Ok. I got a lovely new 1 terabyte external hard drive from Santa Hubby. That should be enough space to last me for a while, I'd think. Anyway, in reading the documentation yesterday I discovered that it has been preformatted as FAT32 which has a maximum individual file size of 4 GB and partition size of 32 GB. When attempting to back up my laptop yesterday I quickly reached that file limitation. The documentation says I can reformat the drive as NTFS to overcome the file and partition limitations. This is probably a silly question, but should I go ahead and reformat the drive? Oh, I'm running XP, by the way, which is why the new drive was preformatted as FAT32... Also, when I tried to bring up my laptop this morning WITH the drive attached, my laptop never came up. However, when I removed it and powered my system back on, it came right up. Any ideas?
