Hi,
I am seeing bad sectors found whe i do chkdsk. I was wondering if anyone can help me discover what is happening because i have already returned one hdd and now think that maybe there was nothing wrong with it.
Is a system unstable when only using one sata drive?
Thanks
Chris

I don't think so. If the number of bad sectors increases over time I believe you're looking at a drive about to fail. I'd keep a simple log for a few days to see where the drive is going.

Thanks SkipCox. I will do. But what are the chances of getting two new hdd's and them both being faulty?

Actually, pretty good...seems occasional production runs from all manufacturers have a lot of bad drives. That's how DeskStar drives get nicknames like deathstar. That said, don't be surprised if a new drive shows some bad sectors. If the sectors show an upward trend, I'd suspect the drive. If the bad sectors just sit there and no increase is noted, I wouldn't worry about it.

I'm sure you are familiar with Maxtor's utilities for checking their drives as you've already RMA'd one. You may also want to contact Maxtor support concerning system stability if you feel the drive is likely ok.

Quite frankly, I've used Maxtor drives for 10 years with few problems and my current 80Gig/8Mb drive is dead quiet and rock solid after a year.

I'll watch this thread for any updates.

Good luck,

Skip

BAD sectors and CHKDSK /R :

Under most circumstances, running CHKDSK with the "/F" and "/R" switches will require the restarting because of open handles on the drive.When the computer restarts, there are no services or drivers running that prevent CHKDSK from checking the disk.

After executing CHKDSK at the prompt, selecting "Y" for yes, will cause CHKDSK to execute the next time windows is rebooted.

How CHKDSK works:

Using CHKDSK with the "/F" and "/R" switches executes 4 major passes over the system hard drive, examining each file record and verifying the consistency of each directory.
If discrepancies or inconsistencies are found, they are noted in CHKDSK’s output.

When an orphaned file is found, it can often be restored to its rightful directory, provided that directory is still around.
If the directory that should hold the file no longer exists, CHKDSK will create a directory in the root directory and place the file there.
We have all seen that FOUND001 etc.

CHKDSK will then take action to repair any file system data.

When the "/R" switch is used, CHKDSK attempts to read every sector on the volume to confirm that the sector is usable. (Note that using the "/R" switch can result in a long
chkdsk pass)


Options for using CHKDSK:

When disk corruption is detected on a volume, Microsoft recommends three basic choices:

Do nothing. For a mission critical server that is expected to be online 24 hours a day, this is often the choice of necessity. The drawback to this option is that relatively minor corruption can lead to major corruption of system and application data. Therefore, this option should only be considered when keeping a system up is more important that the integrity of the data stored on the corrupted volume because all data on the corrupted volume should be considered "at risk" until CHKDSK is run.


Run a full CHKDSK (with "/F" and "/R" switches). This option repairs all file system data, restoring all user data that can be recovered by means of an automated process. The drawback to this option is that a full CHKDSK can require several hours of downtime for a mission critical server at an inopportune time.


Run an abbreviated CHKDSK using some combination of the "/C" and "/I" (NTFS only) switches. This option repairs the kinds of corruption that can "snowball" into bigger problems in much less time than a full CHKDSK would require, but does not repair all the corruption that might exist. A full CHKDSK will still be required at some future time to guarantee that all the data that can be recovered has been recovered.

In conclusion, while the Microsoft CHKDSK utility is not a magical tool for all hard drive and file system problems that you may encounter, it is an important tool in the system administrator’s toolbox for dealing with these kinds of problems. In most cases, CHKDSK will find and correct the problem enabling you to get the sytem back into production in a fairly quick and painless fashion. The critical point is not to delay too long in using this Microsoft utility, thereby placing your windows system data in jeopardy.

Wow SYAR! Did you write that yourself, or did you plagiarize from this site:
