All hard disks will die, sooner or later. They only way to avoid that is to retire a drive early enough. Often I upgrade drives because I run out of disk space, and migrate the data to a bigger drive. However, this times it looks like one of my drives is about to die. <\/p>\n
Over the last couple of months, one of my PCs that is processing data 24\/7 has been seizing up periodically, so I was starting to get suspicious about its hard drives (it has two of them). This week the Windows 7 event viewer reported that NTFS had encountered write errors on the secondary drive. It’s a Samsung SpinPoint F2 EG (Samsung HD154UI, 1.5 TB) which basically has been busy non stop for over three years.<\/p>\n
I installed smartmontools for Windows and it showed errors:<\/p>\n
“Reported_Uncorrect” are fatal errors and “Current_Pending_Sector” are bad sectors the drive wants to replace with spare sectors as soon as it can. Neither is a good sign. So I have ordered a new drive, started a backup to another machine and will replace the drive with a new disk that I have ordered from Amazon.<\/p>\n The new drive is a 2 TB Western Digital WD20EFRX, which is part of WD’s “Red” series. These drives are specifically designed for 24\/7 operation (as opposed for 8\/5 office computers). The drive is 0.5 GB bigger, which is just as well as the old drive was getting close to filling up. Gradually I will be moving my processing to an Ubuntu server, which I already use as my main archive machine with a RAID6 drive array.<\/p>\n","protected":false},"excerpt":{"rendered":" All hard disks will die, sooner or later.
