Hard Disk Problem and SMART Value Questions

I've seen a thread:
http://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.

Thanks for the link,but there I still has some question

Thanks for the link. It was also posted in Melina thread, but I still has some question unanswered.

1.Some people said that faulty cable/Motherboard could cause damage to the HD. How this is possible?

Maybe that is the cause that my other HD that was previously fine now get lower "Raw Read Error Rate" on SMART Value every time I shut down or restarted my PC. I just change my other HD that previously also has Bad Blocks two days ago with a new HD. Both of them (the one which has Bad Blocks and my other HD that now has lower SMART Value)was used same IDE Cable. So I'm thinking the cable is faulty even though maybe the HD itself is failing.

But,I don't want to hear people say like "You've got a fever so you must have got a influenza".What I mean is don't just said "the HD now failing because it SMART Values strangely lowered so replace it now". I think a doctor make diagnostics first before telling what is the sickness people has.

2.Why after my Friend installed new SATA Drive, he always got slower startup on Windows? His other HDs is IDE HD/ATA ->This his first SATA HD. This question still remain unanswered.

3.The SATA HD doesn't appear as Master and Slave on both Primary and Secondary. Is this normal?

4a.Why some people said that their External HD gets Bad Blocks after not used for some time? I understand if it already has Bad Blocks in the last usage, but they said the Bad Blocks appear out of nowhere.Don't answer this question with answer like "They unlucky","Something unexpected happened sometimes". Everything that happened in this world always had a cause so I want to know what could caused it.
b.What caused Bad Blocks in CD/DVD?
These two still remained unanswered.

Sorry if my post offends people here.
By the way, thanks for reading my questions and answering them even it not the answers that I really want.

Your questions, answered one at a time.......

by ThumbsUp2 In reply to Thanks for the link,but t ...

I'll answer your questions, to the best of my ability, one at a time below (in bold).

1.Some people said that faulty cable/Motherboard could cause damage to the HD. How this is possible? Electricity spikes

Maybe that is the cause that my other HD that was previously fine now get lower "Raw Read Error Rate" on SMART Value every time I shut down or restarted my PC. I just change my other HD that previously also has Bad Blocks two days ago with a new HD. Both of them (the one which has Bad Blocks and my other HD that now has lower SMART Value)was used same IDE Cable. So I'm thinking the cable is faulty even though maybe the HD itself is failing. Perhaps the controler on the motherboard is defective due to POWER SPIKES

But,I don't want to hear people say like "You've got a fever so you must have got a influenza".What I mean is don't just said "the HD now failing because it SMART Values strangely lowered so replace it now". I think a doctor make diagnostics first before telling what is the sickness people has. And, your point is? We've diagnosed the problem and told you the disease that it has is terminal. But, you don't want to hear that, do you?

2.Why after my Friend installed new SATA Drive, he always got slower startup on Windows? His other HDs is IDE HD/ATA ->This his first SATA HD. This question still remain unanswered. Not enough power to run the SATA drive

3.The SATA HD doesn't appear as Master and Slave on both Primary and Secondary. Is this normal? Yes, SATA drives are not configured primary/slave. They are numbered.

4a.Why some people said that their External HD gets Bad Blocks after not used for some time? I understand if it already has Bad Blocks in the last usage, but they said the Bad Blocks appear out of nowhere.Don't answer this question with answer like "They unlucky","Something unexpected happened sometimes". Everything that happened in this world always had a cause so I want to know what could caused it.
b.What caused Bad Blocks in CD/DVD?
These two still remained unanswered.
Power spikes. All it takes is one spike or fall while it is spinning to damage the drive. Also, static in your body while you're handling the drive, before it has been installed back into the computer, can damage it.

Sorry if my post offends people here.
By the way, thanks for reading my questions and answering them even it not the answers that I really want.
Your posts don't offend us. We're just getting tired of trying to give you a FULL COLLEGE DEGREE PROGRAM ON ELECTRONICS through this forum. What you're asking us to do is not possible. If you want to know more about how electronics work, get yourself enrolled in a degree program. AND, by the way, your last statement says it all. You don't want to hear what it is we have to tell you.

Thanks for your answer and sorry about my questions

by keven_alberto_yoesup In reply to Your questions, answered ...

Thanks for your answer about this... I'm really sorry if you feel like that you are lecturing me about electronics.

1.Some people said that faulty cable/Motherboard could cause damage to the HD. How this is possible? Electricity spikes

Maybe that is the cause that my other HD that was previously fine now get lower "Raw Read Error Rate" on SMART Value every time I shut down or restarted my PC. I just change my other HD that previously also has Bad Blocks two days ago with a new HD.

Perhaps the controler on the motherboard is defective due to POWER SPIKES.


You may be right about this, but I used a stabilizer to power up my PC and this problem suddenly happened after I installed a new SATA HD two days ago. And the weird thing the change in SMART Value happen after startup, maybe the new SATA HD stressing my other HD on Startup. Some more info in number 2.

2.Why after my Friend installed new SATA Drive, he always got slower startup on Windows? His other HDs is IDE HD/ATA ->This his first SATA HD. This question still remain unanswered. Not enough power to run the SATA drive

He just change his power supply and I'm also getting this problem too -> Slow Windows Startup.Both he and me used SCSI/RAID Controller and VIA SATA RAID Controller.
Someone also said it was driver issues. Is this true?

Once again, I'm really sorry about this. This happened when I and my friend have had so much assignments (about Database and Information System, not about Hardware) in my College now.
