Hey, sure could use some expert help here :-)
I was noticing that my internal drive kept working very slowly and then started corrupting very quickly....(was running 10.2 - 10.2.6) I wipped it several times did reinstalls used DiskWarrior to repair it and then I started noticing that it was corrupting partitions on my external disk drive. I had addressed some odd drive behavior with Apple last Winter and they actually took a look at it and replaced the drive cable and said everything was fine. I've run the Hardware Test disk on it and everything checks out fine even Disk Warrior said the hardware was fine. I decided to replace the drive...I needed more room anyway. The new 40GB drive had trouble right after formatting it. Volume Header/Information trouble just as the old drive had and my external drive continues to have. I have a PISMO/400.
Any ideas on what could be playing havoc with my drives?
