Multi Volume Disk Full - How to recover?

[earthzen]

I created a multi volume Deflate64 archive with maximum file size of 15,000 KB. I set the options to move the files to the archive and delete the original files.

:eek: I ran out of disk space during the process. It did not create the main multi volume zip file. It created a partial multi volume file (z731) and a bunch of zero byte files (z732 … z759).

I tried using pkware to open z01. It asked for the location of the last disk but would not accept the directory name. Powerarchive says z01 is not a valid archive.

Is there any way to recover these files?

Thanks,
Forrest

Mult Volume files created;
15,000 KB files - downloads.z01 (…) downloads.z730
3,304 KB file - downloads.z731
zero byte files - downloads.z732 (…) downloads.z759

Below are my settings for the “Add” dialog box on the Options Tab.

Action: Move Files
Compression: Maximum (slowest)
Profile: ZIP Default
Additional Options: Include System and hidden files
Advanced ZIP Options: Use Deflate64
Multiple Disk Spanning: Cuistom
Max. volume size: 15000 kBytes
Mode: pkZip/PA 7.0 Compatible
Zip Encryption: Disabled

Obvious things first:

!) What OS?

2. Did you create archives on the same Drive / Partition as the files?
3. Do you have another Drive/Partition to work with?
4. What is the size of your Drives/Partitions?
5. What were the original files?

If the answer to 2) is yes - then do not create any new files/directories (or copies) on it.

Thank you for your reply!

Below is the additional information.

Thanks,
Forrest

!) What OS?
Windows XP home addition.

2. Did you create archives on the same Drive / Partition as the files?
   Yes, I created them on drive two partition G:

3. Do you have another Drive/Partition to work with?
   Yes, I’ve already cleared additional space off.

4. What is the size of your Drives/Partitions?
   Drive 1: Western Digital WD1600BB-22FTA0 Capacity: 160 GB
   C: Capacity: 80 Used: 52 Free: 27 NTFS % Used: 65
   Capacity: 32 Used: 11 Free: 21 FAT32 % Used: 35
   E: Capacity: 40 Used: 20 Free: 19 NTFS % Used: 51
   Totals Capacity: 152 Used: 83 Free: 68 % Used: 55

Drive 2: Maxtor 6Y080P0 Capacity: 80 GB
G: Capacity: 42 Used: 25 Free: 17 FAT32 % Used: 60
K: Capacity: 35 Used: 26 Free: 8 NTFS % Used: 76
Totals Capacity: 78 Used: 52 Free: 25 % Used: 67

5. What were the original files?
   Many different kinds (EXE, TXT, PDF, ISO, ZIP, RAR, etc.)

I created them on drive two partition G:
…
Drive 2: Maxtor 6Y080P0 Capacity: 80 GB
G: Capacity: 42 Used: 25 Free: 17 FAT32 % Used: 60

Yes, I’ve already cleared additional space off.

Is that correct?
On this drive you tried to create an archive of ~15M*760 = ~1.275GB
You have 25GB free and it failed because the drive was FULL?

Something seriously wrong here…
You didn’t clear the additional space on this G:drive I hope?

I don’t know if you can recover anything from the incomplete split Zip.

Hopefully, spwolf or Ivan will chip in on that.

Are the original files (not the Zip archives) still in trash/recycle bin?
Maybe you need an “undelete type” tool?

For future reference:
Deflate64 on RAR,PDF,ZIP, ISO is not a good idea as they are already compressed,
just store them into split Zip.

What version of PA was it?

[earthzen]

I under estimated the hard space I would need by a few gig. I won’t make that mistake again, but I really need to recover the files left in the multi volume archive. I was just looking for a quick way to clear essential files off the 160 gig drive so I can repartition and install several operating systems. To do this I needed to clear some space on the 80 gig drive.

Yes, I cleared the additional space on G: drive. No, there is nothing in the recycle bin. I have archived and moved other files since this happened.

Here are the settings for file size when spanning volumes. I wanted the option of copying to a FAT32 partition so I kept the file sizes under 2 gig.

Multiple Disk Spanning: Custom
Max. volume size: 15000 kBytes

15000 kBytes = 1.5 Gigabytes
760 * 1.5 GB = 11.40 Gigabytes

Thanks,
Forrest

The version of PA I am using is Powerarchiver 9.01.01 (August, 2004).

[TBGBe]

15000 kBytes = 1.5 Gigabytes 760 * 1.5 GB = 11.40 Gigabytes

No (approximation ignoring decimal/hex argument) -

1 GB {Giga} = 1000 MB {Mega}
1 MB {Mega} = 1000 kB {kilo}

So 15000 kB = 15 MB

Whereas
1.5 GB = 1500 MB = 1500 000 kB

For intended 11.4 GB -> did you activate “Make Large Zip File (over 4GB)” ?

But too late now

I’ll leave it to spwolf regarding recovering files from incomplete spanned Zip.

[earthzen]

Your right! Oooops! Been awhile since I did the numbers. :p
14.6 MB (15,360,000 bytes)

:eek: Me too - ~15M*760 = ~11.275GB

So, now on G: you still have (zip…Z731) files which are valid -
Which is about 10.9GB correct?

[davidsplash]

you could try repairimg the file using the file repair or you could try winmzip as they might be able to sovle your problem but if that fails then i would try advance zip repair. if that failes powerarchiver which might work but as you’ve tried that the only hope then is that the file can be recovered by someone canbn you post it here so we can try to recover the files for you.

For safety, only do this with copies of your Zip Files - otherwise you might lose them completely.

@davidsplash:

Cannot attach 10GB !!
Or even first couple (15MB each)!!

[earthzen]

Sorry for the delay. I’ve tried a few things but still have not been able to access the files.

I have resolved myself to the fact I may not be able to recover the files. I am continuing mostly out of curiosity now.

I have combined the files into one file using the instructions here;
http://www.repairfile.com/faq.htm

10.3 GB (11,089,920,000 bytes)

I tried “Advanced Zip Repair” but it locked up. It may have had problems because I was using to many system resources. I’ll try to rerun it overnight.

I am looking into the structure of zip files at this link;
http://www.pkware.com/company/standards/appnote/

I am using this hex editor which handles large files;
http://www.sweetscape.com/010editor/

If I find anything new I’ll make a post.

p.s. davidsplash - I’m not sure if winmzip was a mispelling as I cannot find any information on it. Besides “Advanced Zip Repair”, I have tried powerarchiver, pkzip, zipzag, and winzip. None of them will open the file.

[davidsplash]

meant winzip. However it might be good to put the file to gether ie. link it up to one then have a go

[spwolf]

@davidsplash:

its 10 GB :-).

Anyway, Forrest - you are at correct track, it would be a lot of manual work but that is the only way…
