  1. The program "ForceTrim" creates a file across the free space (as known by the operating system) and then deletes it. It expects Windows 7 to then send a trim for all sectors belonging to this file. This works if Windows 7 normally does it for your drive (with a different driver than you have now in XP). You could run it after a significant number of files have been changed, once a month or so. I've tested it by writing some data onto an empty sector with WinHex, and it disappeared after a few seconds.
  2. Can a program stop Windows from writing to the disk while it is working? What if it finds free space, then the system puts some files there, and a moment later a trim is sent to delete the new files. Usually various low level disk utilities require the disk to be unmounted to work. On Win7 when trim is working, deleted files immediately appear as 00 00 and cannot be recovered. Maybe you could install NT6 in dual boot, and occcasionally run ForceTrim from there.
  3. People seem to vote for controversial claims, sometimes very expressively laid out with ranting, to which they agree. On modern forums where the thread itself gets voted for, I feel discourage to make a post because the opinion of the crowd is difficult to predict. It is a social suicide to make an unpopular claim, even if it is articulated calmly. I usually don't bother to open a heavy website to press the like button. Sometimes I do it to acknowledge that I've read what the other person had to say, but don't have anything further to add.
  4. Access the the USB disk with a hex editor like WinHex and see if you can interpret its contents. If so, then you can image it and recover the files.
  5. GTX 750 Ti is a decent entry level video adapter for a general purpose PC when you're looking for playing "legacy" games only or watching videos in h.264 format. It is quiet with very low idle power consumption, which is important these days, and requires at most one 6-pin 12V plug. It does not have a h.265 decoder, for which you'd need Maxwell 2, but those are much more power hungry. One more thing to keep in mind that 9xx were the last cards with a VGA port. Anything described as a "gaming" computer usually requires the latest stuff of the day. I think you will able to run basic 6-8 year old games with zero anti-aliasing in HD with a GTX 750.
  6. Many Internet forums now operate the extremely heavy, new generation "Discourse" engine. Old browsers including New Moon receive a read-only compatibility version, which is completely unusable. It may be "clean and modern" and completely crippled. The page extends below the screen, and there is no apparent way to scroll it at all. Disabling JavaScript doesn't do it. I just found out that appending ?_escaped_fragment_ (or &_escaped_fragment_ ) to the URL makes the page scrollable normally. It's perplexing why Discourse doesn't work like this by default. For example, https://boards.straightdope.com/t/how-are-people-feeling-about-discourse/926428?_escaped_fragment_
  7. It was simpler than I expected. There is a 32-bit identifier at 01B8h in sector 0. After the new disk was mounted by Windows for creating the third partition, a new ID was generated for it. The solution was to write the old ID there and reboot without making more changes to the disk. To make the edit to the boot sector persist, I used Bootice. I was also mistaken about BCD editing not working outside Windows 7. I confused it with UEFI. It does work, but was not needed. All drive letters remain the same.
  8. I cloned with WinHex by selecting sectors from 0 to the end of the second partition. But it's a simple direct copy, so other tools could do the same. Having the OS partitions of minimal size makes this part easy. I want to replace a 128GB SSD with 512GB to have more space for programs and games, but now got demotivated.
  9. I've cloned my system disk to a larger drive. The new drive won't boot. Apparently I need to convince the OS that the drive partitions are the same. The cloned volumes are exact same size with same serial numbers. I recall I need to go into the registry and edit DosDevices. What complicates the setup is that I have Windows 2008 R2 with its new complicated BCD bootloader. I'm posting here because the problem is mainly with NT6 that I know little about. I can only edit the BCD while having booted into Windows 7 (not from a boot CD) with BOOTICE, and it refers to different drive letters of the current system. I do not want to edit the present system with Microsoft tools, but the cloned one. The new disk is currently connected to a secondary SATA controller. I don't know if it matters to how the BCD sees it. • Partition 0 4GB: BCD boot loader, Windows 2003 SP2; C: for NT5, B: for NT6 • Partition 1 24GB: Windows 2008 R2; C: for NT6, B: for NT5 Neither of these would boot with a message from the BCD boot loader. The NT5 is never loaded. What steps do I need to perform to complete the clone?
  10. Yes, I can boot off the older Data Traveller 2GB.
  11. I found a Kingston Data Traveller 2.0 2GB. It works and shows up in the list of connected hard disks. I doubt that the size is the key issue here because I previously used a hard disk in an enclosure to boot Windows and special programs with this computer at work. I suspect the difference might be that the new USB stick is USB 3.0 (which it doesn't need to be) and the old is not. I did update the BIOS before I changed the CPU. Booting previously worked with stock BIOS. Those numbers 6.00PG don't change with updating. Pentium 4 computers always have 6.00 and Pentium II have 4.50 or 4.51.
  12. The motherboard is GA-965G-DS3. In the F12 boot menu it shows the same categories that can be selected in setup: Floppy, Hard Disk, USB-HDD, CDROM. It does not list specific disks. Choosing USB-HDD from the boot menu still doesn't work. The USB stick is 16GB. I will have to find another that is smaller later. The BIOS looks like this, except missing are the USB-HDD0:... entries in that menu. https://www.youtube.com/watch?v=29qV5xXh09A Normally I don't mind waiting extra 20s on boot, but when troubleshooting I need to go through the Intel AHCI screen again and again. Disks also lose staggered spinup, because they get powered on immeidately on the Energy Star screen.
  13. What do I need to do to boot from a USB drive on Award BIOS v6.00PG? The computer is from around 2007. I've little experience with booting from USB. In boot device options I have USB-ZIP, USB-FDD, USB-HDD. Tried Legacy USB Storage Detect: Enabled; tried disabling AHCI and Native mode. The USB stick does not appear in the list of Hard Disk Boot Priority, as I've seen on other instructions. Only SCSI HDD are there and an item called Bootable Add-in Cards (tried that). I made the Kingston Data Traveller 111 with Universal USB Installer and SARDU. It contains one FAT32 partition, syslinux and GRLDR. Perhaps this is too complex, but ultimately I need this to be useful instead of something like a DOS diskette. The system didn't show any signs of reading from the USB. PS. The Intel AHCI BIOS has an annoying massive delay while it waits for hard disks to become ready.
  14. I see it in View->Settings. By default they are sized to logarithmic scale. The partition is completely invisible to the Disk Manager. I feel like it's a waste. It would be cool if that space could be loaded with DOS utilities, which can't access any other NTFS disk, but it seems to serve no purpose at all. Is 4TB "small" already?
  15. I had two ST 250 GB PATA drives fail after a few years, with either weak heads or debris inside. They are only slightly older model than the 320 G. Clearly anecdotal experience with one doesn't apply to the other. New drives since 2012 or so have a built in function to park their heads after a short period of idle time. This normally only happens when power is removed. The drive might accumulate tens of thosuands of head parking cycles during normal use (S.m.a.r.t C1). This could be disabled by changing the advanced power management (APM) value using a procedure that applies a DCO and inadvertently also saves the APM value. On the most recent models this doesn't work. One must use Seagate OpenSeaChest utility (requires NT 6.1 or making Linux boot disk). I am still puzzled by he hours counter. Would be good to hear if anyone has it at greater than 66,000.
