So, which is the culprit here? I guess whichever it is, it's in version 132 as well. As an aside, double negatives always annoy me because they can so easily cause confusion. Having a flag which has to be enabled to disable something for instance!

Thank you, that has fixed it! So, what does that mean?

Interesting. Maybe I should report this to the developer on GitHub, especially if the problem is still there in version 132. I've just tried the 64 bit version on Windows 10 on another computer, and it's the same, although that's not surprising as that installation of Supermium is set up the same way. I'm quite sure that if it mis-renders this site, it will inevitably do the same on others, although I've not come across any (yet). Strange that some have said that it's working properly for them though, with the same version of Supermium on the same operating system.

Thanks everyone, as always! A lot of food for thought there. Some more information that I should have given the first time. I'm using Supermium 126.0.6478.260 R6. Off-topic here of course, but I'm using the 64 bit version on Windows 10, and the British Gas site looks exactly the same there, so it's presumably not an OS issue. I'm not using a loader on Windows 10, but I am using Chrome+ which gives me the additional function of always opening bookmarks in new tabs, something that I had got used to having in 360Chrome. Unfortunately Chrome+ does not work on XP, or I would be using it there as well! This is my version information page on Windows 10 - A lot more 'out of the box' than the XP installation of course, as most of the tweaks needed on XP are not needed on 10. This is really quite puzzling, as I'm using a recent Chromium version here. It will be interesting to see if the problem is still there in Supermium 132 when I get around to updating to it.

Thanks, so it is something in my setup then! My chrome://version page looks very different to yours. For instance, how come yours says 'Supermium' at the top right and mine says 'Chromium'? Is that perhaps because I'm on XP and not Vista as you are? I don't see why that would make any difference. You can see the flags and switches in the screen grab, do any of them stand out as possible culprits to the problem? I am using a launcher program to run the browser, with some switches in its INI file, such as the profile location.

Could someone who's using Supermium 126 check this site for me? https://www.britishgas.co.uk This is how it looks in Firefox 135 (and Edge) - This is how it looks in Supermium - As you can see, the elements above and immediately below the red bar are missing on Supermium, which apart from anything else means that you can't log in. Also, some other pages on the site are just showing as white pages in Supermium, and the same pages look fine in Firefox and Edge. Notice the big difference in the uBlock Origin count numbers on the two browsers. This is probably relevant, but disabling uBlock does not solve the problem! It's the same in an incognito window in Supermium too.

I think that sort of thing is getting pretty par for the course now with 360Chrome, because of its old Chromium version (86). Spoofing the UA string only has limited use now, as many sites use other methods to determine what level of browser you're using.

Thanks.

He hasn't posted here since last summer, although he is still a member. You could try sending a PM, but it would be much better to ask about your issue on the Supermium GitHub pages.

I haven't seen anything like that happen so far, thank goodness. So you're saying that just going into the Disk Management on XP causes the partition on your 6TB disk to vanish? Does it not appear at all, or does it appear and then disappear? Presumably it's gone in Device Manager too?

Thanks, but it's exactly the same on Windows 10, where I'm not using the Paragon driver of course. I was thinking that it was due to the fact that it's an IDE controller connection, not a mass storage device connection. I can't remember whether it was the same when the disk was connected directly to the motherboard. Incidentally @Cixert my card is actually made by a company called SSU. There is very little about the card on their site, but is does look as if they only make the SU-SA3004 four port version, not the SU-SA3002 two port version. There's a driver download page, but not much else!

That post did indeed refer to Windows 2000, but this isn't the thread for any prolonged discussion about Windows 2000 issues. If you post in the relevant Windows 2000 thread, you can always tag people in this thread to bring it to their attention.

@Xeno96 Post moved here. This thread is concerning Windows XP only.

If you edit the first post in the thread, you should be able to change the thread title there.

OK, back again. I did my phone backup, and system ISO backups yesterday onto the 3TB disk, and everything still seems to be OK. I'm still getting the message about 'making corrections to the uppercase file' when I run CHKDSK on Windows XP, but this does not seem to be anything serious. I did some research on it, and this was stated about the 'uppercase file' - "Windows changed the uppercase file -- that's the one that provides translation between uppercase and lowercase, to preserve case-insensitivity for path names -- a little bit, between XP and Vista. You get this error if you formatted the drive under Vista or later, and are running CHKDSK under XP or earlier." So, it looks like it's just a difference between the way that XP records case information and Windows 10 records case information, nothing to worry about. So, no file system corruption problems as yet, and the drive does have more than 2TB of data on it. There seemed to be two key things here. Firstly, finding the right version of the Paragon GPT driver to use on XP, for which thank you @Cixert. Secondly, finding a SATA interface card which would work with the disk without causing corruption, for which thank you @Andalu. The card I'm now using, which is this one, appears as an IDE controller, not a SCSI storage device, and that seems to have been the key, because it presumably is exactly the same as connecting the disk directly to the motherboard, which also works. The seller's information on Amazon describes the 'no boot' mode on the card as 'data disk', which is exactly right in my case. Whether this would work with a disk that you wanted to boot from I don't know, but for my usage it's fine. The card I have is actually a version 1 card, not the version 2 card I posted the image of. The Amazon seller says you could get either version, but the only difference that I can see is in the PCI-E interface version, which doesn't seem to matter. The card is apparently branded 'Mugast' which is not a name I'm familiar with. The only thing I've lost is the automatic detection and mounting of the drive when it's powered up in its enclosure, which is not a big deal. I think this is probably because of the way that the operating systems now see its connection. I'm just glad that it works! I will of course report immediately if I do find any issues after prolonged use. Cheers, Dave.

Fixed.

It starts pretty quickly on my machine, but my hardware may be more powerful. The only issue I've seen is that when I back up a disk to an image file, there is a bit of a delay in it actually starting the operation, and in the Windows System log there's a string of information entries which say "Timed out sending notification of target device change to window of DiskGenius". The number of entries varies, and they seem to mainly be when the operation is initiated, but the operation does still complete successfully. I did query this with the developers, and their answer was "Windows XP system is too old, which may have caused this warning message due to its lack of certain features." I suppose that's fair comment! It is indeed a great program, it amazes me just how much the free version can do. Cheers, Dave.

I'm using DiskGenius 5.6.1.1580 on XP and it works fine. It is however one of those programs that won't install on XP, you have to use the portable version.

@Andalu @Cixert I think I've got things sorted out now. I uninstalled and reinstalled the Asmedia card on XP, and this time the driver installed correctly, so there's no more 'new hardware found' pop-ups. I'm not sure what went wrong the first time, but the extra 'IDE Controller' entry in Device Manager is no longer there, just the extra Primary and Secondary IDE Channel entries. It still seems to work fine. It even works in Windows 98, and I can now use my 2TB MBR disk in Windows 98 with the Paragon NTFS driver, which I could never do before as none of my other cards have Windows 98 drivers! Windows 98 doesn't see the 3TB disk of course as it's GPT. The only slight outstanding niggle is that the disks are not now recognised and mounted automatically when they are connected, either in XP or 10, but I can live with that. The Hotswap! program that I use to safely dismount the disks has a right click menu option to scan for new hardware, so I can just use that to manually mount the disks. The big test on the 3TB GPT disk will come later today when I do my monthly backup of my mobile phone onto it. That involves many thousands of files written very quickly, so if that doesn't trigger the corruption, nothing will! I can only do that now in Windows 10, as the backup software no longer supports XP, but I will be scanning the disk with CHKDSK in XP straight afterwards, with my fingers crossed. I will report back! Cheers, Dave.

Thanks @Andalu, that's amazing research! Off-topic again, but I've now configured the card as an IDE controller on Windows 10 as well by changing the driver, and it's all working great. So, the only thing that's not good now is having to dismiss an add hardware window every time I boot XP. If I do anything else with it, the system just freezes permanently, What's mainly puzzling me is why it's being found as another IDE controller, when it's already installed as one, and I can't see that anything's missing!

I realise that this is getting off-topic, as it relates to hardware, but I think what's happening with my card is that there is an extra device being detected, which is actually the on-board chip, which pretends to be a 100MB disk, called 'ASMT109x- Config'. This is the XP Device Manager without the card - And this is Device Manager with the card - So it looks as if the card is adding one extra IDE Controller, with associated extra Primary and Secondary IDE Channels. As each channel supports two devices, that would be the four SATA ports on the card. If I run the card in 'No boot' or IDE mode, there is no BIOS text on boot, but if I run it in AHCI mode, I see this - That shows the 'phantom' disk, labelled 'ASMT109x- Config'. Research indicates that many people have been puzzled by this! In fact (even further off-topic) in Windows 10 that 'disk' actually appears as an uninitialised disk in Disk Management! I found the only way to stop it popping up messages about it was to declare the disk off-line. So, it would appear that this 'phantom disk' is also the 'code 10' device shown in the Windows 98 Device Manager, and also the cause of the system freezes in Windows XP, which is trying to load a driver for it! All I've got to do now is somehow to stop Windows XP seeing it! Any ideas anyone? Anyway, to get back onto topic, things look good with the 3TB disk with this configuration. If works fine, and I've written to it using Windows XP and Windows 10, and there is no sign of any corruption apart from when I check in Windows XP after being in Windows 10, CHKDSK says it's "correcting errors in the uppercase file". I have no idea whether this is anything to worry about or not, but it's certainly nothing like the huge list of index corruption errors I was getting before!

@Andalu Yes, it is strange, but my system is very far from being 'standard'! Interestingly, Windows 98SE sees the card as well in the 'no boot' mode, and also tries to install it as an IDE controller. Again it tries to install two of them, but in the case of Windows 98SE, the system does not freeze. In The 98 Device Manager, one of the two controllers appears correctly, but the other one has a yellow mark saying it can't start (code 10). Windows 98 does not see the 3TB disk of course, presumably because it's GPT. I will try later on with a smaller MBR disk! So, what I suspect is happening is that the card is being seen as two controllers (probably because it has 4 SATA posts on it) and in Windows XP it's installing one of them, but then freezing when it tries to install the second one. As I said, I really only wanted the 2 port version of the card, but I couldn't find one anywhere. You don't happen to know of a source? I suspect that the 2 port version wouldn't cause the issue.

@Andalu OK, back again! I now have this card. I tried to find the two port version, but no luck anywhere, so I had to get a four port one. As said, in the 'no boot' mode, it appears in XP as an IDE controller. The only problem is that it keeps on trying to install another IDE controller, and when the driver is being installed, the system just freezes permanently. This happens even in Safe Mode. Any idea why that would be @Andalu, and did you find the same problem? In Windows 10 it appears as a normal storage controller, exactly the same as all the other cards I've got. The good news is that it works fine on both systems with my 3TB disk fine, and going between XP and 10 no longer seems to result in any file system errors on the drive. This is how it's seen by Disk Genius in XP. Of course, it's much too early to say whether it will be reliable in actual use, but it's looking quite hopeful! It does have more than 2TB of data on it. Cheers, Dave.

The card I ordered arrived, and it turned out exactly the same as the ones I tried before! It's still an Asmedia 106x chipset card of course. D'oh! I've now ordered this one, which has the magic mode switch. I'll let you all know how that goes!

Our posts crossed! That's the same driver file I used with the Asmedia 106x cards I tried. The 3TB GPT disk was recognised OK, even without the Windows 2003 files, everything looked normal, but the filesystem kept getting corrupted.
