into her pc and still the bios wouldn't detect her harddrive anymore. i cleared bios, set default settings in cmos, and still it won't detect harddrive, and i don't know what to do at this point. her pc is a compaq presario SR2173WM with no windows error locating server currently on the drive anymore. system recovery wasn't working either, and her recovery discs can't help when the harddrive isn't being detected. can anyone plz help me? any suggestions are greatly appreciated!! thanks in advance for any input!!

First is to find the place where you configure the hard drive ports. If the hard drive is IDE, go there. But I'm guessing it is SATA, so look at the SATA ports. In each case make sure the port you are trying to use is Enabled. On some BIOS's the default setting (which you restored by resetting the BIOS) may be Disabled. Once they are Enabled, you still have Port Mode to set if you are using a SATA drive. On a machine such as you describe the OS MAY have been installed (almost certain if it is Win XP) using the SATA drive with its port set to IDE (or PATA) Emulation. So close by where you Enable the SATA port, look for a port mode selection and make sure it is set to that Emulation mode. If you are able to see the drive within the BIOS Setup screens, then the BIOS is detecting them OK. To confirm, find the BIOS screen where you set the Boot Priority Sequence. A common choice is to set it to try the optical drive unit first, then the hard drive next, and no other choices. In this screen, most BIOS
