Could someone tell me why one hhd will be noisy, and the next of the same modle from the same shelf not make any sound at all wile running? I've found some to have a high pitched whine to them even though it will funtion just fine.
I've got 2 Western Digital, WD400 EIDE drives that are used for back up files. Both are a year old. one makes no sound, the other whines. I've also got 2 out of production Maxtor 20 gig EIDE dirves, that I can only describe as "way old". Again one makes no sound wile the other whines. All four operate just fine and have given me no problem, so there is no performace issues. just wondering about why one would be louder than the other.
I dont think there is a real "answer" to this question. These are mechanical devices and they are built on an assembly line. Not all drives will be created equal. one bearing that is not perfectly round or whatever will create some noise. It is a problem in the manufactuing process and QC.
