I bought Cyberpunk here last year, and downloaded the 1.63 version for offline backup. Earlier this year I got a new computer, and tried to copy the files over, and with the 4GB sized files, Windows would give an error about a corrupt file system.

I had both the original zipped file that is over 100GB on a thumb drive, as well as the individual files backed up to bluray. I tried it on two different computers (one with 22H2 and the other 24H2), I tried unzipping the large files, same error. Tried copying over the files from bluray and the same error.

Does anyone have any such issue? I also have Mafia Definitive Edition, and Windows has no trouble copying over the large files. I had to install linux to a separate partition, copy the CP files over (and linux never complained), then copy them over to the Windows partition. Windows had no trouble installing (or copying or moving the files) after that.

I can try again so I can post the exact error that Windows says, if you like. But it's ONLY the CP files that I have these issues with. Any ideas?

1. What is the filename of the 1.63 version? Currently GOG offers it only as one big zip file, is it that same or some older download when 1.63 was still the "main version"?

2. Was the Windows error about a corrupt file, or file system? The former suggests the file is corrupt, the latter that your Windows filesystem has some problem, possibly your hard drive is dying or something?

3. Have you tried installing the 1.63 version using the installer's built-in integrity check? It should tell you which file(s) are possibly corrupt.

I can check what that big 1.63 zip file contains, I presume it contains the old multipart installer files, after which I could take md5 or sha256 checksums out of them and you could check if your files match the checksums, but running the built-in integrity check should tell you as well which file(s) are possibly corrupt, and need to be redownloaded. In this case, it means you need to redownload the whole zip-file, in case you don't want to install the newest version available, but the legacy 1.63 version.

Thanks for the reply. For some clarification. The file is cp_163.zip, downloaded after I bought it here. After downloading I tested the zip and it came out normal. I backed that zip up to a thumb drive, then extracted and burned those files to blurays (and verified).

Later I tried to install the game to another computer and it came up with the error - Error 0x80070571: The disk structure is corrupted and unreadable. That was when I tried to extract the zip or copy the files from bluray. I tried on two of my computers, one was a fresh install of Windows. Both computers, both the thumb drive and blurays do that, but only on the files that are 4,194,304 in size (according to Windows). A couple of other files that are smaller copy over just fine.

So after I copied the files to my Windows partition from Linux, the game installed and ran just fine. Once the files were on the hard drive, I could copy them/move them around in Windows without issue. *shrug*

And thanks, I didn't know that Cyberpunk had an integrity checker. Next time I install I will use that. If any files are corrupt, I will just have to repurchase the game (which is no problem).

Since I tossed out the thumb drive, thinking it was bad, it would take far too long to check the integrity of the files from bluray, so no need to bother. Thanks though.

1. So do you have both the big cp_163.zip file, and the installer files extracted from it, burned on the bluray and written to a thumbdrive?

2. What were you doing when that error occurred? The error occurred when trying to copy any files or extract the zip file straight from the external media to your computer?

I googled for that error code and I didn't find a clear indication what might trigger it, other than that the media (bluray or the thumbdrive) is corrupted. Then again it seems you were able to install from those files anyway so maybe Windows just got somehow confused etc. Not sure what is the filesystem you use with the thumbdrive, I presume either exFAT or NTFS.

By the way, I don't think the integrated zip tool in Windows can handle that big zip files, so you have to use some 3rd party software to extract the installer files from cp_163.zip, e.g. 7-zip, WinZip or WinRAR. I hope you meant "redownload". You don't have to repurchase anything just because your local installer may be corrupt.

@timppu;

1. I *had* the zip file, but lost it when I tossed out the thumb drive. Stupid me, I thought it went bad. I had extracted the files after downloading, burned the files to bluray.

2. I have WinRar and 7-zip. I tried to extract the files directly to my hdd from the zip file. After a bit it spit out that error. Thumb drive (and hdd's) formatted as NTFS. I then tried to copy the files directly to hdd from the blurays, same exact error.

I would have to purchase again cause it's not in my library. Last year after purchasing nearly 70 games, I thought I got all the games I wanted, and closed down my account cause I (thought) didn't need it any more. :P I don't mind buying it again if I have to, but I don't think I need to.

Thanks for the thoughts. I think it might be some weird Windows error. Two computers, one with 22H2 and the other 24H2. Same exact error. I don't know. I'm still planning to get an external hdd to copy the files to, and just run the installer from that in the future. It's on my to-do list.

Have a good week!

USB flash-drives i do not recommend for long term storage, and there is absolutely no reason closing down a GOG account. After all, it is not only a useful "cloud storage" which you are missing now, it is as well "proof of purchase".

Actually i only see 2 viable long term archive options plus one "special option": HDD°°, BD and Tape (which is most pricey but surely long lasting). °°Does not matter external or internal, but internal is more reliable because a HDD simply does not enjoy any shock (which may happen at some point, i can tell you) and SATA is more secure than USB. So, a internal HDD should always be the "main HDD" and a external HDD should be "secondary" as a backup of the internal HDD.

As a fast external drive for huge data: M2 SSD in a external enclosure (any other drives are no good deal anymore, simply no good value for what you get).

USB sticks/SD cards just for not to huge portable data (Smartphone, Dashcam and alike), no long term storage. Sorry to inform you but if your stuff is truly corrupt now you have to buy it another time because you lack cloud storage and most likely a "proof of purchase". Simply "how the cookie crumbles", even for those who kinda are living "in another world with lot of magics involved".

And of course if you make long term backup, verify the integrity of your files after... else the best backup-option might be useless.

This is a personal note related to the archiving/data security matter, but might be useful for some users too... because if it is not done correctly it may cause some tears at some point. Sure, this is just the "surface level"... there are very detailed guides on the net for more advanced infos "on how to handle it", including tools.

HDD refresh interval: 3 years (this is a very safe value, at 6+ years it may start to become unsafe). Long term archive possible.

M2 SSD: If regularily (at least once a month for several hours) connected to the PC: No need for refresh. However: Not recommended for long term archive, install data only!

Flash drives without M2 controller or not regularily connected to a PC: Every 1 year. Not recommended for anything except short term portable data (camera, data transfer from/to a smartphone or from/to another PC).
The "charge" of a portable flash drive (non M2) can fade at any date above 1 year... without refreshing it.

Optional for very long term archive: BD-R, Tape. No general endurance known, as it mainly depends on the quality of the medium and the burning/writing procedure... which can vary a lot. 50+ years of longevity is possible with low risks, if done correctly. The true drawback is the high cost and work for huge data and the hard accessibility (need compatible drives, getting rare).

Data refresh = reformat and rewrite

Check data redundancy of freshly copied files and track its integrity! A lot of methods available (some hints on the pinned forum topics too).

Besides: If a smart data tool is showing any sort of warning (block failure or what else)... the drive is usually "done"; as this is very critical if there is any visible failure there!!! Use warranty if possible! I got a zero tolerance there.

And of course, always keep several copies of a certain data on different drives. Yes, archiving huge data is not free.

But why?

That would also mean you wouldn’t be able to get any updates or bug fixes. If the version you downloaded happened to have a critical, game-breaking bug, you'd be stuck with it. I’m genuinely confused and trying to understand, what’s the reasoning behind this? Is there some logic to it that I’m just not seeing?

Buses, buses, bicycles. Try again. Motorcycles, crosswalks. This is getting old, GOG.

That's what I went through just to answer you. I have already explained myself several times. I will do so once more, then never again....

I waited and finally bought Cyberpunk when it was on sale. It cost me $29 something. I downloaded version 1.63, cause that is what my system (then) could handle.

I backed it up twice. The original 105GB zip on a thumb drive (verified it), than the individual files on two blurays. A 100GB bluray, and a 25GB bluray.

I experienced issues on all of my Windows computers, when I tried to copy the files (extracting from the thumb drive or copying from bluray). I think I uncovered a very rare bug in Windows, or it's something with the GOG team itself that put together the 1.63 version. Follow me so far? I'll go slow.

So in linux, I had no issues copying the files over. It was only in Windows, on two separate computers mind you, that it woudn't copy over.

Yes, of course I purchased the game. I purchase all my software. I only come to GOG because it's DRM free. Only reason.

As to why I deleted my account last year. I already explained it. I'm not into social media. I don't enjoy having an online presence. I thought I got all the games I wanted, so, of course I back everything up, I thought there was no need, and so closed my account. That's it. I will not explain this again.

If you got the identical data on your BD, and it was working on your PC before... then i see no reason why it should not work anymore, as long as the data is identical (every single bit).

The data on your "thumb drive" (no clue what it means exactly) may be corrupted... this is a common issue on such drives, because not made for long term storage.

Weird story...

The true question is if it is NOW corrupted or not. If it is corrupted... your Linux PC may not be of use and the Windows PC probably was unable to "handle" the corrupted data (this is possible)... it simply can not properly read it anymore if some critical informations are gone.

I give up. People don't actually READ what I'm saying. I'm done with this topic.

Is your copy of Cyberpunk working now, yes or no?

If so... whats the issue?

If it is not working or not passing the redundancy check... it is corrupted.


I guess he was looking to solve the "can not copy from BD to Windows, and as well not from thumb drive to Windows" but it works by using a Windows partition on a Linux system?!

Well... if the data is NOT corrupt, it looks like a file system issue... but it is almost impossible it only is affecting Cyberpunk and no other game.

I can copy that stuff "around" on my Windows PC without issues, and yes i got the CP V.1.63 ZIP.

Bitrot is a thing.

Aside from weird electric fluctuations due to hardware, there is also cosmic radiation which has a very small but non-neglible chance to flip bits.

Oh please do not make him a "mad cow" now,... he is already upset,

I try to understand as hard as i can, Apparently the data is not corrupt but he simply can not copy it over from any medium he got (BD and thumb drive is failing he said) to a Windows PC, with the exception of a Linux PC with a "Windows partition".

I just can say, Windows partition is NTFS and any storage can use this partition, the external drives too, and most OS can at least read NTFS. I see no reason why Cyberpunk is in need of a Windows partition on Linux, as Linux is the best data archive OS and can store any data without any workarounds.

Just weird this story...

Sure, i can as well store Linux or Mac files on a Windows PC but obviously i cant not "use it". Linux or Windows will simply read it (if possible, Windows may need exFAT) and store it on their own file system.

Perhaps he was using a file system Windows simply can not read...

Ultimately i can not reproduce this issue, as it works for me... no matter the drive i use.
Currently i can not make tests now, as my PC is totally busy with backups.

Well i was only storing the 1.63 Legacy ZIP package, because this was the very last of the "old game installer" previous to the more advanced game version which as well was way more of a resource hog. This version is still available on the GOG account, and stored on my drive.

The point is that having one local copy of data guarantees that data for zero time.

You need backups, redundancy, or checksums to have any chance of maintaining data long-term

It's as easy as 3-2-1

3 copies of data (so if only one goes bad you can tell which one is bad by comparing all three)

2 of those copies on different types of storage media (so that one specific type of failure doesn't affect the other(s)

1 of those copies off-site (so that local disaster doesn't result in the loss of your data.
