Hello again, I had a disk problem last week. I started to get disk error messages about disk0, which is I think the hd with winxp on it. My pc froze and I had to restart several times. Later the same day I started to get error messages about disk1 as well, which is my second hd. Also, I was using a trial copy of eset internet security, which started to give error messages too. Then I noticed that one of the svchost processes running was using 20-30% of my processor, which caused my pc to lock down after a while. I didn't know what caused it all, so I wiped c: and did a clean install of winxp and later I did that with the first partition of my second hd as well. Everything went well for a few days. A colleauge of mine gave me a copy of Norton Internet Security which has a 90 days trial period so I installed that one instead of eset. But since yesterday my problems have returned. Disk0 is doing fine now, but disk1 seems to be malfunctioning. The second partition, on which I had a lot of important files, is not accessible anymore, but also the first partition, which I formatted last week and which was almost empty since then is giving error messages in the event viewer. The message I keep getting is that there was an error during a paging operation on disk1. I am very puzzled. How could two disks break down at almost the exact same time? What was going on with svchost? If I had a virus how did it come back after I wiped c: clean and reinstalled windows? I never visit suspicious sites or anything, so except if someone is hacking my pc, it shouldn't be virus related. But if it is my hd's, I don't understand what could cause them both to break down or at least to malfunction. They're both about six months old. I do use them A LOT for image and especially video processing, but still, I have another hd which is two years old and still performs perfectly. I used the western digital hard disk tool and both disks came out fine from the tests. There are no other problems with my system. If anyone could help I would appreciate it alot!
