I have a 7737 with the 256 Gb SSD, but I wanted more storage internally and wasn't too fussed about having DVD - so I bought a caddy and replaced the optical drive with a WD Scorpio Black 750 Gb drive.
When I first went into Administrative Tools - Computer Management - Disk Management, it recognised that the drive was there as it told me it needed initialising - so I went ahead and let it. The disk promptly disappeared from the list, and nothing I can do can get it back.
I tried refresh, rescan disk drives, reboot (at which point I can confirm the BIOS recognises the drive correctly, as the 'SATA ODD', but still Windows refuses to acknowledge that it is there. Device Manager only shows the SSD and scanning for hardware changes has no effect.
It could be coincidence, but now my laptop seems a touch sluggish, particularly in the graphics... and I noticed that in the Task Manager, System Interrupts is now taking 10% CPU time on average. I can't say I've ever noticed this before. My old Samsung laptop (which has integrated graphics rather than a dedicated card, to be fair) claims System Interrupts is taking no CPU time at all. This seems to suggest there's a conflict of some sort and maybe that's why the drive isn't recognised?
Since Device Manager doesn't see it, I can't check for updated drivers.
Since Disk Management doesn't see it, I can't format it / partition it / assign a drive letter to it.
The BIOS doesn't seem to let me do anything with the drive, such as go into properties or disable / re-enable it, or anything like that.
Can anyone suggest what I might have missed in the setup, or what I can do to fix this?
Thanks in advance.
