Hard drive drastically dropped speed, and increased latency!

post #1 of 17
Thread Starter 
My 640GB Hdd ( WB caviar Black) is now having problems . Its really slow . Cant watch movies , its lagging , write sped is 3-5MB , and read speed is 4-5Mb . All My data is on it . I use a 2x500GB Raid0 for os/games , and its working fine .

What could be the problem ? I defragement it weekly , and check for errors too(it does not have any errors) .

Should i try to copy all my data to my Raid0 , and re format it / or RMA ?

Don't defrag it weekly, you would wear it out faster, defrag 2-3 months :thumb

How full is the drive? How old? have you checked the S.M.A.R.T data?

Google is your friend.

http://en.wikipedia.org/wiki/S.M.A.R.T.

Quote:
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; sometimes written as SMART) is a monitoring system for computer hard disk drives to detect and report on various indicators of reliability, in the hope of anticipating failures.

When a failure is anticipated by S.M.A.R.T., the user may choose to replace the drive to avoid unexpected outage and data loss. The manufacturer may be able to use the S.M.A.R.T. data to discover where faults lie and prevent them from recurring in future drive designs.

GSmartControl will fully access your SMART data and give it to you (doesn't work on Raid drives, nor does any other program i'm aware of )
post #6 of 17
HDTune / HDTune Pro can also show you the SMART info, under the "Health" tab.

Take a screenshot and upload it here.

If I had to guess, bad or loose SATA cable. Try replacing it, or plugging it back in tighter/straighter, or even try flipping ports.

Yeah. Defragmenting can improve performance a little bit if it's heavily fragmented but its nothing worthy of a weekly defrag. Not worth the added wear on the drive.

Okay . Its weird now . I could copy all my data from the drive ( really slowly) . Reformated it ( full format ) , And SMART does not shows any issues now ? What the ? Was this just some corrupted file system ?

Is it bad, or just was corrupted ?
