Hey, thanks for reading my post.
Summary: I'm trying to do a low-level reformat of two identical drives. One took 2 hours to complete and the other says it will take 14 hours... and it's already been going for 3 hours. Why the difference?
Longer version: I have two identical drives from the same manufacturer that I use in RAID-0 for Photoshop and Video scratch. A few months ago, one of the drives started to act up and I got an I/O error message. I broke up the RAID and reformatted the drives but never put them back into RAID; I wound up using them individually as short term storage drives. After I reformatted them, they both passed drive tests and there has been no problems since.
I usually do computer house-keeping over the holidays and decided to put the two drives back into RAID-0 for a fast scratch disk (I don't store longterm data on them). I have a big project coming up and need a fast scratch disk. Anyway, I decided to zero out the disks to make sure any bad blocks that have deveoped over time are mapped out. The first drive zeroed out in a bit over 2 hours. The second has been going for 3 hours and it says that it's going to take 14 hours more! I thought that maybe I selected the more advanced reformat that requires multiple passes so I stopped the formatting to double check. Nope, it's set on basic one pass zeros.
Sorry for the long post, but does anyone know what might be going on here? Do you think the drive is defective? I ran a simple reformat and drive check before I started the low level format and the drive passed. Even if it passes the reformat, I'm left wondering if there is a major issue with the drive that isn't showing up in tests. 16 hours++ to zero out a 320GB drive is insane! Especially when the other exact model drive only took 2 hours.
Thanks for any insight you can provide!
