Discussion Overview

The discussion revolves around concerns related to hard drive health, specifically regarding the presence of reallocated sectors and the implications for data integrity and potential drive failure. Participants explore the effects of usage patterns, such as keeping the computer in sleep mode versus shutting it down, and the reliability of external hard drives without SMART technology. The conversation touches on data backup strategies and methods for addressing bad sectors.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants express concern about the implications of having 11 reallocated sectors, noting that hard drives are statistically more likely to fail after the first event.
  • There is a suggestion that keeping a computer in sleep mode does not necessarily harm the hard drive, but opinions vary on the best practices for hard drive usage.
  • One participant mentions that bad sectors can be discovered during the Power-On Self-Test (POST) if SMART is enabled in the BIOS, while others suggest that bad sectors may lead to system crashes if the operating system attempts to access them.
  • Backup strategies are emphasized, with participants recommending regular data backups and considering the purchase of a replacement drive.
  • There is mention of using software like SpinRite to repair bad sectors, although the effectiveness of such tools is not universally agreed upon.
  • One participant shares a method for fixing bad sectors using the command prompt and the chkdsk utility, indicating that this process can be time-consuming.

Areas of Agreement / Disagreement

Participants generally agree on the importance of backing up data and the potential risks associated with bad sectors. However, there are multiple competing views regarding the best practices for hard drive maintenance and the implications of reallocated sectors, leaving the discussion unresolved.

Contextual Notes

Limitations include varying definitions of hard drive health, differing opinions on the impact of sleep mode, and the effectiveness of various software tools for addressing bad sectors. The discussion also reflects uncertainty about the consequences of encountering bad sectors during normal operation.

So my computer is just over 1 year old. I put it on sleep a lot rather than shutting it down (but I don't think this hurts the hard drive). Is there any reason for worry? According to HD Sentinel, the percent health is 88%. According to "Failure Trends in a Large Disk Drive Population", my hard drive (14 months old) has a ~90% probability of making it through the next 8 months (after the first reallocation).

There is a concern though, after the 1st event, hard drives are 15 times more likely to fail in the next 60 days or so. I did get most of my items backed up but not all of them yet. But none of my two external HDs (one lacie, one western digital) have any SMART technology enabled on them so I can't check their progress at all.

Also, bad sectors are only discovered on bootup, right? What if you just left your PC on all the time? Would the computer suddenly crash upon coming across a bad sector or what?

Not necessarily. It's more of a power save feature than anything else.

Bad sectors can be discovered in POST, if you have SMART enabled in BIOS. Usually after 1 bad sector it won't be long until that spreads to affect other sectors on the platters. Most times it's a run away effect. Backup your data and start shopping for a replacement.

I always recommend having a 2nd storage drive connected to your machine whether internally or externally. Usually heat can lead to a head crash on a HDD, or cause the platters to become slightly warped. How's the airflow on your system?

spinrite is a nice program that helps repair bad sectors...

If your OS tries to write something important to the bad sector, or if it has already written something there that it needs, it will definitely crash. Happened to me not that long ago. The computer will 'freeze up' and then you get the blue screen of death upon rebooting.

Back your data up regularly!

Fixing all bad sectors

When I worked for roaminggear.,com, that one discount computer site we basically see that all the time. You just have to boot into a new command prompt windows in the laptop or whatever your working with. Thats CMD in the RUN menu. Type chkdsk /r and then type y for running on bootup. It takes a while so make sure you can live without it for a while. If its really bad than you never know.
levtechllc, used, new buy its all a matter of what's best for you. Check out deals somewhere and see.
