Title says it all, I was playing Kane& Lynch 2 yesterday and it always hung up when loading chapter 3. I checked the eventlog and found a few event 7 (disk error) entries: The device, \Device\Harddisk1\DR1, has a bad block. This was the first and so far only incident recorded in eventlog. I ran a full chkdsk at boot and it identified 3 bad clusters, 12kb worth of bad sectors:

The HDD is a Samsung Spinpoint 1TB SATA 7200rpm and only 4 months old. I use it for file storage and installed games.
The obvious question - is it fine now that the blocks have been corrected, or is the HDD failing soon - are the bad blocks gonna spread like a virus? Time to get a new HDD and make backups now?

Yea I'm sure the bill is somewhere, if I find it I can replace the HDD for free.

still..I'd like to know that:

@ Shocktrooper: might be a one-time thing, but you never know. I'm personally still a WD fan, as not a single WD drive has ever failed me - my 5 year old Caviar is still doing its job perfectly. I've been fucking around with my bro's HDD today, which he bought just under a year ago. Hitachi Deskstar, supposedly also good drives. Damn thing is completely dead now. Same thing with an external drive I've had, was a 1TB drive achieved by 2 500GB Spinpoint F1's in RAID-0. 21 months, and one of them completely broke down.

Samsungs drives are good drives. I have the F3 1TB drive and it is fast and reliable. I also have 4 WD's too. I am no fan of anyone's. I just happen to buy products that have the best reviews. I look for specific models - not just makes. Most drives come with a 3-YR warranty. RMA it and get another one.

You can't call a drive that's less than a year old reliable already Smile

bad blocks on hd especially if the number is growing is a bad sign (means all the spare sectors for remapping bad blocks have been used up too) and you should back it up and send it in for raplacement.

If a sector is physically damaged, more will usually follow.

bad sectors were only safe in old drives (in the nineties)
if you have bad sector in a newer drive it's a sign of the apocalypse
maybe not immediate, but from weeks to several months of consistent loss of data (most unnoticeable in normal use) and then one morning total drive failure
i recommend a full backup and RMA immediately on any drive with a single bad block
you might be able to stretch a storage drive with bad blocks to years of low-use with minimal issues beyond slow response time, but i really wouldn't risk it if you're using it for anything but temporary files or porn
if warranty is valid, there's no reason not to send it in immediately
well, apart from disk space, but you could just get a second one.. you'll need it anyway sooner or later Smile

RMA rules aren't that easy though, they'll just send it back to you if there's a few bad sectors that was "fixed" (remapped).

What a great timing. I checked everything with RMA yesterday and they said they're gonna take it back and send me a new one. Then I spent the whole night making 500gb of backups with 10mb/s to another computer in the network. Shortly after I was done, the HDD died silently. Its still showing but I can't access it "the disc structure is corrupted and unreadable".
Chkdsk fails, windows cannot recover master file table. Phew, that was close! Now to remove that fucker and send it back.

It was exactly 20 days from the first registered bad block till HDD death.

Simply put, it's where the hard drive temporarily stores data when you read or write it. It's there to keep disk transfers as smooth as possible, and to avoid the hard drive waiting for the CPU as much as possible. When extracting for example, if you've got a slow CPU that buffer will make sure the CPU always has something to work with. If it didn't have the buffer, and the CPU would take 2 seconds to extract 1 megabyte, the hard drive would have to wait those 2 seconds, find the archive again and then feed the next megabyte to the CPU. With the buffer, it just writes to the buffer until it's full.

In reality it barely matters. Hard drives are much slower than most modern CPUs can process the data. A 32MB buffer is fine, 64 won't really speed things up much.

I'm guessing you're referring to SATA-300 and SATA-600, or more accurately SATA2 and SATA3. The 300 and 600 represent how many megabytes per second it can transfer across your SATA bus. Your motherboard only supports SATA2 (or SATA-300, whatever you want to call it).

SATA3/SATA-600 is not interesting at all yet, as there's barely any drives (not even SSDs) that can take advantage of it.

what utter bulshit ive got a drive that had bad sectors in the first month and the drives still going strong as a porn drive some 3 years later

just use the manufactres tool thing to check the drive if it passes the tests dont worry about it

if your drive is hd103SJ you need to use ES tools to run a diagnostic of the drivehttp://www.samsung.com/global/business/hdd/support/utilities/ES_Tool.html
