Anyone know of a good NT disk "checker"

[Cable God]

I am having to fight with my DBA all day long. He's insisting the disk that the db resides on is causing problems. I seriously doubt it. Anyone know of a utility that will read thru the disk and tell me if there are bad sectors or anything that would cauyse an Oracle I/O error? I used db_verify to validate the .ora db data files and they are fine. We movied the db back to the disk and everything's working. I need this for future battles. Thanks guys.

open up My Computer, right click on the HDD< and select properties, then go to tool, and then error checking, then select Scan for and attempt to recover bad sectors.

You may need to reboot and doa boot time scan if the system is activiely using that disk.

We used to use Disk Keeper.

I knew Disk Keeper was a good defragger, but it also checks and scans for bad sectors?

 

[Tauren]

I can't remember right now, but go to Download.com and look for the demo, it should tell you there.

chkdsk

I *ahem* aquired Disk Keeper 6.0 a few weeks ago and will look at it. Thanks for the help guys.

cable, what exactly are you? an nt admin?

1. you're running an oracle database on a box without raid?

if so you are crazy.

force a chkdsk on the partition and reboot the box.

See #1 otherwise.

 

[tim0thy]

it might be a database on a test network... doesn't mean that it's mission critical or anything...

 

[Cable God]

it is just a QA Testing server. tim0thy, I am Director of IT at a medium sized financial services software development company, but I am more of the-go to for everything guy when it comes to problems. Yes, we are a brick and mortar company, not a dot com. By the way, it runs on a dual PIII 866, 1gb of Rambus PC800, 2-36gb U160 SCSI IBM's, no raid, just one heck of a tape backup sys, 2-Exabyte Mammoth2 60/120's with an autoloader for each.

 

[tim0thy]

i would definitely suggest raid 10, but if you got a good backup strategy in place, run with it! if it is in a QA environment, there might not be enough updates to justify raid anyhow.

auto tape loaders... schweet!

i think i need to start a thread on system administration. i've been doing desktop work for about 2 years and armed with an MCSE+I, i think i'm ready. but what's the best way to go into system administration. what kind of questions are asked?

check the eventvwr on your box, under system, for any disk io problems, they are ALWAYS logged in nt/2k/xp .

You also should check for any eventvwr app errors related to oracle.

It's highly unlikely a scsi drive has bad sectors, if so, its about to blow hard, and your event log would show..
