The internal hard drive in my 4 year old Aspire Z5610 cooked itself this weekend. I could not match the drive exactly so I put in a new 1TB hard drive. Of course, the old recovery partition was cooked along with the user partition and this drive does not have the Acer recovery partition. I used the 3 recovery disks and these seemed to work to a point. But when the system configures the services for the first time, an error pops up saying the installation cannot be completed on this machine and to start again. Well, I started again and again and again. Same error. I found a hack to get me past that and although it leaves me with a Windows 7 I can log into, lots of things don't work. In particular, the Windows update service will not turn on; this is a major problem. I cannot turn on indexing. Also eRecovery doesn't recognise the DVD drive (the internal one stoped working a while ago so I use an external USB drive that in all other respect works perfectly). The Acer system information detects the machine perfectly with the serial number and SNID. I would be astonished if the Windows 7 OEM build has been designed to only work with one type of harddrive - which is the same manufacturer just a slightly larger capacity. So I can only think there is something else not quite right but I haven't spotted it yet.
Any ideas?
