Invisible files on external hard drive

[Amigosdefox]

I have a Iomega 250GB external hard drive. I partitioned it with 80 GB as FAT32 and the rest as macintosh file system.
I was using the pc partition and had several files ther (20 GB).. I was using the drive with a pc an disconnected it. After reconnecting it to the pc the drive was detected but no files were visible inside the it. It still show that there are 60 GB free and that it has a total space of 80GB. I tried connecting it to another pc and had the same problem.
Any clue to what happened?. Is there a way to recover the files?

Did you "safely remove" the drive before unplugging? If not, then the filesystem got corrupted and the data was never written to the disk either.

You most certainly cannot recover all of the data although file recovery software may be able to get something back.

You can try to fix it using chkdsk or just reformat the partition.
