Hello,
I have a Dell Latitude 3550 with WD10JPVX HDD. Since last month there are some serious problems with Windows 7 and I'm not completely sure if it's an HHD problem or maybe with other hardware.
Windows 7 sometimes is working, sometimes not. For example, there were no problems for a week, and then BSOD appeared with information "kernel data inpage error", after reboot everything was ok. At the next day there was an information at boot saying "no system found", after few restarts a new information was displayed with BOOTMGR to repair the boot sector (I didn't do anything, just turn off the laptop), after two hours I tried once again to turn it on and Windows 7 was loaded without any problems and it was working ~5days, and after 5 days the same scenario took place.
Every time when were problems with loading the OS I run the Dell Diagnostic and each test said that HDD is OK, however, when I tried to clone the disk I received the info that some of the sectors cannot be read, but at third attempt disk was cloned without any information about bad sectors. I replaced the disk two days ago and everything seems to be working. I run the surface test using "Victoria" software and there were no errors at all, SMART also looks ok.
Any ideas what else can cause this problem?
