Not necessarily so, one of the SCSI drives purchased from fleabay the OS loaded fine but you could hear the bearings were on their way out. Fortunately the vendor is sending a replacement at no cost to me.
Sata spins at 7500 RPM, SCSI usually run at 10,000 rpm but there are 15,000 rpm drives as well, four or five years running in a commercial environment day after day is going to take its toll on the bearings.
This is why putting a screwed up hard drive in the freezer for a couple of hours sometimes will bring it back to life long enough to remove data, the cold shrinks the bearing making it tighter as long as it stays cold. Once it warms up your back to square one, so you better be quick recovering your data because the freezer trick doesn't always work.
Having come to the conclusion that previously used hard drives are nearing their end of life, I decided to purchase a brand new drive with a visible date of manufacture, no more used drives for me.
A used 146 gb SCSI sells in the neighborhood of $100.00 for an extra $30.00 I have a brand new one coming plus the replacement drive, which will be sound tested before i leave feedback.
