I need a replacement disk for our MD3200i, 600 GB, 15k drive. Apparently w347k disks are no longer manufactured. A vendor shipped me a 2 1/2" V5300 in an adapter tray instead, and said that replaces it, but it will not slide into the slot - the drive connection is different. What is the correct drive I should by to replace the w347k?

Thanks,

Ken
