I want to reinstall Windows to a blank SDD drive
I have a 128G SSD drive. It was installed before I was aware of the
bios setting AHCI. When I try to enable AHCI I get an error. Now I have bought another 256G SSD drive. I guess to enable AHCI I will have to reformat and I am OK with that. When I run Win7 setup what can I expect to see? Do I have to reformat the drive? I understand that I wont' keep my old data, but I want to be sure there are no relic folders and I have a clean new system. |

Search for Windows 7 change to ahci may work KenW Thanks. I really don't like changing registry entries, but since that is easier than having to re install. I will give it a go. One other thing I was reading is that you need drivers for SSD. I don't think I ever installed a driver and if I did, I am not sure I still have the driver disk. Is it true that I should be using drivers? |

One other thing I was reading is that you need drivers for SSD. I don't think I ever installed a driver and if I did, I am not sure I still have the driver disk. Is it true that I should be using drivers? An ssd is just another drive as far as Windows 7 is concerned. I never heard that other drivers are needed. In fact, a few years ago I cloned a hdd to an ssd with Win 7. This laptop with an ssd uses the same drivers from 2006. You may want to watch this thread in case someone thinks I have it wrong. I believe a clean install will take care of all the weird things an ssd needs. KenW You might need a driver for NVMe. That could be an M.2 drive (PCI Express x4 on horizontal screw-mount installation). Or such drives can be purchased as a PCI Express plugin card (same shape as a video card housing). For the others, the OS has AHCI and IDE drivers. And a "driver re-arm" using the registry can be done, so that the OS "re-discovers" where the hard drive is at boot time. You generally want to set the re-arm registry entries on enough entries, to cover both cases. Maybe re-arm MSAHCI and MSIDE or something, so that if you screw up on the next boot and don't alter the storage setting in the BIOS in time, the system will come right back up. Re-arm varies slightly from one OS version to another - I look that up when I need it. Both the AHCI and the IDE driver may have TRIM, so you might not need to change from one to the other. In an Administrator Command Prompt you could check. What this one does, is check that the OS is set to send TRIM commands, not that the driver level actually has TRIM https://www.howtogeek.com/257196/how...it-if-it-isnt/ fsutil behavior query DisableDeleteNotify -- DisableDeleteNotify = 0 # TRIM is enabled -- DisableDeleteNotify = 1 # TRIM is disabled OS ---- disableDeleteNotify? ---- Driver TRIM passthru? --- drive_gets_TRIMMED There are also some programs (like SSD toolkits) that can functionally check that TRIM is actually working under test conditions. There are a number of tools (i.e. some amateur programming projects) for actually verifying it is working. TRIM helps the drive keep track of which clusters are re-usable. The drive would work without it, but there would be less slack space for optimization and packing when the drive is idle. The drive should have megabyte alignment for partitions, as flash blocks are on power_of_two boundaries, whereas the virtual geometry of MSDOS partitioned drives is at multiples of 63 (bad for Flash). The Windows 7 installer DVD makes this choice without your help. I did have a case where I got a bit too clever, and formatted something in WinXP before installing Win7, and the drive actually ended up mis-aligned. And then I had great fun fixing it. I used Macrium Reflect Free, and it has a dialog for setting the alignment on a restore. Generally, you have nothing to worry about, if you just booted the Win7 DVD while a brand new drive is present and let Win7 make the choices instead of forcing them like I was. You can use Macrium to clone from one SSD to another if you want. A re-install can correct a lot of sins, but you also have the option of fixing everything the hard way. During a Macrium Reflect Free clone, you can re-align to megabyte boundaries if you want. Some drives don't even have TRIM, and have their own internal heuristics for keeping track. And some SSD toolkits have a "re-trim" operation, to do a bulk passing of info about the file system(s) to the SSD. You can apparently blast the drive with a ton of TRIM commands, but it can be a struggle for the drive to keep up. ******* Regarding the "clean install will take care of all the weird things", you'd want to set the BIOS SATA port setting to the desired value (like AHCI if you want), just before booting the Win7 installer DVD, as then when selecting a driver it's going to have the AHCI one as the final choice. In effect, the OS installation has all the drivers re-armed, before the first functional boot. Once a driver choice is made by the bootup process, the re-arm bits are adjusted so that no time is wasted on subsequent boots, choosing a driver. If you want to change modes, then you have to manually fix the Registry settings to make it possible on the next boot. Paul |
