New second hdd disappears after every reboot, appears after rescan
Hi
Firstly my specs are
Windows 7 Home Premium 64bit
Intel Core 2 Quad Q8300 @ 2.5GHz
Foxconn G31MX motherboard
4 GB installed memory
The current hdd is a WDC WD7500AADS
The hdd i'm trying to add as an additional drive and having trouble with is WDC WD40EZRX
I have just installed a new Western Digital 4TB green internal sata hard drive on my windows 7 PC
The drive is always visible in BIOS but whenever I start the Windows the new hard drive doesn’t show up in explorer or Disk Management. It will be visible in both after either scan for hardware changes in device manager or rescan in diskpart but when windows restarts I have to do this again for the drive to be visible. If I leave any data on the drive then once I have rescanned for the drive all the data is visible and intact.
Apparently this bug or similar issues are common in windows 7 but none of the potential solutions that have worked for other people have worked for me.
Other people seem to have a problem where the drive letter needs to be reassigned after reboot but for me once I have rescanned for the drive the drive letter I have previously assigned to drive persists and doesn’t need to be reassigned. I don’t know whether there is any relationship between these issues.
I’ve tried changing the sata port on the motherboard.
In diskpart hidden is set to no as is no default drive letter. I have tried setting volume to hidden and then changing back to not hidden.
I have tried a selection of drive letters.
I’ve tried formatting the drive again in windows.
I’ve tried Error checking the drive in windows and no problem was found.
I read that this might be a solution (http://support.microsoft.com/kb/978980) but it hasn’t worked.
I have automount enabled.
I tried starting the computer in safe mode and the drive shows up. I then tried starting the computer with all non windows services turned off and the drive did not show up.
I've tried completely uninstalling my antivirus(AVG) and it didn't help.
I read in a couple of places that several people had had success solving this issue using a Western Digital utility to write zeros to start and end of the volume. I’ve tried this and it didn’t work for me. Also although people who had tried it claimed that their data was inexplicably still intact on the drive my drive was erased and needed to be formatted after I tried this.
I have been into explorer>Organize>folder and search options>view> and unchecked hide empty drives in the computer folder.
I ran Microsoft Fix It and it said hardware changes might not have been detected, scanned for hardware changes, the drive appeared and it marked as fixed but the drive disappeared again after reboot
I tried making it a new volume and formatting on another computer and then moving it back to my computer but this hasn’t worked. I had read that some people had fixed the problem by formatting the drive on an xp machine and then moving the drive back to their windows 7 machine. I don’t have access to an xp machine but I used another 7 machine. Incidentally the drive showed up immediately and as expected when I plugged it into the other windows 7 computer.
I've spent over a week trying to find a solution to this and I can't find any more suggestions so I'd be extremely grateful if anyone could suggest a solution.
Thanks for reading
Ben
