(1 star) Doesn't eject drives, drives don't fit, get stuck.

By: UnhappyWithStarTech
Thought this looked like good product, very disappointed! Doesn't eject the drives...I've tried drives by Intel, Micron, and WD...none work or fit correctly. Now my drives are scratched up from prying them out of the slots.

Matt, Customer Support
Product quality is very important to us and we're sorry to hear about the problems you've experienced with our HSB220SAT25B. This enclosure shouldn't be having any issues ejecting drives but is only compatible with 2.5" drives that are 9.5mm thick or smaller. If you're using drives thicker than 9.5mm that may cause issues with the ejecting mechanism. We take these reports seriously and would like to speak with you further regarding this issue. Please contact us at where our Technical Advisors are available 24 hours a day, 5 days a week to provide support.

(1 star) question about 'hot swap'.

By: sbumail
It seems to be understood that 'hot swap' means the ability to remove a HDD while the PC is **powered on** In your attached user guide, it clearly says at the top of Page 3 : "Please note: It is strongly recommended that the computer be POWERED DOWN when removing drives from HSB220SAT25B, as removing drives while in use can damage the drive and any data contained within." Is there some other device that needs to be connected between this and the PC to ensure the drives are powered down before they are removed??

(5 stars) Greatly Improved!

By: palmdesertpat
I've been using these hot swap drive bays for many years, we've sold hundreds of them with all the PC's we build. They have gotten better as time went by, but the best improvement was made recently. Startech added clip retainer slots for the SATA cables. Now when we connect the SATA cables the clips "click" and stay securely in place. Before this improvement we had to perform a number of techniques to hold the cables in place. This was always the weak link in our systems. Way to go Startech, you are definitely listening and improving your products!
