External drive capacity suddenly changed!
I recently bought a used 160GB 7200RPM USB External. I received it, and it's capacity was shown to be ~160GB. I put about 30GB of files on it. About 2 weeks later, I was trying to copy to it and I got a disk full error. I checked the capacity in My Computer and it only read 30GB! The tooltip that appears when I hover over the drive's icon in My Computer reads, "Total Size: 29.3GB!" I've tried reformatting in both FAT32 and NTFS formats, and it still shows a capacity of only 30GB. I thought, maybe it actually is a 30GB drive in there and I didn't realize it when I first got it. So, I opened the enclosure and verified that it was a Seagate Barracuda 160GB drive. I am stumped. I have never had a problem like this before. Any ideas as to what it might be?
