Windows 7: A swap back to 32 bit disables the DVD drive

A swap back to 32 bit disables the DVD drive

Hi Guys.

I have been running happily with an All in One Medion desk top,
which I have modified slightly. It is really a notebook chip based system, only two sata outputs, but it does have a touchscreen and digital tuner. It is a 2.3Ghz Pentium dual core.
4 GB mem and 1.5 TB over two drives.

I pulled the DVD drive out of sata 2 port and fitted it in an external housing on a USB port. Then I wired the sata 2 port out via an eSata socket to a sata HDD docking station.

I have been running six months with two versions of Win 7 Home premium 64bit in dual boot mode with no probs.

Last week I decided to replace the 64 bit with a 32 bit version so as to run some older programs.

So I formatted the external 1TB drive and loaded win 7 32x from the original disks. Took while with all the updates and SP1.

While doing this, I had no problem with the DVD drive but, as soon as I was up and running, the DVD drive stopped reading disks. Swap boot back into Win7 64 bit and it is fine, boot from win7 32 bit and it is a dodo. It recognises the drive ID but will not open a file or boot from a bootable disk.

I have checked for out of date or missing drivers but nothing shows.

I suspect I have a protocol problem, Not sure. It appears to be using a new Win7 sp1 driver. Or maybe something wrong in Global settings.

Any advice appreciated.

Many thanks Theog but,

Microsoft's Mr Fixit is as mystified as I am.

Nothing detected.

I might try borrowing a mates dvd drive for a comparison test

My system appears to have cured itself?

Now working fine except for auto run, but it will respond to a mouse double click and load a program or open files.

I suspect that the cheap chinese external housing with the USB to sata adapter sitting in the back of the DVD drive may be giving an erratic contact on maybe just one pin.


Anyway, I do have Mr Fixit esconced on my system, if further problems arise.

Thank you Theog.
