Any ideas appreciated on...

Recorded a couple sets this weekend. ACM HD-P2 / Kingston Elite Pro 8GB CF recorded just fine, though I had trouble with not enough gain for the C34 (as expected). Had trouble with my V3 > stock HD-P2 / PQI 8GB CF. What I've experienced / steps I've taken so far:
<01> Original recording sourceEncountered no noticeable problems during the initial recording session: Schoeps MK5 / KC5 / CMC6 > ACM V3 (24/48) > stock HD-P2 / PQI Hi-Speed 100 8GB CF card
<02> Transferred filesTransferred files from the PQI CF card to PC via Lexar Pro CF reader (firewire), not the HD-P2
<03> Error message opening filesUpon attempting to open one of the files in CD-Wave, received an error like "Bad FMT descriptor" or some such. Can't duplicate the error and forgot to note the specific text of the message.
<04> upon successful open: noise / artifactsTried opening a second time in CD-Wave and...success.
So, I opened in Samplitude SE v8 to take a closer look. However: HUGE noise / artifacts starting at ~37min and 35min into each of the two ~45min sets. See attached screenshots (01 = zoomed out, 02 = zoomed in a bit) and MP3 sample for a listen.
Caution: the sound source is very quiet at the start; the noise starts at the ~20 sec mark and it's LOUD (as you can see from the screenshots), so keep the volume down.
<05> Re-transfer attemptTried inserting the CF card into the stock HD-P2 to re-transfer. P2 indicates something like: "Media needs formatting. Format now?" Of course, I did NOT format.
<06> Ran CHKDSKPut the card back in the CF reader and ran CHKDSK /F from the command line. Message indicated it wasn't a Windows 2000 disk, asked if I wanted to continue, I said Yes. Message asking whether I wanted to save the bad links / lost chains to a file and I said Yes. The results:
Bad links in lost chain at cluster 28286 corrected.
Lost chain cross-linked at cluster 28287. Orphan truncated.
Bad links in lost chain at cluster 28424 corrected.

Cannot write boot sector.<07> Read card againAttempted to read the card via the CF reader from the DOS prompt, and received the following message:
The volume does not contain a recognized file system.Tried again in Windows and received a message that the card needs formatting.
<08> Additional card read and copy attemptRebooted, tried to read the card again in Win Explorer via the CF reader and...success! Card contents:
- Proj05 directory + XML files
- Proj05/Audio files directory + my recorded WAVs
However, tried to re-copy from CF card to PC and received the following error:
Cannot copy <filename>: The file or directory is corrupted and unreadableTried copying the XML files for kicks, and they copied fine. But the WAVs still do not.
<09> Ran CHKDSK againRan this time not from the command line but from within Windows:
Properties | Tools | Check, ticked the
Automatically fix file system errors checkbox, did not tick the
Scan for and attempt recovery of bad sectors. Result:
Windows was unable to complete the disk check.<10> Read CF card againAgain tried to read the CF card via Win Explorer, only to receive message (again):
The disk in drive L: is not formatted. Do you want to format it now? Of course, I said NO.
<11> Read CF card once moreUnmounted the CF reader, re-mounted, and succesfully read the card again. BUT, contents have now changed. Card now includes:
- Proj05 directory + XML files (same as before)
- Gone: the Proj05/Audio Files directory + WAV files
- New dir: FOUND.000
- New files: FILE000.CHK sequentially through FILE999.CHK, total size of 312 MB
Attempted to copy the entire directory structure and files only to receive the following message midstream:
Cannot copy file FILE8574: Cannot find the specified file. Make sure you specify the correct path and filename.Re-read the card to verify FILE8574.CHK exists, and...FILE8574.CHK through FILE9999.CHK are GONE.
However, there's another
new directory named:
gibberish** Copied the dir name into a text file and tried to include in my post, but TS won't preview or post with the funky characters in the thread.
Attempting to read the oddly named directory returns the following message:
L"\FOUND.000\<gibberish> is nto accessible. The filename, directory name, or volume label syntax is incorrect.Tried re-naming the directory to
WTF and could not. WTF!!
<12> Read CF card once moreUnmounted the CF reader, re-mounted, and succesfully read the card
again. Files FILE8574.CHK through FILE9999.CHK are now...BACK. Tried to copy FILE8574.CHK through FILE9999.CHK once more. Result:
Program error. Explorer.exe has generated errors and will be closed by Windows. You will need to restart the program.Tried copying small groups of files with some success:
FILE9999.CHK - FILE9900.CHK | Success!
FILE9899.CHK - FILE9800.CHK | Success!
FILE9799.CHK - FILE9700.CHK | Success!
FILE9699.CHK - FILE9600.CHK | Success!
FILE9599.CHK - FILE9500.CHK | Success!
FILE9499.CHK - FILE9400.CHK | Success!
FILE9399.CHK - FILE9300.CHK | Success!
FILE9299.CHK - FILE9200.CHK | Success!
FILE9199.CHK - FILE9100.CHK | Success!
FILE9099.CHK - FILE9000.CHK | Success!
FILE8999.CHK - FILE8900.CHK | Success!
FILE8899.CHK - FILE8800.CHK | Success!
FILE8799.CHK - FILE8700.CHK | Success!
FILE8699.CHK - FILE8600.CHK | Success!
FILE8599.CHK - FILE8574.CHK | Success!
So...eventually successfully copied all 10,000 files.
<13> Ran CHKDSK once more, copy fragmentsSince I successfully copied the file fragments after the previous CHKDSK, I ran it again for kicks. This time, 525 files: FILE0000.CHK - FILE0525.CHK. In attempting to copy them across, turns out there are two (yes, 2) files each of FILE0510.CHK through FILE0525.CHK. Tried to copy a single set of FILE0510.CHK > FILE0525.CHK, plannig to rename to FILE0510a.CHK > FILE0525a.CHK, then copy the duplicate set and rename to b. BUT, when I select and copy only a single set of FILE0510.CHK - FILE0525.CHK, Windows copies a pair of each file. WTF
And now...I give up, and am at a complete loss. I was initially encouraged by the 10,000 recovered files after running CHKDSK in Windows the first time. But then I realized the files only account for 312 MB. The 525 files after the 2nd CHKDSK account for only 16 MB.
And if you've gotten this far...
I'm at a loss. I'd like to re-transfer, but can't at the moment.
