I format the drive and benchmarked it, the drive is reading at 500kb/s to 2Mb/s and around 890ms access time. but when it was new it read at 28-30Mb/s. It behaves this way on more than one machine and all other programs are closed during the benchmark
I tried to copy files to it now that it's format, and it took ages!!! just to transfer a 200Mb file it took like 10 minutes. This used to take maybe 1 minute.
I keep having this issue with Western Digital drives, is this a common problem with them? or just my luck?
What would cause a hard drive to do this? It still holds the data, there is no clicking hard drive failing sounds, it still reads and writes but it does it at such slow speeds it feels like I'm writing to a floppy drive.
Being how the drive was fast at first and became slow, it shouldn't matter but It's USB 2.0, I tried it with and without write cache on the drive with the same results, this is Windows 7 but the drive access is also slow in Ubuntu on my other USB 2.0 machine.
I think I can RMA it back to the factory as it's under warranty but I just want to know what causes this, if anyone has similar experience or could recommend an external USB drive that doesn't do this.
Thanks for all your answers
