Funny story about these drives.
I used to have a 4.3gb one (CY? can't remember). Anyways, it ran for several years without a hitch, and then when I was in college it developed a strange symptom: when the computer was started from dead cold, the drive would "sing", like you were running your finger around the edge of a wine glass. It would only do this once the drive stepped to a certain spot on the disc. The drive accesses at that point would fail until the drive warmed up for about 5 minutes or so. I circumvented this by hitting the pause key during POST and waiting the five minutes before letting the system finish booting.
After about a year of this I started getting the ol' click of death and figured that if I didn't get the data off the drive soon, I wouldn't get a chance. So, I went to Best Buy and picked up a brand-new Maxtor 3.5" drive, and successfully transferred everything off of the drive. A couple days later, the BRAND NEW DRIVE FAILED, and the data on the Quantum was only partially recoverable (thankfully most of the damage was in the OS section). I did the ol' take apart thing, and discovered that under the warranty void label in line with the head pivot, the nut had completely backed off! I tightened that back down and the singing sound went away.
Who knows how long it would have lasted if I had done that sooner. lol.
