Rescuing a corrupt partition

So I'm trying to fix a machine for someone. It's an Acer desktop machine running XP Home. It came with two visible partitions (system and data, effectively) plus one invisible one with the system restore stuff on. It was bluescreening on boot everytime, so I did all I could to either boot in safe mode, or run a repair off a Windows CD. Nothing worked. In the end, I tried a fixmbr from the repair console. This made a big difference. Now the 'C:' partition is absolutely hosed.

If I boot from the Windows CD and use the recovery console to look at the available partitions, it sees only the C: and D: partitions. I should mention at this point that there is very (sentimentally) valuable data on the C: partition. If I examine the contents of that partition from the recovery console, it contains just nonsense files and directories. Files with names full of illegal characters, and directories I cannot enter.

Booting from a Knoppix DVD really just reveals the same thing. It sees the partition, and it also reports lots of files with nonsense names. I can't copy them to a USB stick, or over the network, because the names are illegal.

Does anyone know of a tool that will fix the FAT, or whatever it is that's knackered, in order to retrieve the data on it? I don't know for sure what it's formatted with, but as it's XP, there are obviously only two likely options. I've checked with the disk manufacturer's software, and the disk itself seems to be fine; it's just the FAT (or whatever) that's wrongheaded.

I have told the chap in question to expect the worst, but it contains all of the photos his daughter's ever taken over the last 10 years. I have also hammered into him the importance of backups, so there's no need to go over that with me.

Cheers, I hope, in advance.
 
Runtime Software's GetDataBack will usually recover files from this - it's the best software for NTFS/FAT file recovery I've used, though you may have to mount the hard drive onto another computer to use it (I don't know whether you can get a bootable or DOS-based version). I'd advise against using any software which claims to actually "fix" the partition because in my experience they often just make it worse. Get the data off, remove all the partitions, start from scratch :)
 
Used to be that Norton's Utilities was good for this type stuff. Haven't had an occasion to use it in years though, so I'm not sure where it stands these days.

Moopet's idea of moving the drive to another computer is certainly good advice IMHO. It may be that simple to pull the data you want off the drive. Then format/install the operating system of choice, and copy the files back. This would take a few moves back and forth, but if your handy with such things, it shouldn't take that long.

ETA: Missed the part about the illegal file names. Probably won't be as simple as moving it, since it does appear that the FAT is hosed. There should be a 2nd FAT though. Norton's of old, and perhaps the program moopet mentioned can read the 2nd FAT and repair things.

Good luck :)

Not to be a downer, but having run fixmbr and having the contents of the partitions scrambled, I'm going to say you're very likely out of luck, without spending a lot of money.

Using fixmbr to create a new boot record, can do funny things to the partition table. That you can see them period is a good thing, but getting anything off them, especially if the partition table has gone screwy is pretty leary. Their are plenty of companies that will do what they can to recover data of damaged drives like that, but it usually comes at a premium. Say $1400 Cdn as an example to recover data of a failed drive.
 
Yes, I've looked at prices before for data recovery services, and it's not good. I'm going to try the software suggested and see what happens as soon as I can, and I'll let you know, and sing all of your praises, if it's successful.

Cheers.

I second this. The software is fairly inexpensive and has worked for me each time I've used. About 6 times. If it's a big hard drive it'll take awhile to run.
 
uneraser.com has a trial version.

when tinkering with partitions, i sometimes make a copy of the MBR/PT with dd.
 
i'd image the disk. either to optical media, or directly to another drive. that way you can restore it at your leisure, as well as keeping further damage to a minimum.
 
Try Digital Photo Recovery. The program is initially a free download; it will show you what it can recover. Then, if it works, you can drop the $30 on the program.

I've had wonderful luck with it; it's been able to recover pics from digital camera memory as well as hard drives.

Thanks all for your suggestions. I tried GetDataBack first, and it worked perfectly. Loaded up a machine with Windows (took less than an hour ;)) and installed it. Plugged in the knackered drive and ran the software, and it recovered almost every file. It worked so well, in fact, that I will now pay for it, not least as the cost is recoverable.
