My ole system is nigh on 10 years old and beginning to show its age. I switched on last evening to be met with a blue screen and it running a check on drive D: It eventually booted and I ran error check from within windows and then chkdsk and both confirmed I have some unreadable addresses. C: = 250Gig Samsung SSD D: = 1Tb Samsung HDD (partitioned D, E) So fortunately the failing the drive is not the boot drive, it's a 1Tb that is partitioned D, files I don't use much: I have backups) & E: (windows backup/recovery files : Not backed up) So what is the easiest most pain free way to replace it and not screw everything up. No doubt I have a few odds and sods/old apps on D: that I've forgotten about. Is it as easy as remove the old drive and replace it? I'm thinking I may not bother partitioning it and leave it as a 1Tb D: this time. Or is it bite the bullet and clean install? Edit. System booted up this morning without issue.
