Yesterday I got a new 4TB WD hard drive - put it in my Win7 system, Initialized as a GPT Disk and formatted. All's well. Spent hours copying 3TB of data onto it from other drives (it's serving as a backup for me). This morning (after some overnight copying) it looked fine, I clicked through some of the files and directories, and then shut down to connect a different drive to continue filling it.
After restart - the new drive comes up listed as Local Disk and OS alerts me it needs to be initialized before use. I shut down, swap it to a different SAtA cable (from another drive), same thing. Move it to a 2nd SATA controller on the bus, same thing.
Wierd and worrisome thing is that this exact same thing happened with the WD 3TB drive I was using for this backup - that's why I replaced it, and a Seagate 3TB drive that was also being used. So this machine, for some reason, is now formatting drives and letting me copy onto them, restarting mutiple times, and then a day or two later the drives are blank again.
One other strangeness - twice in this process with the Seagate and WD 3T, i ran full reformats in Disk Management, that somehow ended with the drives being formatted as 860MB (not 3T as both were). Also very strange.
It 'feels' like something corrupt at the OS level - but no idea what it would be. I don't think these drives are bad. I guess it could be I've got a bad SATA cable in the bunch. Generally though I'm super confused - and need to get my backups done onto one of these drives.
Ideas greatly appreciated.
