CRC errors after defragmentation?

[imported_Xylo]

I built a computer a couple of months back with a new Maxtor 250Gb MaxLine III HD. Over time, I filled up about half of the drive, and recently realized I hadn't defragmented it since installation. (I was also having some problem with a little bit of spyware.) I cleaned up the drive, removed any spyware using Spybot and Adaware, deleted a bunch of unused stuff, and decided to defrag it. (BTW, this is all in Windows XP.)

After defragmentation the computer has been running REAL real slow (much MUCH slower than it was before). I checked processes and what not, and all the spyware is gone, and nothing is taking up a bunch of CPU time or some other oddity. It would just appear that sometimes the machine will pretty much "hang" for 20-30 seconds somewhat randomly, but fairly often (once a minute or so). Twice, I've gotten CRC (cyclical redundancy check) errors.

I'm currently running chkdsk on the drive, and I'm not yet sure if it's stuck at 22% or just taking a real long time (at 250Gb, it should reasonably take a number of hours, so it may just be slow). Aside from possibly defrag having moved data to bad sectors on the disk, can anyone think of what else may be causing these sorts of problems?? Any help would be greatly appreciated.

Thanks...

Ok, it definitely frozen on the physical disk check at 22% (left it there for over an hour, no go)...I've rebooted, but not sure what to do next. Try an alternative disk checking tool??

You can try the manufacturer supplied disk check tools (check the maxtor website) those can most of the time offer more info about where it failed and why.

I'm afraid your disk is toast however, so I reccomend you try and get the most important data backupped ASAP.

You need to keep trying to run the chkdsk. But if you want to, try running Maxtor's Utility program. This will tell you if the hdd has surface problem or even allocation table problem. The other option is to back up your data and then reformat and re-install. Personally, I would back up data on a separate hdd or cd and then reformat and re-install. When you decide to do this, recommend partitioning the hdd into two partitions and use the first partition for all programs and os while the second one for data. So in the future if you need to re-install you do not need to back up your data first before re-installing. Of course, it's always a good practice to back data on a separate medium.
