  1. You are correct -- I only scanned for FAT tables. I'll do a complete run with NTFS, if that's what you think is best, however, I'm ALMOST certain the Explorer DVR uses FAT. The (other) "MY Book" type drives are factory-formatted with NTFS - EXCEPT the AV version which is formatted with FAT 32. WDC "My Book AV" P/N: WDBABTOO10HBK-00 1411B S/N: WCAV5J064876T R/N: C4CBABCAA eSATA input USB 2 input The MyBook AV is not available at any of my local stores, so I've ordered on online. I'll eventually use it to copy/clone the data from the original drive IF any is available. But first I want to attach it to the Explorer DVDR. If it does not Format the drive, then I'll know for sure if it's a FAT. It may format the drive even if it is FAT, but it's worth a shot. After it's formated and ready to go, I'll attempt to copy the MBR, or whatever it uses, so I'll know what info it requires. Possibly that's where they store the "Code" that prevents the drive from working with a different machine. I'll see if that's true by trying it with a different Explorer DVR. I wouldn't mind finding a way to transfer the movie files to a different drive so I can edit them, and transfer them to DVDs. IF we can recover them. I'm committed to working on this drive until we recover the data or prove it's gone forever. Thanks for all your help!
  2. There's no way to get it out of the case, well no easy way... Attached are the current results for GetDataBack using FAT:
  3. What was the exact model of drive? I'll help you find a tare down (an instructional on how to open it up) Once it is open, connect it directly to a sata port. Once this is done we will have eliminated some of the guess work with the esata driver etc If it is showing up in the drive manager you should be able to run get data back for ntfs on it (even if it shows up as unallocated) EDIT: you can try this first... if you do get the data check the videos to see if they are all intact. There's something I forgot about doing data recovery on NTFS until just now. Unless the drive was recently defraged then chances of recovering large files (ie, video file) fully intact is low. You may recover part of the file, but the end of it could be corrupted, but you wont know until you try. My new suggestion: Use testdisk http://www.cgsecurity.org/wiki/TestDisk scan the disk with testdisk, it will tell you what partition MFTs it finds. It will most likely find the partition near the beginning of the HDD (usually sector 64 if i remember correctly) It will tell you what type of partition it is. It will then give you the option to write the correct partition map to the disk. After this you will need to re-boot to access the partition. ..one other thing I forgot about was to have you test to make sure the drive isnt failing. Use a program like HD Tune to make sure the drive is functioning correctly. If the drive is failing we could just be wasting our time. Let us know your progress! While I was exploring the drive's box for a way to open it I found a small rectangular area that appeared to be a cover. With a LOT of fussing I was able to remove it. I expected to find a screw or something... Would you believe that that under this UNMARKED plastic cover lurked a USB port? My computer found the drive , and under "Devices and Printers": NAME: WD My Book AV 1020 USB device LOCATION: port_#0003.Hub_#0008 Running GetBackData for NTFS under Win 7 PHYSICAL DRIVE DETAILS: 121601 CYLS * 255 DEADS * 63 SECTORS LBA SECTORS 1,953,525,168 (932GB) NO DRIVE LETTER NO PARTITIONS GetBackData is currently running and at 18% completed: Index Allocs: 0 Boot Sectors: 0 Files Identified: 5834 Starts, 0 USRDEF MFT entries: 0, 0 $MFT Master File Table entries ZERO? Does that mean no files???
  4. I will try it on other computers and let you know... The drive is enclosed in a plastic case with no obvious way to remove the drive. Booted with Hirens to MiniXP (SATA to compatability mode) - no luck detecting the drive with any program... After I rebooted back to windows, just for the hell of it I retried Disk Management via Admin tools. The eSATA drive appears without a drive letter as UNALLOCATED space of about 1TB. Also, it shows up in Device Manager (it's an additional drive anyway) as WDC WD10EVVS which doesn't match the drive model, but it is Western Digital. Next with the UNKNOWN DEVICES program, the eSATA drive DEFINITELY is detected. It shows up as WD My Book AV 1020 USB device with correct Hardwarde ID and the Enumerator - USBSTOR. That's the second time it is referred to as a USB device. Apparently, I need to start looking for it as a USB device, although it is MOST DEFINITELY plugged into an eSATA connector!
  5. Correct. ONLY Parted Magic detects the disk, and I agree that was a surprise. The disk does NOT appear in Device Driver nor does appear using the Admin tools to force a rescan of the drives. Although I do have Hirens burned onto a disk, I did NOT boot with it. I ran the programs from the disk under windows per your advice. The only thing I was able to learn is that the Disk Partition and File System are UNALLOCATED.
  6. Thanks for the advice Mack, I have Hiren's Boot DVD. I have tried EVERY program on the disc, and only Parted Magic detects the eSATA drive. It displays all the WD data correctly including the drive size. It reports the PARTITION and FILE SYSTEM as UNALLOCATED, so I still don't know which file system is used by the SciAtlanta 3800HDC. If the drives are somehow marked with a code so they will only play on a specific DVR, then there's no reason for a proprietary format for copy protection. My plan is to pick up another eSATA drive, format it with a FAT partition, plug it into the DVR and see if it formats the disk. If not then a FAT partition is what it uses. If it formats the drive, then I will try a a Linix format, and repeat the procedure. If I can determine the type format used, it will be a good start towards either reading the data off it, or repairing the drive. Of course, the DVR may automatically format a new drive regardless of the format already present... Or they may use their own format for whatever reason.
  7. I THINK it does. The drive orginally had an NTFS format. When I attached it to the 8300, the DVR insisted on formatting the drive again. So unless they use some type of proprietary format, for the moment I'm thinking it could be a FAT. I've tried a bunch of programs to try and ID the format, with no luck. "Parted Magic" easily found the drive, and reported it had no problems. I couldn't find a way to display any format data, though. I'm wondering if Win 7 messed with the Master Boot Record in an attempt to read the disk... Trying to do some research in that direction at the moment.
  8. Thanks Mack! I'll wait to see what you come up with. I'd be happy to post. I'm still prowling around the site to see if I can answer any questions.
  9. My first post here... Sure looks like an "interesting" site! I attached a WDC eSATA drive to my Explorer 8300HDC (with DVR) for added storage space. It worked without a problem. My wife plugged this same drive with dozens of movies on it, into her computer thinking she could watch a movie on her Laptop. Windows couldn't find the drive, so she gave up and plugged it back into the DVR. Now the DVR doesn't recognize the drive, and asks to format it. I REALLY don't want to lose all those movies! Win 7 must have done something to the drive without asking, because she is certain she didn't do anything beyond looking to see if the drive was recognized by Device Manager (it wasn't). Does anyone know which file system Sci Atlanta uses on their DVRs? I'm thinking if I can find a way to read the drive, I can see what was changed in the Master Boot Record or whatever and possibly repair the damage. Any recommendations as to a program that would allow me to find this disk and read it would be greatly appreciated. Thanks for ANY thoughts, Tom
