Dear all, This is my 1st post. You may already know what's my problem (Post title says it all ) So, the power failure happened while I'm running chkdsk on the questioned hdd in my winxp (p4) pc. It has 3 hdds (80gbx2 & 160gbx1). Both 80gbs are doing fine. Problem (extremely slow. some files read rate 300kbps) occurred on the 160gb drive. Already done everything to fix it, without any luck. 1. Reset the partition table & create new ones with different sizes. 2. Change the sata port, changed sata cable/power cable. 3. Plug in to a different pc. 4. Tried fat32 & ntfs file formats. 5. Google search with relevant keywords. See the attached screen shot. (hd tune read rate) Read speed is fluctuating like crazy. Is this happened to anyone before ? Any ideas ?? Any cure/fix ? Thanks & best regards. Nayana Sri.
