I’ve seen a thread:
https://www.techrepublic.com.com/5208-6230-0.html?forumID=101&threadID=265144&messageID=2512253
My friend also has similar problem as her (Melina). So I want to help him by asking in this site.
It is easy to said that he just have to replace his HD. But I want to ask some question first to make him feel safe. Now he’s paranoid because this was the First Bad Blocks problem that he has and my other friends seems also never has Bad Blocks problem on their HD. I’m also worried if this could suddenly happened to me.
1.Some questions about SMART Value:
a.Some people said that if Bad Blocks remapped then RAW Value of Reallocated Sector Count increased (not 0 anymore).
However, in my friend HD the Bad Blocks not remapped but stays as “Current Pending Sector” and “Offline Uncorrectable” because both of them has same RAW Value (186) so I think the Bad Blocks not remapped/or cannot be remapped.
Could someone tell me why the Bad Blocks doesn’t automatically remapped by the HD or the OS?
b.What is the meaning of Attribute 187 (Reported Uncorrectable Error) and Attribute 189 (High Fly Writes)? Sometimes they list as Unknown attribute 187 and 189.
My friends HD RAW Value of 187 is 1443 (Reported Uncorrectable Error) and RAW Value of 189 is 2(High Fly Writes).
What is the cause of them?
c.Before he know his HD has Bad Blocks -> The HD which has Bad Blocks is not where Windows installed, Windows always has slow startup and Windows always do CHKDSK at startup. Is this normal? However, the progress of CHKDSK is really slow, he said he estimate it could take about 14 hours to finish the CHKDSK so he always skip it. Is this normal too? His HD is about 160GB Seagate.
d.Then he used CHKDSK /r in his HD (it also took about 14 hours like the CHKDSK at startup), it removes the annoying CHKDSK at startup, but Windows still has slow startup.
What caused this?
e.He assume that the Bad Blocks mostly in Free Space of his HD, because when he add files to it, it worked fine but when he try to move the same file to another HD it gave him CRC Error meaning the file was placed in the Bad Blocks.
What caused the Bad Blocks appear in the Free Space of HD and why did Windows still placed the file in the Bad Blocks even though my friends already used CHKDSK /r?
2.About the Hard Disk problem, in question number 1 I write that my Friends HD has a Bad Blocks.
a.How could I know a HD is failing or not other than Event Viewer (Showing Paging Error or HD has Bad Blocks),SMART Test, or I heard Clicking sounds?
SMART Test sometimes doesn’t help like in my Friend case and I don’t want to check Event Viewer and doing SMART Test and HD Test everyday.
b.My friends has made a backup to an External HD, but he still worried about it because some people said that after some use the External HD doesn’t get detected by the OS(Windows).
What caused it? And Why sometimes people said Their External HD get Bad Blocks after it hasn’t been used for a while (months/years) even though it was placed in Cool place (not Overheat), rarely moved(doesn’t had any vibration), and in a clean place. What caused the Bad Blocks in the External HD that sometimes appeared even though it is not been used for some time?
c.My other friend also has another problem after he add a new Seagate SATA HD to his PC, this is the first SATA HD that he has. The SATA HD shows as SCSI HD in Device Manager and SeaTools (so he couldn’t test the HD using SeaTools). He also has slower Windows startups after the new HD installed. He used Windows XP SP2.
What caused it and what should he do?
d.Why sometimes people saying they had Bad Blocks in their CD/DVD? What caused it?
e.Does a sudden power outage harm a HD? What should I do if it happened?
Edit: I also have same problem as question 2c, but I wonder this is related about my other problem, deleting folder when I seeing folders in Zip Files using Right Click->Compressed (Zipped) Folders is really slow. My File System is NTFS, I’m also using Window XP SP2.
Sorry if someone think most of these questions have been answered in thread started by Melina.
Thanks for reading and answering.
