Why won't W7 detect HDD partitions automatically on startup

October 28, 2012 at 14:05:02
Specs: Windows 64
I have a WIN7 64-bit based system with a single internal (DISK 0) Seagate ST31000528AS hard drive.
The 1 TB hard drive has 4 partitions: a Boot partition and 3 other various storage partitions.
Recently, upon booting the 3 storage partitions are not recognized. Initially, I feared the data might be lost as windows disk management utility identified the corresponding space as "unallocated".
Low and behold, the simple action of "Rescan disks" in the action menu immediately detects the partitions as configured; the drive is restored. All data is available.
Now, every time I reboot I must go to the disk management utility and "rescan" for the partitions to be detected.
How can I fix this? Why are they not detected upon booting? Please advise.

Not a good sign, it usually means the drive controller is faulty so the drive needs replacing. I would test it with Seagate SeaTools for DOS which runs from a bootable CD so that Windows isn't running while the test is carried out. Download SeaTools for DOS ISO file from here: http://www.seagate.com/support/down...

Then install IMGBurn from here: http://www.filehippo.com/download_i... and use it to create a CD from the SeaTools ISO file.

Then boot your system from that CD & SeaTools will open. Run the long/extended test on the drive.

Phil22, thank you for the reply...I had feared it was a sign that the drive was going. I did run the seagate WINDOWS tools. This did not report any errors.

However, when I tried to run the DOS tools the drive was not recognized!? The drive is recognized in the BIOS.

I ran a second windows based error checker (HD Tune Pro) and when i cam back in the room the system had rebotted and hung at the boot screen.

Any additional thoughts? I am all backed up (of course) at this point and I have my finger on the "buy" button for a new HDD...

See the link below. You may need to update the drive firmware.

Not necessarily accurate. You should never test the system hard drive with a Windows -based diagnostic tool as it means you are then running the test software on the very same drive you are testing!

That's why you must only use testing software which runs from a bootable CD.

Windows-based testing software is for testing a non-system internal storage drive or an external hard drive which DOS-based software can't detect unless you install DOS USB drivers.

That series drive and the 7200.11 are both prone to premature failure. You can RMA the drive but you will most likely receive a refurbished unit that will not last very long.

I suggest you go to WD blue or black series drives. Green are OK for storage but are slow for an OS.
