This is my situation:
I recently changed the HDD in my MacBook Pro (Mid 2010) to a Samsung 1TB HN-M101MBB, and I installed Snow Leopard on it since i'm not too happy with Lion.
A couple of days later I found the computer to crash when running Google Chrome. It got progressively worse, I wasn't able to even start Chrome without the entire system would freeze and force me to do a hard reset. I installed Firefox, it also failed in a similar way, next was Iron (Chromium based browser). It too worked fine for a day then froze up my computer. Lately it takes forever to just boot the computer and it feels like running OS X on an Amiga 500.
The OS X Disk utility is more or less useless, reports SMART ok and no problems what so ever when running the tests like scan/verify/repair.
When I'm running "Scan and Repair Bad Sectors" -> "Scan volume for bad sectors" in Speedtools Utilities Pro 3.7 I get a message "Scan sector failed", no matter if I run it on the disk mounted or unmounted. When I'm doing benchmarking on it with "test data transfer integrity" in Speedtools I get reasonable scores, avg 200MB/s or so. When running a 5 minute test on the drive when mounted and as the system drive I get more or less 0. Maybe a couple of megs a second if I'm lucky.
It feels like the whole system is waiting for something all the time, but it doesn't use up a lot of cpu or memory. Almost like there are semaphores locking each other out or something (ah you get the point, was a couple of years a go I read those things in school). Something wrong with the HDD, some SATA interface problems with the new drive or what's up? I really don't want to re-install everything again to discover that it will happen another time and I can't send the drive back based on it might be some issues with it.
Oh, I also ran the antivirus ClamXav, got a couple of "LibClamAV Error: fmap_readpage: pread error: Input/output error" errors, if that helps any.
