@CassRT WD may honour the warranty without a receipt as they know the production date from the serial number. This would be especially so in the case of a model that has a known issue.
As to the one month warranty by the repairer, you won't use them again. They however have supplied you a drive with 5 years warranty and although they may not cover labour the drive they sold should simply be replaced. They will probably say as you took it out they no longer are responsible, but that is BS. I don't know what country you are in or what the laws regarding such things are. Here in Oz we have a statutory warranty that means an item or repair should last as long as a reasonable person would expect and as the drive has 5 years then the whole warranty would be at least 5 years. Fighting them is another thing.
I hope you paid for the repair by credit card and it is less than 6 months ago. If so you can raise a recharge with your credit card provider on the basis you did not get what you paid for, refusal of replacement/repair of faulty item under warranty. Stick to your guns that if the SSD has 5 years warranty that they cannot say our warranty is only 30 days.
Your credit card provider will be on your side, I have had them fix quite a few issues for me and as such I always pay by credit card. So they get a loyal customer out of it which is the purpose of them taking your side. Credit Cards may be the last place left that the customer is number 1.
BTW I personally never buy another WD drive, I have had numerous issues and I do not like how you cannot use other drives in WD cases and that WD portable drives cannot be removed from the case and used in other cases, bays etc (the sata-usb interface is integral to the drive so if it fails and the drive is still ok you still throw the whole drive away. Now this is my personal opinion and yes other drives fail etc. AS far as SSDs I like Samsung, but there are other good brands.
