Error code 2 using "p7zip", Fatal Error

[mabundis]

Configuration

• Keka version: 1.2.50 (4808)
• macOS version: 10.15.7
• iMac 14,3

Describe the bug

I have downloaded a file several times and tried to decompress it using Keka (as recommended by VW)
The file I download is located at: https://app-connect.volkswagen.com/mapupdates/download/#download
'Europe - Bundle 1'
I have now tried with two different version dates (one previous version, and the current version) with the same result.
I am trying to decompress the file to an SD card using the built in SD card reader.
The media I am using is an empty SanDisk Ultra, 32GB 120MS/s factory formatted (and later formatted on the iMac) as MS-DOS (Fat 32).
Each time, near completion of the decompression process, I receive the same result: Error code 2 using "p7zip", Fatal Error

To Reproduce

The error happens simply as part of the standard decompression process, near the end of its run.
I have copied the log file below, from my latest attempt.

Thank you for your help!

@mabundis you should be more specific on the file because the provided link displays a car model selection, the first option tried does not redirect to your file.

That said most probably you're hitting the 4GB file size limit on the FAT32 format. I'm unaware of the VW requirements, but probably you need to format that SD as NTFS or EXFAT so it supports >4GB files.

As a tip, that will enable you to write (format) as NTFS and EXFAT on macOS: https://github.com/tuxera/ntfs-3g

If you provide the link to your used 7z file (or all steps) I can assure this is the issue.

[mabundis]

Thanks much for your quick response:
In locating the specific file I am downloading, follow the prior link and . . .
#1 - the model to select is 'Golf Sportsvan from 2019'
#2 - the navigation system is 'Discover Media' (MIB 2)
#3 - the region to select is 'Europe - Bundle 1'
My apologies for not being more clear about this (I assumed I gave you the correct link without actually checking)

That said most probably you're hitting the 4GB file size limit on the FAT32 format. I'm unaware of the VW requirements, but probably you need to format that SD as NTFS or EXFAT so it supports >4GB files. <

Hmm, okay – that is interesting. All the research I did in exploring the VW side of things stated that one MUST use the FAT32 format. This is because the system where one ultimately loads the decompressed files into (the VW car computer) requires/uses FAT32. Still, I am happy to try anything that works in the end.
Yes, in reading the Keka log file it seemed like there was a 'size' problem somewhere, but I was unsure of what/where.

I will await your further feedback to see if you can confirm the actual source of the issue.
Please let me know if you need more detail.
TIA!

Thanks, now I've downloaded and checked that the extraction works properly. Also there's no >4GB file, so the FAT32 format is not an issue. I've successfully extracted it to booth the macOS disk and an external FAT32 formatted 32GB thumb drive.

• Just to discard try extracting it first to your macOS drive instead of the SD. If it works copy the extracted files to the SD and see if it returns any error.
• The most common issue is lack of space but you've said it's 32GB and empty. Anyway formatting again won't hurt. Also check there're no files in the Trash.
  

Another common issue is a broken file, but you've downloaded it multiple times (and different file versions). Anyway you can check the file integrity using the Terminal.app:

md5 /Users/marcus/Desktop/DiscoverMedia2_EU-AS_1810_V15.7z

This should return this string: e1037e1f7c0a4a40b727a4fe116c199e

aone@aONe-M1 ~ % md5 /Users/aone/Downloads/DiscoverMedia2_EU-AS_1810_V15.7z 
MD5 (/Users/aone/Downloads/DiscoverMedia2_EU-AS_1810_V15.7z) = e1037e1f7c0a4a40b727a4fe116c199e

If it does not return the same string the downloaded file is corrupted.

[mabundis]

I will check and try as you suggest. Thanks for the info . . .

MORE INFO: I just put the VW factory SD card into my iMac's card reader to check its actual format.
It reported MS-DOS (Fat 32) . . .
BUT, Finder could not see the SD card. I instead used Disk Utility to see the card and check its format.
Earlier, Finder could see the VW factory SD card, but not now.
I restarted my iMac in hopes of clearing things up – but then neither Finder nor Disk Utility could see the VW factory SD card.
Any thoughts to such odd behavior?

[aonez]

Faulty or dead SD card?

[mabundis]

Except that the VW factory SD card works fine in the intended/needed application (in the car's computer) . . .
I will let you know what happens.

[mabundis]

okay, like you said works fine this way . . . I seems to have a dodgy SD card reader that is causing my problems/confusion.
Sorry for bothering you!!

[aonez]

Well! That's the easiest and cheapest to fix, glad to hear that :)
