Why does my ps3 freeze when I try updating it?

Alright, so I took a 1 Terabyte Seagate Momentus-B external hard drive. It worked prior to me doing this, and decided to try and put it into my ps3 slim. I put it in, and it came up with a screen asking me to insert a storage device with the 4.5 update or later. I took a flash drive, and put the update on it, exactly how the playstation website told us to do so. I insterted the flash drive. A screen came up saying the hard drive needed to be set to the correct format. So I did, and it started to format the drive and the ps3 froze. So we took it out, and reinserted the original hard drive. It asked for the 4.5 update again, so we used the flash drive again. It started to update, and stopped at 99%. The ps3 doesn’t freeze, just the update. I’m stuck now. Do I need a new hard drive?
